Page 3 April 23, 1991 Snyder Tree Planting Corrective Action Plan Dan Hernandez ROAD DISTURBANCE AREA #1: This is the largest of the disturbances. Grass cover is moderate to dense over virtually the entire area. In 1991 this grass growth will enter its second year and is expected to produce considerable top growth. The 26Q trees planted here had a moderate to wide spacing due t~~ the expected competition to occur from grass cover. Invasion of trees from surrounding areas will probably occur in the next five years, bait, unlike Williams Canyon, these invaders will not contribute significa~itly to reforestation for many years to come. Furthermore, five years fr~~m now the invaders will probably be much smaller than the survivors of this planting and distinguishing invaders from planted trees should tot present any problems. It is expected the final tree density will be at or slightly above the average for this side of the canyon. ROAD DISTURBANCE AREA #2: This is a steep site with limited so__1 depth. On this slope gradient, natural tree density would be expected to be well below the average for this side of the canyon. Ewen the forest on adjacent hillsides exhibits a noticeable decrease in densi~:y. Therefore, expecting this site to achieve the average would be unsupportable given the elope gradient and growth environment. Somewhat similar to Williams Canyon, this site is showing some signs of natural recovery. During the tree planting, numerous small pinyon pine and a few juniper seedlings were seen. These appear to tie two to three years old. On the average they were about 2" to 6" in height (1/10 to 1/Q the planted tree height). Whether this size differential will be maintained in coming years cannot be determined. But it is not impossible that the planted trees will exhibit Blow growth. If that were to occur, five years from now the two classes of trees might be difficult to distinguish. It is recommended inspections in future years anticipate such a pattern will occur. Because of the steepness of this slope it is highly recommended that inspections of this site be done from the roadside. Walking or climbing around on the site until after 1993 for ar~ything other than replanting trees, if needed, should be strictly avoided. Severe damage to the revegetation efforts could occur.
