Recognizing and restoring open forests of savannas and woodlands

Science Spotlights Posted on: April 25, 2019
Although not presented in textbooks, open forests were the dominant historical forested ecosystems of the United States. Eastern and western oak forests and southeastern pine forests no longer occur at landscape scales. Management for open oak and pine forests will provide herbaceous habitat, critical to many declining bird and pollinator species.

Open forest management for early successional birds

Publications Posted on: March 27, 2019
Wildlife biologists classify some bird species as early successional because of apparent dependence on early successional vegetation such as forbs, grasses, shrubs, and small trees.

A reconceptualization of open oak and pine ecosystems of eastern North America using a forest structure spectrum

Publications Posted on: November 15, 2018
We present a reconceptualization of forests in eastern North America by differentiating the ecological characteristics of open oak (Quercus) and pine (Pinus) forests from closed successional and oldgrowth forests. Despite historical abundance of savannas and woodlands, the fundamental ecology of open forest ecosystems remains ill-defined when compared to either closed forests or grasslands.

Restoration of temperate savannas and woodlands [Chapter 11]

Publications Posted on: October 04, 2017
Savannas and woodlands are open forest phases that occur along a gradient between grasslands and closed canopy forests. These ecosystems are characterized by open to nearly closed canopies of overstorey trees, relatively sparse midstorey and understorey woody vegetation, and dense, species-rich ground flora. In contrast to closed forests, the dominant and codominant trees in the canopy of open forests often have large, spreading crowns.

Effects of climate change on rangeland vegetation in the northern Rockies [Chapter 6]

Publications Posted on: October 02, 2017
A longer growing season with climate change is expected to increase net primary productivity of many rangeland types, especially those dominated by grasses, although responses will depend on local climate and soil conditions. Elevated atmospheric carbon dioxide may increase water use efficiency and productivity of some species.

Restoring Native California Oaks on Grazed Rangelands

Publications Posted on: May 12, 2016
Efforts to regenerate oaks on California’s oak woodlands often must address how to establish seedlings in areas grazed by livestock. Research indicates that damage to young oak seedlings from cattle varies by season, with less damage during the winter when deciduous oaks do not have leaves.

Dynamics of a pinyon-juniper stand in northern Arizona: a half-century history

Publications Posted on: May 12, 2016
This paper adds to the limited knowledge of stand dynamics in pinyon-juniper woodlands by reporting on the changes in species composition, numbers of trees, arrangements of trees, and total height and volume in a stand from late 1938 to early 1991. This information should be helpful in managing pinyon-juniper woodlands to sustain their productivity and maintain their multiple-use values.

Ecology and management of oak and associated woodlands: Perspectives in the southwestern United States and northern Mexico; 1992 April 27-30; Sierra Vista, AZ

Publications Posted on: January 07, 2016
This symposium focused on technologies that bridge the gap between research and its application in the management of woodlands. Topic areas include: ecology and silvicutural practices; growth, yield, and utilization potentials; livestock and grazing practices; wildlife habitat and values; and hydrology and watershed management.

Farmers' objectives toward their woodlands in the upper Midwest of the United States: implications for woodland volumes and diversity

Publications Posted on: April 04, 2012
This paper reports the results of a study that explores the relationship between farm woodland owners' stated intentions for owning woodland, and the structure and composition of these woodlands in the states of Illinois, Indiana and Iowa in the upper Midwest of the United States.

A landscape approach for ecologically based management of Great Basin shrublands

Publications Posted on: December 03, 2009
Native shrublands dominate the Great Basin of western of North America, and most of these communities are at moderate or high risk of loss from non-native grass invasion and woodland expansion. Landscape-scale management based on differences in ecological resistance and resilience of shrublands can reduce these risks.
