Riparian vegetation data downstream of Glen Canyon Dam in Glen Canyon National Recreation Area and Grand Canyon National Park, AZ from 2014 to 2019

These data were collected by the Grand Canyon Monitoring and Research Center (GCMRC) to support riparian vegetation monitoring along the Colorado River between Glen Canyon Dam and the full pool level of Lake Mead. The objectives of the GCMRC riparian vegetation monitoring program are to annually measure and summarize the status (composition and cover) of native and non-native vascular plant species within the riparian zone of the Colorado River between Glen Canyon Dam and Lake Mead, assess change in the vegetation composition and cover in the riparian zone, as related to geomorphic setting and dam operations, particularly flow regime, and collect data in a manner that can be used by multiple stakeholders and is...

Native ranges of freshwater fishes of North America

Background: The Nonindigenous Aquatic Species (NAS) Database functions as a repository and clearinghouse for the occurrence of nonindigenous aquatic species information from across the United States. The Database contains locality information on more than 1,300 species introduced as early as 1800, including freshwater vertebrates and invertebrates, aquatic plants, and marine fishes. Taxa include both foreign species and North American native species that have been translocated outside of their natural range. Locality data are derived from many sources, including scientific literature; Federal, State, and local natural resource monitoring programs; museum collections; news agencies; and direct submission through...

Field Site Locations from Phragmites Bioherbicide 2023 Field Experiment in Southeast Michigan

This dataset represents the locations of experimental plots that were used during the Phragmites Bioherbicide 2023 field experiment. To meet the criteria for selection, a site must have relatively dry soil with no standing water, have two or more large monotypic stands of Phragmites australis, and be easily accessible by vehicle. Experimental plots were created at these sites and one of four treatments were applied to each plot involving either tap water or bioherbicide.

Predicted exotic annual grass abundance in rangelands of the western United States using various precipitation scenarios for 2022

Invasion of exotic annual grass (EAG), such as cheatgrass (Bromus tectorum), red brome (Bromus rubens), and medusahead (Taeniatherum caput-medusae), could have irreversible degradation impact to arid and semiarid rangeland ecosystems in the western United States. The distribution and abundance of these EAG species are highly influenced by weather variables such as temperature and precipitation. We set out to develop a machine learning modelling approach using a lightGBM algorithm to predict how changes in annual and immediate past precipitation regimes impact the abundance of EAG in the study area. The predictive model primarily utilized edaphic and weather variables and a seed source proxy from previous years to...
