North American Breeding Bird Survey Dataset 1966 - 2019

The 1966-2019 North American Breeding Bird Survey (BBS) dataset contains avian point count data for more than 700 North American bird taxa (species, races, and unidentified species groupings). These data are collected annually during the breeding season, primarily in June, along thousands of randomly established roadside survey routes in the United States and Canada. Routes are r

Water levels (November 11 2016 through November 11 2017) for four wells: from upland to marsh, Moneystump Marsh, Blackwater National Wildlife Refuge, Maryland

Water levels in meters from four wells in Moneystump marsh at Blackwater National Wildlife Refuge, MD. Two wells are located in the upland forest; one well is located in the marsh-forest transition zone (ecotone); and one well is located in the marsh. Water depth of the adjacent creek is reported in meters. Data covers the time span from November 11 2016 - November 11 2017. Pressure tra

Time and Distance of Detection and Stop Locations along North American Breeding Bird Survey routes within the Gulf Coastal Plains & Ozarks Landscape Conservation Cooperative.

These data identify the time (0-1 min, 1-2 min,or 2-3 min) and distance (≤50 meters, >50 meters) category when birds were first detected during 3-minutes point counts at stop locations associated with North American Breeding Bird Survey routes or route equivalents that were surveyed on dates between 2009 and 2016 and provide point location coordinates of stop locations alo

Area of Occupied Habitat within the Mississippi Alluvial Valley Bird Conservation Region

Values for area of all occupied habitat were only obtained for species whose occupancy models predicted a marked proportion of the species' population was likely present in non-forest habitats.

Area of Sustainable Forest Habitat within the Mississippi Alluvial Valley Bird Conservation Region

Values for area of sustainable forest habitat for each species were obtained as the predicted occupied proportion of each 900 square meter pixel (i.e., occupancy probability x 900) within all forest patches deemed large enough to harbor a sustainable population of the species. The area required for a sustainable population of each species was derived from credible intervals associated with

Predicted Avian Species Occupancy within the Mississippi Alluvial Valley Bird Conservation Region

Values for area of occupied habitat by each species were obtained as the predicted occupied proportion of each 900 square meter pixel (i.e., occupancy probability x 900) for all habitats, except permanent water, within the Mississippi Alluvial Valley Bird Conservation Region.

Light intensity data (October 1 2015 through September 2019) for upper sensors: in the control treatment, Moneystump Marsh, Blackwater National Wildlife Refuge, Maryland

Light intensity levels in lux from upper sensors in Moneystump marsh at Blackwater National Wildlife Refuge MD. There are 25 light sensors all located in the control treatment area. Five sensors are located in the lowest elevation (marsh), five located in the upper marsh, five located in the marsh-forest transition zone (ecotone), five located in the lower forest, and five located
