We do not normally use fertilizers and never use pesticides or herbicides.Ģ1. Over nitrifying soil layers produces insect attracting vegetation and invites invasives that can destabilize habitat values. Chemical Use: limited use of slow release, 5-5-5 fertilizer should be restricted to early and mid growing season only. Watering should take place in the morning to avoid mid day thermal shock.ġ8.
Hand or sprayer watering is less efficient than drip hose irrigation. Once indigenous growth has been established, drought will be a factor in selecting sustainable vegetation. Limited Watering: during the first growing season, limited watering may be necessary in times of drought, to support survivability. Fruiting vegetation planted upslope encourages down slope reseeding.ġ7. Plantings: growing season specifics and adjacent habitat mix should guide plantings. Over covering blocks sunlight and may redirect rainwater.ġ6. No Not Overload Top Cover: top cover protects survivability by providing additional thermal and moisture stability. The Cape's slopes often reflect glacial compression of soil materials rather than the expected angle of repose for compositional materials.ġ5. On Cape Cod, we have successfully used steep slope stabilization principles for sand/soil mix slopes of nearly 80 feet high. We have found that "jumping" successional stages produces cost heavy, materials heavy and maintenance heavy projects with unnecessary survivability risks. Over time, these will provide linkage to scale with adjacent habitat systems. Succesional biomass platforms need to be created. Our principles and strategies are transferable from site to site but techniques and materials need to be site appropriate. Site specificity will play a role in developing alternatives analysis for specific project locations. Safe Harbor Environmental Education Publications are free. We have developed innovative techniques (low impact, low profile, low maintenance and low cost) to re-establish PERFORMANCE OF stability, STORM WATER MANAGEMENT AND HABITAT.Ĭlick on the link below if you want a copy of our publication, revised, 2015. Safe Harbor uses natural systems to stabilize steep, very steep slopes and eroding coastal bluffs.
