The need for quick identification of priority areas for biodiversity protection makes rapid assessment methods important management tools for defining conservation strategies. An increasingly used rapid assessment method is rapid ecological assessment (REA), a fast and flexible survey directed toward selected indicator species and vegetation forms. The purpose of this study was to propose and test REA based on plant community features of the semideciduous Atlantic forest (SAF). Correlation tests were performed between data collected by REA and plant species diversity, richness, and abundance collected by conventional woody plant inventory methods. The study was conducted in 21 SAF patches in Northern Paraná State, Brazil. The phytosociological inventory was conducted along a single transect and required 2 days to complete (excluding time spent for herbarium identification), whereas REA was conducted along three to four transects per working day. REA results correlated positively with woody plant diversity, proving REA to be an efficient method for defining the conservation status of SAF fragments, but accuracy of evaluations of threats to biological integrity are relatively low. Both the selection of appropriate variables and the skill level of field staff are critical and can strongly influence REA results.
快速识别生物多样性保护优先领域的需求使得快速评估方法成为定义保护策略的重要管理工具。一种越来越被广泛使用的快速评估方法是快速生态评估（REA），这是一种针对选定指示物种和植被形式的快速而灵活的调查。本研究旨在提出并测试基于半落叶大西洋森林（SAF）植物群落特征的 REA。通过 REA 收集的数据与通过传统木本植物清查方法收集的植物物种多样性、丰富度和丰度进行了相关性检验。该研究在巴西北巴拉那州的 21 个 SAF 斑块中进行。植物群落学清查沿着一条单一的样带进行，需要两天时间才能完成（不包括标本鉴定所花费的时间），而 REA 则在每个工作日沿着三到四条样带进行。REA 结果与木本植物多样性呈正相关，证明 REA 是定义 SAF 片段保护状况的有效方法，但对生物完整性威胁评估的准确性相对较低。选择合适的变量和现场工作人员的技能水平都至关重要，并且可以强烈影响 REA 的结果。
