MEADOWS OF THE LOWER MONTANE REGION 
A comparison of the meadows of Boulder Park with those of 
the lower montane region shows that, in the main, the same plants 
are present but that the predominant plants in the lower meadows 
become secondary or may even be absent from the meadows of the 
park. At lower altitudes, introduced plants have supplanted 
largely the native species and have often become dominant as the 
following lists show: 
Trifolium-Poa Society—Trifolium repens, T. pratensis, Tium 
alpinum, Fragaria glauca, Potentilla pulcherrima, Achillea lanulosa, 
Juncus balticus montanus, Dasiphora fruticosa, Phleum pratense, 
Carex festiva. 
Trifolium-Phleum Society.—Trifolium repens, Phleum pratense, 
Trifolium pratensis, Campanula petiolata, Fragaria glauca, Gerani- 
um nervosum, Tium alpinum, Achillea lanulosa, Taraxacum Taraxa- 
cum, Rudbeckia flava, Deschampsia caespitosa, Carex festiva. 
The higher subalpine meadows differ from the meadows of the 
montane zone in general appearance. Many of them have a 
grayer aspect due to the presence of sages and the greater hoariness
