@Alaskan I know your degree is in Range land management... Does it differ from climate to climate?
Here we are semi Arid.... leaning toward arid these days. I am watching Trees of all kinds die from the drought.... Eucalyptus cover a broad spectrum of needs They tend to kill off the underbrush as they grow the oils in the leaves are toxic enough to allow the tree to stake its claim to the soil. They are especially drought tolerant and pest resistant... So when they get under stress they do dramatic things. Like drop off Whole branches weighing enough to kill. They are not native but we have huge groves of them planted by the Railroads in hopes of using them for Ties.... and of course they naturalized immediatily ... They type of eucalyptus they planted were useless for the job they wanted them for.
Our trees are Scrub oak and in the mountains we have a few Decidouous oak scattered about and Conifers. in low areas where stream beds are or the water is easy to reach deep down there are Sycamores and willows too.
Here are grass lands are fire dependant... Wild Oat grass is the easiest to spot when on a drive... Its the first to come back after fire. Right now is our Green season which lasts as long as the rain. About the time the snow is beginning to disappear in other areas our hills are turning yellow...
For what its worth I have been told in areas that can support cattle it takes about a hundred acres. none of the ranches I know of irrigate their pastures so Feed is grown in the deserts of Imperial county...
Historically many areas of San Diego county were settled by Basque people Sheep did well in the Chaparal. You can still see the changes they made to the ecology even though they are long gone.
