Many species of orchids in fragmented landscapes need active management to secure their persistence. The effects of fragmentation can be direct (e.g. reduction in population sizes, environmental quality, increased inbreeding, reduced dispersal ability), or indirect through negative effects on pollinators. Little information exists on the complex interactions between effects of fragmentation on plants and their pollinators. This project aims to understand how fragmentation affects the genetic diversity and demography of selected populations of orchids and their pollinators in the Mt.Lofty/Flerieu Peninsula area. This information will help to develop and implement more effective conservation plans.

许多种兰花在破碎的景观需要积极的管理，以确保其持久性。碎片化的影响可以是直接的（例如种群规模减少、环境质量下降、近亲繁殖增加、扩散能力下降），也可以是间接的，对传粉者产生负面影响。关于碎片化对植物及其传粉者的影响之间的复杂相互作用的信息很少。该项目旨在了解片段化如何影响在洛夫蒂山/弗莱留半岛地区的兰花及其传粉者的遗传多样性和人口统计学。这些信息将有助于制定和实施更有效的保护计划。
