ProjectTitle: Vollmer Oaks Project

Background:

Oak woodlands benefit over 200 species of wildlife including deer, elk, turkey, and upland birds by providing shelter, mast, and hosting an abundance of grass, forbs, and shrubs among them. Through development, fire suppression, and conifer encroachment this habitat has seen around a 95% decline throughout Oregon and is recognized as a strategy habitat in the Oregon Conservation Strategy. We propose to enhance 25 acres of Oregon White Oak on private land near

Trail, OR by cutting and piling or spreading trees and shrubs less than 10 inches in diameter.

Tasks and Deliverables:

Project location is near Trail, OR, area size is 25 acres.

General: Hand crews or machinery may be used. Walk-in access from landowner barn, and access through neighboring landowner to the east is secured for walk-in when wet, and equipment when dry. Crews and equipment must not disturb soil more than 1.5 inches deep. A sheet of plastic and/or an absorbent pad must be used under fill caps while filling equipment; a safety spill kit must be present.

Slashing: All live and dead standing vegetation greater than 12 inches in height or length, but not over 10 inches DBH will be completely severed with the stump height not to exceed 6 inches. No cutting of Yew, Dogwood, madrone, or manzanita; white oak and black oak up to 4 inches DBH may be cut to allow hand crews or machinery better access but is not required to be cut for this project.

Piling: All slash less than 10 inches in diameter and greater than 2 feet in length shall be piled. Slash less than 2 feet in length will be left on the ground. Slash left on the ground will not exceed 6 inches in depth. All piles will be constructed by laying limbs, stems, cut boles, and other slash in the pile so as to be parallel with each other. Slash that causes large air spaces in the piles will be cut to eliminate air spaces. Each pile will include an area of small sized slash (small branches less than ¼ to ½ inch in diameter and/or small branches with needles or leaves attached) to provide “kindling” for prompt ignition and to aid in combustion of larger slash. These fuels will be placed in the center of the pile. Pile size will be a maximum of 10 feet in diameter by 10 feet in height, and minimum pile size will be 6 feet in diameter by 6 feet in height at the time of final inspection. All piles will be covered with a 4-mil polyethylene plastic or approved alternate material to cover at least 90% of the surface of each pile. All four corners and the middle of the plastic sheets will be anchored with slash. Covering shall be done at the time of piling. Piles will not be closer than 10 feet to leave vegetation or 20 feet to a unit boundary. Slash will not be piled or placed on logs or stumps, in roadways or drainage ditches, or within channel bottoms or streams. Slash will not be piled or placed in buffer zones.

Mulching: In lieu of piling, all slash less than 10 inches in diameter and greater than 2 feet in length can be turned into mulch and spread on the ground not to exceed 2 inches deep.
