About us

Nicky Green is an ecological consultant and researcher specialising in the conservation of native freshwater crayfish and advising on the control of invasive crayfish species. Advice is based on years of practical experience combined with a thorough understanding of current scientific knowledge.

Nicky provides survey and monitoring, training and advice on crayfish conservation and management  

Nicky  has been working with crayfish since 2003, initially monitoring native white-clawed and signal crayfish on the River Creedy/Yeo in Devon for the local Environment Agency (EA) Team. After ‘rediscovering’ an extant population on East Devon’s River Culm in 2005, works extended to that river. Involvement with the South West Crayfish Project from 2008 led to working with the EA, Buglife, Bristol Zoo and the Avon Wildlife Trust translocating white-clawed crayfish to ‘ark sites’ in Devon and helping to set up a captive breeding facility and public exhibit at Paignton Zoo.

Nicky has also worked extensively with the EA and other organisations providing advice on potential impacts of different activities, such as bridge repair, on white-clawed crayfish populations and provided  mitigation strategies for works that could impact on native crayfish.  

Since 2014 Nicky’s main focus has been on a number of projects including the River Barle Signal Crayfish Project and Exmoor Non-Native Invasive Species (ENNIS) projects on Exmoor and the Culm Community Crayfish Project. Current partners/clients include the Environment Agency, Exmoor National Park, Blackdown Hills AONB and South West Water.

Nicky is studying part time for a PhD with Bournemouth University investigating the efficacy of trapping and male sterilisation as a signal crayfish control method. This research is based on her work on the River Barle and supported by various experiments carried out under controlled conditions at the University. She has presented her research at crayfish conferences in Yorkshire, Madrid, Pittsburg and Helsinki.

Another focus is the development of and research into the Artificial Refuge Trap which is more economical and less biased than conventional funnel traps. Nicky manufactures and sells Artifical Refuge Traps (ARTs) to help support her research.
