Are you telling me that the Native Americans in the Willamette Valley of Oregon didn’t periodically set fire to the Valley floor to improve grassland forage for big game? OSU Professors would disagree with your opinion.
In California, Oak Savannah is a more natural occurance. In the Willamette Valley, Oregon, the entire valley floor would be completely covered with swamps and scrub brush without human intervention. Roads would be (literally) impassible without machine brushing every 4 years minimum.
An OSU Professor (IIRC, Paul Adams of Forest Engineering) bought my first book and told me it was beyond their students' ability to read it.
Oh, and I even have a pile of Stipa pulcra and Elymus glaucus straw on top of the hill for an extreme vertex three variable factorial experiment the purposes of which include (drum roll please) observing the interaction between BURNING A NATIVE GRASS MEADOW with the introduction of mineral nutrients. This meadow, I am told by competent authorities, is perhaps the purest example of such a restoration on the entire North American Content. They were so blown away by it that I've been invited to publish for presentation before the California Native Plant Society Conservation Conference in San Diego this January.
So I'm so very glad to have you inform me; I'd have been lost without the depth of your experience.
