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.

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.

[caption id="attachment_4691" align="alignleft" width="225"] A recently planted Zapote Olimpico seedling.[/caption] During this past July, while walking through the Cerro Osa forest, Agustín Mendoza, one of the most charismatic members of Osa Conservation’s conservation and land management team, heard sounds and a great deal of activity at the top of the canopy. As he came closer to the site, he realized that the clamor was coming exclusively from a Zapote tree (Pauteria Sp). This tree was full of juicy fruits characterized by an exquisite orange color and a sweet scent that invaded the monotonous serenity of the forest. In the top of the tree he found a complete troop of spider monkeys that jumped from branch to branch, 35 meters in the air, taking advantage of the sudden abundance of this unusual feast.

By Katie Mascovich [caption id="attachment_4646" align="alignleft" width="300"] The green sea turtle's wounds are healing naturally[/caption] No two night patrols on the Osa are the same, but they usually have the same rhythm. Every now and then, however, something unexpected happens that makes the whole night worthwhile. On November 3, I had one of these experiences. But to fully understand it, I have to tell you about the patrol I had on October 21. That night I was patrolling Pejeperro Beach with Emily, another Research Field Assistant. It was one of those long nights where we knew we would not be back to the station and in our beds until dawn.

While the Osa Peninsula, rich with biodiversity and sheer beauty, is a wonderful place to kick back and relax, there are numerous opportunities for visitors to catch a glimpse of some of the world's most fascinating reptiles. Some of which, like the Terciopelo, can be especially hard (and dangerous) to spot. The Terciopelo is a beautiful dark grey, brown or olive green snake, with a dorsal pattern of triangular designs on both sides of its body, resembling a letter 'X' visible from above. It’s a large snake that can grow up to 250 cm (over eight feet!) in length, although the average adult is between 140 and 180 cm (4.6 to 5.9 ft) long. The females are much longer than the males. It principally eats small mammals and birds. The species is viviparous, which means that the embryos grow inside of the mother and are born fully formed. Furthermore, the snake is very fruitful; it can give birth to up to 90 offspring. This high fertility explains in part why the Terciopelo is one of the most abundant snakes in Costa Rica.

[caption id="attachment_4566" align="alignleft" width="300"] Mogos Islands mark the highest waters of Golfo Dulce.[/caption] By Brooke Bessesen While Jorge and I both loved working on the water, the results of our research brought the greatest rewards. Golfo Dulce is a true bio-gem—one of Costa Rica’s preeminent riches. Several hundred Green sea turtles, critically endangered Hawksbill sea turtles, Olive Ridley sea turtles and (reportedly) Pacific Leatherback sea turtles, rest, feed, mate and nest in the gulf. A rare xanthic colony of pelagic sea snakes resides around the inner basin. Both Northern and Southern Hemisphere Humpback whales enter the inlet to give birth and possibly provide sanctuary for young calves. Whale sharks aggregate in Golfo Dulce. Resident dolphins and other toothed cetaceans breed and raise offspring. Scalloped hammerhead sharks are born there and needlefish spawn. What a remarkably vibrant bionetwork!

[caption id="attachment_4531" align="alignleft" width="300"] Panelists discuss the environmental impacts of the proposed marina project at a community forum[/caption] By Andrea Johnson For the last two weekends, hundreds of people from Puerto Jimenez and surrounding towns have crowded together into small hot rooms for hours on end to engage in heated discussions about a very important current affair that is getting people talking in the Osa Peninsula. And there's not a soccer ball in sight. The events are a series of community forums revolving around a proposed development project. Five hour long public forums; democracy can be painful. The project in question is a marina and mega resort-style complex that the owners of Crocodile Bay Resort, an all-inclusive sport-fishing resort in town, want to build out into the waters off the town’s public beach. This would be the first marina to be built on the Osa Peninsula or in the Golfo Dulce, a globally unique marine ecosystem.

Along with a few other ASCONA volunteers, Daniel, as he prefers to be called, is part of an extremely passionate group of activists protesting an American business-owner's proposal for a large marina development project on the Gulfo Dulce, a proposal met with considerable opposition among Osa residents and various conservationists on and around the peninsula.
