342-4 Plant stock at the same depth it was planted in the nursery, or slightly deeper. Do not plant stock shallower than planted in the nursery. Pack soil firmly around the roots of seedlings to make it difficult to pull the seedling from the ground. Eliminate all air pockets in the soil around the roots. Apply water to seedlings immediately after planting. Refer to the Colorado Tree/Shrub Establishment, 612 Conservation Practice Standard for planning criteria and specification requirements. Supplemental Water for Plant Establishment In low rainfall areas where water is available and rapid establishment is needed, irrigate newly seeded areas during the first growing season when rainfall is not adequate for plant development. Apply water at approximately one-week intervals at a rate of 0.75 to 1.0 inches per application. Apply water to woody transplants at the time of planting, followed by an application of at least one gallon per week applied to the soil at the base of the plant for the first growing season. Protection of Plantings Protect planted sites from trampling, grazing, rodents and browsing animals until plants are well established. In heavy use areas, protect critical area plantings with fencing or barriers. OPERATION AND MAINTENANCE Manage use of the area as long as necessary to stabilize the site and achieve the intended purpose. Control or exclude pests that will interfere with the timely establishment of vegetation. Conduct inspections, reseeding or replanting, fertilization and pest control to insure that this practice functions as intended throughout its expected life. Observe establishment progress at regular intervals until the practice has met the criteria for successful establishment and implementation. NRCS, CO November 2007 Where establishment of vegetation creates potential habitat for grass -nesting birds, consider the impacts of vegetative disturbance upon these birds and their nests and include them in the operation and maintenance plans. Do not conduct maintenance activities that result in disturbance of vegetation during the primary nesting season for grass -nesting birds, where occupied habitat for these species exists.
