thrasherSiteData - Sage Thrasher site data.

Description

Point transect data collected in central Wyoming from 120 points surveyed for Sage Thrashers by the Wyoming Cooperative Fish & Wildlife Research Unit in 2013. See package vignettes for tutorials of the basic analysis.

Format

A data.frame containing 120 rows and 6 columns. Each row represents a surveyed site (point). Column descriptions:

1. siteID: Factor (120 levels), the site or point surveyed.

2. observer: Factor (six levels), identity of the observer who surveyed the point.

3. bare: Number, the mean bare ground cover (%) within 100 m of each point.

4. herb: Number, the mean herbaceous cover (%) within 100 m of each point.

5. shrub: Number, the mean shrub cover (%) within 100 m of each point.

6. height: Number, the mean shrub height (cm) within 100 m of each point.

The Sage Thrasher data are a subset of data collected by Jason Carlisle and field technicians for his Ph.D. from the Department of Ecology, University of Wyoming, in 2017. This portion of Jason's work was funded by the Wyoming Game and Fish Department through agreements with the University of Wyoming's Cooperative Fish & Wildlife Research Unit (2012).
