IRM uses the following technologies to maximize effectiveness of forest management planning and actions:
Stand Visualization System (SVS) is a computer based imaging program which provides a graphic display (shown below) at the stand level of forested stands including trees, snags, and understory vegetation. Coupled with an inventory and growth modeling program such as FPS, SVS allows the viewer to “see” the development of a stand from planting through various silvicultural treatments to full maturity.
Geographic Information Systems mapping (GIS) is an automated computer mapping program for the capture, storage, retrieval, analysis, and display of spatial data. IRM uses the latest version of ArcView; the industry standards for highly accurate and functional spatial analysis and map making.
Global Positioning Systems (GPS) uses satellite signals to provide highly accurate locations in the field. This technology is used to collect mapping data for incorporation into a GIS system.
Growth and Yield Models IRM uses ORGANON, DFSIM, and the FVS computer-based growth and yield models.
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, Past Mayor
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: Integrated Stewardship Plan, Carter Kerns
Location: Pendleton, OR
Scope: IRM prepared an integrated stewardship plan/riparian restoration plan for a 600 acre forested parcel along one of the major tributaries of the North Fork of the John Day River in Eastern Oregon. The project involved data collecting, analysis, and the writing of a management plan. The project involved the data collection and analysis on vegetation, fisheries, soils, roads, recreation and wildlife. Detailed prescriptions for all resources was integrated into a concise management plan which addressed the objectives of the landowner and provided direction for the sound management of his resources for the next thirty years. Some of the mitigation measures used were: fencing of riparian areas, salvage thinning for forest health, snag creation, and in stream fish habitat structures. A detailed interpretive and recreation plan was created for the landowner. Federal Funding through the Bonneville Power Administration was secured for the restoration of the riparian area.
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.
