Revegetation is the science- art- craft of establishing desirable plants in a disturbed area. In our part of the world, the Southwest, that usually means seeding grasses or wildflowers. They are what work best here with a minimum of long term maintenance.
Erosion control, weed prevention, wildlife habitat, aesthetics, and dust abatement are all reasons you might want to revegetate. County requirements or local building codes are also reasons to reseed.
There are a number of ways to get seed on the ground for revegetation projects, however, there is no single “best” way to seed. Every job is different based upon what kind of shape the ground is in. Looking to see if the soil is loose or compacted, flat or sloped, covered with weeds, and deciding what the eventual goal of the reseeding is, can help to figure out the best way to seed for that particular site.
There is one undeniable truth about revegetation: no matter what broadcast method is used, if there is not enough moisture nothing grows. Moisture is the key for successful plant establishment. The good news is that native seed is very tough and will stay in the ground for years, if necessary, waiting for the right conditions to germinate.
Below are a couple of articles that were written to deal with reseeding specifics. If you want more information on reseeding in this part of the world, there is a whole chapter covering it in "Just Add Water".
