Abstract
analysis Abstract This study aimed to determine and analyze landscape ecology metrics to characterize the spatial pattern of fragments of native forest in São Mateus River basin, Espírito Santo State, Southeastern Brazil. Fragments were divided into four size classes called C1 (<5 ha), C2 (5-25 ha), C3 (25.10-50 ha) and C4 (>50 ha). Metrics were grouped according to their nature in (i) area and density, (ii) edge, (iii) shape, (iv) central area and (v) proximity. In total, 4,286 native forest fragments were identified, which represented 7.80% of total area of the basin. There is a predominance of fragments with more regular shapes, small (<25.10 ha) and, consequently, with greater edge effect. Results showed that the drainage basin studied is highly fragmented, which reinforces the need for strategies aimed at forest conservation and restoration of degraded forests in this region.
期刊介绍：
Scientia Forestalis is a scientific publication of the IPEF – Institute of Forest Research and Studies, founded in 1968, as a nonprofit institution, in agreement with the LCF – Department of Forest Sciences of the ESALQ – Luiz de Queiroz College of Agriculture of the USP – São Paulo University. Scientia Forestalis, affiliated to the ABEC – Brazilian Association of Scientific Publishers, publishes four issues per year of original papers related to the several fields of the Forest Sciences.
The Editorial Board is composed by the Editor, the Scientific Editors (evaluating the manuscript), and the Associated Editors (helping on the decision of acceptation or not of the manuscript, analyzed by the Peer-Reviewers.
