Litter and dead wood dynamics in ponderosa pine 
forests along a 160-year chronosequence

Publications Posted on: December 18, 2019
Disturbances such as fire play a key role in controlling ecosystem structure. In fire-prone forests, organic detritus comprises a large pool of carbon and can control the frequency and intensity of fire. The ponderosa pine forests of the Colorado Front Range, USA, where fire has been suppressed for a century, provide an ideal system for studying the long-term dynamics of detrital pools.

Spatial and temporal patterns in structure, regeneration, and mortality of an old-growth ponderosa pine forest in the Colorado Front Range

Publications Posted on: December 18, 2019
Effective management and restoration of ponderosa pine forests requires an understanding of the heterogeneity of contemporary and historical stand structures. We assessed spatial and temporal patterns of tree establishment, mortality and size structure over a 30-year period in an old-growth ponderosa pine stand in the mid-montane zone of the Colorado Front Range.

COVER: A user's guide to the CANOPY and SHRUBS extension of the Stand Prognosis Model

Publications Posted on: May 12, 2016
The COVER model predicts vertical and horizontal tree canopy closure, tree foliage biomass, and the probability of occurrence, height, and cover of shrubs in forest stands. This paper documents use of the COVER program, an adjunct to the Stand Prognosis Model. Preparation of input, interpretation of output, program control, model characteristics, and example applications are describe.

Miller Creek Demonstration Forest - a forest born of fire: a field guide

Publications Posted on: May 12, 2016
Miller Creek, on the Flathead National Forest in northwest Montana, is a demonstration forest, showing up to 30 years of forest change after clearcutting and a wide range of fire treatments in 1967 and 1968. Differences in tree regeneration and vegetation development are explained for units that were clearcut and prescribed burned, clearcut and burned by wildfire, clearcut and unburned, and uncut and burned by wildfire.

Silvicultural activities in Pringle Falls Experimental Forest, Central Oregon

Publications Posted on: May 12, 2016
Pringle Falls Experimental Forest has been a center for research in ponderosa pine forests east of the crest of the Cascade Range since 1931. Long-term research facilities, sites, and future research opportunities are currently at risk from stand-replacement wildfire because of changes in stand structure resulting from past fire exclusion.

Stocking and structure for maximum growth in sugar maple selection stands.

Publications Posted on: May 12, 2016
The impacts of stocking, structure, and cutting cycle on basal area, cubic foot volume, board foot volume, and diameter growth are considered. Recommendations are provided for maximum growth in uneven-aged sugar maple stands.

Historical (1860) forest structure in ponderosa pine forests of the northern Front Range, Colorado

Publications Posted on: October 05, 2015
Management of many dry conifer forests in western North America is focused on promoting resilience to future wildfires, climate change, and land use impacts through restoration of historical patterns of forest structure and disturbance processes.

Relationships between riparian vegetation and geomorphic process zones in the Toiyabe mountain range in Nevada

Datasets Posted on: August 27, 2015
We conducted a field observational study to investigate the ecological significance of the "process zone" geomorphic classification scheme for riparian ecosystem distribution, composition, and structure. We measured geomorphic characteristics at multiple scales in order to better understand relationships between geomorphology and riparian vegetation, and to suggest improvements to the classification scheme.
