Green Connectivity In Metropolitan Jabodetabek: Climate Change And The Challenge Of Urban Forest, Safira Maharani Putri, Hendricus Andy Simarmata

CSID Journal of Infrastructure Development

Urban areas in Indonesia, particularly the Greater Jakarta metropolitan region (Jabodetabek), are increasingly experiencing the adverse effects of climate change, such as the Urban Heat Island (UHI) phenomenon. Rapid urbanization has contributed significantly to rising greenhouse gas emissions and deteriorating environmental quality. Urban forests are one of the key solutions to mitigate these impacts; however, their spatial distribution in Jabodetabek remains suboptimal and poorly connected. This study uses NDVI as a proxy for urban forest density, where “urban forest” refers to vegetated areas within cities as defined by Presidential Regulation No. 60/2020. The research addresses the following question: How has …

Performance Enhancement For Rufa: Rapid Urban Forest Assessment, Nicholas Tan

Master's Theses

Urban forests are crucial to the livability and resilience of cities, offering critical ecosystem benefits such as air quality enhancement, temperature regulation, and biodiversity. Managing said urban forests is essential to ensure their sustainability and adaptability to rapidly changing environmental and climate conditions. The Rapid Urban Forest Assessment (RUFA) tool was developed to address the need for a standardized approach to evaluating and comparing urban and community forestry programs. By analyzing and aggregating tree-specific data across California, such as canopy cover, tree counts, and diversity scores, RUFA assigns a comprehensive urban forestry score for each city. This score allows for …

Examining Private Landowner And Stakeholder Attitudes, Perceptions, And Knowledge Of Prescribed Fire In Louisiana, Chloe E. Crawford

LSU Master's Theses

Periodic fire was a primary driver of ecosystems across the Southeastern United States for millennia; however, fire suppression policies have become pervasive in the United States and led to increased fuel loads in forests as well as reduced biodiversity and reduced disease resilience. Prescribed fire presents a risk mitigation strategy and land management tool whereby practitioners can apply fire to the landscape in a controlled manner, thus reaping the benefits of fire while minimizing the risks associated with fire. Land in Louisiana is primarily privately managed and owned, so state-level conservation goals cannot be met without private landowner participation. As …

Analyzing Surface Spectral Signature Shifts In Fire-Affected Areas Of Elko County Nevada, Ibtihaj Ahmad, Haroon Stephen

Civil and Environmental Engineering and Construction Faculty Research

This study investigates post-fire vegetation transitions and spectral responses in the Snowstorm Fire (2017) and South Sugarloaf Fire (2018) in Nevada using Landsat 8 Operational Land Imager (OLI) surface reflectance imagery and unsupervised ISODATA classification. By comparing pre-fire and post-fire conditions, we have assessed changes in vegetation composition, spectral signatures, and the emergence of novel land cover types. The results revealed widespread conversion of shrubland and conifer-dominated systems to herbaceous cover with significant reductions in near-infrared reflectance and elevated shortwave infrared responses, indicative of vegetation loss and surface alteration. In the South Sugarloaf Fire, three new spectral classes emerged post-fire, …

A Multidecadal Analysis Of Groundwater Level And Streamflow Decline In Southern Forest Catchments, Western Australia, Richard J. George, Rose-Anne Bell, W. Lachlan Mccaw, Gregory Paul Raper

Natural Resources Research Articles

Previous analysis of hydrological data in the eucalypt dominated forests of Western Australia’s Darling Ranges show that reduced winter rainfall over the last 50 years has lowered groundwater levels and diminished streamflow by up to 70%. Consequently, climate-independent reverse osmosis seawater desalination and groundwater resources now supply Perth and nearby regional areas, as runoff from forested catchments is no longer sufficient or reliable. In the high rainfall (~1200 mm/yr) mixed forest areas dominated by Eucalyptus diversicolor (karri) and Eucalyptus marginata (jarrah) 200 km to the south of Perth (the ‘Southern Forest’), similar analysis of climate impacts on watertables has not …

Early Detection Of Oak Wilt Using Unmanned Aerial Vehicles (Uav) & Computer Vision, Muttaki I. Bismoy

Masters Theses

Forests are critical ecosystems, delivering services such as biodiversity conservation, climate regulation, timber production, and recreation. However, they face increasing threats from pathogens like Bretziella fagacearum, which causes Oak Wilt, a lethal disease that disrupts water transport in oak trees, leading to canopy dieback and eventual death. Traditional detection methods rely on manual ground surveys, which are labor-intensive, time-consuming, and prone to error, particularly in early disease stages.

This research presents an automated, scalable, high-precision Oak Wilt detection system using Unmanned Aerial Vehicles (UAVs) combined with deep learning-based computer vision. Expanding on earlier work with a lightweight CNN achieving an …

Periodic Evaluations Indicate Increased Effectiveness Of Oregon Master Woodland Manager Volunteer Program, Alicia Christiansen, Lauren Grand, Norma Kline, Tiffany Hopkins

Journal of Extension

The Oregon State University Extension Service Master Woodland Manager (MWM) volunteer program trains landowners in core forestry and natural resource topics. Landowners participate in the MWM program to increase their forest management knowledge, improve their own management practices, and prepare them to volunteer in their community (Bowers, 2000). We surveyed MWM volunteers to understand the effectiveness of the program and what barriers exist to volunteering. Volunteers find the program to be increasingly adequate for personal management and answering questions, but time continues to be the biggest barrier for completing required volunteer hours.

Biological, Geological, and Environmental Faculty Publications

Botanical gardens and arboreta have enormous (if often under-realized) potential to increase understanding of restoration as a predictive science while simultaneously serving as platforms promoting large-scale restoration by public and private stakeholders. Public gardens often have deep histories of both research and outreach and, increasingly, engagement in restoration efforts. As a team of researchers and practitioners, we share our experiences using a forest management manipulation at the Holden Arboretum for both research and outreach. Forest management is a key tool for enhancing biodiversity and ecosystem services in young forests. Known as the Working Woods Learning Forest, this restoration simultaneously serves …

Breeding Season Bird Use Of And Non-Native Plants Found In Food Plots In The Southern Appalachian Mountains, Nathan A. Klaus, Kirk Stodola

Georgia Journal of Science

Traditional agricultural style food plots, or wildlife openings, are widely used for wildlife management and hunting opportunities on public and private lands in the Southeastern United States. These habitats are often cited as beneficial for game and nongame wildlife, but there are few published studies examining nongame bird use of food plots in recent decades. Modern concerns about the ecological costs of food plots, particularly fragmentation and invasive non-native species, warrant a new examination of this practice. We conducted avian surveys during the breeding season of 2008 at 39 sites composed of three different treatments: traditional food plots, novel food …

Ecological And Social Resilience In Wildfire-Prone Communities, Melissa Burnett

All Theses

Climate projections suggest extreme weather variability, introducing extremely wet years, followed by years with extreme drought. These weather conditions are creating fire weather conducive to increasing wildfires across the southeast over the next century, which can have extreme ecological consequences. The Appalachian Mountains historically had some of the highest fire frequencies in North America but have been subjected to decades of fire suppression and prevention policies, resulting in an environment subject to more high-severity wildfires. The fall of 2016 was one of the driest seasons on record in this region and resulted in intense and destructive fires in the southeastern …

The Effect Of An Invasive Species (Lantana Camara) And A Fast-Growing Herb (Acanthus Pubescens) On The Plant And Animal Communities In Kibale National Park, Uganda, Kathleen Bufka

Theses and Dissertations

Fast-growing plant species, like Lantana camara and Acanthus pubescens, could threaten biodiversity in Kibale National Park, Uganda. I surveyed plants and wildlife in areas where these plants were frequently encountered compared to those areas where they are infrequent. I found mixed results based on plant traits and the animals considered. My findings support management efforts on these two species to prevent forest degradation.

Stand Strucuture Of Planted Stands In Storm-Water Retention Basins, Jason Lanza

Electronic Theses and Dissertations

Trees assist in stormwater retention basin functionality as efficient sources of water removal, and determining stand structure and leaf area of forests can be a measure of their effectiveness. The structure of forest stands on these basins managed for runoff mitigation has received little attention. We investigated the structure and species composition/diversity (tree and herbaceous) of planted, managed stands and naturally regenerated stands on stormwater retention basins managed by Harris County Flood Control District in Harris County, Texas. We determined stand structure variables (trees per hectare, basal area per hectare, quadratic mean diameter, relative density, average tree height, and percent …

Restoring A Longleaf Pine Savanna In The Wiregrass Gap: Community Responses To Post-Harvest Slash Manipulation, Eva Purcell

All Theses

Now reduced to just a fraction of their historical range, Longleaf pine savannas in the southeastern United States are home to a wide array of species, some of which are threatened or endemic. These characteristics have inspired widespread restoration initiatives in recent decades, accompanied by an expanding literature on how management techniques affect restoration outcomes. However, research is lacking in a unique region of longleaf pine’s range, where the dominant fire-carrying grasses are different: the Wiregrass Gap. This study investigated the effects of three different slash manipulation treatments on restoration outcomes of a Wiregrass Gap longleaf pine savanna. Specifically, we …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

There is growing recognition that tropical forest restoration is key for sequestering carbon and enhancing ecosystem resilience. Soils, roots, and soil biota are central to ecosystem function and services, but belowground recovery is largely overlooked in restoration monitoring frameworks. Here, we outline current understanding of the links between above- and belowground recovery in tropical forests by examining how belowground properties before and after intervention influence recovery; by evaluating whether aboveground recovery can serve as a proxy for belowground dynamics; and by proposing a blueprint for monitoring dynamic soil physical (bulk density, aggregate stability), chemical (organic matter or carbon, pH), and …

Indigenous Science And The Legacy Of Fire: Resilience, Fuels, Mosaics, And Eco-Cultural Landscapes In Oregon’S Coastal And Cascade Range, Julia Alcalá

University Honors Theses

Most of Oregon's western Cascade and Coastal range is a landscape that has historically been considered devoid of mid to low-intensity fires by Western science. However, for time immemorial, Indigenous peoples have been stewarding the forests through the use of "good fire," creating diverse and heterogenous landscapes with mixed fire regimes, ranging from less than a decade to several centuries since the last fire, resulting in a mosaic of patchy forest, oak savannas, prairies, and wetlands. Yet centuries of Indigenous displacement, cultural assimilation, and suppression of cultural burning contributed to this prevailing belief. Despite that, in recent decades, Western scientists …

Pollinator Plant Communities Within Restored Montane Longleaf Pine Ecosystems, Hanen Van Rossem

Master's Theses

Historically the fire-dependent and biodiverse longleaf pine (Pinus palustris) ecosystem was the dominant ecosystem of the Southeastern US. This ecosystem’s range was massively reduced due to land conversion and fire exclusion, causing the decline of many native species. Efforts to restore and protect longleaf pine stands are now ongoing with the goal of expanding habitat and refuge for threatened species. Differences in restoration practices and prior land use may influence the extent to which restored habitat patches can support pollinators and their plants. This study compared pollinator plant biodiversity between restored neighboring montane longleaf pine stands that differed in …

Journal of Human Sciences and Extension

The number of female forest landowners (FFLs) has been growing throughout the United States. This growth demands educational outreach for a demographic that is often behind their male counterparts in experience and education. The purpose of this exploratory study was to design and host educational workshops geared towards FFLs and to answer the following questions using quantitative and qualitative methods: (1) Are the workshops changing FFLs’ confidence in land management? (2) What are FFLs’ intentions after attending workshops? (3) Does confidence or participants’ intentions with their land vary with demographics? (4) Are workshops providing a platform to start FFL social …

The Forest Through The Trees: Modeling The Ecological Niche And Potential Assemblage Distribution Of Oak-Hickory Forests Across The Eastern U.S., Elijah Worley

Electronic Theses and Dissertations

Understanding how tree species’ ranges and populations may shift by the end of the 21^st Century is critical for effective conservation and forest management. Ecological niche models are widely used to predict species distributions by modeling the relationships between environmental variables and species presence. While numerous models have been developed for individual tree species across the USA, there is limited research on how tree species assemblages, such as oak-hickory forests, will respond to changes in climate over time. Maxent modeling software was used to predict potential shifts in suitable habitat for the oak-hickory forest type, based on environmental variables …

Considerations And Techniques For Producing Urban Tree Canopy Maps Using Freely Available And Accessible Methods, Hugh Reed Ellerman

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Urban forests are valued as green infrastructure for the variety of benefits they provide across ecological, social, public health, and economic domains. To understand the distribution of trees, maps are required. Many methods of mapping tree cover use expensive and data-intensive datasets such as hyperspectral and LiDAR imagery, making these methods inaccessible to municipal forest managers. Variations in the modelling approaches of existing, freely available methods are not addressed in sufficient enough detail to understand the trade-offs implicit in these variations. Further, characteristics of urban tree canopy mapping (high spatial resolution imagery, heterogeneous urban environments, the importance of the tree …

Edge Feathering Across Forest-Meadow Ecotones Increases Light Heterogeneity And Understory Plant Diversity, Aruni Kadawatha, Jean H. Burns

Faculty Scholarship

Ecotones, the transitional zones between distinct habitats, are vital for ecosystem functioning and habitat diversity. Traditional management practices frequently create abrupt boundaries, leading to stressful conditions for organisms. To address this challenge, an underutilized land management technique called “edge feathering”, which involves gradual thinning of the canopy along the forest edge, has been introduced. This study, con- ducted at Holden Arboretum in Kirtland, Ohio, investigated the effects of edge feathering on light availability and understory plant diversity in edge feathered and control treatments. We calculated the coefficient of variation in light availability as light heterogeneity and plant diversity indices at …

Understanding The Accuracy And Best Use Of The Woodland Stick As A Tree Height And Diameter Measurement Tool: A Case Study In Oregon, Francisca Belart, Lauren Grand, Alicia Christiansen

Journal of Extension

We conducted a study to assess the accuracy of the Woodland Stick in determining tree diameter and height as compared to professional measurements and how bias can affect tree volume calculation. After comparing professional measurements with five non-professionals (NP’s) using the Woodland Stick, we found that three out of five NP’s had significant differences in mean dbh, and all of the NP’s had significant differences in mean total height. The overall bias for dbh across users was +0.5 inches and +5.1 ft for height. These deviations can result in volume differences between 0 and 30 bf on a single tree.
