Subsidizing Carbon Sequestration Via Forestry In Maryland: A Cost-Benefit Assessment, Rachel C. Hettich

Open Access Theses

Carbon sequestration by forestry is one way to mitigate climate change, and policy incentives are in place to encourage private investment in forestry. State and federal forestry cost-share programs subsidize the establishment of trees and the improvement of existing forested land. The objective of this research was to determine the effectiveness of such programs in Maryland and to compare the monetized benefits from permanently sequestered carbon with the current subsidies. To meet this objective, private and social cost-benefit analyses were conducted for three forestry investment scenarios in Maryland that coincide with the main cost-share programs available there. Sensitivity analysis considered …

Use Of Plastic Bottles As An Alternative Container Type For Propagation Of Forest Tree Seedlings In Restoration Programs, Safiullah Khurram

Open Access Theses

Deforestation and forest degradation is a global issue, especially in poor and developing regions of the world. In order to combat deforestation it is critical to enhance the productivity of forest restoration operations, which often involve planting of nursery-grown forest tree seedlings. Production of low quality stock types with deformed and spiraled root systems is a significant issue hindering successful restoration programs. Polybags (i.e., small plastic bags) are a common container type for seedling propagation in developing countries. However, polybags produce seedlings with spiraled and deformed root systems that reduce outplanting survival and performance. Use of discarded plastic water bottles …

Killing To Save: Trophy Hunting And Conservation In Mongolia, Lucy Page

Independent Study Project (ISP) Collection

Since transitioning to capitalism in 1990, Mongolia’s wildlife has faced growing threats from the development of infrastructure, increasing livestock populations, and the expansion of an illegal trade in wildlife products. As wildlife populations face these growing risks, Mongolia needs to develop and implement strong wildlife management practices, including tighter enforcement of existing wildlife trade laws, more frequent wildlife population studies, and better legislation. However, these revisions will require significant funding. Trophy hunting, the system through which the Mongolian government sells wealthy foreigners expensive permits to hunt species like argali, ibex, wolf, and roe deer, may be a major source for …

Taking Root: An Analysis Of The Best Method For Active Forest Regeneration In The Cloud Forest, Charlotte Startin

Independent Study Project (ISP) Collection

The cloud forest is a biodiversity hotspot and provides many vital ecological and economic services. Unfortunately, deforestation for pastures in the lower montane cloud forest is high. Many pastures become abandoned, leaving highly disturbed open areas of land where natural forest regeneration is poor. Human intervention to encourage ecological restoration is very important to re-establish the proper structure and functioning of the ecosystem. Forest regeneration projects are rare and often unsuccessful, which is why increased knowledge and skills of successful and practical methods for assisted regeneration are needed. The Inti Llacta Reserve in the Pichincha province in Ecuador protects a …

Using The Landsat Data Archive To Assess Long-Term Regional Forest Dynamics Assessment In Eastern Europe, 1985-2012, S. Turubanova, P. Potapov, A. Krylov, A. Tyukavina, Jessica L. Mccarty, V. C. Radeloff, M. C. Hansen

Michigan Tech Research Institute Publications

Abstract. Dramatic political and economic changes in Eastern European countries following the dissolution of the “Eastern Bloc” and the collapse of the Soviet Union greatly affected land-cover and land-use trends. In particular, changes in forest cover dynamics may be attributed to the collapse of the planned economy, agricultural land abandonment, economy liberalization, and market conditions. However, changes in forest cover are hard to quantify given inconsistent forest statistics collected by different countries over the last 30 years. The objective of our research was to consistently quantify forest cover change across Eastern Europe from 1985 until 2012 using the complete Landsat …

Animal Habitat Utilization And The Impacts Of Small-Scale Disturbances On Vegetation Within Larch Forests In Northeastern Siberia, Aaron Phillip White

Theses and Dissertations - UTB/UTPA

Boreal forests support a variety of animals distributed across a matrix of habitat patches including forests of different ages and stand densities. These forests occur at high latitudes where cold and moist conditions favor ground layer dominance by mosses and slow decomposition rates, resulting in a thick soil organic layer (SOL) comprised primarily of decomposing mosses and roots. However, limited information is available on how animal use varies across habitat types in northeastern Siberia. Boreal forests of this region are unique because they are comprised of a single deciduous conifer, Cajander larch (Larix cajanderi). These forests also occur on a …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Understanding the relationship between photosynthesis, net primary productivity and growth in forest ecosystems is key to understanding how these ecosystems will respond to global anthropogenic change, yet the linkages among these components are rarely explored in detail. We provide the first comprehensive description of the productivity, respiration and carbon allocation of contrasting lowland Amazonian forests spanning gradients in seasonal water deficit and soil fertility. Using the largest data set assembled to date, ten sites in three countries all studied with a standardized methodology, we find that (i) gross primary productivity (GPP) has a simple relationship with seasonal water deficit, but …

Building Resilience Into Quaking Aspen Management, Paul C. Rogers

Aspen Bibliography

Throughout the 20^th century, forest scientists and land managers were guided by principles of succession with regard to aspen forests. The historical model depicted aspen as a "pioneer species" that colonizes a site following disturbance and is eventually overtopped by conifers. Aspen systems are more diverse, however, than previously described. Not only are there distinctive seral and stable aspen, but variations within these types require appropriate management considerations (Rogers et al. 2014). We recommend a strategic approach to aspen resilience that builds upon traditional aspen ecology and incorporates knowledge of varying aspen functional types, effective monitoring, historical disturbance ecology, …

Managing Ungulate Browsing For Sustainable Aspen, Samuel B. St. Clair, Paul C. Rogers, Michael R. Kuhns

Aspen Bibliography

In montane forests of the Intermountain West composition and function are often defined by what happens with quaking aspen. Aspen is a pioneer species that regenerates quickly following disturbance and then establishes ecological conditions under which the rest of the biological community develops. Quaking aspen forests have high biodiversity and provide ideal habitat for many animals. Aspen regeneration from root sprouts is highly palatable to wildlife and livestock. When browsing becomes chronic it leads to regeneration failure and eventual loss of aspen forests and associated species. Ironically, this can result in habitat and forage loss for wildlife and livestock. Here …

Morphological And Moisture Availability Controls Of The Leaf Area-To-Sapwood Area Ratio: Analysis Of Measurements On Australian Trees, Henrique Furstenau Togashi, Iain Colin Prentice, Bradley John Evans, David Ian Forrester, Paul Drake, Paul Feikema, Kim Brooksbank, Derek Eamus, Daniel Taylor

Natural Resources Research Articles

1. The leaf area-to-sapwood area ratio (LA:SA) is a key plant trait that links photosynthesis to transpiration. The pipe model theory states that the sapwood cross-sectional area of a stem or branch at any point should scale isometrically with the area of leaves distal to that point. Optimization theory further suggests that LA:SA should decrease toward drier climates. Although acclimation of LA:SA to climate has been reported within species, much less is known about the scaling of this trait with climate among species.
2. We compiled LA:SA measurements from 184 species of Australian evergreen angiosperm trees. The pipe model was …

Modeling Predator Habitat To Enhance Reintroduction Planning, Shiloh Michael Halsey, William J. Zielinski, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

Context

The success of species reintroduction often depends on predation risk and spatial estimates of predator habitat. The fisher (Pekania pennanti) is a species of conservation concern and populations in the western United States have declined substantially in the last century. Reintroduction plans are underway, but the ability of the species to establish a selfsustaining population is affected by predation from its primary predator, the bobcat (Lynx rufus).

Objectives

To develop a habitat model that incorporates both habitat of the focal species and the spatial patterning of predator habitat. To locate areas of densely aggregated habitat that would be suitable …
