Legally protect habitat for mammals Terrestrial Mammal Conservation

A systematic review in 2013 of the effectiveness of protected areas across the globe, but especially in Latin America (Geldmann et al. 2013) found that 24 of 31 studies reported an increase in mammal populations in protected areas relative to unprotected areas. Seven of 31 studies reported a decline or no change in mammal populations in protected areas relative to unprotected areas. Twelve studies used a before-and-after methodology and 19 studies were site comparisons.
