Population density ﬁgures, for example, obscure patterns of population distribution within areas.

Agriculture is widely considered the single most important threat to biodiversity conservation and the greatest driver of habitat destruction and change in Central America. Historically, agriculture has had a negative impact on biodiversity conservation primarily through the expansion of the agricultural frontier, at the expense of natural habitat. This biodiversity hotspot originally covered about 1.2 million square km. However, due to coffee and sugar plantations, the forest was decimated to less than 0.1 million square km. The hotspot provides habitat for 8,000 endemic plant species and around 950 birds. More than 25 species in the forest are critically endangered.
