Management options to minimise formation of urchin barrens: using belt transect surveys to monitor benthic community structure

Belt transect surveys (50m) were used to monitor the benthic community structure through time at experimental (lobster additions/ research reserve sites or abalone diver urchin culls) and control sites in eastern Tasmania. Measures of percentage cover of key algal guilds, percentage of reef grazed by sea urchins, number of sea urchins (Centrostephanus rodgersii, Heliocidaris erythrogramma), Abalone (Haliotis Rubra), Rock lobsters (Jasus edwardsii) and type of substratum were recorded.

本数据集采用50米带状样带调查（Belt transect surveys），对塔斯马尼亚东部实验样地与对照样地的底栖群落结构随时间的动态变化开展监测。其中实验样地涵盖龙虾投放样地、研究保护区样地，以及由鲍鱼潜水员实施海胆清除作业的样地。本次调查记录了多项监测指标：关键藻类功能群的盖度百分比、海胆啃食礁体的比例、两种海胆（Centrostephanus rodgersii、Heliocidaris erythrogramma）、红鲍（Haliotis Rubra）、岩龙虾（Jasus edwardsii）的数量，以及基质类型。
