目前对海草诺氏斑藻的长期动态及其如何受到人为压力的影响的了解有限。米尔福德港是一个高度工业化的河口，也是英国Zostera sp.的重要地点之一。在本研究中，我们利用历史数据集分析了米尔福德港所有可用的诺氏短尾虫的长期空间变异和丰度数据。结果表明，与首次记录相比，所有样地的草甸面积均有所扩大。在过去的10-15年里，这两个地点的海草数量几乎没有变化，这证实了某些海草的数量是茁壮成长的。我们假设这些种群对Haven水体中存在的高营养水平、干扰和高浑浊度表现出一定程度的恢复能力。
There exists limited understanding of the long-term dynamics of the seagrass Zostera noltii and how this is influenced by anthropogenic pressures. Milford Haven is a heavily industrialised estuary and also one of the important sites for Zostera sp. in the UK. In this study we examine all available long-term spatial variability and abundance data of Zostera noltii within Milford Haven using historic datasets. Results show that Z. noltii in all sites have shown meadow expansion when compared to the first obtainable records. Little change in abundance over the past 10-15 years for the two sites confirms certain seagrass populations to be robust and thriving. We hypothesise that these populations are showing a level of resilience to the high nutrient levels, disturbance and high turbidity present within the water column of the Haven.
