E. HABITAT: Goodyera repens occurs on sites dominated by 

 Pseudotsuqa menziesii , with a well developed moss 

 layer. The habitat type as defined by Pfister et al. 

 (1977) would be considered a Picea engelmannii/Linnaea 

 borealis . However, the percentage cover of Picea 

 engelmannii and other tree species as described for 

 this type is much higher than was present in the 

 vicinity of G. repens populations. Goodyera repens 

 appeared to drop out if the percentage of Picea 

 engelmannii increased in the canopy. This appeared to 

 be due to the narrower crown shape of Picea engelmannii 

 compared with Pseudotsuga menziesii , which allowed a 

 higher percentage of light to pass through the canopy. 

 The sites are typically on cool, northerly aspects of 

 gentle to moderate slopes (5-35%) , at elevations of 

 5800-6200 feet (1770-1890 m) . Populations occurred in 

 valleys or ravines, where solar radiation was limited 

 by a horizon to the west, or on due north slopes. The 

 underlying substrate of the central Montana populations 

 is mostly Madison limestone, although G. repens is 

 generally shallowly rooted in the thick surficial 

 organic layers of the sites. 



1. ASSOCIATED VEGETATION: Goodyera repens 



populations typically occur in older forests 

 dominated by Pseudotsuga menziesii , with a well 

 developed moss layer dominated by f eathermosses 

 ( Hylocomium splendens , Pleurozium schreberi ) . 

 Other native plant species commonly associated 

 with Goodyera repens include: 



Abies lasiocarpa (subalpine fir) 

 Juniperus communis (common juniper) 

 Pinus contorta (lodgepole pine) 

 Acer glabrum (Rocky Mountain maple) 

 Cornus stolonifera (red-osier dogwood) 

 Physocarpus malvaceus (ninebark) 

 Ribes setosum (gooseberry) 

 Spiraea betulifolia (shiny-leaf spiraea)
