Abstract

SOCOLOWSKI, Fábio et al. Restoration in Caatinga: a proposal for revegetation methods for the most exclusive and least known ecosystem in Brazil. Multequina [online]. 2021, vol.30, n.2, pp.247-263. ISSN 1852-7329.

In this paper we present the main ecological restoration techniques developed to meet a need to restore dry areas in Brazil impacted by great infrastructure works. A set of inexpensive and easy to execute nucleation techniques was developed to recover very degraded areas, considering both the elements of deforested areas and the surrounding landscape conditions. Five types of intervention have been proposed, ranging from simple monospecific direct seeding to the use of remnants of branches and cacti to form a protective fence for planted seedling nuclei. Until now, these are the techniques more adapted to field conditions, without irrigation aid and with low maintenance costs. We believe that long term monitoring of these techniques will provide more robust evidence of their effectiveness, but the preliminary results are positive. The restoration of Caatinga is a huge challenge for the science of restoration in Brazil, as well as an opportunity to develop new methods and techniques for ecological restoration.
