Status and Trends of Biodiversity
Costa Rica has a large diversity of ecosystems grouped into the following categories: forests, wetlands, marine areas and agricultural areas. Costa Rica has identified a little over 87,000 species, which represents 6.2% of the known species in the world. The species distribution among taxa is as follows: 10,979 plant species and 2,430 vertebrate species including 935 fish, 857 birds, 243 mammals, 235 reptiles, and 182 amphibians. Historically, economic development increased at the expense of the country’s natural resources, particularly in the last half of the 20th century. However, Costa Rica has made progress towards more sustainable use of its natural resources. For example, it has decreased the deforestation rate from 43,000ha in 1983 and 13,000 in 1993, to an average of 5,000ha in the last 5 years.
