Biodiversity Indicators 201703 Aug 2017
BTO’s volunteer-based monitoring schemes are integral to the wild bird indicators, providing constituent trends for more than just species. However, BBS participants who undertake butterfly surveys on their one-km squares are also contributing to the published trends in widespread butterfly species. The Priority Species indicator includes trends from a wide range of taxa such as BBS-derived trends for Brown Hare as well as many bird species. In terms of threats, the Non-Native Species indicator shows the increasing spread of a selection of invasive non-native species known to have negative environmental impact. On the plus side, involvement in conservation activities by the voluntary sector continues to grow. Read the full UK Biodiversity Indicators 2017 here.
