the state of biodiversity<br />

the state of environment in Brazil<br />

Indigenous Lands (TI) are also important for in situ<br />

biodiversity conservation With a total of 586 areas, TI<br />

occupy a total extension of 105,091,977 hectares (123 percent<br />

of the continental area of the country), 98 percent of which<br />

are situated in the Legal Amazon (ISA, 2002) When added<br />

to federal and state conservation units, the percentage of<br />

protected areas, with different degrees of protection<br />

increases to 2078 percent of the national territory<br />

As demonstrated by the various factors addressed, Brazilian<br />

biodiversity has suffered significant losses and will only be<br />

preserved through the protection of large areas that enable<br />

the maintenance of viable ecosystems and of evolutionary<br />

processes Despite this alert, the existing protected areas in<br />

Brazil are, in general, small, isolated and their<br />

implementation presents various problems Moreover, the<br />

conservation unit system, often directed towards the<br />

protection of some species and ecosystems, is not sufficient<br />

to conserve the biodiversity totality The current system<br />

does not account for the protection of gradients between<br />
