Testing fladry as a nonlethal managementtool for wolves and coyotes in Michigan

Results have shown that fladry may be an effective temporary management tool for discouraging wolves from using livestock areas but labor and equipment costs may be substantial for large farms. Fladry was not effective in deterring coyotes

Evaluation of damage by vertebrate pests in California vineyards and control of wild turkeys by bioacoustics

Conclusion

• Wild turkeys caused damage in California vineyards by stripping berries from the clusters. Many growers believed that turkeys were the culprit for damage to their vineyards, but video recordings indicated otherwise. The video recordings showed that many other vertebrate pests were to blame. Turkey damage was observed in several vineyards but the problem was inconsistent with both areas and years. Broadcast calls did not work at all. The best deterrent that they found was netting around the perimeter of vines and the use of dogs. ATV patrols and hunting is also a good deterrent to keep turkeys out of vineyards.
