<br />8 <br /> <br /> <br />Climbing and pruning practices shall not injure the tree except for the pruning cuts. <br />It is best to clearly identify a pruning objective and then select the pruning type most suitable to <br />achieve that objective. For example, if the objective is roadway clearance, crown raising would <br />be the selected type of pruning. <br /> <br />D. Tree Care for Birds and Other Wildlife <br />Birds and other wildlife have strong associations with trees and provide ecological and other ben- <br />efits. Tree and landscape care can be impactful to them, especially during the nesting sea- <br />son. There are several federal and state laws and regulations pertinent to wildlife and the tree <br />care and landscape industry. The Federal Migratory Bird Treaty Act and CA FWS 3503 are the <br />most relevant to tree care in the urban landscape. Tree and landscape city staff and contractors <br />should be trained and comply with all relevant regulations and best practices to reduce impact on <br />wildlife. The Tree Care for Birds and Other Wildlife Best Management Practices of the Western <br />Chapter of the International Society of Arboriculture shall be a guiding document for policy and <br />management of trees all year. <br /> <br />E. Plant Health Care Plan and Integrated Pest Management <br />It is recommended that Agencies fund the development of a comprehensive plant health care <br />program to serve as a guide to manage the health structure and appearance of plants and trees <br />in the landscape. As part of that plan, there should be an Integrated Pest Management strategy. <br />This strategy is a method of controlling plant pests by combining biological, culture, mechanical, <br />physical, and/or chemical management strategies. The Integrated Pest Management strategy <br />should be constructed based off the Integrated Pest Management Flowchart (Appendix B). The <br />Integrated Pest Management Flowchart is based off ANSI A300 standards. The flowchart will <br />dictate the plan of action when there is an identified plant health concern. <br /> <br />If action against pests is warranted, always consider treatments as part of an overall plant health <br />care program. The pest source shall be identified and targeted with a specific and timely <br />treatment. All prescriptions for pesticides are to be issued by a Pest Control Advisor (PCA) per <br />the Department of Pesticide Regulations. Additionally, applicators must be licensed or certified to <br />apply. If it appears that insects or disease may lead to the death of a public tree, then it is the <br />responsibility of the city to evaluate the condition according to the following guidelines and treat <br />the problem in a timely fashion to prevent further decline of the tree. <br />1. For treatment of insects, the pest control advisor shall be consulted. Nontoxic <br />materials shall be used whenever feasible. All chemicals must conform to the <br />California Department of Pesticide Regulations. <br />2. For disease and decay that erodes the health or weakens the structure, further <br />analysis by an arborist may be required to evaluate the stability. <br />3. Diseases below ground are often caused by poor landscape design surrounding old <br />trees, which encourages harmful and often lethal ailments. The following conditions <br />favor disease: <br />a. Compacting of the soil within the tree’s dripline <br />b. Removing soil from the tree root area <br />c. Planting incompatible plants within the tree’s dripline <br /> <br /> <br />Section 3: Routine Tree <br />Maintenance (continued)
