LAKE-SHORE. VEGETATION IN NORTH-CENTRAL COLORADO 65 
Fig. 6. Map of vegetation at Burgrass Lake, one of the Forest Lakes, a small sub- 
alpine pond at an altitude of 10,800 feet. Scattered plants of burgrass {Sparganium angusti- 
folium) at the east side near the outlet give the lake its name. Rush moor and heath 
moor, imperfectly develpped in places, could not well be shown on the map. 
Typical sedge moor has often been described (5, 7, 9). Moss moor and 
true sedge moor may be distinguished in the following quadrat records in 
which the percentage of ground covered by each kind of plant is indicated 
(tables 6 and 7). Naturally, any quadrat in a community would be different 
from every other quadrat as to minute details, but quadrat records afford 
the best means of distinguishing similar communities.
