Abstract
This work intends to study the environmental impacts and to suggest proposals for
preservation and recovery of the degraded areas of a mangrove located in the so called
Parque Ecologico Municipal Dormitório das Garças, located near the Porto do Carro, in the
city of Cabo Frio, RJ. Because the area is inside the largest hypersaline lagoon in the world,
mangrove is of special importance; a population of about 1.400 white herons and seasonal
visitors, in an amount of 41 avian species, use it as shelter area. Predominantly it is a black
mangrove (siriubal) with an area of 215.000 sq.m. No systematic contribution of fresh
water flows throughout the mangrove, the relief is plane, climate is dry, heat is high,
rainfall is low and winds are constants. The progressive and accelerated leaves breakdown
that occurs in the mangrove vegetation leads to a great concern of the citizens.
Methodology applied relates causes to effects among the components of the system: water,
sediment, flora, fauna, topography and climate, by comparing vegetation and nonbiotic
factors in their respective compartments. High soil carriage resulting from the dredging of
the Lagoon of Araruama Channel, which started during 2001, associated to unsuitable
disposal of dredged material, reduces water circulation and disturbs water tides entrance
and exit The elevation of the highway for accessing the Ilha dos Ratos resulted in water
stagnation mainly in the northern portion of the mangrove. This procedure changed
drastically the dynamics of the system. Environmental risks assumed with the dredging of
the Lagoon of Araruama Channel, as well as the indiscriminate release of sewage, and the
duplication of the Estrada dos Passageiros, exceed the natural balance capacity of the
system. The Parque Ecologico Municipal Dormitório das Garças under administration of
the Secretaria Municipal de Meio Ambiente e Pesca de Cabo Frio, and based on a
Management Plan would be the basis of the mangrove sustainability.
