How well do revegetation plantings capture genetic diversity

摘要: Revegetation plantings are a key management tool for ecological restoration. success is usually measured using traits, however, genetic diversity should also be considered as it can influence fitness, adaptive capacity and long-term viability of revegetation ecosystem functioning. Here we review the global literature comparing in to natural stands. Findings from 48 studies suggest variable outcomes revegetation, with 46% demonstrating higher than stands 52% lower diversity. Levels were most strongly associated number source sites used-where information was available, 69% showing reported multiple provenances, compared only 33% those However, few exceptions, unclear whether differences between statistically significant. This reflected insufficient reporting statistical error metadata within published studies, which limited conclusions about factors contributing patterns. Nonetheless, our findings indicate that mixed seed sourcing contribute revegetation. Finally, emphasize type needed determine influencing inform restoration efforts.
