3. Result and Discussion
In 1980, the predominant element in the both conservation areas was the Tropical
Rainforest both in Sustainable Development Reserve of Despraiado like in Juréia-Itatins State
Ecological Station (Figure 2). After 27 years of the federal act of the JISES was observed that
the land uses increased and vegetation cover decreased dramatically. In this unit left 34% of the
Tropical Rainforest and had an increased by 47% in agriculture and 83% the banana inserted
into the forest. The data indicate that most of the forested areas have been transformed by man
in uses, such as for crops, pastures, buildings and access roads.
On the other hand, the agriculture gained area in the JISES and in the SDRD. Observed that
in SDRD, the area of Tropical Rainforest Secondary Medium lost area for the agriculture, for
the Tropical Rainforest Secondary Initial and for the forest with bananas. The fact is this area
has been suffered strong influence of human activities and the legal acts have not been respected
(Figure 3).
The buffer zone is an area that has strong impact since 1980. The probable reasons are the
little distance from an important highway, the road Padre Manoel da Nóbrega. Moreover, it is
surrounded by many little cities. In 1980 can be observed a big area for agriculture like as
banana plantation and in 2007 the area decreased. In terms of gains and losses relating, this area
presents a lose in terms of Tropical Rainforest but gained in terms of uses that caused impacts in
the area.
In this way, we can conclude that the main goal of the creation of conservation areas has not
been reached, in other words, recovery, conservation and protection of the forest, which was
established by National System of Conservation Units.
