Here's a great article on the problem of type conversion; when and how our native ecosystem gets converted to highly flammable weeds:http://www.latimes.com/news/local/la-me-greenhills2mar02,1,3479331.story?ctrack=1&cset=true
What does it look like? Something like this.
And fire is not the only thing that can cause type conversion. Anything that repeatedly clears the native chaparral plants from the landscape will do it. The photo above is from an area which was formerly grazed by cattle. The native chaparral was just beginning to move back in, but the plants were small and didn't have the roots to recover from the fires which burned through here in October, 2007. They certainly had not had time to build up their savings in the seed bank, either. So we're back to weeds. The chaparral plants will probably start creeping in again, but if this place burns again in a few years (which it will because of the weeds) then they'll be snuffed again. And so it goes with too much of our world.
