Effects of rural anti-coagulant rodenticides on non-target species - predatory birds - PN0927

Description
In the UK some incidents involving the death of Red Kites have been attributed to secondary poisoning by anticoagulant rodenticides. This and increasing evidence that residues of rodenticides are also present ina proportionof other avian and mammalian predators and scavengers such as barn owls, pole cats, stoats, weasels and foxes has lead to concerns that current regulatory procedures underestimate the risks to these species from the approved use of rodentcides.

This project consisted of a desk study using existing data to assess which species are exposed to rodenticides (when correctly used) and to what extent, and to assess the likley effects on avian predators and scavengers at the population level.
Objective
1. Use existing data to estimate the exposure of avian predators and scavengers and target prey to rodenticides as a result of approved use.

2. Assess the likely effects of current rodenticide usage on predatory/scavenging birds at population level.

3. Identify key factors affecting exposure and risk and identify areas where further information may be required.
