Corcovado National Park

La mitad de las áreas silvestres actuales, se encuentran en los países tropicales y se crearon después de 1970. Sin embargo, las actividades humanas han alterado gravemente las áreas silvestres protegidas tropicales y el 75% de las áreas silvestres de América Latina carece de protección efectiva, planes largo plazo y recursos económicos para garantizar una gestión eficaz. Una causa parcial es que las áreas protegidas fueron concebidas utilizando el modelo conservacionista de EE.UU. de apartar hábitats no alterados “para el disfrute de las generaciones actuales y futuras”, sin tomar en cuenta la población local. El objetivo de este trabajo es documentar la ecología histórica de la creación del Parque Nacional Corcovado en la Península de Osa, Costa Rica. Este artículo presenta una reconstrucción histórica de cómo se creó el área, los actores involucrados y sus interacciones, en busca de una mejor planificación nacional de conservación. Considerando su tamaño, el parque es uno de los sistemas ecológicos más diversos del mundo, pero está expuesto a problemas relacionados con la extracción de madera, fauna y oro. La comunicación abierta y la búsqueda de situaciones beneficiosas para todos fomentó la creación del Parque Nacional Corcovado, y puede ser la clave para su sostenibilidad.PALABRAS CLAVEConservación, historia, Costa Rica, sistema de parques, conservación tropical, Península de Osa.

Abstract1. Mating and aggressive behaviour was observed in four species of dendrobatid frogs in Corcovado National Park, Costa Rica: Colostethus nubicola, Colostethus talamancae, Phyllobates vittatus and Dendrobates granuliferus. 2. Males of both species of Colostethus were more likely to respond to call playbacks than male P. vittatus or D. granuliferus. Male D. granuliferus were less likely to be found calling than males of the other species. Conspecific male-male aggression was observed in P. vittatus, but not in the other species. 3. Females were more active during courtship in P. vittatus. Female-female aggression was observed on one occasion in P. vittatus. Females were more likely to reject males than the reverse in all species. 4. These observations suggest that sexual conflict occurs in P. vittatus, but not in C. nubicola or C. talamancae.

Piedras Blancas National Park, in southern Costa Rica, is an important component of two biological corridors connecting the Osa Peninsula (Corcovado National Park) and La Amistad International Park. Understanding the mammal community composition of Piedras Blancas will provide baseline data to evaluate the success of conservation efforts. We used camera traps and opportunistic observations to describe the medium-sized and large mammals of the park. We deployed camera traps for 1,440 trap nights (2016-2018). We detected 19 mammal species from seven orders and 13 families. Five species are globally threatened: Leopardus wiedii (Schinz, 1821), Saimiri oerstedii (Linnaeus, 1758), Ateles geoffroyi (Kuhl, 1820), Alouatta palliata (Gray, 1849), and Tapirus bairdii (Gill, 1865). We did not detect two locally threatened species, Panthera onca (Linnaeus, 1758) and Tayassu pecari (Link, 1795). Our research highlights a need for critical conservation work within the proposed biological corridor to support Costa Rica’s most threatened wildlife.

Corcovado National Park

The jaguar Panthera onca is threatened throughout its range and categorized as Near Threatened on the IUCN Red List. To inform conservation of the jaguar population in Corcovado National Park, Costa Rica, population size was estimated using data from a 3-month camera trap study. Individuals were identified from their coat patterns. The resulting density estimate of 6.98 ± SD 2.36 individuals per 100 km2 was lower than expected. The sex ratio was 1.33 males per female, and the minimum home ranges of two males were 25.64 and 6.57 km2. Hunting pressure on jaguar and white-lipped peccaries Tayassu pecari, the jaguar's main prey in the Park, may be responsible for the low jaguar density as space does not seem to be a limiting factor. The numbers of females may have been underestimated because of sampling bias and therefore the sex ratio obtained in this and similar studies must be interpreted cautiously. Better protection of the corridor that connects the Park with other protected areas is essential to guarantee long-term survival of the jaguar in Costa Rica.

Conservation Of Biodiversity

One of the main strategies to preserve biodiversity has been the creation of protected areas, and some authors argue that such action will also have economic benefits for the human communities involved. Nevertheless, in several countries a spatial coincidence between these areas and poverty has been registered. This work evaluated whether there was more poverty in Costa Rican districts that have larger areas in inland national park or biological reserves. As an estimator of poverty in the districts, the Costa Rican index of social development (ISD) was used. For the whole country, districts with protected (DPA) areas had a lower ISD than those without them (DNPA). This result was also observed in the Central and Huetar Caribe planning regions; the opposite happened in the Huetar Norte region. The differences between planning regions offer opportunities for further research.

The conservation of remnant populations of white-lipped peccaries (Tayassu pecari) in Central America depends on understanding their demography, but few quantitative data exist. We report survival and cause-specific mortality of 25 female and 11 male radio-marked adult (>1.0 year old) white-lipped peccaries monitored during February 1995 – February 2001 in Corcovado National Park, their largest stronghold in Costa Rica. Annual survival was lower for female (0.78; 95% CI = 0.68–0.88) than for male (0.94; 95% CI = 0.86–1.00) peccaries. Both sexes were poached and died in accidents but only females were killed by predators or died of unknown causes (but not poaching). In comparison with the demography of collared peccaries (Tayassu tajacu), the population of white-lipped peccaries in Corcovado National Park may be maintaining itself. Still, protected areas may need to be expanded and (or) more forcefully monitored to sustain white-lipped peccaries throughout their range if additional use by humans is likely to occur, especially given stochastic population processes and human population increases.
