Condition of live fire-scarred ponderosa pine twenty-one years after removing partial cross-sections

Publications Posted on: October 05, 2018
Concern over the effects of removing fire-scarred partial cross-sections may limit sampling of live ponderosa pine to reconstruct fire history. We report mortality rates for ponderosa pine trees 20 to 21 years after removing fire-scarred partial cross-sections to reconstruct fire history.

Assessing high-cost wildfires in relation to the natural distribution of ponderosa pine in the 11 Western states (2000-2017)

Publications Posted on: October 04, 2018
In this analysis we introduce a broad-scale long-term overview of the US West’s costliest wildfires in relation to the natural distribution of ponderosa pine (Pinus ponderosa). The species is dependent on frequent, low-intensity burning, but in absence of this function, it has become one of the region’s most altered ecosystems (U.S. Government Accounting Office, 1999; U.S.D.A.

Effects and interactions of fire, logging, and grazing

Publications Posted on: August 01, 2018
In this chapter, we summarize current knowledge about the effects of fire, logging, and grazing on coniferous forest birds and their habitats. We critically review the results of studies evaluating how these individual factors influence bird numbers, species diversity, nesting success, and habitat use in ponderosa pine forests.

Summary (Songbird ecology in southwestern ponderosa pine forests: A literature review)

Publications Posted on: August 01, 2018
Most ornithological studies in Southwestern ponderosa pine forests have yielded results that are applicable only to the specific location and particular conditions of the study areas (for example, Green 1979 and Hurlbert 1984).

Characterizing spatial neighborhoods of refugia following large fires in northern New Mexico, USA

Publications Posted on: July 10, 2018
The spatial patterns resulting from large fires include refugial habitats that support surviving legacies and promote ecosystem recovery. To better understand the diverse ecological functions of refugia on burn mosaics, we used remotely sensed data to quantify neighborhood patterns of areas relatively unchanged following the 2011 Las Conchas fire.

Biochar effects on the nursery propagation of 4 northern Rocky Mountain native plant species

Publications Posted on: May 10, 2018
Biochar has emerged as a promising potential amendment of soilless nursery media for plant propagation.

Collaborative restoration effects on forest structure in ponderosa pine-dominated forests of Colorado

Publications Posted on: May 10, 2018
In response to large, severe wildfires in historically fire-adapted forests in the western US, policy initiatives, such as the USDA Forest Service’s Collaborative Forest Landscape Restoration Program (CFLRP), seek to increase the pace and scale of ecological restoration. One required component of this program is collaborative adaptive management, in which monitoring data are used to iteratively evaluate and improve future management actions.

Restoring dry and moist forests of the inland northwestern United States [Chapter 23]

Publications Posted on: April 23, 2018
The complex topography of the Inland Northwestern United States (58.4 million ha) interacts with soils and a highly variable climate to provide a mosaic of dry and moist mixed conifer forest settings.

Fire regimes approaching historic norms reduce wildfire-facilitated conversion from forest to non-forest

Publications Posted on: April 23, 2018
Extensive high-severity wildfires have driven major losses of ponderosa pine and mixed-conifer forests in the southwestern United States, in some settings catalyzing enduring conversions to nonforested vegetation types. Management interventions to reduce the probability of stand-replacing wildfire have included mechanical fuel treatments, prescribed fire, and wildfire managed for resource benefit.

Uneven-aged silviculture in cedar-hemlock-grand fir ecosystems of the northern Rocky Mountains

Publications Posted on: March 30, 2018
Uneven-aged silviculture is used infrequently in the Northern Rocky Mountains. Because of wildlife, watershed, or scenic issues it is often preferred for managing many stands. While it has been applied in the ponderosa pine (Pinus ponderosa) forests it has had limited application in the grand fir (Abies grandis)-westem redcedar (Thuja plicate)-westem hemlock (Tsuga heterophylla) forests.
