Wild fauna and flora are facing variable and challenging environmental disturbances. One of the animal groups that is most impactedby this, concerns pollinators. Pollinators face multiple threats, but the spread of anthropogenic chemicals (i.e. pesticides) form a majorpotential driver of these threats. WildPosh is a multi-actor, transdisciplinary project whose overarching mission and ambition are tosignificantly improve the evaluation of risk to pesticide exposure of wild pollinators, and enhance the sustainable health of pollinatorsand pollination services in Europe. As chemical exposure varies geographically, across cropping systems, inside the crop system andamong pollinators, we will characterise exposure by doing fieldwork in 4 countries representing the four main climatic European regions,Mediterranean, Atlantic, Continental and Boreal climate in Germany, England, Estonia and Spain. We will also develop experiments incontrolled conditions on different species of bees, syrphid flies, moths and butterflies, and collect in silico data on their traits and ontoxicity of pesticides. With WildPosh, we aim to achieve the following objectives: 1. Determining the real-world agrochemical exposureprofile of wild pollinators at landscape level, within and among sites; 2. Using integrated and controlled laboratory and semi-fieldexperiments to characterise causal relationships between pesticides and pollinator health; 3. Building an open database on pollinatortraits/distribution and chemicals to define exposure and toxicity scenarios by developing databases on ecological traits and the spatialdistribution of pollinators in relation to their potential exposure to pesticide; 4. Proposing integrated systems-based risk assessmenttools for risk assessment for wild pollinators; and 5. Driving policy and practice through interactive innovation, meeting the need formonitoring tools, novel and innovative screening protocols for practice and policymaker use.
