Vulnerable marine benthic animals – observational data Hard-bottom coral forest

The data set shows the relative amount of hard-bottom coral forest. The amount is calculated as the number of observations per video station. The data represent point observations and are suitable for comparing results from spatial predictive models for different vulnerable habitats and as a background for the management of vulnerable areas. In lively places with hard bottoms, horn corals can form habitats for fish, snake stars and small crustaceans. The most common species of horn corals that form hard-bottom coral forests are Paragorgia arborea, Primnoa resedaeformis, Paramuricea placomus and Swiftia spp. Although the diversity of species associated with the various horn corals that form this biotope is smaller than that of coral reefs, the fauna can be considered both individual-rich and rich in host-specific species that do not occur in other habitats.本数据集展示了硬质底质珊瑚林（hard-bottom coral forest）的相对丰度。该丰度以各视频观测站位的观测样本数为计算依据。本数据集属于点位观测数据，可用于对比不同脆弱生境的空间预测模型结果，同时也可作为脆弱区域管理的背景参考资料。 在硬质底质的活跃生境中，角珊瑚可为鱼类、蛇尾类及小型甲壳类动物提供栖息场所。构成硬质底质珊瑚林的常见角珊瑚物种主要包括Paragorgia arborea、Primnoa resedaeformis、Paramuricea placomus以及Swiftia属物种。尽管该生物群落生境中各类角珊瑚所关联的物种多样性低于珊瑚礁，但其动物群落不仅个体数量充沛，还拥有大量仅分布于此的宿主专一性物种。
