Leopold Defined Game Management “the manipulation of factors that limited population growth in game species”.
The limiting factor approach Game censusing - numbers and distribution Surveying population productivity - offspring Installation of refuges Controlled hunting - when, where, and how many Predator control - elimination Control of food and water availability Control of vegetation Planting, plowing, and burning Disease control- actually a function of predators
Leopold eventually grew to reject predator control not because it was ineffective, but because it was ecologically unsound

valuable lessons about people and their relationship with the land
Humans are part of the ecological community. “The disposal of private property to most land owners is purely a matter of expediency, not of right and wrong”
“In examining a question in terms of what is ethically and aesthetically right, as well as what is economically expedient. A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends to do otherwise”
Leopold’s Legacy A Sand County Almanac published in 1949 by Oxford Univ. Press. More than one million copies have been sold since, and only 20,000 before 1960.
