Ico-Mark Version 1.3, Sean Ma Jeronimo, Derek J. Churchill

ICO App

ICO Mark is a tablet- and phone-based application (app) developed for forest managers and forestry field crews to spatially monitor and map forest structure. ICO Mark relies on the Individuals-Clumps- Openings approach to characterizing dry forest spatial patterning, where forests are composed of varying proportions and sizes of individual trees, clumps of trees, and treeless openings. ICO Mark allows users to track individual trees and clumps for both marking pre-harvest, and for monitoring conditions post-harvest.

The Ico Approach To Quantifying And Restoring Forest Spatial Pattern: Implementation Guide, Derek J. Churchill, Sean Ma Jeronimo, Andrew J. Larson, Paul Fischer, Matt C. Dahlgreen, Jerry F. Franklin

ICO App

This document is intended as a “How To” guide for managers and stakeholders wishing to implement the Individual, Clumps, and Openings (ICO) method for silvicultural prescriptions and/or monitoring. This guide is organized into stand-alone chapters. Managers should read and use chapters as they find useful to their own needs.

Density Management In Young Western Larch Stands: Tree Growth, Stand Yield, And Carbon Storage 54 Years After Thinning, Michael S. Schaedel

Graduate Student Theses, Dissertations, & Professional Papers

Long-term silvicultural experiments can be used to test novel ecological hypotheses and answer contemporary management questions that were not envisioned at study initiation. We used a 54-year old western larch precommercial thinning (PCT) study in northwest Montana to examine two sets of questions: (1) how different PCT regimes affect long-term stand yield and tree growth, and (2) how PCT affects total aboveground carbon (C) storage and distribution among C pools. The study has three target densities (494 trees ha^-1, 890 trees ha^-1, and 1680 trees ha^-1) and three numbers of entries to achieve those …

A Case For Untrammeledness As The Foundational Goal Of Wilderness Management, Robert A. Mcglothlin

Graduate Student Theses, Dissertations, & Professional Papers

This thesis addresses the quandary faced by wilderness managers in a time of heightening anthropogenic change, who are tasked with the conflicting goals of leaving wilderness untrammeled from management control, while simultaneously maintaining natural conditions free from human influence. I explain how this debate between conflicting management goals reflects a deeper rift between two competing philosophical paradigms of wilderness stewardship, which I term the Naturalness- paradigm and the Untrammeledness-paradigm. The Naturalness-paradigm embraces a techno-centric view of wilderness stewardship that exalts the role of managers in shaping wilderness ecosystems, whose persistence it considers to be dependent upon human provisioning. The Untrammeledness-paradigm …

Long-Term Impacts Of Fuel Treatments On Tree Growth And Aboveground Biomass Accumulation In Ponderosa Pine Forests Of The Northern Rocky Mountains, Kate A. Clyatt

Graduate Student Theses, Dissertations, & Professional Papers

In western North America, many low-elevation, dry forest types historically experienced frequent, low-severity fires. However, European settlement and fire suppression policies have contributed to over a century of fire exclusion, substantially altering forest structure and composition. There is considerable interest in restoring fire resilient characteristics to these forests through fuel reduction treatments. One limitation of current research on the impacts of fuel treatments is treatment longevity, as few studies have been able to quantify long-term responses to commonly applied treatments. This research evaluated tree growth and aboveground biomass responses 23 years after treatment in two silvicultural installations with different underburning …

Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Many quaking aspen (Populus tremuloides) populations are in decline across the western United States, a trend likely driven by ongoing climate change and past management that has led to increased competition with conifers. Restoration of aspen is a management goal potentially achievable through active forest management, but treatment effects on regeneration and residual growth have not been comprehensively studied. This project examined if removal of competing conifers altered aspen regeneration density, ungulate browsing, and residual adult aspen diameter growth using a control-impact study design. Sampling occurred at the Burnt Fork (ten treatments, four controls) and Bandy (seven treatments, four controls) …
