Avaliação de algumas técnicas de nucleação em área degradada no Seridó da Paraíba.

Abstract

The concern over environmental issues, especially in regard to the uncontrolled use of natural resources, has been reflecting a high degree of environmental degradation. Improper use of the environment causes a break in the natural dynamics of the ecosystem, damaging it generally to all the elements that compose it. Therefore, this study was designed to examine the potential use of nucleation techniques. The study area is located in Cachoeira de São Porfirio Farm in the city of Varzea, micro-region of the Seridó, in the hinterland of Paraiba. Windrowing of brushwood was implemented which became artificial shelters for wildlife and action of decomposers. It was observed during the experimental period major decomposition of the material forming brushwood. This shows one of the features of this type of practice, which is to increase the content of organic matter, that is a source of food for soil biota. And being the artificial perches heavily visited by birds, and used as a resting place. During the 12-month period, 125 seeds of the species Jatropha curcas (pinhão manso) were found in collectors. The use of perches by birds was visible during the experimental period showing that birds are acquiring the habit of using the structures resulting in an increase in seed rain. The nucleation techniques have different features and particularities that if they are applied together, they will act in favor of the natural succession and restocking of the area.
