Habitat point records from 1981 Brathay Exploration Group Foula littoral survey

The intertidal flora and fauna of the rocky shores of the eastern coastline of Foula, Shetland Isles, were surveyed during July/August 1981. Ten primary shores were studied in detail : Da Rigs, North Boulder Beach, Ruscar, Head O'Da Taing, Trolli Geo, Head O'Da Baa, Dog Geo, Da Doon Banks, Surpeidle and Fisheads. Cover/abundance values were estimated fro the seaweeds and sedentary fauna present on the belt transects. Maps showing the accessibility, exposure and vulnerability to oil spillages were prepared for the island. Dogwhelk populations were sampled on each primary shore, length/aperture ratios calculated and related to wave exposure on each shore. The tidal range for the island is about 2m. Transects were set up from the low water mark to the top of the shore. Stations were located at 0.2m intervals up the shore. At each vertical station the abundance of the species present was recorded in a 5m * 0.2m quadrat. Shore profiles were also measured.

1981年7月至8月，对福拉岛东部海岸的岩石海岸潮间带生物群落进行了调查。详细研究了十个主要海岸：达里格斯、北博尔德海滩、鲁斯卡、奥达坦恩角、特罗利格奥、奥达巴角、狗格奥、达多恩银行、苏佩迪勒和鱼头。通过横断面调查，对存在于潮间带的海藻和底栖动物的种类覆盖度/丰富度进行了估算。为该岛制作了展示可达性、暴露度和易受石油泄漏影响的地图。在每个主要海岸对狗螺种群进行了采样，计算了长度/开口比，并将其与每个海岸的波浪暴露度相关联。该岛的潮差约为2米。从低潮线到海岸顶部设置了横断面。海岸线上每隔0.2米设置一个站点。在每个垂直站点上，记录了5米×0.2米的样方内现有物种的丰富度。还测量了海岸剖面。
