Qué es un plan de manejo ? El caso del Refugio Nacional de Vida Silvestre Caño Negro, Costa Rica

The black and the white rhinoceros have become flagship species for international conservation. They are significant not only for the continuation of a major evolutionary heritage, but also as symbols for the protection of African savannahs. The battle for the survival of these species has been marked by some notable successes and sadly, many failures, and the situation is still critical.
Although most antelope species still exist in large numbers in sub-Saharan Africa (some in hundreds of thousands), up to three-quarters of the species are in decline. Threats to their survival arise from the rapid growth of human and livestock populations, with consequent degradation and destruction of natural habitats, and excessive offtake by meat hunters. In addition, some parts of Africa are mow almost completely devoid of large wild animals because of uncontrolled slaughter during recent civil wars.
