Pisces Conservation: Featured projects: #2 - Stream support monitoring, Salisbury Plain
|In 2001, Pisces Conservation were asked to carry out monitoring work on a chalk stream on the southern edge of Salisbury Plain in Wiltshire. In order to mitigate low natural flows in summer, the stream was augmented by water pumped from a borehole, to support flow rates, and hence fish, invertebrate and plant populations, in the lower reaches of the stream.
Pisces were required to survey macrophytes (particularly water-crowfoots, Ranunculus spp.), macroinvertebrates, molluscs and fish, to assess whether biodiversity was affected by stream augmentation.
|Detailed macrophyte surveying was carried out along the entire length of the stream, with point surveys, including electric fishing, invertebrates and molluscs. In addition a separate survey on the status of Ranunculus spp. in the stream was undertaken.
|Pisces staff have considerable experience in freshwater macroinvertebrate ecology, botanical surveying, and electric fishing, as well as statistical methods for analysis of survey data.
