Todo empez&oacute; en 2020, cuando decid&iacute; venir a Costa Rica para participar como voluntaria en proyectos de conservaci&oacute;n de tortugas marinas en el Caribe, con Pacuare Reserve y Sea Turtle Conservancy. Lo que iban a ser cuatro meses se convirtieron en nueve&hellip; y en una decisi&oacute;n de vida: no quer&iacute;a dedicarme a otra cosa que no fuera la conservaci&oacute;n de las tortugas marinas.<br />&#8203;<br />En 2021, continu&eacute; mi camino en la Pen&iacute;nsula de Osa, trabajando como coordinadora del programa de tortugas marinas en Osa Conservation. Adem&aacute;s de proteger nidos y realizar monitoreos a largo plazo, empec&eacute; a incorporar algo diferente: el uso de drones t&eacute;rmicos para observar tortugas durante la noche.</div> <hr style="width:100%;clear:both;visibility:hidden;"></hr>  <div class="paragraph">Ese mismo a&ntilde;o empezamos a evaluar con precisi&oacute;n el alcance y la eficacia del monitoreo a&eacute;reo y en 2022 publicamos un estudio pionero, el primero en demostrar que los drones t&eacute;rmicos pueden ser m&aacute;s eficientes que los m&eacute;todos tradicionales (<a href="https://www.frontiersin.org/journals/conservation-science/articles/10.3389/fcosc.2022.954791/full" target="_blank">leer publicaci&oacute;n aqu&iacute;</a>). Descubrimos que detectaban un 20% m&aacute;s de actividad de anidaci&oacute;n que los patrullajes humanos en la playa. Adem&aacute;s, lograron identificar rastros, depredadores e incluso actividades humanas que hab&iacute;an pasado desapercibidas durante los recorridos a pie, mostrando el enorme potencial de esta tecnolog&iacute;a para el monitoreo no invasivo de tortugas marinas. En 2023 llevamos esta tecnolog&iacute;a un paso m&aacute;s all&aacute;, aplic&aacute;ndola durante una arribada, esos eventos de anidaci&oacute;n masiva que son un espect&aacute;culo de vida y esperanza.<br /><br />Y el a&ntilde;o pasado inici&eacute; una nueva l&iacute;nea de investigaci&oacute;n en colaboraci&oacute;n con la ONG Kuemar: monitorear tortugas y otra fauna marina en el agua. Esta vez, los drones nos permitieron observar algo que rara vez se documenta: el comportamiento de los machos, ya que la mayor&iacute;a de los estudios se basan en hembras cuando salen a anidar. Pudimos registrar comportamientos de apareamiento, alimentaci&oacute;n e interacci&oacute;n, y tambi&eacute;n identificar amenazas reales, como pr&aacute;cticas de pesca irresponsables, contaminaci&oacute;n pl&aacute;stica y la presencia de otras especies marinas vulnerables como rayas, tiburones y peces costeros.<br></div>  <div class="wsite-video"><div title="Video: oct_27_122.mp4" class="wsite-video-wrapper wsite-video-height-480 wsite-video-align-center"> 					<div id="wsite-video-container-473057932201179415" class="wsite-video-container" style="margin: 10px 0 10px 0;"> 						<iframe allowtransparency="true" allowfullscreen="true" frameborder="0" scrolling="no" id="video-iframe-473057932201179415" 							src="about:blank"> 						</iframe> 						 						<style> 							#wsite-video-container-473057932201179415{ 								background: url(//www.weebly.com/uploads/b/11667209-923600401242266428/oct_27_122.jpg); 							}  							#video-iframe-473057932201179415{ 								background: url(//cdn2.editmysite.com/images/util/videojs/play-icon.png?1760628286); 							}  							#wsite-video-container-473057932201179415, #video-iframe-473057932201179415{ 								background-repeat: no-repeat; 								background-position:center; 							}  							@media only screen and (-webkit-min-device-pixel-ratio: 2), 								only screen and (        min-device-pixel-ratio: 2), 								only screen and (                min-resolution: 192dpi), 								only screen and (                min-resolution: 2dppx) { 									#video-iframe-473057932201179415{ 										background: url(//cdn2.editmysite.com/images/util/videojs/@2x/play-icon.png?1760628286); 										background-repeat: no-repeat; 										background-position:center; 										background-size: 70px 70px; 									} 							} 						</style> 					</div> 				</div></div>  <div class="paragraph">Todo esto me ha confirmado algo: la tecnolog&iacute;a puede ser una gran aliada de la conservaci&oacute;n, si se usa con sensibilidad y prop&oacute;sito.

It all started in 2020, when I decided to come to Costa Rica to volunteer on sea turtle conservation projects in the Caribbean, with Pacuare Reserve and Sea Turtle Conservancy. What was supposed to be four months turned into nine... and a life decision: I didn't want to dedicate myself to anything other than sea turtle conservation.<br /><br />In 2021, I continued my path on the Osa Peninsula, working as the coordinator of the sea turtle program at Osa Conservation. In addition to protecting nests and conducting long-term monitoring, I began to incorporate something different: the use of thermal drones to observe turtles at night.<br /><br />That same year, we began to precisely evaluate the scope and effectiveness of aerial monitoring, and in 2022 we published a pioneering study, the first to demonstrate that thermal drones can be more efficient than traditional methods (<a href="https://www.frontiersin.org/journals/conservation-science/articles/10.3389/fcosc.2022.954791/full" target="_blank">read publication here</a>). We discovered that they detected 20% more nesting activity than human patrols on the beach. Furthermore, they managed to identify tracks, predators, and even human activities that had gone unnoticed during foot patrols, showing the enormous potential of this technology for non-invasive monitoring of sea turtles.<br /><br />Y el a&ntilde;o pasado inici&eacute; una nueva l&iacute;nea de investigaci&oacute;n en colaboraci&oacute;n con la ONG Kuemar: monitorear tortugas y otra fauna marina en el agua.

Ambas investigaciones colaborativas fueron realizadas en todas las localidades de los 11 pa&iacute;ses que comparten la costa del Pac&iacute;fico desde M&eacute;xico hasta Chile y que forman parte de esta red internacional. Los resultados principales fueron que la gente de todos los pa&iacute;ses est&aacute; preocupada de la basura, y que la mayor&iacute;a de la basura tiene fuentes muy locales.

En el oc&eacute;ano, basura flotante est&aacute; ocupada por organismos que crecen sobre ella y son transportados por las corrientes. Se realiz&oacute; una investigaci&oacute;n colaborativa con estudiantes de la Escuela de Playa Grande, en playa Grande, Parque Nacional Marino las Baulas, en Santa Cruz de Guanacaste, Costa Rica. &Eacute;sta comprendi&oacute; una encuesta de percepci&oacute;n y an&aacute;lisis de interacciones bi&oacute;ticas en desechos costeros con el fin de determinar la percepci&oacute;n que tienen las personas de esta localidad sobre el problema de la basura marina, y las interacciones bi&oacute;ticas y organismos adheridos a la basura que son m&aacute;s frecuentes en esta playa. Se realizaron un total de 11 encuestas, en el cual la percepci&oacute;n de los entrevistados es que los desechos provienen principalmente de los turistas que llegan a este sitio. Se analizaron muestras de basura en el que la gran mayor&iacute;a de los objetos se compone principalmente de pl&aacute;stico y presentaron pocas interacciones bi&oacute;ticas. Ambos estudios sugieren que la basura en las playas tiene principalmente fuentes locales, por lo cual una estrategia de educaci&oacute;n ambiental en la localidad es herramienta importante para combatir este problema.</span></span></div>  <div class="paragraph"><strong>1. Introducci&oacute;n.&nbsp;</strong><br />La basura marina es un problema mundial, y la gente muestra preocupaci&oacute;n (Eastman <em>et al. </em>2013, Hartley <em>et al.</em> 2018). Por lo tanto, es importante conocer las opiniones de la gente local.&nbsp;<br /><br />La basura marina tambi&eacute;n puede generar mucho impacto en los organismos marinos, provocado por ingesti&oacute;n o enredo (Gregory, 2009). Aparte de estos impactos muy notorios, se han encontrado muchos organismos creciendo sobre la basura flotante; estos organismos podr&iacute;an ser transportados a diferentes costas por las corrientes y de esta forma invadir nuevos h&aacute;bitats (<em>Rech et al.</em> 2018). Conocer estos impactos es importante porque ayudar&aacute; a evaluar los riesgos de la basura marina.<br /><br />Playa Grande de Santa Cruz es una comunidad tur&iacute;stica ubicada en la cercan&iacute;a del Parque Nacional Marino Las Baulas, en la provincia de Guanacaste, Costa Rica. Este sitio se encuentra dentro de la Bah&iacute;a de Tamarindo, un &aacute;rea protegida de anidaci&oacute;n importante para especies en riesgo cr&iacute;tico de extinci&oacute;n como las tortugas baula del Pac&iacute;fico Tropical Oriental (<em>Dermochelys</em> <em>coriacea</em>)(Santidri&aacute;n <em>et al.</em> 2007), de otras tortugas marinas y aves con poblaciones reducidas (SINAC, 2016).<br /><br />Entre las amenazas para conservaci&oacute;n de &eacute;stas y de otras especies se encuentra la contaminaci&oacute;n por residuos s&oacute;lidos debido a actividades tur&iacute;sticas no planificadas que se desarrollan en la zona y el mal manejo de los desechos s&oacute;lidos (SINAC, 2018).&nbsp;<br /><br />Algunos pobladores locales, e incluso visitantes, han realizado diferentes esfuerzos para reducir el grado de contaminaci&oacute;n por desechos s&oacute;lidos en esta playa. No obstante, se desconoce con precisi&oacute;n la procedencia de la basura y qu&eacute; mecanismos son necesarios para erradicar, o al menos, reducir este problema.<br /><br />Dado este contexto y la escasa informaci&oacute;n preexistente, en este estudio se considera el an&aacute;lisis de las siguientes preguntas de investigaci&oacute;n (1) &iquest;Qu&eacute; percepci&oacute;n tienen las personas de esta localidad sobre el problema de las basuras marinas?, y (2) &iquest;Qu&eacute; interacciones bi&oacute;ticas y qu&eacute; organismos son m&aacute;s frecuentes en la basura de esta playa?<br /><br />Para responder estas preguntas, en este proyecto se realizan dos investigaciones colaborativas: (1) Una encuesta a las personas de la localidad, y (2) un muestreo en la playa local, identificando los organismos que interaccionan con la basura.&nbsp;</div>  <div class="paragraph"><strong>2. Metodolog&iacute;a</strong><br /><strong>2.1. Lugar del colegio y de las investigaciones</strong><br />Los colaboradores fueron estudiantes de la Escuela de Playa Grande, un centro educativo unidocente de etapa b&aacute;sica o primaria, con 11 estudiantes cuyas edades rondan de los 7 a los 12 a&ntilde;os.<br /><br />&#8203;Para ello, los estudiantes realizaron una encuesta para un an&aacute;lisis de percepci&oacute;n sobre la contaminaci&oacute;n por basura marina y, por otra parte, una evaluaci&oacute;n de las interacciones bi&oacute;ticas presentes sobre la basura, que nos dieran pistas sobre el origen de estos desechos.<br /><br />La investigaci&oacute;n colaborativa se realiz&oacute; en uno de los tres principales accesos en playa Grande, Parque Nacional Marino Las Baulas. Esta es una zona de alta atracci&oacute;n tur&iacute;stica en un ambiente de car&aacute;cter rural (Ver Figura 1).</div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0px;margin-right:10px;text-align:center"> <a> <img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/editor/img-20180504-142809-effects.jpg?1591821161" alt="Picture" style="width:auto;max-width:100%" /> </a> <div style="display:block;font-size:90%">Figura 1.

Ellos fueron asistidos por los otros escolares de menor edad.<br /><br />&#8203;Debido a que solo 3 de los 11 estudiantes se encuentran en la edad adecuada para leer y rellenar el formulario, el n&uacute;mero de encuestas totales es muy bajo.</div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0px;margin-right:0px;text-align:center"> <a> <img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/published/img-20190827-090517.jpg?1591824606" alt="Picture" style="width:448;max-width:100%" /> </a> <div style="display:block;font-size:90%">Figura 2.

No obstante, los encuestados mencionaron, en menor medida, que limpiezas constantes, colocaci&oacute;n de m&aacute;s basureros e incentivos o regulaciones a empresas puede ayudar a solucionar este problema.<br /><br /><strong>3.2. Interacciones Bi&oacute;ticas</strong><br />La gran mayor&iacute;a de los objetos de basura recolectada en playa Grande se compone principalmente de pl&aacute;stico, pues 137 piezas de las 153 recolectadas, son de este material. En mucha menor cantidad se encuentra madera procesada, telas, papel o cart&oacute;n, metal y restos org&aacute;nicos. Aun as&iacute;, &eacute;stos representan tan solo el 9% de los materiales recolectados.<br /><br />Del total de objetos recolectados (n = 153 objetos totales) &uacute;nicamente un 25% (n = 39 objetos) ten&iacute;a alguna interacci&oacute;n bi&oacute;tica (Tabla 1). Las interacciones m&aacute;s comunes corresponden a &iacute;tems con adherencia y mordeduras.&nbsp;<br /><br />Tabla 1 Cantidad de &iacute;tems de basura con diferentes tipos de interacciones bi&oacute;ticas.</div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:0px;padding-bottom:0px;margin-left:0px;margin-right:0px;text-align:center"> <a> <img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/published/tabla1.png?1591825592" alt="Picture" style="width:auto;max-width:100%" /> </a> <div style="display:block;font-size:90%"></div> </div></div>  <div class="paragraph">De los 39 objetos recolectados con alguna interacci&oacute;n bi&oacute;tica, se analiz&oacute; una muestra de 6 objetos de basura que presentan interacci&oacute;n bi&oacute;tica por adherencia.

Participaci&oacute;n y aprendizajes de los alumnos&nbsp;<br /></strong>Al ser el centro educativo una escuela unidocente, se presenta el reto de captar la atenci&oacute;n y participaci&oacute;n de todos los estudiantes para el estudio de las interacciones bi&oacute;ticas de acuerdo a su rango etario. Aun as&iacute;, el libro &ldquo;<a href="https://educacion.mma.gob.cl/wp-content/uploads/2019/10/La-Hermandad-de-Las-Tortugas.pdf" target="_blank">La Hermandad de las Tortugas</a>&rdquo; despert&oacute; el inter&eacute;s de todos por conocer m&aacute;s sobre el problema de la contaminaci&oacute;n por desechos s&oacute;lidos en playa Grande y su relaci&oacute;n con los ecosistemas marinos, sobre todo su interacci&oacute;n con las tortugas marinas.<br /><br />Se realiz&oacute; una peque&ntilde;a evaluaci&oacute;n de los intereses y participaci&oacute;n de los ni&ntilde;os en estas investigaciones. Es de gran inter&eacute;s en la mayor&iacute;a de los ni&ntilde;os (n = 10) aprender sobre la problem&aacute;tica de la contaminaci&oacute;n por desechos s&oacute;lidos con el objetivo de ayudar al medio ambiente, seg&uacute;n mencionaron en una encuesta de evaluaci&oacute;n. De igual manera, la totalidad de los ni&ntilde;os (n = 11) se mostraron interesados por la identificaci&oacute;n de las especies presentes en los desechos donde encontraron interacciones para conocer la procedencia de la basura.<br></div>  <div class="wsite-youtube" style="margin-bottom:10px;margin-top:10px;"><div class="wsite-youtube-wrapper wsite-youtube-size-xl wsite-youtube-align-center"> <div class="wsite-youtube-container">  <iframe src="//www.youtube.com/embed/qXioDHI0H0E?wmode=opaque" frameborder="0" allowfullscreen></iframe> </div> </div></div>  <div class="paragraph"><strong>4. Discusi&oacute;n</strong><br />Con las muestras analizadas, los resultados de ambas investigaciones indican que hay evidencia de un problema por contaminaci&oacute;n por desechos s&oacute;lidos en la playa en estudio, principalmente por pl&aacute;sticos. Las personas encuestadas consideran que este problema se debe principalmente por personas que visitan esta playa o residen cerca de &eacute;l. Esta percepci&oacute;n coincide con el hecho que la mayor cantidad de desechos s&oacute;lidos encontrados en las playas no muestran interacciones con especies marinas, lo que sugiere que no llegaron a la playa a trav&eacute;s de las corrientes marinas.<br /><br />Por lo tanto, es importante considerar que las mismas personas encuestadas recomiendan que acciones de educaci&oacute;n ambiental es la mejor opci&oacute;n para solucionar el problema de acumulaci&oacute;n de basura en esta playa.<br /><br /><strong>4.1. Encuestas</strong><br />En estudios realizados en Chile (Eastman et al, 2018) y Brasil (Santos et al, 2005), las personas encuestadas consideraron que acciones educativas son las mejores opciones para solucionar el problema de la basura marina. Esto coincide con lo obtenido en nuestras encuestas, ya que se obtuvo que un gran n&uacute;mero de personas respondi&oacute; que la educaci&oacute;n ambiental es la mejor opci&oacute;n para solucionar el problema de la contaminaci&oacute;n de las playas por desechos s&oacute;lidos.&nbsp;<br /><br />Entre otras soluciones, los encuestados sugieren que actividades de limpieza de playa y mayor cantidad de dep&oacute;sitos de basura pueden contribuir a solucionar el problema. Aun as&iacute;, a diferencia de Chile y Brasil, los encuestados en Playa Grande no mencionan las multas como una medida pr&aacute;ctica para reducir la contaminaci&oacute;n en las playas de la localidad, a pesar que ya existe legislaci&oacute;n para ello (Ley 6084, art. 8, inciso 11; Ley 8839, art. 50, inciso b).<br /><br />Una debilidad de este estudio es que en la Escuela de Playa Grande la cantidad de estudiantes es reducido y por ende el tama&ntilde;o muestral bajo, tanto para las encuestas como para las interacciones. Los resultados deben tomarse con cautela y es oportunidad para pr&oacute;ximas investigaciones incluir mayor n&uacute;mero de encuestas y an&aacute;lisis de muestras de basura con el objetivo de esclarecer mejor el problema.<br /><br /><strong>4.2. Interacciones bi&oacute;ticas&nbsp;</strong><br />En la playa de estudio se encontr&oacute; una mayor proporci&oacute;n &iacute;tems de material pl&aacute;stico, lo que es muy similar al estudio de Rech et al. (2018) donde encontraron alrededor de un 75% de pl&aacute;stico en sus muestras. Sin embargo, en relaci&oacute;n a las interacciones bi&oacute;ticas difieren los resultados, ya que en playa Grande se obtuvieron pocos objetos con interacciones bi&oacute;ticas. Entre los organismos que se encontraron en las muestras de playa Grande, dominaron los briozoos, muy diferente al estudio de Rech et al. en el cual predominaron los artr&oacute;podos.<br /><br /><strong>5. Conclusi&oacute;n y recomendaci&oacute;n</strong><br />La realizaci&oacute;n de la encuesta fue un &eacute;xito por parte de los tres estudiantes y la colaboraci&oacute;n de los dem&aacute;s asistentes. Los encuestados presentes estaban dispuestos a responder las preguntas hechas por los alumnos. Dado esto, nuestras investigaciones sugieren que la gente est&aacute; preocupada del problema de la basura.<br /><br />La presencia de interacciones de adherencia y mordidas nos da informaci&oacute;n sobre el tiempo que pas&oacute; esta basura en el medio marino. El estudio de las interacciones sugiere que la procedencia de la basura es mayormente local ante la escasa presencia de biota.&nbsp;<br /><br />Por lo tanto, ambos estudios sugieren que una estrategia de educaci&oacute;n ambiental en la localidad es herramienta importante para combatir este problema. No obstante, se requiere mayor informaci&oacute;n cient&iacute;fica para este lugar con el fin de sensibilizar mayormente a la poblaci&oacute;n local. De Igual manera se requieren an&aacute;lisis de vectores para conocer mejor la procedencia de los desechos y desarrollar estrategias m&aacute;s puntuales.<br /><br /><strong>6.

On this occasion, last Friday, March 3, the XV edition of the Leatherback Turtle Festival (&ldquo;Festival de las Tortugas Baulas&rdquo; in Spanish) was held to commemorate the nesting of the sea turtles that have come to nest this season at the beaches of the Las Baulas&nbsp;National Marine Park. This festival had as its central topic: the biological corridors, connecting life and well-being.<br /><br />&#8203;In this edition, The Leatherback Trust reiterates its commitment and support to the Las Baulas National Marine Park. Together, we let the kids have the opportunity to play, learn and know each other with the participating schools the day before the festival. The children not only learned about turtles and marine corridors, but also about the importance of working collectively to pursue a common goal.</div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0;margin-right:0;text-align:center"> <a> <img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/tlt1_orig.jpg" alt="Picture" style="width:auto;max-width:100%" /> </a> <div style="display:block;font-size:90%"></div> </div></div>  <div class="paragraph"><span style="color:rgb(77, 85, 94)">Once the Festival was over, we opened the opportunity for the attendees to participate in a drawing contest whose prizes were backpacks with a kit of school supplies, and to everyone a gift.

In this month, different beach clean-up days were also held in Tamarindo Bay, resulting in the extraction of a large amount of plastic, especially products that are for single use and others that can even be reused or recycled.<br /><br />&#8203;With the support of different government institutions, organizations, neighbors, tourists and volunteers, this November we collected around 485 pounds (220 kilograms) of waste in Playa Grande and Playa Ventanas in several cleaning campaigns. Around 15% of the material collected could have been reused or recycled before they reached the sea, since this percentage represents plastic bottles, aluminum cans and glass containers that, due to their conditions, had to be discarded in their entirety.</div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0;margin-right:0;text-align:center"> <a> <img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/plastic-baulas_orig.png" alt="Picture" style="width:auto;max-width:100%" /> </a> <div style="display:block;font-size:90%"></div> </div></div>  <div class="paragraph">There are several efforts for an effective management of recyclable materials in the Bay of Tamarindo and it is important to highlight the work of the ADI Tamarindo (Asociaci&oacute;n de Desarrollo Integral de Tamarindo), and the Municipality of Santa Cruz with the collection campaign of recyclable material the first Tuesday of each month (<a href="https://www.facebook.com/ADIPlayaTamarindo/photos/a.380218075475989.1073741829.164737377024061/853329458164846/?type=3&amp;theater" target="_blank">more information here</a>). While on the other side of the Tamarindo Estuary, there is the work of the Solid Waste Management Program of the Las Baulas National Marine Park, where they receive and separate PET plastics, aluminum and glass cans.<br /><br />Despite this, the challenge in the bay is even greater. A lot of microplastic still remains on the beaches and now its presence is almost unnoticed. Hence the importance of carrying out or helping campaigns that seek to reduce plastic pollution, such as the No Straw Challenge, Sin Pajilla Por Favor that was started in Playa Grande, or others that have been emerging at different scales, either at a more regional or even national, such as the website&nbsp;<a href="http://www.zonalibredeplastico.org/" target="_blank">zonalibredeplastico.org</a>.<br /><br />The challenge of eliminating the discarded plastic on the beaches is a task that involves the participation of all, and the decision lies in the use and disposition that is given. Support local initiatives, manage your own initiative, organize with your neighbors and enforce that right to live in a healthy and ecologically balanced environment.<br /><br /><em>&#8203;* Special thanks to Nadia Tarlow, Las Baulas National Marine Park, the Tamarindo Development Association, the Tourist Police, neighbors and businessmen of Playa Grande and Tamarindo who have given their support.

Leatherbacks typically nest under the cover of darkness, but once in a rare while our team out conducting a morning survey happens upon a sea turtle that is up late enough she may still be on the beach as the sun rises. Since light disrupts nesting sea turtles, photographs may not be taken of nesting sea turtles at night, but sea turtles that are up under the bright morning light are free game to take photos of respectfully and without the use of flash. Our project has been making large efforts to be at the lead of exciting new research methods conducted with drones, and I was lucky enough to remember to bring one out with me so you could witness this exciting event of a leatherback returning to the sea after completing her nesting process. What is so very exciting about using the drone is that we are able to not only see how the leatherback moves on land, but how graceful she is once she&rsquo;s in the water clear of the shore.<br /><br />Parque Nacional Marino Las Baulas remains the largest nesting location for the Eastern Pacific leatherback, a population that has declined by more than 98% since 1990. Organizations such as The Leatherback Trust, MINAE (Ministerio Ambiente y Energ&iacute;a, or Ministry of Environment and Energy)&rsquo;s rangers, schools and universities, and even local restaurants are working tirelessly to prevent further decline of this population. Threats to these animals include climate change - where increased temperatures can cause nest mortality, pollution with plastics &ndash; which get lodged in digestive systems and nasal passages causing mortality, fisheries &ndash; where turtles are accidentally caught on long lines or in shrimp trawling traps and drown, known as bycatch, and habitat loss &ndash; leaving our girls with no place to lay their eggs.&nbsp;Fortunately there are&nbsp;<span style="font-weight:700">many</span>&nbsp;ways you can help save this species, and all other flora and fauna protected found in our national park.<br />&#8203;<br />Playa Grande, the largest of the beaches in Las Baulas National Park, is not only well known for surf breaks and stunning sunsets but also for visits from nesting turtles like critically endangered East Pacific leatherbacks.</div>  <div class="wsite-map"><iframe allowtransparency="true" frameborder="0" scrolling="no" style="width: 100%; height: 250px; margin-top: 10px; margin-bottom: 10px;" src="//www.weebly.com/weebly/apps/generateMap.php?map=google&elementid=901189601351808498&ineditor=0&control=3&width=auto&height=250px&overviewmap=0&scalecontrol=0&typecontrol=0&zoom=12&long=-85.84190519999999&lat=10.323483&domain=www&point=0&align=1&reseller=false"></iframe></div>  <div class="paragraph" style="text-align:left;">Every year, during the leatherback nesting season (between October and March), leatherbacks come ashore to lay their eggs at night; up to 60 days later, the eggs hatch and the hatchlings start their race to the ocean. Black and olive ridley turtles also nest here, and portions of their nesting seasons overlap with the leatherback nesting season. &nbsp;<br /><br />There are seven different species of sea turtles in the world, and Playa Grande is regularly visited by the aforementioned three species. The leatherback turtle (<em>baula</em>&nbsp;in Spanish) can measure up to 130 &ndash; 190 cm (52 &ndash; 75 in) and weigh 250 &ndash; 500 kg (550 &ndash; 1100 lbs). Since leatherbacks exclusively feed on jellyfish species, it&rsquo;s incredible to think they can grow this large on jellyfish alone! East Pacific leatherbacks migrate from as far south as the waters off Chile and Peru, where they forage in the cold upwellings of the Humboldt current, to tropical waters offshore nesting beaches where they lay their eggs, such as here in Guanacaste province.<br /><br />The East Pacific Green turtle, also known as the black turtle (<em>negra</em>&nbsp;in Spanish), can measure approximately from 80-122 cm (32 &ndash; 48 inches) and weigh 65-204 kg (144 &ndash; 450 lbs). This turtle&rsquo;s main diet is sea grasses and algae, and occasionally jellyfish. They travel along the coast of Central America and venture as far south as the Gal&aacute;pagos Islands.<br /><br />The olive ridley (<em>lora</em>&nbsp;in Spanish) measures around 55 &ndash; 75 cm (22 &ndash; 30 inches) and weighs 36 &ndash; 45 kg (85 &ndash; 95 lbs). Olive ridleys are considered to be the most abundant sea turtles in the world, although the current global population is only 0.2% of the species&rsquo; historical abundance. Females often nest together in large aggregations, known as&nbsp;<em>arribadas</em>, which only occur on certain beaches, like the local Ostional. Scientists have recorded arribadas of up to 200,000 turtles at once. Olive ridleys forage along drift lines for crabs, jellyfish, clams, squid, snails and algae.<br /><br />Playa Grande, Playa Ventanas and Playa Langosta, are all part of Las Baulas National Park (Parque Marino Nacional Las Baulas). The Park protects the last mass-nesting beach for the East Pacific leatherback turtle, a population designated as critically endangered by the International Union for Conservation of Nature (IUCN). Park Rangers, local guides, members of local communities, and researchers are working hard to save these turtles from extinction, as well to protect the local wildlife and flora.<br /><br />Las Baulas National Park was created more than 20 years ago to protect the sea turtles and other ecosystems, including estuaries, wetlands, dry forests and the marine habitat extending 12 nautical miles offshore.<br />In the late 1980s, when The Leatherback Trust scientists began collecting standardized data on nesting turtles on Playa Grande and Playa Ventanas, they documented hundreds of turtles nesting on the beach each night during the nesting season. At that time, egg poachers had organized themselves in groups and divided up the beach to collect every last leatherback egg. &nbsp;Unfortunately, the result was the loss of an entire generation of East Pacific leatherbacks.<br /><br />The Leatherback Trust&rsquo;s founders, Dr. Jim Spotila and Dr. Frank Paladino, worked with Mario Boza to create The Leatherback Trust to stop egg poaching at Playa Grande and Playa Ventanas and their support helped lead to the creation of Las Baulas National Park. Our organization&rsquo;s scientists and volunteers continue to conduct monitoring activities at Playa Grande and Playa Ventanas, in communication with Park officials, and we are proud to say that today, there is virtually no poaching in Las Baulas National Park. Nevertheless, there are still other threats that compromise the survival of this species.<br /><br />For every 1,000 hatchlings, only one sea turtle reaches adulthood. Climate change, pollution, nest disturbance, fishing and habitat loss are now the main threats to leatherbacks and other sea turtles. Increases in sand temperature due to climate change can kill hatchlings in the nest before they fully develop. Around 30&deg;C the mortality starts to increase and by 33&deg;C the mortality rate is close to 100%.<br /><br />Plastic, lights, and water pollution can compromise the survival of sea turtles. Turtles can confuse plastic bags, straws, or utensils with food. Plastics can get stuck in their digestive systems or lodged in their nasal passageways, as our scientists have seen. Light pollution disorients the hatchlings trying to reach the ocean, making them more vulnerable to predation or dehydration; adult turtles trying to find their way to the beach to nest are also disoriented by&nbsp;coastal lighting. Water pollution from leaky septic tanks, agricultural runoff, oil spills, or even runoff of oily residue from streets can lead to respiratory inflammation, gastrointestinal ulceration, organ damage and reproductive failure.<br /><br />Longline fisheries for tuna, swordfish, and mahi-mahi, as well as shrimp trawling present one of the most serious threats to sea turtles in the ocean. Although turtles are not targeted by these fisheries, they get stuck in weighted nets used by trawlers or entangled on the miles of lines with baited hooks set by longliners, becoming &ldquo;bycatch&rdquo; and often drowning when they are unable to surface for air. Costa Rica has taken action to improve fisheries practices, for example by phasing out bottom trawling for shrimp, but consumers must not only demand strong fishing regulations to protect sea turtles but also reduce demand for unsustainably captured fish.<br /><br />Finally, habitat loss at nesting beaches can leave sea turtles with no place to nest. The shade beachfront trees produce can help cool nests, which impacts the gender of hatchlings. Loss of coastal vegetation also increases compaction of sand, preventing turtles from digging, and erosion, exposing nests to danger.<br /><br />Las Baulas National Park, The Leatherback Trust and other organizations, companies, and neighbors are working together to help save sea turtles. How can you help? Here some tips from The Leatherback Trust&rsquo;s Outreach Manager, Christian D&iacute;az Chuquisengo:<br /><br /><ol style="color:rgb(77, 85, 94)"><li><span style="font-weight:700">Climate change:&nbsp;</span>when using the A/C, use weatherstripping in windows and doors, to keep the cool air from escaping and reducing energy use. Turn off all your electronic appliances if you are leaving your home for several months. Replace incandescent light bulbs with LEDs and maximize use of natural light in your housing design. Ride your bike or walk when traveling short distances. Plant a tree near your house to increase shade and further reduce your electric bill. Support policies that reduce carbon emissions to mitigate climate change.<br />&#8203;</li><li><span style="font-weight:700">Pollution:</span>&nbsp;if you live in a beachfront or oceanview building, use red filters or curtains at night in rooms facing the beach, to avoid disorienting turtles and other animals with artificial light. If you are visiting a hotel or renting a house, inform the owners about how to protect turtles from light pollution. Help us recover dark skies: fewer lights mean more stars!&nbsp;<br /><br />Never forget the 3 Rs: Reduce, Reuse and Recycle.&nbsp;Tamarindo Development Association (ADI) organizes a recycling campaign the first Tuesday of each month. In Playa Grande, the National Park office collects aluminum beverage cans, plastic bottles, and glass. In other areas of Santa Cruz, the Municipality&nbsp;has a special truck named&nbsp;<em>SE-PA-RE</em>&nbsp;that collects recyclables.<br /><br />Add another R by Refusing straws, bags, disposable utensils, and other single-use plastics. Join a local plastic reduction campaign or start your own! The No Straw Challenge (<em>Sin Pajilla Por Favor</em>&nbsp;in Spanish), created by 12 year-old Max Machum in Playa Grande, encourages businesses and individuals to reduce use of plastic straws by providing them only upon request or substituting with&nbsp;biodegradable straws. Many businesses in Tamarindo, Playa Grande, and Playa Flamingo are participating. Now it&rsquo;s your turn!<br /><br /></li><li><span style="font-weight:700">Nest disturbance:</span>&nbsp;when you visit Las Baulas National Park beaches, remember there is a chance there could be a nest in the sand right under your feet! Don&rsquo;t put sticks or umbrellas in the sand above the high tide line. Bring a towel and find a place to sit between the ocean and the high tide line.&nbsp;Leave your dogs and other pets at home. Dogs can dig up the nests or dig near them, exposing the eggs to predators or interfering with hatchling development. If you visit unprotected nesting beaches outside the Park with your dog, use a leash.<br /><br /></li><li><span style="font-weight:700">Fishing:</span>&nbsp;support artisanal fishermen that use responsible fishing methods, such as pole fishing, trolling, or handlining. Educate your friends about sustainable fishing practices. Beware the vague term &ldquo;line-caught fish&rdquo;, which is often used to make longline fishing sound better.&nbsp;Eat low on the food chain and buy seafood from sellers that are committed to marine sustainability, respect fishing bans, or buy certified seafood. When you visit a restaurant, ask your waiter information about seafood and encourage businesses to buy from sustainable distributors or local artisanal fishermen using responsible fishing methods.<br /><br /></li><li><span style="font-weight:700">Habitat loss:</span>&nbsp;if you are building or buying a house, make sure it is set back from the beach. Don&rsquo;t buy properties within parks and adhere to restrictions on construction and resource use in parks, protected areas, and buffer zones. Minimize water use in landscaping. Plant native trees for shade to provide habitat for local species, prevent erosion, and minimize light and sound pollution on the beach.<br />&#8203;</li></ol>When each of us begins to take action to protect the environment, the changes add up to benefit all living things, including critically endangered East Pacific leatherbacks.&nbsp;Let&rsquo;s all remember: their future is in our hands.<br /></div>  <div><div class="wsite-multicol"><div class="wsite-multicol-table-wrap" style="margin:0 -15px;">	<table class="wsite-multicol-table">		<tbody class="wsite-multicol-tbody">			<tr class="wsite-multicol-tr">				<td class="wsite-multicol-col" style="width:50%; padding:0 15px;">											<div id="589769176113464366"><div><style type="text/css">	#element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6 .callout-box-wrapper {  padding: 20px 0px;  word-wrap: break-word;}#element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6 .callout-box--standard {  border: 1px solid #E0E0E0;  background: #FAFAFA;  padding: 20px 20px;}#element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6 .callout-box--material {  border: 1px solid #E0E0E0;  background: #FAFAFA;  padding: 20px 20px;  box-shadow: 0 0 20px rgba(0,0,0,0.15);}#element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6 .callout-base {  border: 1px solid #E0E0E0;  background: #FAFAFA;  padding: 20px 20px;}#element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6 .material {  box-shadow: 0 0 20px rgba(0,0,0,0.15);}</style><div id="element-d73dc83a-f6fb-407b-a66b-2e4d2801dcd6" data-platform-element-id="694046499467037623-1.2.6" class="platform-element-contents">	<div class="callout-box-wrapper">	<div class="callout-box--standard">	    <div class="element-content">	        <div style="width: auto"><div></div><div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0;margin-right:0;text-align:center"><a><img src="https://www.sosgrande.org/uploads/1/1/6/6/11667209/jenell-black_orig.jpg" alt="Picture" style="width:auto;max-width:100%" /></a><div style="display:block;font-size:90%"></div></div></div><div class="paragraph"><strong><em>Jenell Black</em>&nbsp;</strong><em style="color:rgb(51, 51, 51)">is Field Manager for The Leatherback Trust.&nbsp;Jenell leads the sea turtle monitoring project at the Goldring-Gund Marine Biology Station.

The Costa Rican regulations prohibit entry of pets into national parks. Park officials ask visitors and nearby residents to ensure pets remain at home, promote awareness of national park rules through informational signage, and retain the power to enforce park regulations through legal action.<br /><br />National parks bear the most stringent regulations of all protected areas, designed to mitigate any threats to wildlife or ecosystems within the park. The National Park Law (article 8, section 9) prohibits the introduction of non-native species to parks, including dogs and cats. Las Baulas National Park&rsquo;s Regulation on Public Use (D.E. 36918-MINAE, article 16, subsection e) also proscribes entry of pets.<br /><br />This Park protects habitat essential to the life cycle of critically endangered East Pacific leatherbacks (Dermochelys coriacea), as well as vulnerable olive ridley (Lepidochelys olivacea) and endangered East Pacific green turtles (Chelonia mydas). These sea turtles lay their eggs on the beaches within Las Baulas National Park and, months later, their hatchlings race over the sand to the shoreline.<br /><br />Degradation or destruction of critical habitat, climate change and fisheries all pose threats to sea turtles at various stages of their life histories. Apart from conservation of important nesting beaches, protecting nests from dogs is an essential first step to ensure the survival of the species from embryonic development to hatching and each hatchling&rsquo;s race to the sea.<br /></div>  <div><div style="height:20px;overflow:hidden"></div> <div id='345054880186751966-slideshow'></div> <div style="height:20px;overflow:hidden"></div></div>  <div class="paragraph">Dr. Nathan Robinson, The Leatherback Trust&rsquo;s Field Director in Playa Grande, corroborated findings presented in a recent paper indicating that&nbsp;<a href="http://onlinelibrary.wiley.com/doi/10.1111/acv.12143/full">domestic dogs may pose a higher risk</a>&nbsp;to sea turtle nests than feral dogs, since they are driven to dig up nests by curiosity rather than hunger.

Keeping pets secured within the home rather than roaming the neighborhood will help local wildlife. When taking &nbsp;your pet out for a walk, have a good time in places appropriate for them, but plan to leave pets at home when you visit Las Baulas National Park. If &nbsp;you visit another nesting beach that is not within a protected area, remain aware of your dog&rsquo;s activities. Watch out for any digging and make sure your pet does not try to &ldquo;play with&rdquo; hatchlings or other wildlife. By working together in these ways, we can all save sea turtles.<br /><span></span></div> <hr style="width:100%;clear:both;visibility:hidden;"></hr>]]></content:encoded></item></channel></rss>
