Assessing vulnerability of listed Mediterranean plants based on population monitoring

摘要: Abstract Understanding the population dynamics of rare and endangered plant species is essential to elaborate correct management plans for their conservation. Demographic monitoring individual provides valuable information here. However, demographic studies are limited which one can follow individuals through life history. They also time consuming, making it difficult make simultaneous several with different populations in order have a more general assessment given region. In this paper, we illustrate how use an approach based on transition frequencies allows study comparison trends 32 six very histories growth forms Mediterranean region South France. The results show significant effects spring rainfall deficit annual but not perennial that delayed response, declines due direct human impacts Our illustrates alarming overall vulnerability simple rapid apply multi-population multi-species context. It could thus be used by conservation staff construct assessments elsewhere.
