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.  


In 2014 Nicky started working with the EA and Exmoor National Park setting up a signal crayfish survey of the River Barle Site of Special Scientific Interest. This volunteer led project has led to a ground-breaking control trial using a combination of male sterilisation and intensive trapping using a novel trap type developed and manufactured by Nicky.      


Nicky Green CEnv MCIEEM  is an ecological consultant and researcher specialising in the conservation of native freshwater crayfish and advising on the control of invasive crayfish species.
