Members of 261 insect families were found in the study area, of which 220 were collected in this survey. Damage surveys showed great variation in the rates of insect attack on dominant plant species

Representatives of 50 insect families were collected in sweep net samples, and additional families were observed to be present on the Suncor dike. Insect attacks were severe on conifer trees

Biomass of insects collected averaged 0.82 g oven-dry weight m-2, and ranged from 0.28 (Jack Pine forest) to 3.11 (fen) grams. Use of insects as environmental monitors is discussed

Climatological analysis of recent data from the MAPS network of automatic meteorological data acquisition, forestry lookout stations, minisondes, pack surveys, and the Fort McMurray station

Wood frog (Rana sylvatica) was the most abundant and widespread species in 20 sites examined. Boreal chorus frogs (Pseudacris triseriata maculata) and Canadian toads (Bufohemiophrys) found at

Control rodent damage by: (1) Planting trees and shrubs when rodent numbers are at the low or declining phase of their cycle, and (2) Manipulating rodent numbers by manipulating vegetative cover.

Physical changes evident at tributary confluences were Secchi visibility, current velocity, and flow direction. At the tributary mouths, sand and silt substrates were predominant in sheltered areas

50,170 Albertans engaged in nonconsumptive fish and wildlife use in the AOSERP study area for a total of 83,393 recreation days during 1975-76.

Population growth in Fort McMurray (from 1200 people to 25,000) necessitated the institution and continuous expansion of a service delivery system, including urban infrastructure and social services
