Brewer's Sparrow site data


Site data from line transect surveys for Brewer's sparrow on 72 transects located on a 4105 km^2 study area in central Wyoming. Data were collected by Dr. Jason Carlisle of the Wyoming Cooperative Fish & Wildlife Research Unit in 2012. Each transect was 500 meters long. See the package vignettes for tutorials of the basic analysis.


A data.frame containing 72 rows and 8 columns. Each row represents a site (transect) surveyed. Column descriptions:

  1. siteID: Factor (72 levels), the site or transect surveyed.

  2. length: Number, the length (m) of each transect.

  3. observer: Factor (five levels), identity of the observer who surveyed the transect.

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

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

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

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

  8. shrubclass: Factor (two levels), shrub class is "Low"" when shrub cover is < 10%, "High" otherwise.


The Brewer's sparrow data are a subset of the data collected by Jason Carlisle and various 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).
