sikadeer: Sika deer pellet data from southern Scotland

In Distance: Distance Sampling Detection Function and Abundance Estimation

Sika deer pellet data from southern Scotland

Description

Because sika deer spend most of their time in woodland areas, abundance estimates are based on pellet group counts. Line transect methods were applied to estimate deer pellet group density by geographic block.

Format

A data.frame with 1923 rows and 11 variables.

• Region.Label stratum labels

• Area size (ha) of each stratum

• Sample.Label transect labels

• Defecation.rate rate of dung production per individual per day

• Defecation.rate.SE variability in defecation rate

• Decay.rate time (days) for dung to become undetectable

• Decay.rate.SE variability in decay rate

• Effort transect length (km)

• object object ID

• distance perpendicular distance (cm)

• Study.Area study area name

Details

Data presented here are from the Peebleshire portion of the study described by Marques et al. (2001).
