Good management of these resources permits harvesting on a regular basis, whether the resource is timber, fish, deer, or whatever, without causing damage to the means of production.
Competent ranchers and farmers already do this, with neither overpopulation nor overharvesting. Good game and timber management does the same.
Not harvesting the available resources merely makes the existing resource base more susceptible to disease, infestation, or cataclysm (fire in timber, car accidents with deer, etc.)
The ecology is a dynamic system, and management must be dynamic also: capable of adjusting to conditions as they change. A dynamic system cannot be effectively managed with static rules.
No one-size-fits-all set of rules will be sufficient, and local control is the most capable of management vs bureaucrats in offices hundreds (or thousands) of miles away.
Right you are. The land will more or less always give back what you put into it in terms of planning and yield. That's what we all pray for, anyway.
Nobody I know of actively seeks to destroy the land. After all, we have to live on it, too.
