Thanks.
I note that there is plenty of information about landscaping around houses for fire protection of houses in California.

As I recall, if heavy rain follows wildfires in California, there are mudslides. There is no information on which nonflammable plants prevent soil erosion or which will crowd out flammable weeds. Apparently the CA government doesn't want to take its own advice on public land. Somehow, it is the homeowner's responsibility. The government plants new trees in burned forests, thereby, perpetuating the problem.
