Ecology and conservation of breeding common scoters
This project aims to find out how we can reverse the population decline of breeding common scoters.
- To determine the factors correlated with lake use by breeding common scoters in Britain and interpret these in relation to options for scoter conservation.
- To determine whether the abundance of large invertebrates (which are typical scoter prey in freshwaters) was correlated with fish abundance and/or water quality.
- To test whether reductions in trout abundance lead to increased availability of large freshwater invertebrates and hence improved habitat quality for breeding scoters and other waterbirds.
- 2009-2011: a three year study of common scoter breeding ecology was carried out, at 26 lakes holding about half of Britain's breeding scoters.
- 2013-2018: a six year trial management project was established at Forsinard RSPB reserve, testing the effect of trout management by angling, on invertebrate abundance and lake use by scoters.
