Survival and growth of Bauhinia forficata Link., Erythrina cristagalli L. and Eugenia uniflora L. on multifunctional windbreak in a agroecosystem of family production in southern Rio Grande do Sul

Abstract

Given the current environmental scenario, with intense fragmentation and suppression of natural
ecosystems and the changes in Brazilian environmental law, it is necessary to develop
ecological restoration strategies for agroecosystems. Multiple uses windbreaks being an alternative
to ally the environmental issue to income generation. There is still little knowledge about
the behavior of native tree species in their establishment and early development in the field.
The objective of the this work was evaluate the survival and growth of three native trees in
the extreme south of Brazil, Bauhinia forficata, Erythrina cristagalli and Eugenia uniflora . The
species E. cristagalli and E. uniflora showed 100% survavil rate, with E. cristagalli standing out
for growth. The three species presented promising results, being indicated for use in vegetable
curtains and ecological restoration projects.
