MEMO TO: MARY SAARION, DIRECTOR <br /> PARKS, RECREATION AND FORESTRY <br /> FROM: RICK WRISKEY, FORESTER <br /> I • <br /> DATE: JULY 28 , 1988 <br /> SUBJECT: QUARTERLY FORESTRY REPORT <br /> DROUGHT <br /> The drought of 1988 has been tough on trees and plants. Virtually <br /> all trees planted or transplanted during April and May of this year <br /> are stressed to the limit, even with periodic watering. Trees are <br /> being lost on exposed sites in parks. Most, however, are still <br /> alive on more moderate park sites. Suffering most are pines and <br /> spruce trees recently planted as well as all seedlings planted the <br /> last two years. <br /> Some large established shade trees on vulnerable sites on both <br /> public and private property have turned brown and dropped leaves as <br /> a result of 100 degree temperatures with hard south winds. Water <br /> and cooler temperatures will enable refoliation of these trees. The <br /> second set of leaves must be retained. <br /> SILVER VIEW PARKING LOT <br /> Curb protection for the fringe trees at Silver View Park is finally <br /> in place. Some of the adjacent trees will be lost however, due to <br /> root loss and subsequent hot weather. More suitable species <br /> selection will be chosen for replanting to better endure the <br /> conditions associated with heated asphalt. This planting will take <br /> place in 1989 . <br /> DUTCH ELM AND OAK WILT DISEASES <br /> Increases for both of these diseases are expected for 1988 . Current <br /> losses , however, are no more than 1987 . Increased fall inspection, <br /> because of the weather conditions of the summer will be necessary. <br /> Insect pests and other diseases of trees and shrubs have been <br /> favored by the drought and have prompted numerous calls to the <br /> forestry office for advice and assistance. These will be detailed <br /> in the year-end report. <br /> • <br />
