Bentonitic, rocky, disturbed soils are quite inhospitable most seasons, but winter snows make them almost, a little bit, very nearly agreeable. In addition to moisture, many native species of forbs and shrubs also require a period of cold stratification in order to germinate.
Hubby tells me that his mine-farming efforts have been most appreciated by the local horned lark populace who have been happily availing themselves of their sudden windfall.
The jackrabbits don't seem to mind Hubby's intrusion into their home either, even allowing him within four feet. Perhaps they feel safer from the coyotes and eagles when men and machinery are out and about.
"To everything there is a season, a time for every purpose under heaven." ~Ecclesiastes 3:1 (NKJV)
