A Message from the Environment Agency- Quagga Mussel

Information provided by the Environment Agency:

On the 7 October 2014 we reported our finding of the Quagga mussel (Dreissena rostriformis bugensis) in the Wraysbury River and Wraysbury Reservoir in Staines. Further investigations have confirmed that the Quagga mussel is also present in the Warwick East Reservoir, Warwick West Reservoir and William Girling Reservoir, all located in the Lee Valley.

Little Waltham Meadows is nearing completion

A few weeks ago we reported on the River restoration project at Little Waltham meadows. As a quick recap people will remember that the aim of the project was to create a new back channel in a previously dry meadow that offers additional wet habitat, a refuge for fish in time of high flow and filters out many of the pollutants coming through the land drain in a series of small stilling ponds.

The Invasive Quagga Mussel has been found in the UK

The Quagga Mussel (Dreissena bugensis rostriformishas) has been discovered in Wraysbury Reservoir near Heathrow Airport. If this mussel spreads it would have a severe affect on UK wildlife and may prove to be the most damaging non-native invasive species that has been introduced into this country so far.

To find out more please read the  news article and attachments available on Essex Wildlife Trust's new Biological Records Centre website.

Hand-drawn maps to be digitised

Historic data is something that is incredibly important and allows us to look at changes in the environment. Unfortunately many historic maps are hand drawn which means that they are not easily compared with today's digitised data.

Currently we have many staff and volunteers going through the laborious process of digitising this hand-drawn data. Although this takes time, this will allow comparison work to become quick and easy, helping to inform the management decisions of the future.

To view an example of a hand-drawn map of the Blackwater to be digitised please click here.

An insight into our rivers as they were 30 years ago

Here at head office we have just received some data from a 1984 fisheries survey. The way in which this data was stored then is very different to now; the documents below show hand written data tables with counts of fish from unidentified points across three rivers in Essex. It is brilliant for us to receive these records are they allow us to look at changes in populations over time. These changes can be for a wide range of reasons. Read more...
