Here Graham Hill provides an update on the detailed studies and monitoring of White-clawed Crayfish that have taken place annually since 2010. After a disastrous year in 2016 when Crayfish Plague spread from Dowles Brook into further tributaries, this article provides current population data together with some very interesting conclusions around the possible mechanisms involved in the spread of Crayfish Plague.
Annual monitoring of native White-clawed Crayfish Austropotamobius pallipes in streams of the Wyre Forest commenced in 2010. The ninth survey was undertaken during 2018 when a reduced number of streams that have held populations of White-clawed Crayfish were resurveyed. Graham & Christopher provide details of the latest finding of this important study.
The term eDNA is simply defined as a source of DNA which can be found within environmental samples such as water, soil, or air. Here Christopher Troth explains how this technique has been used in the ongoing studies of Crayfish populations in the Wyre Forest.
Annual monitoring of native White-clawed Crayfish Austropotamobius pallipes in streams of the Wyre Forest commenced in 2010. The eighth survey was undertaken during 2017 when all streams that have held populations of White-clawed Crayfish were resurveyed. Graham Hill provides details of the latest finding of this important study.
This article describes the use of artificial crayfish refugia (‘panpies‘) to examine the distribution of White-calwed crayfish in one Wyre stream. Crayfish Plague was detected in this stream, the migration of the effects of plague in the crayfish population is discussed.
Annual monitoring of crayfish in streams within Wyre has been undertaken since 2010, and this article provides information about the 2013 survey and distribution of our native crayfish in the streams studied.
The annual monitoring of parts of Wyre Forest’s water courses for White-clawed Crayfish is described. This article provides results from the 2012 survey and compares the finding with data from previous years.
A catchmentwide crayfish survey of Dowles Brook was completed in 2011, this article documents the methods used and the results. Information about historical crayfish monitoring in Wyre and comparison with present day status and distribution is provided.
A crayfish survey of parts of the Dowles Brook catchment was undertaken in 2010. This report details the current status nationaly and the habitat requirements of the species, the methods used in the survey along with the results.
