Specifications include, but are not limited to: This is a mastication contract. ALL standing live juniper trees and saplings will be shredded with a wheeled or tracked MECHANICAL MULCHING/SHREDDER (Bullhog) unless they meet the description of a leave tree. Leave trees are defined as bearing trees, old-growth, wildlife trees and pinyon pine trees. Old-growth trees are defined as large, single stemmed junipers (generally greater than 16” in diameter at ground level) having old-growth characteristics. Wildlife trees are trees with nests showing signs of recent activity or trees with a large nest (the nest is greater than 36” in diameter). All pinyon pine trees will be avoided. The contractor will be responsible for identifying and leaving bearing trees, wildlife trees, and large trees with old-growth characteristics once they have been oriented on-site by the Contracting Officer’s Representative (COR). The COR will meet with the contractor on-site and provide a more detailed written and oral description of wildlife trees, trees with oldgrowth characteristics and bearing trees. Juniper cover, densities, and size are variable across the landscape. However, most trees within the project area are medium-sized (10-12’ tall).
