MUTUALISM: As with most orchids, the seed of 

 Goodyera repens consists of an immature 

 embryo and limited food reserves. The seed 

 germinates into a protocorm and development 

 of the protocorm into a seedling is dependent 

 on forming a mutualistic association with 

 soil fungi, usually Rhizoctonia qoodyerae- 

 repentis (Peterson and Currah 1990) . This 

 mycorrhizal relationship increases nutrient 

 uptake and results in a higher growth rate 

 (Alexander and Hadley 1984) . 



2. ABIOTIC INTERACTIONS 



Fire: Due to the habitat requirements of 

 this species, populations are not likely to 

 respond well to fire. In the fall of 1990 a 

 fire burned through the Hay Coulee (006) and 

 Sage Creek (007) populations. Observations 

 of these sites should be made in 1991 to 

 determine if G. repens is still present in 

 any of patches of unburned timber as occurred 

 at Sandpoint Creek (001) . Burned areas are 

 not likely to support G. repens populations. 



H. LAND OWNERSHIP 



Seventeen of the 18 occurrences of Goodyera repens 

 in Montana are on land managed by the U.S. Forest 

 Service; the other site is in Glacier National 

 Park. Specific information for each occurrence is
