In Australia, seagrass loss associated with human activity is one of the most serious issues affecting the marine environment. Despite this, processes contributing to maintenance of seagrass meadows are poorly understood. This project addresses meadow maintenance through measuring seedling recruitment, clonal growth and patch dynamics for 3 species of seagrasses, and modeling emergent patterns of meadow expansion. The outcomes will be integration of shoot-scale and meadow-scale dynamics in shallow subtidal landscapes, resulting in a clearer understanding of and ability to manage large-scale changes in seagrass meadows caused by natural and anthropogenic influences.

在澳大利亚，与人类活动有关的海草损失是影响海洋环境的最严重问题之一。尽管如此，过程有助于维护海草草甸知之甚少。本研究透过量测三种海草之幼苗补充、无性系生长与斑块动态，以及模拟草地扩张之紧急模式，探讨草地维持之问题。其成果将是在浅水潮下带景观中整合拍摄规模和草甸规模的动态，从而更清楚地了解和管理自然和人为影响造成的海草草甸大规模变化的能力。
