Characteristics of aspen infected with heartrot: Implications for cavity-nesting birds

Publications Posted on: November 29, 2010
Phellinus tremulae is an important fungal decay agent common to aspen and a critical component to the cavity-nesting bird complex found in western aspen stands. Little information exists on the conditions that facilitate infection and spread of P. tremulae in aspen forests. I used Forest Inventory and Analysis (FIA) data to explore the relationships of several tree and stand characteristics to the presence and frequency of P.

Basal area growth for aspen suckers under simulated browsing on Cedar Mountain, southern Utah, western United States of America

Publications Posted on: August 05, 2010
The objective of the study was to determine the effects of season and intensity of clipping using simulated browsing on suckers' (Populus tremulaides Michx.) basal area growth on Cedar Mountain, Southern Utah, Western United States of America. Three randomly selected stands measuring 70 m x 70 m were clear-felled in mid-July, 2005, and fenced.

The aspen mortality summit; December 18 and 19, 2006; Salt Lake City, UT

Publications Posted on: April 22, 2010
The USDA Forest Service Rocky Mountain Research Station sponsored an aspen summit meeting in Salt Lake City, Utah, on December 18 and19, 2006, to discuss the rapidly increasing mortality of aspen (Populus tremuloides) throughout the western United States. Selected scientists, university faculty, and managers from Federal, State, and non-profit agencies with experience working with aspen were invited.

Assessing aspen using remote sensing

Publications Posted on: December 23, 2009
Large areas of aspen (Populus tremuloides) have disappeared and continue to disappear from western forests due to successional decline and sudden aspen decline (SAD). This loss of aspen ecosystems negatively impacts watersheds, wildlife, plants, and recreation. Much can still be done to restore aspen if timely and appropriate action is taken.

The use of landscape fabric and supplemental irrigation to enhance survival and growth of woody perennials planted on reclaimed surface mine lands

Publications Posted on: December 02, 2009
A study was initiated to determine the effectiveness of landscape fabric and supplemental irrigation in survival and growth of woody perennials planted on reclaimed surface coal mine lands. The study compared growth and survival of nursery grown potted aspen and serviceberry planted with or without landscape fabric, and with or without biweekly supplemental irrigation.

Survivor aspen: Can we predict who will get voted off the island?

Publications Posted on: November 24, 2009
During the past few years, aspen have been dying at rates that appear to exceed normal rates. We believe that this mortality should not be unexpected, given the severe drought of the past 10 years. We examine the literature and FIA data and identify several factors that indicate such mortality should be expected.

Decay of aspen (Populus tremuloides Michx.) wood in moist and dry boreal, temperate, and tropical forest fragments

Publications Posted on: March 19, 2009
In this study, we set up a wood decomposition experiment to i) quantify the percent of mass remaining, decay constant and performance strength of aspen stakes (Populus tremuloides) in dry and moist boreal (Alaska and Minnesota, USA), temperate (Washington and Idaho, USA), and tropical (Puerto Rico) forest types, and ii) determine the effects of fragmentation on wood decomposition rates as related to fragment size, forest age (and/ or st

Lichen community change in response to succession in aspen forests of the southern Rocky Mountains

Publications Posted on: March 05, 2009
In western North America, quaking aspen (Populus tremuloides) is the most common hardwood in montane landscapes. Fire suppression, grazing and wildlife management practices, and climate patterns of the past century are all potential threats to aspen coverage in this region. If aspen-dependent species are losing habitat, this raises concerns about their long-term viability.

Fire history and fire management implications in the Yukon Flats National Wildlife Refuge, interior Alaska

Publications Posted on: December 17, 2008
We conducted this investigation in response to criticisms that the current Alaska Interagency Fire Management Plans are allowing too much of the landscape in interior Alaska to burn annually. To address this issue, we analyzed fire history patterns within the Yukon Flats National Wildlife Refuge, interior Alaska. We dated 40 fires on 27 landscape points within the refuge boundaries using standard dendrochorological methods.

Extent of decay associated with Fomes igniarius sporophores in Colorado aspen

Publications Posted on: July 03, 2008
The most destructive decay of aspen (Populus tremuloides Michx.) is caused by Fomes igniarius var. populinus (Neu.) Camb. This fungus accounted for 59 percent of the decay found in a recent study of aspen in Colorado. It is almost impossible to find stands of any age that are not damaged to some degree by F. igniarius, and trees with advanced stages of decay usually bear numerous sporophores or conks.
