Ecosystem analysis of the Serra do Mar Paraná, portion of Marumbi's area of special tourist interest

Abstract

Protected areas aim to conserve biodiversity. Analyzing biotic and abiotic relations of the Marumbi Area of Special Tourist Interest (AEIT), located in the Serra do Mar Paraná State and which includes five State Parks in a mountainous environment under the domain of Dense Ombrophilous Forest, we seek indicators of ecological effectiveness. Through the construction and cartographic interpretation, georeferencing, intercrossing of geological, geomorphological, hydrographic, vegetative, elevation, slope and perimeter of protected areas (UC), the distribution of 3,703 springs over 66,000 hectares (ha), average of one every 18.02 ha. Most in Montana (600 to 1200m s.n.m.) with 53% and Submontana (30 to 600m s.n.m) with 26.5%. Unlike the bibliography consulted that indicated abundance of springs at the summits; The result was 6.7% in Altomontana and 1.8% in Altitude Fields (over 1200m s.n.m). In the intersection of springs with geological domains, granite presents 57.7% of occurrence and the migmatitic complex 35.2% being the most representative unit/area ratio. Only 20.4% of the springs are in full protection protected areas (ucs) analyzed.
