-3- Leaf miners, specifically birch leaf miner, did enough damage during the spring to warrant concerns of long range effects. I 4111 believe residents should be continuously advised of the perils of birch stress, be it insect induced , weather induced or a combina- tion of the two. The end result is always the same : decline - bronze birch borer - death of tree . , • On a less damaging note , numerous reports of the relatively harm- less Cecropia moth caterpillar were registered. While the five- inch worm stage feeds heavily and appears formidable , the host plants rarely incur damage and the beautiful moth that results more than justifies letting nature run its course in regards to this insect. FLOWER BEDS AND PLANTING About. 1 ,800 flowers were planted in beds around City Hall. Spe- cies compositions of salvia ( red) , marigolds (orange) , begonias ( red and white ) and impatiens ( red , white and orange ) created a pleasing color scheme at entrance and side beds. White allysum in the Mounds View bed fronting Highway 10 was exposed to an afternoon sun that was too severe . A suitable , more durable re- placement will be researched for 1984 trial . Additionally, in- creased weeding and maintenance of the front entrance beds is planned. A separate project of 1 ,500 red oxford tulips were planted in the 4111 timbered area north of Silver View pond. It is hoped that these will result in a welcome touch of spring color for path and park users. The bulbs will be left in the ground and assuming proper drainage and moisture content, will be viable for three to five years. SILVER VIEW TRAIL PLANTING A total of 141 trees were planted in and around the chipped path constructed at Silver View Park as part of the PRAD grant. Of interest was the opportunity to use some different species not normally planted in the course of a growing season . In all , some 19 different species were planted including such hardwoods as paper and river birch and black and autumn purple ash. Four types of conifers were planted , Colorado spruce , Austrian pine , Black Hills spruce and tamarack. As soil conditions in the park itself do not, by my estimate , lend themselves to optimum growth conditions, spacing of some of the above-mentioned trees will appear to be closer than in areas where peak growth might be expected. The exception to this would be in the natural , undisturbed "peat" areas where those of the water tolerant species should thrive with great vigor. 4111
