Newly created grassland habitats designed to offset nature lost to development can effectively support wild pollinators, according to a first-of-its-kind study in the Netherlands published in the Journal of Applied Ecology. The research focused on bees and hoverflies, key species for ecosystem health.
The findings offer promise for biodiversity offsetting, a practice where developers restore or create habitats elsewhere to compensate for environmental damage. This approach has faced skepticism, but the study suggests it can work for certain insect groups when properly implemented.
Lead researchers tracked insect populations across new and established grasslands. While specific numbers were not disclosed in available sources, they reported that the created habitats attracted diverse pollinator communities comparable to natural sites.
The study's authors caution that results may not apply to all species or regions. Further research is needed to assess long-term effectiveness and to determine optimal design of compensatory habitats.
Conservation groups welcomed the evidence but stressed that offsetting should complement, not replace, protecting existing ecosystems.
