Adopt community-based management to protect forests Forest Conservation

A replicated, site comparison study in 1985–2002 in 19 sites in tropical rainforest in Colombia (Armenteras, Rodriguez & Retana 2009) found that deforestation rates in indigenous reserves did not differ from those in surrounding forests, or those in uninhabited protected national parks. Deforestation rates in 14 indigenous reserves (0–1.99 %/year) did not differ from the forests surrounding them (0.01–2.89 %/year), or those in five protected national parks (0.02–0.17 %/year). However, the deforestation rate in national parks (0.02–0.17 %/year) was lower than in forests surrounding the parks (0.03–0.97 %/year). Deforestation rates were based on satellite images (Landsat, resolution 30 m) of the region taken in 1985, 1992 and 2002. The surrounding forest was defined as the forest within 10 km of the border of the parks and the reserves.
