Project/Client:  Double E Northwest Management Plan
Location:  Newport, Oregon
Scope:  IRM developed a forest management plan for 3,000 acres of private forest land. The plan analyzed management trajectories to restore Swiss Needle Cast infected stands and to multi-species stands focusing on re-introduction of western red cedar.

Project/Client: Fairchild Forest Stewardship Plan
Location:  Philomath, OR
Scope:  IRM was hired to provide a forest inventory and develop a management plan for a 80 acre tract of second growth Douglas fir. IRM designed the inventory, collected the data, and used the Assisi Forest Inventory program to compile and “grow” the stand data.  A fully integrated stewardship plan was developed to guide the management of the tract for the next 30 years. The plan met the requirement of FSC® certification and allowed the tract to be included in IRM pool of FSC® Certified Lands.

Project/Client:  Family Forest Management, Mrs. Helen Berg
Location:  Corvallis, Oregon
Scope:  IRM prepared an integrated stewardship plan for a 120-acre woodlot in Western Oregon. The project involved biological and timber inventory collection, analysis, the formulation of a working management plan, and overseeing of management activities. Detailed prescriptions for all resources was integrated into a concise management plan with the goals of both promoting mature forest habitat while producing timber revenues through thinning. Management activities completed on the property include variable retention thinning, group selection harvests with retention, riparian cedar underplanting, snag and downed wood creation, and an adaptive plan to slowly convert portions of the property to multi-cohort and species condition. Cost sharing for the reforestation project was secure the State of Oregon’s Forest Resources Trust Program.

Project/Client: Stump Springs Environmental Assessment, Dixie National Forest
Location: Escalante, Utah
Scope:  IRM prepared an EA as a sub-contractor to David Evans and Associates, per Region 4 Professional Services Contract,  for a prescribed burn on a 7000-acre watershed on the Escalante ranger district of the Dixie National Forest. As part of this project IRM conducted stand exams and noxious weed surveys of the project area. Our analysis synthesized historic and current vegetation data, historic range of variability analyses, fuel and fire severity models, threatened and endangered species recovery plans, and other keystone indicator species management mandates into a comprehensive forest restoration plan. Recommendations included specific burn prescriptions designed to restore key ecosystem processes and functions at both stand and landscape levels.


Project: Kings Slough Forest Thinning
Location: Newport, OR
Scope: IRM conducted a second-entry forest thinning for longtime client Double E Northwest, on their King Slough Tract located south of Newport.  Forest type is primarily 35year old plantation mix of Sitka Spruce, Douglas-fir, and Western Hemlock. The tract was last thinned in 2003 by IRM, also using a cut to length harvest system. At that time, stem densities were reduced from an overstocked condition of, 600-800 trees per acre (TPA) to 250 TPA.

IRM designed and conducted a stand level inventory for the King Slough Tract. High relative densities shown by inventory data; highlighted the need to reduce the number of TPA yet again.IRM Forest Managers designed a thinning prescription to reduce stems from 250 TPA to 185 TPA. Reducing the stem density will keeps stand vigor high by maintaining large healthy crowns. Thinning will prioritize and target the removal of Douglas fir. King Slough Doug fir is infected by Swiss Needle Cast and shows highly reduced growth rates, and nearly dead tops. Cut to length machinery is processing and will extract short logs for local markets. After completion, the remaining stand will be composed of primarily hemlock and spruce and have increased stem spatial heterogeneity. Open gap areas in the tract will begin to recruit shade tolerant seedlings continuing the stand conversion to a robust spruce – hemlock cover.

Project:  Airport Tree Removal, City of Newport
Location: Newport, OR
Scope: IRM was asked to design a workplan to remove trees in-line with the Newport Airports runways and serve as the City’s technical advisor. The project area was sensitive in nature as it was punctuated by springs and seasonal streams along with the obstructing trees being previously unharvested and very large. Lidar was used to determine which trees obstructed airport runway signal lights and locate the problematic trees.

Project/Client:  Metolius Preserve Young Stand Thinning, Deschutes Basin Land Trust
near Sisters, Oregon
IRM developed a restoration plan and implemented restoration treatments on 600 acres on the Metolius Preserve.  The Metolius Preserve Young Stand Thinning featured both state of the science silviculture and state of the art equipment. The prescription uses “mosaic” thinning in 50 year old “blackbark” pine stands to restore reference era structure. A harvester/forwarder was used to cut, delimb, and buck trees in the woods, thus minimizing large landings and allowing equipment to travel over a bed of limbs.A forwarding machine fully suspended logs by storing them in a bunk and used existing skid trails. The use of a process called “ghosting” significantly decreased the total area in forwarding trails. The mechanization of logging allowed high levels of utilization of each tree (down to a 1″ top).  Upon completion of thinning, a rubber tracked skid steer (LightfootTM) with Fecon Bullhog masticating head, was used as a single treatment to mulch thinning residues and mow understory shrubs and encroaching undesirable grand fir regeneration. Mowing of bitterbrush and other native shrubs has been shown to invigorate and cause resprouting, which improves browse for deer.
