Woody plants; Herbicides. santa, golden fleece, deer-weed, rush rose, creeping sage, and brush seedlings (including chamise, Ceanothus, man- zanita, etc.). An appreciable percentage of the toyon was killed by the spray. In- terior live oak, coffeeberry, and redbud were not killed and would have to be treated by individual plant treatments (See Table A, p. 28). For successful aircraft application, spraying the first year after a burn may be necessary. By ground application satisfactory kills may be obtained the second year. This has advantages:

For successful aircraft application, spraying the first year after a burn may be necessary. By ground application satisfactory kills may be obtained the second year. This has advantages: (1) it allows time for the planted clovers to go to seed once and thus build up a res- ervoir of hard seed in the soil; (2) it gives more time for the germination of brush seedlings; and (3) it allows the perennial grasses to become better estab- lished so that they are less injured by the sprays. Encouraging the natural establishment of grass by spraying has an important bearing on soil erosion. Spraying will benefit grass seedings, whether these are made with annuals or perennials. Where fire and erosion are problems, sprays may be very important in converting chamise cover to a grass cover. Chamise may also be controlled along roads and rights of way, by methods described in Tables A, B, and D, pp. 28-36. Top: The brush in this area was knocked down with a bulldozer and burned. Area has not been seeded or sprayed. Note the abund- ance of sprouting brush and brush seedlings, as well as the absence of grass. (Hollister and Warren ranch.) Center: Chamise area com- pletely converted from brush to grass, with very little erosion following a reburn. The area was burned, sprayed, and reburned. Note the dense stand of resident annual grasses. (L. J. and George Gamble ranch, Knoxville, Calif.) Bottom: Chamise area following a reburn and subject to considerable soil erosion. Most of the chamise plants have once again developed sprouts from the burls at the base. This area should have
