Avaliação e monitoramento de técnica de restauração ecológica para áreas de preservação permanente do Rio Amambai, município de Amambai, MS

Abstract

This study aimed to evaluate the development of tree species subjected to planting in rows in Permanent Preservation Area of Rio Amambai in the town of Amambai, MS and thereby provide indicators for monitoring technique. To implement the experiment took place prior cleaning the entire area by mechanical weeding, handheld and mechanized tillage and fertilization (110 g of 4-28-6 per plant). Gone planted 242 seedlings of 25 native tree species (Table 1) were planted in an area of 1520 m2 in rows at spacing of 3 x 2 m, arranged in rows fill with fast-growing pioneer species and dense canopy, and lines of diversity, other species, pioneers and non-pioneers. Of the 242 seedlings planted in permanent preservation area, 122 seedlings, in other words, 50,41% died during the second and third reviews. This mortality rate shows that some species showed low tolerance to frost factor influencing negatively the same. The species which were the most developed went the Enterolobium contortisiliquum (Vell.) Morong e Albizia lebbeck (L.) Benth., reaching over 2 meters in less than 1 year. It is observed that there has been rapid growth in height of planted individuals, 11 months after planting, showing that the action is being adopted restore effective with regard to the establishment of individuals in the area.
