An R package for sage grouse management

 

Utilities developed in support of the USDA-NRCS Sage Grouse Initiative (SGI)

 

Current functions include (click on function for tutorial):

 

    breeding.density - Calculates breeding density areas base on population counts/density and spatial point density

 

    fence.collision - Calculates sage grouse fence collision risk following methods presented in Stevens et al., (2013)

 

    tri - Implementation of the Riley et al (1999) Terrain Ruggedness Index

 

You can install the windows binary package at the R commandline using:

> install.packages("http://s3.amazonaws.com/sagegrouse/SGITools_0.1-0.zip ", type="binary", repos=NULL)

 

You can install the linux or mac packageat the R commandline using:

> install.packages("http://s3.amazonaws.com/sagegrouse/SGITools_0.1-0.tar.gz ", repos=NULL)
