Processes underlying restoration of temperate savanna and woodland ecosystems: Emerging themes and challenges

Publications Posted on: November 09, 2020
Open forests of savanna and woodlands span the spectrum between closed canopy forests and treeless grasslands, and therefore contain structure, composition, and function distinctive from either endpoint. In this special issue, researchers provide examples from different open forest ecosystems to examine the underlying ecological principles and specific management challenges affecting successful restoration of these systems.

Fuel treatment longevity in ponderosa pine-dominated forest 24 years after cutting and prescribed burning

Publications Posted on: July 11, 2020
Fuels reduction treatments to mitigate fire behavior are common in ponderosa pine ecosystems of the western United States. While initial impacts of fuel treatments have been reported, less is known about treatment longevity as live and dead fuels change with time.

Ecology, silviculture, and management of Black Hills ponderosa pine

Publications Posted on: June 22, 2020
This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem.

The effects of thinning and similar stand treatments on fire behavior in Western forests.

Publications Posted on: June 22, 2020
In the West, thinning and partial cuttings are being considered for treating millions of forested acres that are overstocked and prone to wildfire. The objectives of these treatments include tree growth redistribution, tree species regulation, timber harvest, wildlife habitat improvement, and wildfire-hazard reduction. Depending on the forest type and its structure, thinning has both positive and negative impacts on crown fire potential.

Forest structure and fire hazard in dry forests of the Western United States

Publications Posted on: June 22, 2020
Fire, in conjunction with landforms and climate, shapes the structure and function of forests throughout the Western United States, where millions of acres of forest lands contain accumulations of flammable fuel that are much higher than historical conditions owing to various forms of fire exclusion.

Biomass flow in western forests: Simulating the effects of fuel reduction and presettlement restoration treatments

Publications Posted on: December 23, 2019
Fuel treatment silviculture and the resulting long-term flow of biomass were examined using data from selected western stands. An uneven-aged management regime with reserve trees was modeled, using a canopy closure of 40 percent for the dominant trees as a target and a harvest cutting cycle of 20 years. Fuel reduction treatments in currently overstocked stands resulted in an initial peak of removal for the first and second cutting cycles.

Long-term seedfall, establishment, survival, and growth of natural and planted ponderosa pine in the Colorado Front Range

Publications Posted on: December 18, 2019
Seedfall, natural regeneration establishment, and growth of planted seedlings was observed from 1981 to 2001 under shelterwood and seedtree overstories in a replicated study in ponderosa pine in the Manitou Experimental Forest in the Colorado Front Range. Good seed crops were produced only every 4 to 6 years, with almost no viable seed produced in intervening years.

Management of forests and forest carnivores: Relating landscape mosaics to habitat quality of Canada lynx at their range periphery

Publications Posted on: October 02, 2019
Connecting forest management with the conservation of forest-associated animals requires an understanding of habitat quality, as well as identifying long-term silvicultural strategies that align with high quality habitat. It is, therefore, essential to characterize the spatio-temporal dimensions of habitat quality.

As a discipline, silviculture has a long legacy of practitioners who mentored the next generation, passing their knowledge - and vision for the future - onward.

Barriers to natural regeneration in temperate forests across the USA

Publications Posted on: January 28, 2019
For millennia, natural disturbance regimes, including anthropogenic fire and hunting practices, have led to forest regeneration patterns that created a diversity of forest lands across the USA. But dramatic changes in climates, invasive species, and human population, and land use have created novel disturbance regimes that are causing challenges to securing desired natural regeneration.
