A UAS-based approach toward habitat suitability modeling of a rare endemic plant
Predicting habitat and mapping species distributions are important to address declining biodiversity and species extinctions. Habitat suitability models (HSM) predict potential habitat based on a species’ ecological niche, ... -
Classifying FIA Forest Type from a Fusion of Hyperspectral and LiDAR Data
In this study we develop a methodology for classifying FIA defined forest type across the Tanana Inventory Unit (TIU) using a fusion of hyperspectral and LiDAR data. The hyperspectral and LiDAR data used in this study were ... -
Consistency of Aerial LiDAR-Derived Forest Metrics Across Multiple Acquisitions
As remote sensing technology advances, there is growing interest in using LiDAR to compare structural attributes between forest ecosystems and to monitor forests following active management. However, these emerging ... -
Delineating forested river habitats and riparian floodplain hydrology with LiDAR
University of Washington Abstract Delineating forested river habitats and riparian floodplain hydrology with LiDAR. Chris Vondrasek Chair of Supervisory Committee Associate Professor L. Monika Moskal College of the Environment ... -
Estimating aboveground biomass in interior Alaska: statistical methods for coupling remotely sensed data with field observations to improve precision
The United State Forest Service’s (USFS) Forest Inventory and Analysis (FIA) program is charged by Congress to monitor the nation’s forestlands—survey growth, mortality and composition, among other aspects related to the ... -
Fine Scale Remote Sensing of Forest Structure and Condition
Forest structure refers to the three-dimensional arrangement of biophysical elements (i.e., vegetation) within a forested landscape, whereas forest condition is the characteristics of biophysical elements that are not ... -
Freshwater ecosystem monitoring using satellite remote sensing and field surveys
Freshwater ecosystems transfer and transform energy, nutrients and carbon. The color of lakes and rivers, as observed from space, can provide clues to their ecological function and response to anthropogenic activities. ... -
Leaf Area Index in Riparian Forests: Estimation with Airborne Lidar vs. Airborne Structure-from-Motion and the Societal Value of Remotely Sensed Ecological Information
Remote Sensing technology has expanded tremendously over the past few decades and has created value when integrated into environmental concepts and practices. But there is unmet potential for bolstering ecosystem services ... -
Leveraging Open Data to Support Forest Mapping, Modeling, and Policy Analysis in the Pacific Northwest, USA
Increasing access to open data can offer unprecedented opportunities to conduct and share actionable science involving forest ecology, management, and conservation. This dissertation recounts three diverse applications of ... -
LiDAR Individual Tree Detection for Assessing Structurally Diverse Forest Landscapes
Contemporary forest management on public land incorporates a focus on restoration and maintenance of ecological functions through silvicultural manipulation of forest structure on a landscape scale. Incorporating reference ... -
Modeling uncertainty in burn severity using the Composite Burn Index and remotely sensed data
Methods to link ground-based measurements of burn severity with remotely sensed data vary, and there is no consensus on the best approach. The objectives of this dissertation were to: 1) summarize methodological pathways ... -
Quantifying vertical and horizontal stand structure using terrestrial LiDAR in Pacific Northwest forests
(2014-04-30)Abstract Quantifying vertical and horizontal stand structure using terrestrial LiDAR in Pacific Northwest forests Alexandra Kazakova Chair of Supervisory Committee: Dr. L. Monika Moskal School of Environmental and Forest ... -
Reconstructing the past and modeling the future of wetland dynamics under climate change
Abstract Reconstructing the past and modeling the future of wetland dynamics under climate change Meghan Halabisky Chair of Supervisory Committee: Dr. L. Monika Moskal School of Environmental and Forest Sciences Wetland ... -
Relationships between fine root productivity and aboveground forest metrics
(2013-11-14)Understanding pools and fluxes of belowground living plant C in most ecosystems is a global priority (Clark et al. 2001). There is a pressing need for studies that address the variability of fine roots and to accurately ... -
Restoring forest resilience in the Sierra Nevada mixed-conifer zone, with a focus on measuring spatial patterns of trees using airborne lidar
Forests across the western United States experienced profound changes throughout the 20th century in response to human resource use such as logging, grazing, and mining as well as very effective fire suppression, followed ... -
The impact of climate change and topography on spatial and temporal NPP dynamics using time-series Landsat data coupled with Biome-BGC model
Understanding the trends and variations of total ecosystem net primary productivity (NPP) is critical for simulating and predicting changes in the terrestrial carbon cycle across a range of spatial and temporal scales. A ... -
Using aerial photos to produce digital surface models, otrhophotos, and land cover maps of a coastal area in Puget Sound, WA
A new method in photogrammetry (the practice of taking spatial measurements from photographs) called Structure from Motion (SfM) produces automated measurements at much lower cost than older techniques. Research has shown ... -
Using Lidar Data to Predict Photo Interpreted Attributes
Large datasets and robust workflows exist for both the photo interpretation and Lidar methodologies. Both methodologies have unique and non-overlapping strengths in describing forest conditions. Bridging the data products ...
