Under Location, we include county, state, section (Sec), range (R.), 

 township (T.). and GPS-UTM coordinates (+250 m). The combination 

 of letters and numbers following the date of each photograph refers 

 to filing systems for the negatives of Shantz (original photograph), 

 Phillips (first retake), or Kay (second retake). Shantz's and Phillips* 

 original negatives are stored at the University of Arizona herbarium, 

 in Tucson. Kay currently maintains his negatives, which he intends 

 to leave to the Utah State University library, in Logan, upon his 

 retirement. 



The description provided in First Retake and Description is quoted 

 from Phillips' publication, except we removed taxonomic authorities 

 from scientific names and deleted references to other photographs. 

 Each taxonomic Description following the head Second Retake is 

 based on site visits by Klement, a highly experienced taxonomist. 

 Dominant plant genera and species under Description are listed in 

 order of their estimated relative abundance. 



It is refreshing to review the photographs and conclude that the 

 general ecological condition of the lands appears to have changed 

 little over the past 75 -plus years, with three exceptions. The first 

 exception is that the density and cover of woody plants appear to 

 have increased, particularly with respect to the Ponderosa pine. The 

 second exception concerns changes in plant community structure 

 and species composition due to human intervention (tillage, haying, 

 and road construction, for example). And the third exception is those 

 instances where nonindigenous species, particularly yellow sweet 

 clover and crested wheatgrass. have invaded sites by escaping from 

 nearby roadside restoration projects and agronomic plantings. 

 Otherwise, the changes seem subtle.
