Eco-Buffers: A High Density Agroforestry Design Using Native Species
Schroeder, W. National Proceedings: Forest and Conservation Nursery Associations - 2011, p. 72-75. USDA Forest Service, Rocky Mountain Research Station, Proceedings RMRS-P-68. 2012.
This study showed that Eco-Buffers are characterized by rapid establishment and superior survival when compared to single species buffers. Height of green ash (Fraxinus pennsylvanica Marsh. var. subintegerrima (Vahl.) Fern.) after eight growing seasons averaged 415 cm when growing in an Eco-Buffer compared to 333cm in the single species buffer. Site capture in the Eco-Buffer was 100 percent after eight years whereas the single species buffer had heavy herbaceous weed understory. In eight years plant density increased from 5000 to 35,000 plants/ha plants in the Eco-Buffer compared to a decline from 3500 to 3250 plants/ha with the single species design. This was due in large part to the development of rhizome shoots with pin cherry (Prunus pensylvanica L.), choke cherry (Prunus virginiana var. melanocarpa (A. Nels.) Sarg.) and Wood’s rose (Rosa woodsii Lindl.). The study showed that Eco-buffers establish more quickly and out-compete herbaceous competition resulting in superior growth compared to single species shelterbelts.
