Van,
Re:
Let me add something to your definition, if I may. Overgrazing is placing cattle on land that will not sustain them without adding supplemental feed. By your definition, all feedlots are overgrazing, since the cattle would not survive without the feed they are getting.
You are absolutely correct. Agreed.
Re:
I have to disagree with the "knowingly" part. Pasture that is overgrazed is still overgrazed, whether it is on purpose or out of ignorance or whatever.
You are correct again.
Re:
I also disagree that "most all other circumstances are out of managements control". I believe most things are in his/her control, at least to a degree, weather being one of the biggies that isn't. Just my humble opinion.
Now here is where we start to part ways.
Re: "I believe most things are in his/her control"
There are only three elements that can cause overgrazing besides actual poor management and they are:
1. cattle
2. weather and
3. the land ( soil and topography)
Now Re: "I believe most things are in his/her control,"
I disagree as I don't know anyone who can control/change the weather, or the topography, and/or the soil type for a specific geographical location.
And that only leaves the cattle under management's control.
What else do you see as being under managements control unrelated to the above three?
What some of you people don't seem to comprehend is that most of TN and GA pastures are not really pastures yet.
Most of the land we run cattle on is virgin land. It has not had 200 years of nurturing and it is far from "pristine" that you all are visualizing. It is cleared clear cut and burned harvested timer land.
And if it is not used it will revert back to scrub over growth and become totally useless to anyone.
Now before you even mention fertilizer and lime let me tell you this.
The soil in this area will not hold fertilizer or lime.
You can put it on and the first good rain you can stand on the bank of the TN River and wave goodbye to your fertilizer and lime dollars.
Now until we can build some humus in this soil and deepen the top soil (about 100 years) by running cattle on it, at certain times of the year, or weather condition, what you'll are calling overgrazing will occur, as will erosion. And some of both will be intentional.
But that does not mean the cattle will suffer (not be sustained) in any way as the cattle are the driving force behind the whole operation.
