Virtually all meadows occur as concentric zones of different vegetativecommunities beginning ata dryer edge and becoming wetter towards the center. Many of the dryer meadows are alkaline and someare also saline. Alkalineand salinemeadows are not typical by Canadian standards where meadows are more typically acidic. Probably the combination of a fluctuating water table, youthful basaltic bedrock, and usual summerwater deficit is responsible for these conditions. Chilcotinmeadows can be broadly classified according to five interrelated properties: (a) relative wetness (b) proportion and degree of decomposition of organicmatter (c) soil reaction and degree of salinity (d) depth of material to bedrock (e) proportion of grass and sedgeto woody brush Twenty-onetypes of meadows are recognized to date but for the purposeof this article only the more common and important This is a dry type meadowmade up primarily with muhienbergid, types are listed. western wheatgrass with some saltgrass (Distichlis), and Carex.
