WildPosh
Pan-European assessment, monitoring, and mitigation of chemical stressors on the health of wild pollinators

Wild animals and plants are exposed to increasing environmental pressures. Pollinators such as wild bees, butterflies and hoverflies are particularly affected. The spread of pesticides poses a major threat to them. WildPosh is a joint research project that aims to better understand the effects of pesticides on wild pollinators and improve their health and pollination performance in Europe.
Objectives and methodology
Since chemical exposure varies depending on the region, cultivation system and pollinator species, we are investigating pesticide exposure in four European countries with different climate zones: Germany, England, Estonia and Spain. We conduct field studies, test the effects of pesticides in laboratory experiments, and collect data on pollinator species and their traits, as well as the toxicity of pesticides.
The main objectives of WildPosh are:
- Determine the real-world agrochemical exposure profile of wild pollinators at landscape level, within and among sites
- Characterise causal relationships between pesticides and pollinator health
- Build an open database on pollinator traits/distribution and chemicals to define exposure and toxicity scenario
- Propose new tools for risk assessment on wild pollinators
- Drive policy and practice
Work packages (WP)


The team at the Chair of Nature Conservation and Landscape Ecology is significantly involved in WP1 and WP2 and is investigating, among other things, the effects of pesticides on wild bees in laboratory and semi-field experiments.
