The Tacaná Volcano Biosphere Reserve, on the Mexico-Guatemala border, is a region of great biological and cultural richness. The MAM culture was born there. This cultural heritage flourishes along with an incredible biodiversity where many of its species are endemic and threatened by human activities. Fire is the main threat to the reserve. Every year, hectares of forest are lost due to arson. CONANP [Comisión Nacional de Áreas Naturales Protegidas = National Commission of Protected Natural Areas] park rangers perform work training community brigades, teaching in the communities and fighting fires when they occur.
