Evaluation of Forest Restoration in a Degraded Permanent Preservation Area in Santa Catarina State, Brazil

This study evaluated the process of restoration in a degraded Permanent Preservation Area (PPA) in the municipality of Pouso Redondo, Santa Catarina state, six years after the initial plantation of trees and isolation of the area. Tree species were surveyed and increment of richness by natural establishment was quantified. Syndromes of propagule dispersion and regeneration guilds were determined. A total of 918 individuals from 73 species were found; 48 (65.8%) of them were species naturally established in the area. 71.2% of the species were classified as zoochoric (71.2%), and 54.8% as light demanding for climax. After six years, the restoration process was characterized by a trend of richness increment and replacement of initial by late successional species, indicating the relevance of the natural regeneration mechanism.

本研究针对圣卡塔琳娜州波苏雷东杜市一处受损的永久性保护区域（Permanent Preservation Area, PPA）开展修复进程评估，该区域在完成初期植树与隔离管控后已历时六年。本研究对区域内树木物种进行全面调查，并量化了通过自然定植实现的物种丰富度增幅，同时明确了植物繁殖体传播综合征类型与更新功能群划分。本次调查共记录到73个物种、总计918株个体，其中48个物种（占比65.8%）为该区域自然定植的物种。其中71.2%的物种被归类为动物传播型（zoochoric），54.8%为顶极群落需光物种。修复实施六年后，该区域的修复进程呈现出物种丰富度逐步提升、先锋物种被晚演替物种逐步替代的特征，表明自然更新机制在此次修复过程中具有重要意义。
