Aerial imagery for the Upper Mississippi River System (UMRS) Navigational Pool 5 drawdown follow-up was collected in true color (TC) in August of 2015 at 6”/pixel using a mapping-grade Applanix DSS 439 digital aerial camera. All TC aerial images were orthorectified, mosaicked, and compressed into a JPEG2000-format image. The TC aerial images were interpreted and automated using a genus-level 150-class Long Term Resource Monitoring (LTRM) vegetation classification. The 2015 vegetation database was prepared by or under the supervision of competent and trained professional staff using documented standard operated procedures.

The geographic information system pilot project on Pool 13 of the Upper Mississippi River System was initiated to evaluate system-wide application of various methods of capturing, processing and converting resource data. Classification schemes were developed for two data themes: land cover/land use (vegetation) and aquatic areas. Evaluation of 1:15,000 scale aerial photography indicated that (1) color infrared transparencies were essential for accurately mapping major vegetation classes and vegetation units less than 1 acre; (2) color infrared prints were essential for field work (delineating work areas on the photos and identifying in the field; (3) true color (Ektachrome) transparencies and prints were not useful...

This dataset includes quantifications of bigheaded carp DNA found in water samples collected from the Wabash River along transects at 3 sites over time. The samples were collected at 18 equidistant points in a transect across the river at each site. Samples were collected in 2013 on May 29, 30, 31, June 5, 6, 7, 8, 9, 10, 11, 16, 17, 19, 20, 21, and 22. Quantitative polymerase chain reaction (qPCR) was performed to determine the DNA concentrations in two replicates using the bigheaded carp assay defined in Merkes and others 2014.

Invasive species may vary in their seasonal distribution and abundance due to environmental conditions such as precipitation and temperature. Bigheaded carps, which include silver and bighead carp, are one such taxon of invasive species that appear to change habitats seasonally. Seasonal changes in bigheaded carp distribution may occur because of hydrological changes, water temperature changes, and spawning activities. Monitoring this seasonal dispersal and migration is important for management to control the population size and spread of the species. We examined if environmental DNA (eDNA) approaches could detect seasonal changes in the occurrence of DNA in water samples and used these approaches to calculate the...

Semi-Permeable Membrane Devices (SPMDs) were deployed for approximately 2 weeks at Palmyra Atoll during October and November, 2008. SPMDs passively accumulate organic compounds from the aquatic enviroment, and are then analyzed for various organic compounds. The deployment date, reasons for selecting the particular site, and photograph numbers as links are indicated.

An area encompassing all the National Forest System lands within the Greater Yellowstone Ecosystem (GYE) administered by an administrative unit. The area encompasses private lands, other governmental agency lands, and may contain National Forest System lands within the proclaimed boundaries of another administrative unit. All National Forest System lands fall within one and only one Administrative Forest Area.
