2. TOPOGRAPHY AND SOILS: Populations of Balsamorhiza 

 macrophvlla in the Cinnamon Creek vicinity occur on 

 open east-facing slopes, from 2300 m. (7100 ft.) to 

 2500 m. (7400 ft.)* The slope supporting the main 

 population is gentle (8-15%) . The soil is loamy 

 and without rocks. The plant community indicates a 

 moderately moist site. Subpopulations are found on 

 45% slopes where the soils are rockier with more 

 clay, and tend to be more closely associated with 

 Douglas-fir trees or saplings which are scattered 

 in the openings. 



F. POPULATION DEMOGRAPHY AND BIOLOGY 



1. REPRODUCTIVE BIOLOGY: Balsamorhiza macrophvlla 

 reproduces by seed. Seeds give rise to plants 

 producing large taproots and which become 

 relatively long-lived perennials. 



2. POPULATION SIZE AND CONDITION: The main population 

 of Balsamorhiza macrophylla at Cinnamon Creek 

 consists of well over 1000 individuals.- The 

 subpopulations together total around 100 plants. 



It was estimated that at least 10% of the total is 

 made up of young plants, i.e., those in leaf only 

 and with unbranched crowns. Mature plants were 

 vigorous.
