Riparian Forest: Riparian Forest will be established by planting cottonwood seedlings at a rate of 200 to 250 bare root trees per acre. It is expected that the mortality rate of seedlings will be at least 50% and that should establish a final forest density of about 100 trees per acre. This density is on the high end for a mature cottonwood forest but this approach emulates the natural process of starting the cottonwood forest with a very high density and allowing natural competition to do the thinning. No grass seeding will be done where the trees are planted as that usually induces too much water competition and the trees are usually replaced by grasses. Invasion grasses will be relied upon to produce any grass cover in this zone. It is also important to control weeds for at least two years after planting. Periodic flood irrigation during the first year may also be helpful, especially if the soil tends to dry out during the middle of the summer. Irrigation of individual plants could be done, but with this high density planting it would be labor intensive and therefore quite expensive. Flood irrigation is more economical and effective. Only cottonwood will be planted. Due to the presence of abundant Russian Olive growth in adjacent forests, invasion of this species is expected. Russian Olive will be considered a weed and controlled accordingly. Russian Olive in bottomland situations is considered a severe pest and will not be allowed to become established in the Riparian Forest area or any other area. Shrub/Scrub: For the Shrub/Scrub zones, an emulation of similar areas should be created. Examination of such areas show a high dominance by willow. Tamarix, Pueblo East Pit Amendment Exhibit E Page 11
