METHODS: At each of the three sites described 

 above, a piece of re-bar approximately four feet 

 long was driven into the center of a plot to a depth 

 of two feet and painted bright orange. Plot radii 

 varied depending on the density of plants at a site, 

 but ranged from 15 (4.6 m) to 39 feet (11.9 m) . A 

 measuring tape was hooked over the center pin and 

 held at about 6 inches from the top by a knot. 

 Starting at north, the direction (in degrees) and 

 distance (in feet and inches) to the first plant 

 from the stake was recorded, along with the 

 phenological status of the plant (and hence around 

 in a circle v/ithin the specified radius until all 

 plants were recorded) . Plants were placed in size 

 classes that appeared to best relate to age. These 

 included: 



R = Rosette 



Rs = small rosette, 1 whorl of basal leaves 

 Rm = medium rosette, 2 whorls of basal leaves 

 Rl = large rosette, > 2 whorls of basal leaves 



P = Plant that has bolted. 



Ph(x)= Plant with (x) number of open, 

 flowering heads 



Pb(x)= Plant with (x) number of closed heads 

 (involucral bracts completely 

 enclosed flowers) 



Dead - a dead stem from the previous year 



Thus, a plant that had three flowering heads and 

 three unopened heads would be recorded as Ph3b3 . 

 Ph(x)b(x)h(x)b(x) indicates a plant with more than 

 one flowering stem per rosette.
