Insect Habitat Creation and Welfare Benefits

Creating insect habitat in gardens, farms, and public spaces benefits insect populations and the broader animal welfare ecosystem they support. Evidence-based habitat creation maximises impact.

Key Facts

UK insect populations have declined by 60% since the 1970s in monitored species
Insect biomass decline reduces food availability for birds, bats, and other insectivores
Native wildflower planting provides higher-quality habitat than most exotic ornamental plants
Leaving grass unmown creates habitat for ground-nesting solitary bees and beetles
Log piles and dead wood provide essential habitat for over 2,000 saproxylic (wood-dependent) invertebrate species

Welfare Considerations

Insect habitat creation has cascading welfare benefits throughout the food web. The welfare of insectivorous birds — whose populations are declining due to food shortages driven by insect loss — is improved by increasing insect availability. The welfare of bats, hedgehogs, and other invertebrate predators similarly benefits from insect population recovery. Whether insects themselves have welfare significance remains scientifically uncertain, but the precautionary principle and the cascade effects on clearly sentient species both support prioritising insect habitat creation. Individual and institutional actions to create insect habitat aggregate to meaningful population-level benefits.

What You Can Do

Plant native wildflowers in any available outdoor space — even window boxes
Leave a patch of unmown grass for bees, beetles, and other invertebrates
Create a log pile or deadwood habitat feature in your garden
Reduce or eliminate pesticide use in gardens and advocate for the same on public land
Participate in insect monitoring citizen science projects to contribute to population data
