Problems of human-wildlife interac- 
Lions in National Parks are described 
in this popular article. Park visi- 
tors unaware of the potential hazards 
of confrontations with wildlife some- 
times create dangerous situations by 
inappropriate behavior. Park visitors 
are entitled to wildlife viewing ex- 
periences, but must be educated about 
wildlife behavior and maintain respect 
for wild animals.

The reproductive history of 14 falcon 
eyries along the upper Mississippi 
River are summarized. From 1955 to 
1964 all known peregrine falcons dis- 
appeared from the study area; human 
activity increased very little during 
that time and is not considered impor- 
tant in the decline. One instance of 
disturbance to a peregrine eyrie by 
picnickers and rock climbers is men- 
tioned.

Environmental factors in relation to 
caribou movement and disturbance are 
discussed. Behavior of caribou in re- 
sponse to human disturbance is related 
to the evolutionary history of caribou 
and their adaptations to past non-hu- 
man disturbances. Management implica- 
tions are discussed in terms of habi- 
tat requirements and the adaptability 
of caribou to human disturbance.

The Indiana bat is the only listed en- 
dangered mammal still found in the 
wild in New York, Human disturbance 
seems to be the greatest threat to 
these bats. The state management plan 
for the Indiana bat includes posting 
and law enforcement with regard to 
critical habitat protection, and regu- 
lation of spelunking activities to 
certain areas and times.

soil and vegetation are discussed and 
management problems related to biolog-

vehicles are discussed. Unpublished 
data from recent Bureau of Land Man-
