Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor 2018 University of Arizona

Climate Sensitivity And Potential Vulnerability Of Guatemalan Fir (Abies Guatemalensis) Forests In Totonicapán, Guatemala, Talia G. Anderson, Daniel Griffin, Kevin Anchukaitis, Diego Pons, Matthew Taylor

Journal of Latin American Geography

Despite continued forest loss and extensive demand for wood products throughout Guatemala, the locally managed and protected forests of Totonicapán remain some of the most intact within the country. Here, we study the growth rings of Guatemalan fir (Pinaceae; Abies guatemalensis Rehder; pinabete) at Totonicapán to assess environmental influences on tree growth and the potential vulnerability of these forests to climate change in the western highlands. We find that late summer and dry season precipitation are critical drivers in annual ring-width variability and that tree growth responds negatively to warm sea surface temperature anomalies in the eastern tropical Pacific. Considering ...


Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane McKenna 2018 Utah State University

Managing For Multiple Objectives In Southwestern Forests: Evaluating The Trade-Offs Between Enhancing Mexican Spotted Owl Nest Habitat And Mitigating Potential Crown Fire, Daniel C. Deane Mckenna

All Graduate Theses and Dissertations

The Forest Inventory and Analysis (FIA), the United States’ forest census, measured sixty-six Mexican spotted owl nest stands in order gain insight into the structure and composition of the nest habitat of this threatened species. I used these data, along with the greater FIA database and the Forest Vegetation Simulator to explore questions surrounding the management of Mexican spotted owl habitat, specifically how to balance the objective of sustaining and enhancing nest habitat in face of increasing forest fire size and severity in the Southwest. My research consisted of three studies. The first study quantified the structure and composition of ...

On-Road Emissions Of Ammonia: An Underappreciated Source Of Atmospheric Nitrogen Deposition, Mark E. Fenn, Andrzej Bytnerowicz, Susan L. Schilling, Dena M. Vallano, Erika S. Zavaleta, Stuart B. Weiss, Connor Morozumi, Linda H. Geiser, Kenneth Hanks 2018 USDA Forest Service

We provide updated spatial distribution and inventory data for on-road NH3 emissions for the continental United States (U.S.) On-road NH3 emissions were determined from on-road CO2 emissions data and empirical NH3:CO2 vehicle emissions ratios. Emissions of NH3 from on-road sources in urbanized regions are typically 0.1– 1.3 t km−2 yr−1 while NH3 emissions in agricultural regions generally range from 0.4–5.5 t km−2 yr−1, with a few hot spots as high as 5.5–11.2 t km−2 yr−1. Counties with ...


Ecological-Economic Assessment Of The Effects Of Freshwater Flow In The Florida Everglades On Recreational Fisheries, Christina Estela Brown, Mahadev G. Bhat, Jennifer S.

This research develops an integrated methodology to determine the economic value to anglers of recreational fishery ecosystem services in Everglades National Park that could result from different water management scenarios. The study first used bio-hydrological models to link managed freshwater inflows to indicators of fishery productivity and ecosystem health, then link those models to anglers' willingness-to-pay for various attributes of the recreational fishing experience and monthly fishing effort. This approach allowed us to estimate the foregone economic benefits of failing to meet monthly freshwater delivery targets. The study found that the managed freshwater delivery to the Park had declined substantially ...


Persistence Of Stream Restoration With Large Wood, Redwood National And State Parks, California, Diedra L. Rodriguez 2018 Humboldt State University

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

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 ...


Productivity And Cost Of A Cut-To-Length Commercial Thinning Operation In A Northern California Redwood Forest, Kigwang Baek 2018 Humboldt State University

Productivity And Cost Of A Cut-To-Length Commercial Thinning Operation In A Northern California Redwood Forest, Kigwang Baek

Theses and projects

Cut-to-length (CTL) harvesting systems have recently been introduced to the redwood forests of California’s north coast. These machines are being used to commercially thin dense redwood (Sequoia sempervirens) stands which tend to form clumps of stems that vigorously sprout from stumps after a harvest. One of the challenges is to avoid damaging residual trees which can decrease productivity, increase costs, and lower the market value of trees. The goal of this study was to evaluate the productivity and costs associated with CTL systems used in a redwood forests and use that data to develop equations for predictions. Time and ...


Impacts On Soils And Residual Trees From Cut-To-Length Thinning Operations In California's Redwood Forests, Kyungrok Hwang 2018 Humboldt State University

Impacts On Soils And Residual Trees From Cut-To-Length Thinning Operations In California's Redwood Forests, Kyungrok Hwang

Theses and projects

In northern California, a cut-to-length (CTL) system was used for the first time to harvest young redwood forests (Sequoia sempervirens (Lamb. ex D. Don) Endl.). However, landowners and public agencies are concerned about the potential negative impacts of CTL logging to soils and residual trees since the extent and amount of CTL impacts are unknown in these forests. This study was designed to (1) determine soil physical property using bulk density (BD) and hydraulic conductivity (HC) (2) examine the characteristics of stand damage after CTL harvesting, and (3) compare the scar size differences between tree growing patterns (individuals vs. clumps ...
