Bluenose-East Caribou Herd 2000 Data

Description

Population size of the Bluenose-East caribou herd (Northwest Territories, Canada) from a postcalving survey in June-July 2000.

Usage

data(BEH00)

Format

16 by 2 numeric matrix, with the following columns:

xi

number of radio-collared animals in the detected (photographed) groups

gni

size of the detected groups

Details

During this survey, 33 collars were active (Patterson et al. also made calculation considering that 30 collars were active because 3 caribou were never located after collaring).
23 collars (70%) were photographed among the 16 detected groups.

Note

This data set excludes the six groups without radio-collared animal from Table 1 of Patterson et al. (2004) since they cannot be included in the estimates of the total population size.

For the last three groups, the size gni has been modified according to what Patterson et al. (2004) did (38% of what appears in Table 1).
