INTRODUCTION
Laminated root rot (LRR) is a fungal pathogen, Phellinus weirii, also known as yellowing ring rot. (LLR gets its name from the lamination of the decayed wood (see photo above). This fungus is widespread in Southern British Columbia, Washington, Oregon, northern California and western Montana.). It is one of the most damaging root diseases amongst conifers, especially firs and cedars, in the Pacific Northwest. Douglas fir, Mountain hemlock, Western hemlock, Grand fir, and Pacific silver fir are highly susceptible to infection by this pathogen. Pine species like Western white pine and Ponderosa pine and larch are more resistant to it while hardwoods are immune. The fungus was first discovered in 1914, on Western red cedar in Idaho. The first reported case in Douglas fir was in 1940, at Cowichan Lake, British Columbia.

BIOLOGY
The mycelium of LRR doesn’t grow in the soil and the spores do not spread by wind like most fungal pathogens. Infection occurs when roots of healthy trees grow in contact with infected roots.

After initial contact with a living root, the mycelium grows on the bark, extending only a few inches into the surrounding soil. The mycelium penetrates the host through the injured bark and advances along newly infected roots. Symptoms include crown yellowing and thinning, distress of cones, red-brown staining of outer heartwood, and separation of annual rings. Less discernible is the root rot which eventually decays the roots, destabilizes the tree, and leads to death and toppling. In addition to the loss of mature trees within a stand, LRR creates potential hazards from tree fall especially in small urban parks. The number of cases of the LRR disease has increased substantially with the presence of fire suppression and resulting dominance of Douglas-fir and Grand fir.

The state has awarded a $523,000 grant to fund improvements at Nadaka Nature Park in Gresham’s Wilkes East neighborhood.

"It is unbelievable," said Lee Dayfieid, who cried, laughed and screamed when she heard the news last week that the park, through its partnership with the city of Gresham, won the $523,480 grant from the Oregon Parks and Recreation Department.

The money means that the little-known and once-neglected forested area in the middle of the city can become a full-blown neighborhood park complete with community gardens, a nature-based play area, picnic shelter and improved walking trail.

You'll find plenty of root vegetables, braising greens and lettuces, and of course plant starts for your own vegetable garden.

Bring your reusable shopping bags and plenty of small bills, though some of the markets will trade you a credit/debit card for wooden tokens that all vendors accept, which can be easier to handle than cash. We've indicated those markets that accept EBT or other food assistant coupons.

Aircraft traffic to increase over Wilkes East during summer airport construction

Aircraft traffic to increase over Wilkes East during summer airport construction. Info here!

Get ready for another summer of increased air traffic as PDX airport runway construction resumes, again

Work is planned to reconstruct Taxiway C and repair the south runway this spring through fall 2013 at Portland International Airport (PDX).

Planned is the full reconstruction of the eastern portion of Taxiway C, which provides aircraft access to and from the south runway. The south runway repair will replace concrete that was damaged after a military jet’s tire failed, causing its landing gear to scrape the runway. Temporary repairs are already in place.

Taxiway C reconstruction work will run from April 1 through mid-October. Repairs are planned for the south runway from approximately April 15 to May 31, and again from August 16 to September 29. The runway will be open between June 1 and August 15 to help accommodate peak summer traffic.

While no major flight schedule delays are expected, airport neighbors should expect increased flights over some airport neighborhoods during the south runway closure.
