Initial results show that an average of 67% of the caterpillars are killed by parasitoid wasps and flies. A good result for the project, which investigates how to use natural enemies to keep the caterpillar under control.
Bird counts and nest box controls were also this year carried out at all test locations for tits. We found more different species in the nest boxes and the litter sizes were also larger than last year. In addition to many Great and Blue Tits, we counted 11 nests of the Pied Flycatcher.
