This report updates an earlier edition 
describing the social and environmen- 
tal effects of off-road vehicles, par- 
ticularly snowmobiles. A section on 
fish and wildlife effects reviews lit- 
erature describing harassment of wild- 
life, and legal responses to adverse 
impacts of off-road vehicles on wild- 
life. Policies for control of envi- 
ronmental impacts are suggested.

University of Wisconsin Press, Madi- 
son. 
A recent lack of observations compared 
to earlier indications of abundance 
suggests that peregrine falcon numbers 
in Mexico have declined. Possible 
causes of the apparent decline include 
harassment and killing of peregrines 
by local fishermen and tourists, and 
other possible human disturbances.

Mountain goat-human interactions in 
Glacier National Park were character- 
jzed as goat approaches to people and 
human approaches to goats. Attract- 
ants causing goats to approach people 
were identified, and overt aggressive 
behavior of goats toward humans noted 
in less than 5% of goat approaches.

Goats generally approach people re- 
maining quiet, but are frightened by 
sudden movements or appearances of 
people. Management recommendations 
are presented.

University, Fort Collins. 116 pp. 
A study of black bears in Yellowstone 
National Park found that backcountry 
and roadside areas were utilized by 
two separate populations. Bearproof 
garbage containers affected bear use 
of campgrounds but not of roadside 
areas. Artificial food was the most 
important diet constituent of roadside 
area bears. Most black bear-human in- 
cidents occurred in campgrounds.

Analysis of data collected for the 
North American Nest Record Card Pro- 
gram, Cornell University Laboratory of 
Ornithology, revealed influences of 
human visitation on nest mortality 
rates for five species of birds. The 
data indicate a need to prevent preda- 
tors from following human trails to 
bird nests.
