The evolving wetlands at Bamff have proven to have enriched the habitat, providing a greater abundance and variety of insect species than in neighbouring locations where the beavers are absent – often by a factor of 3 to 4. This has had a subsequent effect on insectivorous birds and mammals, where species such as swallows, flycatchers or bats have been spotted in greater numbers feeding at beaver sites, and rarely at all in non-beaver sites.

Moth and other insect trappings occur regularly at Bamff – since 2022 PhD student Patrick Cook from the University of Sterling has been regularly studying the impact of rewilded fields on our invertebrates. With positive results.
