Assessing Transboundary Wildfire Exposure In The Southwestern United States, Alan A. Ager, Palaiologos Palaiologou, Cody Evers, Michelle A. Day, Ana M.G. Barros

Environmental Science and Management Faculty Publications and Presentations

We assessed transboundary wildfire exposure among federal, state, and private lands and 447 communities in the state of Arizona, southwestern United States. The study quantified the relative magnitude of transboundary (incoming, outgoing) versus nontransboundary (i.e., self-burning) wildfire exposure based on land tenure or community of the simulated ignition and the resulting fire perimeter. We developed and described several new metrics to quantify and map transboundary exposure. We found that incoming transboundary fire accounted for 37% of the total area burned on large parcels of federal and state lands, whereas 63% of the area burned was burned by ignitions within the …

Evaluating The Effectiveness Of Restoration Treatments To Enhance Oregon White Oak Systems Within The Klickitat River Watershed, Kara Caselas

Environmental Science and Management Professional Master's Project Reports

Oregon white oak (Quercus garryanna) and associated plant communities provide key habitat to a number of plant and animal species, including Washington state listed threatened populations of Western grey squirrel. Over the past 150 years, human actions such as logging, fire suppression and grazing have altered stand structure and species composition of oak systems, reducing the extent and quality of historic Oregon white oak habitat. Oregon white oak and associated habitats are common in Klickitat County, which has one of the largest remaining acreages of Oregon white oak systems in the state of Washington. While most oak systems …

Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda

Independent Study Project (ISP) Collection

Ecuador is one of the most biodiverse places on the planet, and many of the species in the region are found nowhere else in the world. The cloud forest is particularly diverse because the mountainous terrain isolates populations and changes in elevation create a wide variety of habitats. Cerro Mayordomo is a relatively unexplored mountain in the cloud forest of Tungurahua, Ecuador. It is known to have very high levels of endemism and several new species have been discovered there, but the biodiversity of angiosperms on the mountain has never been quantified. In this study, 5x5 m quadrants were established …

Interacting With The Trail: A Comprehensive Approach To Developing An Environmental Education Program For Agnolakely Private Nature Reserve, Claire Hamilton

Independent Study Project (ISP) Collection

Madagascar is a diverse island, biologically and geographically. This has led to the development of endemic species and high biodiversity within the landscape. Unfortunately, due to poverty, extraction of natural resources, and a growing population, these species have become threatened. Agnolakely, is a private nature reserve, located in eastern Madagascar that is trying to combat these challenges through reforestation projects and land protection. Agnolakely is not only of ecological value, but is also integral in the community structure. As Agnolakely expands it has become essential to implement education and outreach for the reserve. This study was designed to collect biological …

Spatiotemporal Variation Of Nutrient Concentrations In The Upper Shule River Basin, The Qinghai-Tibetan Plateau, China, Hongzheng Pu, Yongjian Ding, Tianding Han, Fengjing Liu

Michigan Tech Publications, Part 1

This study aimed to understand the spatiotemporal variation of nutrient concentrations in stream water, using analyses of total nitrogen (TN), NO₃⁻-N, NH₄⁺-N and total phosphorus (TP) concentrations from April to October in 2016 in the upper Shule River basin in the northeastern margin of the Qinghai-Tibetan Plateau. Dissolved inorganic nitrogen (DIN; NO₃⁻-N + NH₄⁺-N) concentrations in both groundwater and stream water were the predominant form of TN, accounting for about 88%. Median concentrations in stream water were 815 μg L⁻¹ for TN, 459 μg L⁻¹ for …

Assessing The Effects Of Climate Change And Fuel Treatments On Forest Dynamics And Wildfire In Dry Mixed-Conifer Forests Of The Inland West: Linking Landscape And Social Perspectives, Brooke Alyce Cassell

Dissertations and Theses

Over the past century in the western United States, warming has produced larger and more severe wildfires than previously recorded. General circulation models and their ensembles project continued increases in temperature and the proportion of precipitation falling as rain. Warmer and wetter conditions may change forest successional trajectories by modifying rates of vegetation establishment, competition, growth, reproduction, and mortality. Many questions remain regarding how these changes will occur across landscapes and how disturbances, such as wildfire, may interact with changes to climate and vegetation. Forest management is used to proactively modify forest structure and composition to improve fire resilience. Yet, …

Water Level Controls On Sap Flux Of Canopy Species In Black Ash Wetlands, Joseph Shannon, Matthew Van Grinsven, Joshua Davis, Nicholas Bolton, Nam Jin Noh, Thomas Pypker, Randall K Kolka

Michigan Tech Publications, Part 1

Black ash (Fraxinus nigra Marsh.) exhibits canopy dominance in regularly inundated wetlands, suggesting advantageous adaptation. Black ash mortality due to emerald ash borer (Agrilus planipennis Fairmaire) will alter canopy composition and site hydrology. Retention of these forested wetlands requires understanding black ash’s ecohydrologic role. Our study examined the response of sap flux to water level and atmospheric drivers in three codominant species: black ash, red maple (Acer rubrum L.), and yellow birch (Betula alleghaniensis Britt.), in depressional wetlands in western Michigan, USA. The influence of water level on sap flux rates and response to vapor pressure deficit (VPD) was tested …

Methods To Improve Survival And Growth Of Planted Alternative Species Seedlings In Black Ash Ecosystems Threatened By Emerald Ash Borer, Nicholas Bolton, Joseph Shannon, Joshua Davis, Matthew J. Van Grinsven, Nam Jin Noh, Shon Schooler, Randall K Kolka, Thomas Pypker, Joseph Wagenbrenner

Michigan Tech Publications, Part 1

Emerald ash borer (EAB) continues to spread across North America, infesting native ash trees and changing the forested landscape. Black ash wetland forests are severely affected by EAB. As black ash wetland forests provide integral ecosystem services, alternative approaches to maintain forest cover on the landscape are needed. We implemented simulated EAB infestations in depressional black ash wetlands in the Ottawa National Forest in Michigan to mimic the short-term and long-term effects of EAB. These wetlands were planted with 10 alternative tree species in 2013. Based on initial results in the Michigan sites, a riparian corridor in the Superior Municipal …

Education Institutions Creation Of Partnerships, Iwasan D. Kejawa Ed.D

Department of Educational Administration: Faculty Publications

This issue is embracing the creation of partnerships with establishments worldwide for the provisions of life embodiments to graduates. At moment, there may be lack of friendship or partnership with establishments to create incentives for newly graduates of so many colleges and universities (Hirsh & Weber, 1999). Partnership with external companies will surely bring enormous grants to the colleges and universities and it will also encourage friendly establishments to provide incentives and perks to colleges, universities and alumni. It may be concluded that the advantages of creating rapport with external congruences is the comraderies and also compromises that will be …

Predicting Potential Fire Severity Using Vegetation, Topography And Surface Moisture Availability In A Eurasian Boreal Forest Landscape, Lei Fang, Jian Yang, Megan White, Zhihua Liu

Forestry and Natural Resources Faculty Publications

Severity of wildfires is a critical component of the fire regime and plays an important role in determining forest ecosystem response to fire disturbance. Predicting spatial distribution of potential fire severity can be valuable in guiding fire and fuel management planning. Spatial controls on fire severity patterns have attracted growing interest, but few studies have attempted to predict potential fire severity in fire-prone Eurasian boreal forests. Furthermore, the influences of fire weather variation on spatial heterogeneity of fire severity remain poorly understood at fine scales. We assessed the relative importance and influence of pre-fire vegetation, topography, and surface moisture availability …

Changing Rainfall Frequency Rather Than Drought Rapidly Alters Annual Soil Respiration In A Tropical Forest, Qi Deng, Deqiang Zhang, Xi Han, Guowei Chu, Quanfa Zhang, Dafeng Hui

Biology Faculty Research

Tropical forests play an important role in global carbon (C) cycling due to high primary productivity and rapid litter and soil organic C decomposition. However, it is still unclear how changing rainfall will influence soil CO2 losses (i.e. via soil respiration) in tropical forests. Here, using a rainfall and litter manipulation experiment in a tropical forest, we show that enhanced litter-leached dissolved organic carbon (DOC) production with increased rainfall frequency drives substantial CO2 loss via soil respiration. A 50% increase in rainfall frequency (no change in total rainfall amount) enhanced inputs of DOC by 28%, total dissolved nitrogen (TDN) by …
