Vegetation types lacking protection in the existing conservation units
of the nine states in the Brazilian Legal Amazon were identified, and
locations were noted where these vegetation types could be protected.
Maps of vegetation, protected areas, and semi-protected areas, such a
s Amerindian and forestry reserves, were digitized and overlaid using
a geographic information system. There are 28 natural vegetation types
in the Brazilian Legal Amazon. Locations of new areas for protection
were selected using a minimum criterion of protecting at least one exa
mple of each vegetation type in each state (here called ''vegetation z
ones''). There are 111 vegetation zones in the Legal Amazon, of which
only 37 (33%) have some portion of their area protected. There are few
protected areas in the most heavily deforested states along the south
eastern fringe of the forest. In Maranhao, where 60% of the original f
orest had been lost by 1990, only one of 10 vegetation types is protec
ted. Negotiating agreements with indigenous tribes, and to a lesser ex
tent with extractivists who harvest nontimber products from the forest
, represents a major opportunity to increase significantly the area an
d representativeness of the conservation units. Additional conservatio
n units need to be established quickly before rapidly increasing defor
estation and land prices preclude this opportunity; otherwise, some ve
getation types may virtually disappear.
