Carcass distance example data set

Description

Example data set of carcass distance found during searches under wind turbines.

Usage

data(carcassDistance)

Format

A data frame with 56 rows and 6 variables:

season

The season in which that carcass was found.

plotType

The plot type (either FULL or RP) that was being searched when the carcass was found.

proportionTurbineType

The proportion of turbines that have that plot type. For plotType=FULL the value is 0.1 and 0.9 for plotType=RP

.

distanceFromTurbine

Meters, carcass distance from the turbine.

compassBearingDegree

Degrees, the compass bearing from the turbine to the carcass location. Zero degrees is north, 90 degrees is east, etc.

probabilityDetection

The summarized probability of detection from the bias trial information.

Details

The fictitious wind farm has 100 turbines. For 90 turbines the search plot consists of the turbine pad and the road out to 100 meters (RP = road and pad). The remaining 10 turbines had full plots (FULL) that are circular with a radius of 100 meters. The wind farm was searched during two seasons: Spring and Fall.

The example carcasses are all the same size class (bats).

Bias trials are also done to account for searcher efficiency and carcass removal. These results are summarized as a probability of detection in the data set.
