Connectivity benefits most woodland invertebrate taxa but only in
landscapes with low woodland cover
Abstract
Woodland creation is crucial for nature recovery and achieving net-zero
goals. Although habitat creation to improve connectivity is assumed to
benefit biodiversity, this has not been extensively quantified across
multiple taxa and landscapes. Focusing on the UK, where woodland cover
is low (13%), we analysed species occurrence records from citizen
science for over 800 broadleaf woodland-associated invertebrate species
from 15 taxa in relation to woodland cover and connectivity. Overall, we
found that increased connectivity positively impacts the occurrence of
these woodland-associated species (effect of connectivity across
species, when accounting for the positive effect of woodland cover =
0.122). The benefits of connectivity varied considerably among these
taxa: 49% of species showed a significant positive effect, while for
7% it was significantly negative. Our findings emphasise the
biodiversity gains from increasing woodland cover and connectivity and
highlight the importance of spatial targeting and landscape context in
restoration efforts.
