Low vegetation boosted insect biomass and richness more than expected across German monitoring sites.

Key findings

50,087 insect OTUs (10,803 named species); low vegetation raised biomass 50–56% and richness 58% and 33%; land cover, weather, and climate explained 42% of site variation.

Methodology

Sampled flying insects with Malaise traps at 75 German sites in 2019–2020 and related biomass, richness, and turnover to land cover, weather, and protected-area status.

Limitations

Does not experimentally restore habitat or prove that protected-area designation caused the insect patterns.
