Conserving a Newly-Discovered Population of the Critically Endangered Robber Frog Craugastor ranoides in Nicaragua

The objectives of this project are to lay a scientific framework for the future conservation of this population of Craugastor ranoides by establishing baseline data on population size, demographic composition, seasonal fluctuations, and reproductive patterns. This species has been extirpated in all but one location in Costa Rica, and although its extant range includes Nicaragua, it has not been documented in the country since the 1990's. We have recently documented the presence of C. ranoides in a single small stream along Lake Nicaragua's southern shores the second known location currently harboring this species in the wild. This location is thus of high conservation importance; however, the population remaining is likely small, given the limited size of the stream harboring these individuals. Such a population will require careful management and frequent monitoring to prevent declines. However, such action is impossible without baseline data on population size, distribution, and reproduction. It is also possible that other streams in the area could harbor additional individuals; thus we will conduct additional intensive searches in other nearby streams. Signage and patrols will prevent unauthorized entry into the areas supporting these critically endangered amphibians

 

This project is being carried out by Paso Pacífico; our mission is to restore and conserve the natural ecosystems of Central America’s Pacific slope by collaborating with landowners, local communities and involved organizations to promote ecosystem conservation. Paso Pacifico envisions a Central America where well-managed conservation areas are connected by biological corridors spanning ridge to reef. By rebuilding forests and connecting ecosystems from land to sea, we are actively combating climate change and saving endangered wildlife. Paso Pacifico’s current work specifically targets Nicaragua’s Paso del Istmo. Located along the 12-mile-wide isthmus between Lake Nicaragua and the Pacific Ocean, this narrow passageway has historically served as a land bridge for wildlife migrating between North and South America. In recent decades, however, irresponsible land development and rapidly increasing international investments have had serious consequences for the region’s climate, forests, and wildlife. The Paso del Istmo’s potential to connect numerous distinct ecosystems in such a short distance makes it a strategic component to conservation in Nicaragua. Its close proximity to complete ecosystems in neighboring Costa Rica means that wildlife can repopulate restored and protected forests. Our projects integrate conservation and sustainable development, reflecting our holistic vision for conservation in Nicaragua's Paso del Istmo.
