<br />become established in the first year without excessive moisture competition <br />' from the grasses. <br />' No irrigation or shingle protection is considered necessary to establish <br />the trees. On the Visual Berm 450 bare root stock trees and shrubs ,vere <br />' planted. No irrigation or protection was provided and only one fertl.fizer <br />tablet was placed in the planting hole. After 6 years, approximately 60% <br />' of the original planting is still alive and all but a half dozen or so are <br />strong, healthy plants, some having reached heights oP nearly a feet. <br />Those areas are east facing whereas this area is north facing. It is well <br />' documented that tree growth, keeping species constant, tends to be <br />strongly controlled by aspect. This is only marginally true of grasses, <br />' (orbs, and most shrubs. <br />' Fertilization oP the trees will be limited to the inclusion of a fertilizer <br />tablet In the bottom of the planting hole. It Is also possible a small <br />' amount of polyacrylamide will be included with the planting to help <br />counteract the effects oP dry periods, but this may be limited to only sites <br />where dryness is expected. <br />PolyacrylamIdes show considerable potential for use in revegetation, <br />i ' particularly in the elimination or reduction of a need to use irrigation. <br />However, the verdict is still out as to exactly how useful it is in plantings <br />' on semi-arid ]arid. Castle Concrete has already initiated some literature <br />and hydrating studies of this material. <br />' SEDIMENT BASIN AND OTHER RELATED DISTURBANCES: 'Che <br />revegetation oP these areas which Include the sediment basin, smaller <br />' roadside disturbances, and various other features will be done as each area <br />is completed with use. In the case of the sediment basin seeding of the <br />' disturbed areas around the basin which will not be In the pond area or <br />further utilized will be accomplished when construction is completed. <br />' Once the sediment basin is no longer needed when the operation is <br />completed the area will be completely revegetated using the seed mixture <br /> <br />is <br /> <br />
