pockets of forest covering more than 100,000 hectares, while other areas covering only 100hectares or less (Consórcio 1992).Figure 2: Map showing the remaining forested areas of the Mata Atlântica.Source: Iracambi Recursos NaturaisStretching along the Atlantic coast, the Mata Atlântica’s location has in fact been detrimentalto its existence, as it was the area first penetrated <strong>and</strong> settled by the Portuguese. Trading citieswere established along the Atlantic coast to expedite the allocation of forest resources such astimber. L<strong>and</strong> was cleared for agriculture to support the growing colony, <strong>and</strong> animals werehunted for food <strong>and</strong> sport. The Mata Atlântica has suffered greatly in the last half century,<strong>and</strong> the activities of man all but doomed the forest. Sprung up from the days of Portuguesetrading cities, the region of the Mata Atlântica is now home to 80 million people—nearly halfof the total population of Brazil. As a result of relentless pressures from man for l<strong>and</strong> <strong>and</strong>forest resources, the Mata Atlântica is one of the world’s most threatened ecosystems (Rees1990, Le Breton 2000).The Mata Atlântica is in fact not one ecosystem, but several. The region can be divided intoseveral different forest typologies including montane rainforest, conifer forest, mangroves,<strong>and</strong> even grassl<strong>and</strong>s. The focus of this study, however, is on the lower-montane rainforestfound between 800 <strong>and</strong> 1800 meters, primarily along two coastal mountain ranges of EasternBrazil, the Serra do Mar <strong>and</strong> Serra da Mantiqueira. This area is located in the states of SaoPaulo, Minas Gerais, Rio de Janeiro, <strong>and</strong> Espirito Santo. The other typologies of the MataAtlântica include grassl<strong>and</strong>s in a few areas of the forest’s northernmost range <strong>and</strong> onelevations higher than 1800 meters (upper-montane rainforest), semi-deciduous <strong>and</strong> coniferforests in the south, <strong>and</strong> mangroves at the coast (Rizzini 1988). However these areas are lessinteresting in the context of biological diversity, as it is the tropical rainforest that is theEarth’s most structurally diverse <strong>and</strong> ecologically complex biome. In fact, Whitmore (1990p.9) concludes that rainforests “are the apex of creation.”9
