F. POPULATION DEMOGRAPHY AND BIOLOGY 



1. PHENOLOGY: Like other members of the genus, it flowers in 

 August until frost. 



2. POPULATION SIZE AND CONDITION: At the Garfield County 

 collection site for this species, it is reported as 

 "frequent". Since it can have multiple stems from the 

 caudex, the observed number of flowering stems does not 

 necessarily represent the number of genetically distinct 

 individuals . 



3. REPRODUCTIVE BIOLOGY: Species in this genus are wind- 

 pollinated and have seeds that disperse by wind. Few- 

 flowered goldenrod ( Solidaqo sparsif lora ) is one of many 

 goldenrods that reproduce vegetatively by rhizomes, forming 

 clonal clumps. 



G. POPULATION ECOLOGY 



1. BIOLOGICAL INTERACTIONS 



a. COMPETITION: Unknown. 



b. HERBIVORY: Galls which reduce the vigor but do not kill the 

 plants are ubiquitous in the genus; some are species- 

 specific . 



H. LAND OWNERSHIP: Unknown. 



I. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS 



1. THREATS TO CURRENTLY KNOWN POPULATIONS: Unknown. 



2. MANAGEMENT PRACTICES AND RESPONSE: Unknown. 



SUMMARY: Few-flowered goldenrod f Solidaqo sparsiflora ) is 

 recommended for watch designation by BLM in the Big Dry and 

 Billings Resource Areas, Of all the current state plant species 

 of special concern, it is the most likely to have potential 

 habitat on BLM-administered lands in the study area. However, 

 the 1993 fieldwork in the study area was curtailed before this 

 species came into flower.
