Evaluation of patterns of pollen dispersal, mating systems, population fitness, genetic diversity and differentiation in restoration and remnant plant populations can be useful in determining how well restoration activities have achieved their objectives. We used molecular tools to assess how well restoration objectives have been met for populations of Banksia media in the biodiversity hotspot of south-west Western Australia. We characterized patterns of pollen dispersal within, and pollen immigration into, two restoration populations. We compared mating system parameters, population fitness via seed weight, genetic diversity and genetic differentiation for restoration and associated reference remnant populations. Different patterns of pollen dispersal were revealed for two restoration sites that differed in floral display, spatial aggregation of founders and co-planted species. Proximity to remnant native vegetation was associated with enhanced immigration and more short-range pollen dispersal when other population variables were constant. Greater seed weights at remnant compared to restoration populations were not related to outcrossing rate. Equivalent mating system and genetic diversity parameters and low to moderate levels of genetic differentiation between restoration and remnant populations suggest pollinator services have been restored in genetically diverse restoration populations of local provenance B. media as early as four years from planting.

南部平原波克西斯恢复中的花粉传播，花粉移入，交配和遗传多样性

对花粉传播模式，交配系统，种群适应度，遗传多样性以及恢复植物和残存植物种群分化的评估，对于确定恢复活动如何实现其目标非常有用。我们使用分子工具评估了Banksia媒体人群的恢复目标达到了何种程度在西澳大利亚州西南部的生物多样性热点地区。我们表征了花粉在两个恢复种群中的散布模式以及花粉迁移到两个种群中的特征。我们比较了交配系统参数，通过种子重量进行的种群适应度，遗传多样性和遗传分化的恢复和相关参考残留种群。对于两个恢复位点显示出不同的花粉散布模式，这两个恢复位点在花卉展示，创建者的空间聚集和共同种植的物种方面有所不同。在其他种群变量不变的情况下，邻近残留原生植被与移民增加和近距离花粉扩散更加密切相关。与恢复种群相比，残留处更大的种子重量与异交率无关。B.媒体距种植最早已有四年。
