In recent years it has increased the concern and interest in determining the negative effects and mitigation actions to the impact of road networks on the environment. The objective of This project was to implement strategies for the conservation of mammal populations wild that are vulnerable to being hit tourist paths in the canton of Sarapiqui. The number of wild mammals trampled method recorded by direct counts along Route 126 from San Miguel de Sarapiqui to the Virgin (secondary roads) following Route 4 from Chilamate, Puerto Viejo, El Tigre, Horquetas, San Jorge to Santa Clara for a study area of 63 5 kilometers. Two monthly monitoring between 6:00 AM and 9:00 am made were identified and recorded monthly in a database. Road segments with more deaths were determined. They georeferenced with a GPS Garmin 76Cx, during the year 2009. A land use map was developed, is segments determined as fewer and larger forest 10 hectares on both sides of the road, and death points trampled species found in 2009 were placed. Environmental education plan was developed with the activities that were implemented to 146 children, of near schools sampling route. A total of 39 field surveys were conducted for a sample area of 2476.5 kilometers, in this period were counted and identified a total of 231 animals killed on the road, the 91 which correspond to wild mammals, 55 violations were recorded in 2008 and 36 in the 2009. 91 were found wild mammals, a total of 86 individuals were identified, these are distributed five orders, seven families and eight species. Two species, the opossum (Didelphis marsupials) and armadillo (nine-banded armadillo) are the species most commonly killed by accident found a total of 62 individuals, there is a clear dominance of species Didelphis marsupials register more half of the abuses. The road segment comprised between Santa Clara and Cruce Forks, priority would be to establish high passes faunas. While the mortality of individuals is the most noticeable effect, roads and traffic flow, It has numerous consequences on wildlife.
