Vegetation survey data collected in the summers of 2012 and 2014 by Itiya Aneece at the Blandy Experimental Farm (BEF) in north-central Virginia as part of her PhD dissertation. Vegetation was surveyed in four main study areas at BEF: northeast (NE) and southwest (SW) successional fields, Lake Arnold (LA), and a strip of land near the northeast successional field (NEB). The NE and SW successional fields were in various stages of succession: early (E), mid (M), and late (L), which follow NE and SW in the Plot code. Several 5m x 5m plots were established in each field, and vegetation surveys were conducted at 0.5m intervals within each plot at ground, understory, and canopy-level using the dowel method. The relative...

The Bureau of Land Management's National Invasive Species Information Management System (NISIMS) is designed to collect field data and store it in a standard database to allow for data sharing and reporting at the local, state and national levels. At this time, the system reports and tracks weed infestations only, Future versions of the system will report and track infestations by all taxa including weeds, birds, fish, and algae. The system also reports and tracks treatments of these invasive weed species infestations on public lands. The tools are based on the use of the BLM system of Enterprise Geographic Information System (EGIS) Architecture approved nationally in 2003. It also depends on the Geospatial Services...
This data product contains the quality-controlled, native sampling resolution data from NEON's breeding landbird sampling crosswalked to Darwin Core. Breeding landbirds are defined as “smaller birds (usually exclusive of raptors and upland game birds) not usually associated with aquatic habitats” (Ralph et al. 1993). The breeding landbird point counts product provides records of species identification of all individuals observed during the 6-minute count period, as well as metadata which can be used to model detectability, e.g., weather, distances from observers to birds, and detection methods. The NEON point count method is adapted from the Integrated Monitoring in Bird Conservation Regions (IMBCR): Field protocol...
Species occurrence records for native and non-native bees, wasps and other insects collected using mainly pan, malaise, and vane trapping; and insect netting methods in Canada, Mexico, the non-contiguous United States, U.S. Territories (specifically U.S. Virgin Islands), U.S. Minor Outlying Islands and other global locations with the bulk of the specimens coming from the Eastern United States often from Federal lands such as USFWS, NPS, DOD, USFS. Some records also contain notes regarding plants or substrates from which insects were collected or that were present and/or in flower at the time the insects were collected. Unless otherwise noted, taxonomic determinations (identifications) were completed by Sam Droege...

A study commissioned by the Utah Division of Water Quality and the Colorado Water Quality Control Division. Study was carried out by Utah State University. The overarching goal of the study was to conduct a comprehensive search and synthesis of existing records on the historical and current presence of ammonia-sensitive freshwater mussels (Superfamily Unionoidea) and non-pulmonate snails (Valvatidae, Hydrobiidae) in Utah and Colorado. In addition to these targeted species, other species belonging to Class Bivalvia and freshwater Gastropoda were also included. Though they were not actively sought during record searches, occurrence of non-native species such as the New Zealand mud snail (Potamopyrgus antipodarum),...
