Last known river based population of White-clawed Crayfish in Essex could be in trouble.

On Friday we were running our annual White-clawed Crayfish training day, run by Martin Pugh who is an ecologist for EECOS, which is Essex wildlife Trust's in house ecology consultancy. Not only does this give people the opportunity to  learn more about this increasingly rare species but also gives us the opportunity to monitor how the population is faring.

During the survey of Stebbing Brook we were quite concerned when only 18 adults were found and of these 16 had White Porcelain Disease. This is not to be confused with the crayfish plaque, which is carried by invasive crayfish for which our native species has no immunity to. White Porcelain Disease is a naturally occurring disease within native crayfish population but does not exceed 10% infection rate within a healthy population. To find so many of those captured on Friday to be infected was quite alarming as was the fact that we did not find any juveniles. Read more...

Giant Hogweed FAQ

How valueable has the Catchment Based Approach been to its hosts, Essex Wildlife Trust?

Essex Wildlife Trust has been involved in the Catchment Based Approach (CaBA) for nearly five years and has hosted the Combined Essex catchment since 2013.

The Essex Rivers Hub (the Combined Essex Catchment Partnership) has been selected as one of six catchment partnerships to be examined and one of two partnerships to be interviewed and questioned in detail. This selection was made because ERH has been identified as being very successful in the range of activities and the strength of the partnership and our commitment to the Catchment Based Approach (CaBA - the umbrella under which the Water Framework Directive and related activities are being progressed by the EA and Defra).

Digitised River Corridoor Surveys on NBN

Essex Wildlife Trust was recently awarded funding from the NBN Trust to digitise river corridor survey data for the Rivers Blackwater and Pant, collected by the National Rivers Authority in the early 1990s. This was part of a wider initiative to mobilise data using funding received from the Cabinet Office via their Release of Data fund.

The data consists of sketch maps, summary information and detailed botanical surveys of the Pant and Blackwater, and of a tributary of the Pant, the Finchingfield Brook. This data was held in paper format by the Environment Agency and digitised by Essex Wildlife Trust Biological Records Centre as part of our ongoing partnership work with Essex Biodiversity Project and the Environment Agency, aimed at sharing information on Essex Rivers.
