  1. Forest Health Technical Advisory Committee
    First meeting of Forest Health Technical Advisory Committee begins process to recommend treatments on health of forests.
    Responding to worsening forest health conditions, the committee will advise the Commissioner of Public Lands on areas of potential geographic priority and potential remedies and actions.
    The Committee’s recommendations and local input from landowners will help determine what actions are needed, such as forest health treatments and whether a Forest Health Hazard Warning is necessary.

  2. 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. Click here to read.

  3. Don't Move That Firewood!
    Protect the Nation's Forests this camping and hunting season, get your firewood from a vendor close to your destination. Ask if each piece of firewood is free from invasive insects and diseases. Don’t pack in your own, unless you know for a fact that each piece is free from invasive insects and diseases!
    Invasive insects and diseases in dead and dying wood threaten our native trees and forests. When you move firewood, you could be giving these pests a free ride to new territory and their new home.
    Just one example of a pest moving in firewood is the emerald ash borer (EAB), a destructive, invasive insect from Asia. EAB is responsible for more than 20 million dead and dying ash trees and millions of dollars in damage in Michigan, Ohio, Indiana, Illinois, Pennsylvania and West Virginia.
    For information on this and other forest pests that spread in firewood, read the proceedings of the 2008 Firewood Forum. Click here to read .

  4. Don't Move That Firewood!
    Please protect the Pacific Northwest from invasive species by obtaining or purchasing your firewood at or near your camping destination (within 50 miles). Firewood can carry insects and diseases that threaten the health of our western forests. You can make a difference by buying and burning your firewood locally.

  5. 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.

  7. 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.

  8. 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.

  9. 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 another member by clicking on our Membership Form,
    and printing out the form and then send it in with your membership dues.

  10. Our motto might be:
    We are trying to decide upon a good working motto for our corporation.
    So far one of this seems to fit. What do you think?
    1. Working together we can stomp out tree diseases!
    2. Working together to help the trees of our forests, homes, and farms to live better lives.
    3. Working to help our trees to live better lives.
