- Looking at the Future of Washington Forests:
Growing concern for Washington’s forestlands prompted the state legislature to authorize a major study called “The Future of Washington Forests.”
The State of Washington Department of Natural Resources contracted with the University of Washington’s College of Forest Resources to prepare a
comprehensive report assessing topics such as the competitiveness of Washington’s timber supply, conversion of forestlands to urban development,
and forest health. The project also relied on the participation of stakeholders to produce a set of policy recommendations for the legislature.
The results are now available in The Future of Washington Forests 2007 Report to the Legislature.

- Noninfectious tree diseases are those caused by nonliving agents. This type of disease is not transmitted from one plant to another.
Extremes in temperature and water supply are the most common causes of this type of disease. Other causes are chemical substances in the soil, water,
and air; transplant shock; and mechanical injuries. These nonliving disease agents are a major cause of loss in forest and landscape trees. Often
they weaken the tree, enabling living agents such as fungi, bacteria, viruses, nematodes, and insects to attack and further injure or kill the tree.
These living agents may build up on trees weakened by noninfectious agents and threaten the health of nearby trees.
Superficially, the symptoms of noninfectious diseases may resemble those produced by insects or fungi. If no signs of these organisms are present,
the tree may have been affected by one of the agents described here. Even if signs of fungi or insects are present, a nonliving agent may be the
underlying cause of your tree's problems. In most cases, prevention is the key to minimizing injury.
- I want to call your attention to this outstanding book on tree diseases.
Diseases of Trees and Shrubs, by Wayne Sinclair and Howard H. Lyon. This large hardcover book contains 660 pages. This second edition was published by
Cornell University Press November 2005.
This important comprehensive book has become a standard reference for plant health specialists, plant diagnosticians, horticulturists, arborists,
foresters, and their students. Now thoroughly revised, fully updated, and illustrated with more than 2200 digitally optimized color images in
261 full-color plates and more than 350 black-and-white photographs and drawings, this second edition is an unrivalled survey of the diseases of
forest and shade trees and woody ornamental plants in the United States and Canada. The book is both an authoritative reference book and a powerful
diagnostic tool. Organized according to type of disease-inducing agent, the second edition is also designed to be helpful in classroom and field
instruction. Symptoms, signs, and cycles of hundreds of diseases are described and microscopic features of many pathogens are depicted in photos
and line drawings. A searchable CD-ROM included with the book contains bibliographic entries for more than 4500 works that readers can consult for
additional information or images.

- We are looking for several qualified persons to serve on our board of directors. We need people that know a lot about tree pathology and
forestry insect problems and are dedicated to finding solutions and cures for helping our forest trees to overcome these problems with insects
and finding better ways to control and eradicate the diseases that plague our forests.
- We are also looking for additional persons to become members to help support our mission. We need both active members and members that can
support us now with their donations, and may be available later for projects and events.
Demonstrate your environmental commitment and become a member now by clicking on our Membership Form, and printing

- Our motto might be:
We are trying to decide upon a good working motto for our corporation.
So far this one seems to fit. What do you think?
- Working to help the trees of our forests to live better.
