Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez

Cal Poly Humboldt theses and projects

The conservation and recovery of anadromous salmonids (Oncorhynchus sp.) depend on stream restoration and protection of freshwater habitats. In-stream large wood dictates channel morphology, increases retention of terrestrial inputs such as organic matter, nutrients and sediment, and enhances the quality of fish habitat. Historic land use/land cover changes have resulted in aquatic systems devoid of large wood. Restoration by placement of large wood jams is intended to restore physical and biological processes. An important question for scientists and restoration managers, in addition to the initial effectiveness of restoration, is the persistence and fate of large wood installations. In this …

Great Basin Forb Restoration: Lupine Response To Altered Precipitation Predicted By Climate Change, Andrea Jo Johnson, Kristin Hulvey, Scott Jensen, Tom Monaco

Research on Capitol Hill

Abundance of native forb species is declining, leading to degraded ecosystems within the Great Basin.

Forbs provide many ecosystem functions, including wildlife habitat for species such as Sage Grouse, increased biodiversity, resistance to erosion, and protection from invasive plant species.

Climate change is predicted to affect timing, frequency, and intensity of precipitation within the Great Basin. During the fall season, precipitation is expected to increase by 30%.

Changes in precipitation will likely affect fall emergence of forbs, which is essential for overwintering and establishment.

Learning how precipitation affects forb emergence could lead to new methods that increase fall emergence and …

Herbivory Impacts On Growth And Survival Of Seedlings In Bottomland Hardwood Forest Restoration Sites In The Post Oak Savannah And Blackland Prairie Ecoregions Of Texas, Usa, Ryan J. Jacques

Electronic Theses and Dissertations

Interest in bottomland hardwood forests (BLHW) ecology and restoration has increased over the past 40 years. These communities aid in water quality improvement, streambank stabilization, and urban expansion mitigation. They also provide important habitat for many species of wildlife. Since the majority of remaining BLHW are degraded due to land fragmentation, restoration attempts are becoming commonplace within the Western Gulf Coastal Plain. However, restoration success has been mixed, with managers observing survival rates of <15% for desirable species due to various factors. Over two growing seasons, I investigated multiple factors that have potential to limit BLHW restoration success in East Texas. Specifically, I tested the impacts of herbivory by white-tailed deer (Odocoileus virginianus) and feral swine (Sus scrofa) on Nuttall oak (Quercus texana Buckley), Shumard oak (Q. shumardii Buckley), bur oak ( …

Afforestation Of Arid And Semiarid Ecosystems In Turkey, Servet Çalişkan, Meli̇h Boydak

Turkish Journal of Agriculture and Forestry

Sustainable management of arid and semiarid forests requires careful planning and implementation. Afforestation by planting and seeding is a fundamental tool for the establishment of new forests on barren landscapes and restoration of degraded forests in arid and semiarid ecosystems. In afforestation efforts, the consideration of site preparation, selection of species, seed source, and planting methods pose a number of ecological and economic challenges. Possessing one of the world's richest floras, Turkey suffered from heavy degradation during the last millennia. Some studies suggested that forests and steppes once covered 60%-70% and 10%-15% of the Anatolian landscape, respectively. Growing population, overgrazing, …

Growth Response Of Whitebark Pine (Pinus Albicaulis) Regeneration To Thinning And Prescribed Burn Release Treatments, Molly L. Mcclintock Retzlaff

Graduate Student Theses, Dissertations, & Professional Papers

Whitebark pine (Pinus albicaulis Engelm.) plays a prominent role throughout high-elevation ecosystems in the northern Rocky Mountains. It is an important food source for many birds and mammals, as well as a major player in high-elevation watershed maintenance, both slowing snowmelt and stabilizing soils. Whitebark pine is vanishing from the landscape due to three main factors – white pine blister rust (Cronartium ribicola) invasions, mountain pine beetle (Dendroctonus ponderosae) outbreaks, and successional replacement by more shade-tolerant tree species historically controlled by wildfire. In the past century, human activity such as fire suppression has altered these …

Long-Term Overstory Vegetation Responses To Prescribed Fire Management For Longleaf Pine At Big Thicket National Preserve, Deanna M. Boensch

Electronic Theses and Dissertations

At the western edge of the longleaf pine (Pinus palustris) range, federal land managers have burned the forests of Big Thicket National Preserve to bring back the structure and diversity of the longleaf pine forest. In the early 1990’s, a four year study was conducted by Rice University, and the National Park Service continued monitoring the study’s fire ecology research plots. After two decades of data collection, ordination was applied to species abundance data to examine changes in vegetation communities from a variety of prescribed fire treatments and controls. The vegetation data was separated by size class to include overstory, …

Aspen Bibliography

The Forest Service proposes to reduce the risk of wildfire, to protect, restore, and enhance forest ecosystem components (i.e., streams, meadows, aspen areas) in the vicinity of Gibsonville, California. A combination of hazard tree removal, forest health, and fuels reduction treatments are proposed on 1,200 acres of Forest Service system lands. These actions are proposed to be implemented on the Feather River Ranger District of the Plumas National Forest.

Long-Term Impacts Of Fuel Treatments On Tree Growth And Aboveground Biomass Accumulation In Ponderosa Pine Forests Of The Northern Rocky Mountains, Kate A. Clyatt

Graduate Student Theses, Dissertations, & Professional Papers

In western North America, many low-elevation, dry forest types historically experienced frequent, low-severity fires. However, European settlement and fire suppression policies have contributed to over a century of fire exclusion, substantially altering forest structure and composition. There is considerable interest in restoring fire resilient characteristics to these forests through fuel reduction treatments. One limitation of current research on the impacts of fuel treatments is treatment longevity, as few studies have been able to quantify long-term responses to commonly applied treatments. This research evaluated tree growth and aboveground biomass responses 23 years after treatment in two silvicultural installations with different underburning …

Quantifying Effects Of Quaking Aspen Silvicultural Treatments On Aspen Regeneration And Residual Growth, Philip W. Williams

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Many quaking aspen (Populus tremuloides) populations are in decline across the western United States, a trend likely driven by ongoing climate change and past management that has led to increased competition with conifers. Restoration of aspen is a management goal potentially achievable through active forest management, but treatment effects on regeneration and residual growth have not been comprehensively studied. This project examined if removal of competing conifers altered aspen regeneration density, ungulate browsing, and residual adult aspen diameter growth using a control-impact study design. Sampling occurred at the Burnt Fork (ten treatments, four controls) and Bandy (seven treatments, four controls) …

Experimental Greenhouse And Field Trials On American Ginseng, Panax Quinquefolium: Implications For Restoration In Appalachia, Emily Thyroff

Senior Honors Projects, 2010-2019

Panax quinquefolium, American ginseng, is one of the more valuable non-timber forest products, NTFPs, providing economic, cultural, and ecological ecosystem services in forests. Although ginseng has a broad distribution range, it is not abundant anywhere due to overharvesting and deer browse. This study included experimental field and greenhouse trials to determine optimal growing conditions given inconsistencies regarding aspect and soil. Three soil series and two aspects (represented by soil moisture in the greenhouse) were manipulated in a factorial design. We hypothesized that there would be significant differences in ginseng performance (germination, survival, leaf area, and height) due to soil and …

Efficacy Of Dormant Season Herbicide Application On Control Of Japanese Honeysuckle (Lonicera Japonica) For Habitat Restoration In Kentucky, Jason L. Weese

Theses and Dissertations--Forestry and Natural Resources

Kentucky’s disappearing native grassland communities provide habitat for native flora and fauna. A study was conducted to compare the efficacy of herbicides in control of the invasive Japanese honeysuckle (Lonicera japonica) applied at times when most native species are dormant. Six herbicide mixtures (glyphosate, glyphosate + imazapyr, glyphosate + imazapic, imazapyr, triclopyr + difluphenzopyr, and metsulfuron + difluphenzopyr) were applied in three seasons to assess the effect of application timing of each mixture on honeysuckle control. Herbicides were applied with a CO² pressurized sprayer at three sites in a randomized complete block design. Pretreatment sampling indicated that …

Effects Of Canopy And Cultural Treatments On Fine Fuel Production, Fire Behavior, And Short-Term Fire Effects In Loblolly Pine (>I/I< L.) Stands Being Restored To Longleaf Pine (>I/I< Mill.), Carsyn Tennant

All Theses

Across the southeastern United States, anthropogenic factors such as land conversion and fire suppression have resulted in the prevalence of loblolly pine in areas historically occupied by longleaf pine. Compared to longleaf pine forests, loblolly stands often contain a substantial broad-leaved midstory and lack the ground layer that contributes fuels essential for the frequent, low intensity surface fire regime necessary to sustain the longleaf ecosystem. Currently, there is considerable interest in restoring longleaf pine habitats to areas occupied by loblolly pine. The retention of mature canopy trees is often necessary to maintain ecosystem function, to preserve habitat features, and to …

Restoring Longleaf Pine (Pinus Palustris) In Loblolly Pine (P. Taeda) Stands On The Coastal Plain Of North Carolina, Huifeng Hu

All Dissertations

To support the development of silvicultural protocols for restoring longleaf pine (LLP; Pinus palustris Mill.) and its characteristic herbaceous understory in loblolly pine (LBP; P. taeda L.) stands, a three-year study was conducted on moderately well- and well-drained soils in Onslow County, North Carolina. A replicated field experiment was conducted to test the effects of selected silvicultural treatments on planted LLP seedlings, understory vegetation, and plant resources. Seven canopy treatments included four uniform canopy density treatments defined by target residual basal area [Control, MedBA (9 m2/ha), LowBA (4.5 m2/ha), and Clearcut] and three circular gap treatments defined by area [LG …

Seeing The Forest For The Trees: Managing Social Conflict And Forest Restoration, Steven E. Daniels, Jens Emborg, Greg B. Walker

Sociology, Social Work and Anthropology Faculty Publications

This paper examines the role that social conflict is likely to play in forest restoration projects. A definition of conflict as “perceived goal interference among interdependent parties” serves as a point of departure for the discussion, and the nature of forest restoration conflict is systematically examined by focusing on each aspect of the definition: perceptions, goal interference, the parties, and their interdependence. Agencies undertaking restoration projects are encouraged to adopt a discourse orientation, wherein they recognize that 1) their public involvement efforts are creating a discourse that can incorporate a wide array of values and voices and 2) groups may …

Assessing Aspen Using Remote Sensing, Randy Hamilton, Kevin Megown, Jeff Dibenedetto, Dale Bartos, Anne Mikeck

Aspen Bibliography

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. However, land managers often lack fundamental information on the location, quantity, and status of aspen stands. This information is needed to plan, implement, and defend aspen restoration activities, but it is often difficult and costly to obtain. Advances in remote sensing technologies can provide cost-effective ways to obtain spatial …

Recreation Visitor Attitudes Towards Management-Ignited Prescribed Fires In The Bob Marshall Wilderness Complex, Montana, Katie Knotek, Alan E. Watson, William T. Borrie, Joshua G. Whitmore, David Turner

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Research at the Bob Marshall Wilderness Complex in Montana explored differences in recreation visitors’ attitudes towards the use of management-ignited prescribed fires in the wilderness. A mail-back survey of visitors (n = 291) during the 2004 season revealed that over half of visitors would accept prescribed fires in wilderness. This support did not vary by ignition purpose: (a) to restore the natural role of fire or (b) to reduce hazardous fuels and potential for fire escaping to non-wilderness lands. Local visitors, however, were significantly more accepting of prescribed fires than non-local visitors across both ignition purposes. A smaller proportion …

Over 345,000 ha of forested swamps occur throughout the Mississippi River Deltaic Plain. Natural and anthropogenic changes in hydrology and geomorphology at local and landscape levels have reduced the productivity in many of these coastal wetland forests areas and have caused the complete loss of forest cover in some places. A summary and interpretation of the available
science, suggestions for policy change, and a multidisciplinary (multi-responsibility) approach were needed to address these issues [in the context of private land]. In response, the Louisiana Governor's office formed a Coastal Wetland Forest Conservation and Use Science Working Group (SWG) and an associated …
