A survey was undertaken in the Great Sandy Desert, Western Australia, to document changes in total plant species richness and the richness of plants of significance to Aboriginal people, with time since fire. Species richness was highest in the early post-fire seral stages, then declined with time as ‘fire ephemerals’ completed their life cycle. Culturally significant plants, which comprised ~42% of all plants recorded, were found in all seral stages but were most abundant in the early stages post fire. A fine-scale mosaic of seral stages created by frequent patch burning provides a higher variety of plant resources per unit area, increasing harvesting efficiency of culturally important plants.

火、植物物种丰富度和对澳大利亚沙漠原住民具有重要意义的植物

在西澳大利亚州的大沙沙漠进行了一项调查，以记录自火灾以来随着时间的推移，总植物物种丰富度和对原住民具有重要意义的植物丰富度的变化。物种丰富度在火灾后的早期序列阶段最高，然后随着“火灾短暂”完成其生命周期而随着时间的推移而下降。在所有序列阶段都发现了具有文化意义的植物，约占所有记录植物的 42%，但在火灾后的早期阶段最为丰富。由频繁的斑块燃烧产生的细鳞片级马赛克为单位面积提供了更多种类的植物资源，从而提高了具有重要文化意义的植物的收获效率。
