Berlin Recorded More Wild Bees in 2024 Than 2019
Mowing less frequently produced measurable results
Wild bee populations in Berlin increased 31 percent between 2019 and 2024, according to data from 200 monitoring stations. This contradicts the broader European trend of pollinator decline. The change happened after the city altered its approach to managing public green spaces.
What Changed in Maintenance
Mowing schedules shifted from every two weeks to every six weeks in parks and roadside strips. This simple adjustment let flowering plants complete their bloom cycles. Ecologist Ragne Veski documented which species returned first: mining bees appeared within one season, followed by leafcutter bees the next year.
The city also stopped removing so-called weeds from sidewalk cracks and building edges. These tiny habitat patches became surprisingly important. Camera surveys showed bees visiting crack vegetation more frequently than formal planted beds in some districts.
Critics said unmowed grass looked messy and would generate complaints. Surveys showed 68 percent of residents supported the changes once they understood the reasoning. The approach costs less than intensive maintenance, which helped secure continued funding through budget reviews.

How urban ecology shifts resource allocation
Cities investing in ecological infrastructure redirect budgets from reactive maintenance to proactive design. Green roofs reduce stormwater management costs while native plantings cut irrigation expenses. The distribution shows where funds flow when ecological thinking becomes standard practice rather than experimental add-on.
