R code: Landscape- and local-level variables associated with monarch breeding occurrence and abundance at patches in Wisconsin grasslands
November 1, 2021
This code file accompanies a manuscript describing associations of monarch breeding occurrence and abundance with landscape and local characteristics at locations in northern and southern Wisconsin. Context for the study can be obtained from the manuscript (Bruce (nee Harnsberger), A.S., Thogmartin, W.E., Trosen, C., Oberhauser, K., and Gratton, C., In-Press, Landscape- and local- level variables affect monarchs at patches in Midwest grasslands: Landscape Ecology), metadata for covariate information, and comments within the code.

Landscape- and local- level variables affect monarchs in Midwest grasslands
ContextIt is estimated that over one billion milkweed stems need to be restored to sustain the eastern North American migratory population of monarch butterflies; where and in what context the stems should be placed on the landscape is key to addressing habitat deficits.ObjectivesWe assessed how the amount of appropriate habitat surrounding a particular patch of monarch habitat affects...
