A genetic information system, based on performance testing of trees in metropolitan regions, is needed because of deteriorating environments and the coincidental dispersion of arboricultural specialists among many organizations. Arborists and nurserymen are being surveyed and several dimensions of metropolitan tree planting in 13 northeastern states have been defined. About 100,000 trees were planted annually from 1968-1972 along highways in this region and about 200,000 were planted by municipal agencies--together an annual investment of $12 million. Three maple species, two oaks, and honeylocust made up 54 percent of the planting. Appearance and adaptive characteristics as related to survival, health, aesthetic values, and maintenance are being determined.
