FORESTRY QUARTERLY REPORT (July, August, September, 1986) 111/1 The major summer-early fall forestry activities include tree disease inspection and removal ; tree, shrub and flower maintenance; and evergreen transplanting. Tree Disease Inspection and Control This facet of the forestry program is intended to afford a control of elm and oak losses in Mounds View so as not to incur great losses in any one year. This allows an orderly removal of those trees diseased, lower costs are incurred during the process and valuable time is bought for replacement planting of different species. The "urban forest" in Mounds View thus retains its character and no one part of the City suffers undue aesthetic loss. In 1986, eighty-three (83) dead or diseased elm trees were identified and removed and 50 oaks were removed becuase of oak wilt. These figures are a substantial decline (40 percent and 33 percent respectively) from the totals for 1985. Tree, Shrub and Flower Maintenance This task required the assistance of forestry's temporary/full-time employee. Emphasis was given to the appearance of City Hall and Silver View parks in weeding flower beds and around trees, mulching newly-planted trees and plants in all parks and watering key areas when needed. The rainfall received during the growing season was both adequate and staggered to cover all but a part of early summer. The benefits of this rain to trees will linger for the next 111/1 couple of years. Evergreen Transplanting Late August to early September is a prime period to transplant evergreens. Any such trees not transplanted during the spring should best be moved during the spring should best be moved during this time to allow proper root set before winter. Using New Brighton's tree spade, six large pines and fir were moved to locations in City parks. Gypsy Moth Trapping Results • The Federal and State plant pest quarantine team has informed the City that no adult gypsy moths turned up In their intensive trapping scheme in 1986. This was good news considering the last two years had results that indicated the potential of a greater problem. The gypsy moth is a pest that in the larval (worm) stage will eat nearly anything green with a preference towards oaks. The project will revert back to a light monitoring level of trapping. Compost Site As in the past two years, the leaf composting site at Ardan Park will be open for grass and leaf clippings from October 10 to November 16. The finished, composted product has been in great demand. The City has been able to keep the space/leaf rotation since the start of the program. 111/1
