Completed Projects

Characterizing vegetation dynamics in western national parks

The goal of this project was to develop satellite-based maps of changes in vegetation dynamics over time, and to test the extent to which spatial and temporal patterns of change can be used to infer the relative importance of human management and climate change on those vegetative dynamics. Read more →

Monitoring pest and fire related mortality in Oregon

We investigated the extent to which LandTrendr (Landsat Detection of Trends in Disturbance and Recovery) algorithms could meet mapping needs and lay foundations for predictive modeling of pest-related fuel loading and risk. Read more →

Coho SalmonCharacterizing landcover trends within Oregon Coast Coho Salmon habitat

This project was designed to characterize spatial and temporal forest disturbance patterns that could potentially affect the habtitat suitability for the Oregon Coast Coho Salmon. Disturbance information was mapped using trajectory-based techniques derived from annual Landsat Thematic Mapper (TM) data, merged with existing maps of seral stage. Analytical techniques focused on understanding and characterizing spatial patterns according to watershed, basin, ownership, and management regime, and temporal patterns related to changes in policy, economic drivers, and climate.

Developing protocols for remote-sensing based inventorying & monitoring (I&M) of vegetation patterns across several I&M networks of the National Park Service

A primary goal of the National Park Service’s Inventory and Monitoring program (NPS I&M) is to “monitor park ecosystems to better understand their dynamic nature and condition and to provide reference points for comparisons with other, altered environments.”  In conjunction with several networks (see below) within the NPS I&M, we developed protocols for long-term, remote-sensing based monitoring of landscape patterns and vegetation changes. Read more →

Mapping Current Conditions & Modeling the Dynamic Responses of Riparian Vegetation & Salmon Habitat in Oregon

This research integrated riparian zone mapping with dynamic models to project the response of riparian zones, stream channels and salmon habitat to natural disturbance and land-use activities. Read more →

Northern Eurasia Land Dynamics Analysis (NELDA)

The Northern Eurasia Land Dynamics Analysis (NELDA) harnessed NASA remote sensing technology and local knowledge of land-cover conditions in order to validate and improve land cover/land-cover change products for Northern Eurasia. Read more →

Integrating Remote Sensing, Field Observations, and Models to Understand Disturbance and Climate Effects on the Carbon Balance of the West Coast U.S. 

Our primary goals were to provide a regional test of the overall North American Carbon Program (NACP) strategy by demonstrating bottom-up and top-down approaches to determine the carbon balance of the West Coast of the US, and to develop global carbon cycle modeling and analysis focused on the use of remote sensing data.

Mapping Urbanization in the Snohomish Watershed, WA

To satisfy the goals of the Washington Department of Fish and Wildlife (DFW) and the Washington Governor’s Office, we are produced maps of urbanization in the Snohomish watershed during the period 1972-2004.  Read more →

Landsat Ecosystem Disturbance Adaptive Processing System (LEDAPS)

LEDAPS, a NASA-funded project to map North American forest disturbance since 1975 from the Landsat satellite record, produced comprehensive maps of surface reflectance for 1975, 1990, and 2000 for the United States and Canada. Read more 

Satellite Laser Altimetry of Forests (SLAF)

This research explored how lidar waveforms from the GLAS sensor could be used to estimate forest height and aboveground biomass over three pilot study areas: the Pacific Northwest, southeast of the U.S. and the northwestern Amazon Basin.  Read more 

Assessing Eastern North American Forest Disturbance and Regrowth: Potential from Passive Optical Remote Sensing Evaluated in the Mid-Atlantic Region

This project was funded by NASA Terrestrial Ecology Program in support of the North American Carbon Program (NACP). The Forest Cover Change Project had the following goals: Read more 

Partial Harvest Mapping Project

We collected field and photo data to support an effort to map partial harvests in central Washington. Read more 

BigFoot - Linking In Situ Measurements, Remote Sensing, and Models to Validate MODIS Products Related to the Terrestrial Carbon Cycle

The overall goal of BigFoot was to provide validation of MODLand (MODIS Land Science Team) science products, including land cover, leaf area index (LAI), fraction absorbed photosynthetic active radiation (fAPAR) , and net primary production (NPP). Read more →

Northwest Forest Plan Disturbance Mapping and Update

LARSE has a long tradition of mapping stand-replacing disturbance in Pacific Northwest forests. In support of the Northwest Forest Plan (NWFP), designated in 1994 to cover management of federal forestlands in Washington, Oregon and California within the range of the northern spotted owl, LARSE has been involved in several mapping projects.

Modeling Carbon Dynamics and Their Economic Implications in Two Forested Regions: Pacific Northwestern USA and Northwestern Russia

This research project was drafted to compare two significant forest regions, the United States Pacific Northwest and the St. Petersburg region of Russia, with the overall objective of determining the relative importance of land-use versus biogeoclimatic factors in controlling spatial and temporal patterns of carbon dynamics.

TERRA - Regional Analysis of Net Ecosystem Productivity of Pacific Northwest Forests: Scaling Methods, Validation and Results Across Major Forest Types and Age Classes

Net ecosystem productivity (NEP) is a critical characteristic of terrestrial ecosystem response to environment. Read more →

Interagency Vegetation Mapping Project (IVMP)

The Interagency Vegetation Mapping Project (IVMP) is a joint effort by the Forest Service and Bureau of Land Management to map forest structure and composition variables (quadratic mean diameter, percent canopy cover, and percent cover of broadleaves and conifers) in western Oregon and Washington using Landsat-5 TM data.

ETM+LIFE - Integration of Enhanced Thematic Mapper Plus and Lidar for Forest Ecosystems

The overall goal of this project is to provide a framework for integrating Landsat, lidar, ground, and environmental data for applications in forest ecology. Read more →

Pacific Northwest Ecosystem Research Consortium: Willamette River Basin Mapping Project (PNW-ERC)

The Pacific Northwest Ecosystem Research Consortium (PNW-ERC), funded by the Environmental Protection Agency, was created "to address specific priority environmental problems in the Northwest, while at the same time developing the ecological understanding and scientific approaches needed to implement ecosystem management on a broad scale."
