Using bramble and dormouse nesting activity as a measure of the effectiveness of deer management in Bradfield Woods 2016 Alison Looser & Simone Bullion The monitoring programme assesses the quality and quantity of bramble cover along ride edge transects as well as fixed point photography, to assess the habitat quality in selected areas of the wood. In addition, a survey is undertaken in areas of suitable ride edge habitat to locate and count natural hazel dormouse nests.
Hen Reedbed aquatic invertebrate surveys 2012-15 2015 Adrian Chalkley During 2012 baseline freshwater invertebrate surveys were carried out on four sites at Hen Reedbeds. On December 6th 2013 a tidal surge inundated Wolsey Marsh on the Eastern side of the reserve. Further surveying 6 months later showed that both the size and composition of the invertebrate population had reduced considerably.
White-clawed Crayfish Conservation Strategy
Essex, Norfolk and Suffolk
2015 Environment Agency

The white-clawed crayfish was once widespread across Britain. They are now classed as an endangered species and we believe that they could become locally extinct. 
The greatest threat to white-clawed crayfish is from the non-native invasive American signal crayfish. 

This strategy summary outlines the aims to conserve white-clawed crayfish in refuges and ark sites, rivers or lakes that are suitable for the species to thrive but safe from invasive species.

Little Ouse River: Aquatic Invertebrate Survey 2014 Adrian Chalkley An ecological assessment of four sections of the Little Ouse River was carried out using aquatic macroinvertebrates as the indicator organisms.
Aquatic invertebrate survey of Oulton Marshes 2014 Adrian Chalkley Four turf ponds were excavated in 2011 at the Suffolk Wildlife Trust Reserve, Oulton Marshes and six more in 2013. These 10 ponds were among 21 areas of the reserve surveyed between August 2013 and September 2014.
Grove Farm
Progress report on a two year experiment monitoring changes in wildlife with Blackbourne U3A volunteers (University of the Third Age)
2014 Juliet Hawkins In 2012 Suffolk Wildlife Trust received a small bursary to train, equip and organise a monitoring project with the help of 20+ University of the Third Age volunteers on their 62ha Grove Farm nature reserve. The project aimed to contribute records of arable flora and colonisation of 20 restored and newly created ponds, especially priority species. Two years on, over 900 plant records have been recorded, including pockets of remnant declining arable flora; and nearly 400 pond records have been collated, including over 17 Nationally Notable Nb and Local aquatic invertebrates; other groups have been recorded too. In June 2014 The Freshwater Habitats Trust selected Grove Farm as a Flagship Pond Site.
