A Decision-Support Tool for Invasive Plant Management Under Fluctuating Great Lakes Water Levels
Water levels in the Great Lakes are fluctuating in ways that we have not seen in the past, with both historically low- and high-water levels occurring in the last decade. Expectations are that larger and more frequent water-level fluctuations will occur in response to climate change. The increased variability in lake levels has implications for the management of invasive plants found in the coastaForest Canopy Gap Dynamics: Quantifying Forest Gaps and Understanding Gap-level Forest Regeneration
Floodplain forest is a major and critical component of the Upper Mississippi River System (UMRS). The current and future condition of floodplain forest on the UMRS is receiving increased attention from managers as the forest appears to be declining and not regenerating. A primary concern is invasive reed canarygrass (Phalaris arundinacea), Dutch elm disease (Ophiostoma ulmi and O. novo-ulmi), and... - Data
Vegetation Map for the Seboeis Unit of Katahdin Woods and Waters National Monument (Vector and Tabular Data)
This project created a detailed vegetation map of the Seboeis Unit of Katahdin Woods and Waters National Monument for National Park Service managers. This is the final data covering all final products of the project related to tabular data collected during the project and vector data created from project imagery.Aerial thermal imagery of the Central Platte River Valley and bounding box annotations of sandhill cranes
Aerial thermal imagery was collected over the Central Platte River Valley, Nebraska, USA. Bounding box annotations were manually created for the purpose of machine learning tasks to automate the detection of sandhill cranes. Mosaicking of the thermal imagery was complete to assemble the individual images into a single, geo-referenced image.2020 Systemic Land Cover Data, Upper Mississippi River System (UMRS)
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to the existin2020 Systemic Imagery, Upper Mississippi River System (UMRS)
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020.

Big Oaks National Wildlife Refuge (NWR) is a 50,000 acre refuge overlaid on portions of the former Jefferson Proving Ground (JPG) in Jefferson, Jennings, and Ripley counties, Indiana. Beginning in 1996, the U.S. Fish and Wildlife Service (USFWS) began managing the area. Big Oaks NWR was established in June 2000 as an “overlay” Refuge through a 25-year real estate permit from the U.S. Army. As an o - Publications
Vegetation map for the Seboeis Unit of Katahdin Woods and Waters National Monument
The Katahdin Woods and Waters National Monument, located in the forests of central Maine, is a newly (2016) established unit for the National Park Service. To better understand the condition of lands within the monument and inform management planning, Katahdin Woods and Waters National Monument resource managers wanted better information of the vegetation present within the monument.
