Technical Information Sheets are a FREE resource, and each report provides our WCISA members, arborists, tree care professionals, and the general public with concise, research-based knowledge on various aspects of tree care and urban forestry.
These sheets are designed to simplify complex topics, offering clear guidelines, best practices, and current industry standards. Documents serve as valuable reference tools, helping professionals stay informed about the latest developments in arboriculture while supporting healthy trees and sustainable landscapes.
Whether addressing pruning techniques, tree health, or pest management, our Technical Information Sheets empower individuals with practical and reliable information. The information will be particularly beneficial to arborists and tree-care professionals practicing in California, Hawaii, Arizona, and Nevada.
The following ten Technical Information Sheets, developed by Helen Stone and Dr. James Downer, address key topics relevant to arborists both within the WCISA region and beyond. Each sheet offers valuable insights and guidance on issues that matter to tree care professionals, providing expert knowledge and practical tips for a wide audience.
