Cook Endowed Chair Ian Burke, University of Idaho Weed Science Principal Researcher Joan Campbell, and Oregon State University Scientist Judit Barroso.
Designated Forestland in Washington State (FS388)
Designated Forestland (DFL) is a money-saving property tax assessment option for qualifying forest landowners in the state of Washington. This publication is intended to help small forest landowners in Washington better understand DFL, including how it works, potential benefits, eligibility requirements, and more.

Use of Probiotics in Pacific Oyster and Manila Clam Aquaculture (FS387E)
Shellfish, like any farmed livestock, can harbor pathogens harmful to people and shellfish. Adding beneficial microorganisms to shellfish water as supplemental feed has been proven to bring health benefits and reduce disease-causing organisms. Learn about the ongoing research taking place in Oregon and Washington in this guide by WSU Cranberry and Shellfish Extension Specialist Laura Kraft, Oregon State University Professor Christopher Langdon, and Vancouver Island University’s Timothy Greene.
Revised guides
