# habitat: Blue grouse winter habitat selection data In Blossom: Statistical Comparisons with Distance-Function Based Permutation Tests

## Description

Example comparing used versus available blue grouse winter habitat described by the basal area measurements of four species of trees present in stands on winter range.

## Usage

 `1` ```data(habitat) ```

## Format

A data frame with 16 observations on the following 5 variables.

`use`

An indicator of which habitat was used by blue grouse (1) and which was available (2).

`dfir`

Basal area (m^2/ha) for Douglas-fir.

`junip`

Basal area (m^2/ha)for juniper.

`aspen`

Basal area (m^2/ha)for aspen.

`other`

Basal area (m^2/ha)for other trees.
