Barnsley Biodiversity Trust logo Barnsley Biodiversity Action Plan. DRAFT Last Updated February 2021

Invertebrates are an important component of biodiversity, often overlooked. Making up around seven out of every ten species overall, they pollinate our flowering plants, help create good soil by breaking down plant and animal waste material and act as food themselves for birds and animals.

However, invertebrates are declining in response to widespread habitat loss and fragmentation, changing agricultural and land management practices, development pressure, environmental pollution, non-native invasive species and many other factors.


One of the important first steps considering development and changes in land use is to ask what features of the site support invertebrates and what invertebrates are likely to be there. Brownfield sites may be havens for invertebrates.


It is not possible in this biodiversity plan to deal with all the groups of invertebrate, however we intend to have sections on butterflies, moths, and dragon / damselflies. In addition, two invertebrates are highlighted as priority species: the Glowworm and the White-Clawed Crayfish.


Butterflies: Over 30 species of butterfly have been recorded in Barnsley.
