APPENDIX - DEMOGRAPHIC TRANSECT DATA 



These data show the performance of individual Penstemon 

 lemhiensis plants in permanent monitoring transects in 1989 and 

 1990. The following codes are used: 



A - aborted flowers (no fruit development apparent) 



B - browsed flowering stem 



C - established immature plants (rosette with <4 leaves) 



D - dead 



F - fruit 



I - inflorescence (flowering stem) 



P - predated fruit 



R - rosette (basal tuft of leaves on mature plant) 



S - seedlings (cotyledons evident or rosette <15 mm in 

 diameter) . 



The codes form a formula describing the state of each plant, 

 example, R5-I2-F17-A25 is a plant with 5 basal rosettes, 2 

 inflorescences, 17 fruits, and 25 aborted flowers.
