By Pilar Bernal Mientras en este mes de febrero los estudiantes se preparan para iniciar su periodo escolar, en el Programa de Educación Ambiental nos estamos preparando con los materiales, actividades y cronogramas  para iniciar con los talleres a impartir a lo largo del año en 15 centros educativos de la Península de Osa. Los temas del currículo de educación ambiental para este año son: ecosistemas terrestres y marinos, deforestación y cambio climático, y manejo de desechos. Así mismo, todos los años en el mes de mayo Conservación Osa coordina...

By Juan Carlos Cruz Jaguars are very charismatic creatures, and for indigenous people and ancient civilizations, were considered symbols of power, majesty and wisdom. While that symbolism still holds true, we now also recognize their intrinsic value for maintaining biodiversity in the forests. They are on the top of the food chain and therefore the health of their population affects all subsequent levels. In the absence of Jaguars, breakdowns occur in the ecosystem such as increases of populations of herbivores, decreases in population of some species of plants (eaten by herbivores) and loss of other species of birds, insects and reptiles that depend on those plants. The presence of Jaguars in a region is an indicator of the health and integrity of the forest since they are the most sensitive species of all large cats to exploitation and habitat alteration. Accordingly, they are also known as “health indicator species.”

In addition to celebrating a great year in 2012, Osa Conservation recently honored two staff members as outstanding employees of the year. If you have visited us here in Osa, these are most likely familiar faces. Thanks Agustín and Manuel for all of your hard work and for being such integral and exemplary members of the Osa Conservation team.  Agustín Mendoza Augustín has been working with OC for five years on our land stewardship and maintenance team but has lived in Osa for 38. He grew up in Cerro Arbolito a remote...

As some of you may know from following our Facebook and Twitter posts, Manuel Sanchez Mendoza, our Research Assistant and Sea Turtle Conservation Program Field Coordinator, has one heck of a talented eye for photographing wildlife. As an Osa native, born and raised in the peninsula, Manuel has always been fascinated with wildlife, and although he has no formal training in photography, we like to think he has a natural-born knack for it. The past few weeks in particular have been very successful for Manuel and his camera, and we at Osa Conservation are excited to share his sightings with you! All of these photos were taken at or around our Piro Biological Center.

In order to create public access stations for environmental education purposes, Osa Conservation recently built and inaugurated a 2.5-mile interpretive trail. In this easy journey, adventurers will find 23 stations labeled to help them understand and interpret the ecosystems, species and ecological associations that cross the path, which is a representation of the biological richness of the Osa Peninsula.

Con el objetivo de crear un acceso público a las estaciones con fines de educación ambiental, se construyó un sendero interpretativo de 2.5 km. Este sendero es de fácil recorrido, en donde el usuario encontrará 23 estaciones rotuladas que le ayudarán a comprender e interpretar los ecosistemas, especies y asociaciones ecológicas por las que atraviesa el sendero, que son una representación de la riqueza biológica de la Península de Osa.

Las Lapas Rojas (Ara macao), son una especie en grave peligro de extinción. En Costa Rica existen solamente dos poblaciones viables de Lapas Rojas, la más grande de las cuales se encuentra en la Península de Osa. Esta población se estima entre 800 y 1200 individuos (Dear et al 2010). Dicha población fue eliminada casi por completo debido a la tala indiscriminada de arboles para madera y agricultura, la casería para consumo, y  el comercio ilegal de estas aves como mascota. Durante las ultimas dos décadas, la tala comercial y la cacería de aves ha disminuido significativamente, y la población de Lapas de la Península de Osa se ha incrementado rápidamente. Sin embargo, la perdida de cavidades naturales usadas como nidos por estos animales ha limitado grandemente la recuperación de sus poblaciones. Un estudio realizado en los últimos anos recomienda usar un sistema de conservación de largo plazo que combine educación ambiental en las escuelas locales, involucramiento de las comunidades, y penalidades mas estrictas para los cazadores y destructores del hábitat de la Lapa Roja (Guittar et al 2008).

The Scarlet Macaw (Ara macao) is a species in danger of extinction. In Costa Rica, there are only two healthy populations of scarlet macaws, the largest of which is located on the Osa Peninsula. This population is estimated to be between 800 and 1200 individuals (Dear et al 2010). This population was almost completely eliminated due to the illegal removal of trees for timber and agriculture, hunting for food, and illegal trade of Macaws as pets. During the last two decades, commercial logging and hunting of birds has decreased significantly, and the population of Macaws of the Osa Peninsula has increased rapidly. However, the loss of natural cavities in the trees used as nests for these animals has greatly limited the recovery of their populations. A study in recent years recommended long-term conservation that combines environmental education in local schools, community involvement, and stricter penalties for hunters and the Lapa Roja habitat destroyers (Guittar et al 2008).

By Carolina Herrera, NRDC Wondering where that brightly colored songbird that visited your yard during the summer disappeared to when the temperature dropped? Many songbirds and other migratory birds spend the cooler months in Latin America’s tropical rainforests, so preserving their winter habitat is essential to their survival. That’s one reason why NRDC partnered with the group Osa Conservation to help Revive a Rainforest on Costa Rica’s Osa Peninsula, one of the most biodiverse places on Earth. With the support of our members we’ve been helping to restore 50 acres of degraded tropical rainforest by planting carefully selected native tree species. Six hundred and fifty species of birds make North America their home and breeding ground. While some of these birds are permanent residents many are migratory, with migration paths varying from short, medium to long. Approximately 350 species breed in the US and Canada and then winter all the way in Latin America and the Caribbean where they need to find sufficient food and safe nesting locations. The Yellow Warbler, Tennessee Warbler, and the Canada Warbler are just three of the many species that journey long distances during their seasonal migrations to Costa Rica’s Osa Peninsula.

[caption id="attachment_4712" align="alignleft" width="300"] RFA's and interns pose for a photo at our annual Sea Turtle festival this past September[/caption] November is the peak of the rainy season here in Osa, an ideal time for staying in, curling up with a good book and listening to the sheets of rain pelt the tin roof. Not so for the OC staff and our brave visitors and volunteers who have been working rain and shine to help us with various conservation projects! This month we're finishing up the Sea Turtle season and will be saying our goodbyes to our amazing Research Field Assistants that have made the program possible. Sai, Emily, Bre and Katie, we are incredibly grateful for your dedication and contribution this season. Thank you also to Katharine, Jamie and Alyssa, our field assistants who joined us for the first half of the season and all of our volunteers.
