Three replicated point counts of 10 min each, out to a maximum distance of 100 m, were conducted in each spring between 1999 and 2018 at a total of 373 locations in the Hubbard Brook Experimental Forest in New Hampshire. This data set contains the data for the following 13 species:
AMRE - American Redstart
BAWW - Black-and-white Warbler
BHVI - Blue headed Vireo
BLBW - Blackburnian Warbler
BLPW - Blackpoll Warbler
BTBW - Black-throated Blue Warbler
BTNW - Black-throated Green Warbler
CAWA - Canada Warbler
MAWA - Magnolia Warbler
MYWA - Myrtle Warbler
NAWA - Nashville Warbler
OVEN - Ovenbird
REVI - Red-eyed Vireo
data("HubbardBrook")HubbardBrook is a list with 4 elements:
a sites x replicates x years x species array of counts, the number of unique individuals detected within 50m of the point count location.
a data frame with rows for 373 sites and the following columns:
PlotID : a numeric site identifier.
Longitude : the longitude of the point (WGS84); 2 sites have missing data.
Latitude : the latitude of the point (WGS84); 2 sites have missing data.
Elev : the elevation of the point, m.
Aspect : aspect of the sample location (degrees).
Slope : slope of the sample location.
Forest : general forest cover type of sample location.
a sites x replicates x years array of ordinal day of count (1 Jan = 1); NA entries occur when surveys were not carried out.
a sites x replicates x years array with the start time of the survey, hours after midnight.
