The project recognizes that existing and continually emerging invasive tree-pests sometimes impact the quality of urban forests and ultimately, the welfare of wildlife. Evaluation and management of such pests is considered standard practice in arboriculture. It is does not fall within the scope of this project. To learn more about what urban forest managers are doing to reduce the impacts of pests and disease visit the Agriculture and Natural Resources page on the University of California website.
No. These are recommended practices that are designed to help keep arborists from breaking the law. While we think that they are a good way to avoid nesting wildlife, other methods for minimizing impacts to wildlife may be just as good.
We have had good luck with a web search for “consulting ecologist (city name)”. We are working on developing a list of wildlife professionals and Audubon Chapters that are available to assist arborists. If we are successful, this list will be available under the Articles and Links for tree care professionals.
No. The Best Management Practices were developed by a group of arborists, wildlife biologists, and wildlife advocates that formed the grassroots organization Tree Care for Birds. Many ISA certified arborists were involved in its development, but it is not an official ISA document.
Wildlife Biologists can be expensive, but they probably won’t be needed very often. Mistakes with wildlife can be costly and it may be less expensive to pay a Wildlife Biologist than to pay fines and have negative public relations from a wildlife incident. In most cases, the cost of the wildlife biologist can be passed on to the property owner and shouldn’t be paid by the arborist
Be aware of wildlife every day, even in urban areas. Local Audubon chapters offer many free walks and for-fee classes to learn and appreciate birds and wildlife. Many people learn birds with a good bird identification book and a pair of binoculars.
No. We expect that only a few jobs would fall into the Category 3 where a Wildlife Biologist is recommended and that most of those jobs could be delayed to fall outside of breeding season. For Category 3 jobs, we recommend a wildlife biologist but each arborist must decide whether or not to work with a wildlife biologist.
No, these Best Management Practices are adding no regulations to the industry. The laws and regulations listed in Appendix III have been present in California for many years (nearly 100 years in the case of the Migratory Bird Treaty Act). The Best Management Practices help clarify the existing laws and regulations and provide guidance for how to work legally within these laws.
