CTAP plant and bird data can be requested by contacting David Zaya (dzaya1 [at] illinois {dot} edu).

 

CTAP plant data include ground cover estimates for vascular species, shrub frequency, tree frequency and size (dbh), and observations of other species present at a site.  Bird data include the occurrence or abundance of individual species as well as the number of species found at a particular site. 

 

Data files can be made available in multiple formats.
