Authored by Nelda Matheny, Larry Costello, Carol Randisi and Ryan Gilpin. This Guide is a tool to help landscape owners, designers and managers use recycled water effectively and successfully in San Francisco Bay Area landscapes. It is designed to help you understand the basic components of how to evaluate site conditions, adjust existing landscapes, design new landscapes, and care for landscapes irrigated with recycled water. Many people and organizations were involved with the development and review of a larger body of work that has been summarized and condensed into this Guide. The original review team included landscape professionals, scientists and water engineers and managers.
The Guide is available as a free download with an optional donation of $20.00 to The Britton Fund to further support science-based research for professionals in the West. Download the Guide here.

Tree Care for Wildlife Best Management Practices – 2022 Edition
Authors: Corey Bassett, Kara Donahue and Ryan Gilpin. Tree Care for Birds is a program of the WCISA. This document provides essential guidance for the tree care and landscape industry on minimizing impacts to wildlife and managing habitats during tree work. With many species in decline due to habitat loss, the role of urban foresters in creating and maintaining habitats is crucial. Most tree care professionals aim to act responsibly, and this document offers a framework, including regional examples from Arizona, California, Hawaii, and Nevada, to help minimize wildlife impacts. While compliance is voluntary, these Best Management Practices (BMPs) are designed to support wildlife conservation and help professionals navigate complex federal, state, and local regulations without imposing new rules.

Wildlife Habitat Snag Signs
Not all dead trees are hazards—some are vital wildlife habitat. These signs help arborists and land managers communicate that select dead or dying trees are being thoughtfully preserved for the benefit of birds and other wildlife, not removed for aesthetic or health reasons. Provided by the Tree Care for Birds Committee and WCISA, these signs support responsible habitat management while acknowledging that each tree decision is site-specific.
