Photos from October Tree Risk Assessment Workshop

The PNW class “Common Fungi Affecting PNW Trees and Implications for Tree Risk Assessment” was a classroom/outdoor course in tree diseases, and particularly anyone conducting risk assessment of trees with disease.  Led by Dr Julian Dunster and Professor Bob Edmonds.

The diseases covered included Phaeolus schweinitzii, Heterobasidion occidentale, Armillaria ostoyae, Porodaedalea pini, Kretzschmeria deusta, Phellinus sulphurascens, Neofusicoccum arbuti and others.

Morning lectures covered visual assessment techniques for disease, using a combination of signs and symptoms of common diseases in native PNW trees. Sonic tomography and resistance drilling will be discussed as examples of advanced risk assessment techniques.

The afternoon was spent outdoors examining diseases of Douglas-fir, western hemlock, western red cedar, bigleaf maple, and Pacific madrone. The types of wood decay, fungus fruiting bodies, as well as structural and risk implications will be covered.

The PNW is grateful to have Roger Barnett attend, to learn and capture moments on digital film for all to take a peek into this course.  Please see some of these moments on this flicker account below:
