the upper meadow were also sampled in the lower meadow. A similarity coefficient <br />(Sorenson's) of 53.7% between the two meadows is relatively high considering that <br />values of 57.5% and 52.6% were calculated when comparing baseline communities to <br />their reference areas for the JW and MS communities respectively. It is also valuable <br />to note that of the f-ve species that had a relative cover exceeding 3% in the lower <br />meadow, ail were present in the upper meadow and all five had relative cover values <br />exceeding 3%. Only two of the seven species with a relative cover greater than 3% in <br />the upper meadow had less than 3% relative cover in the lower meadow. The fact that <br />the most important species for each meadow were shared is consistent with a <br />community being defined based on visually dominant species (page 2, Division's <br />Guidelines). The decision to sample them in the same category was therefore <br />reasonable. <br />• The meadow community was dominated by annual and noxious plant species. <br />Relative cover data indicated that bindweed (Convolvulus arvensis) was the dominant or <br />second most important species in the two sites. The annual grasses cheatgrass and <br />Japanese brome (Bromus japonicas) combined for almost a quarter of the multiple hits. <br />The most important perennial species were alfalfa (Medicago saliva) and Kentucky <br />bluegrass (Poa prarensis). No other perennial species contributed more than 2.0% <br />relative cover. The suspected disturbed nature of the community and the high <br />importance of annual and noxious species contributed to the decision not to fmd a <br />reference azea; it seemed counter-productive to match aweed-dominated community to <br />a weed-dominated reference area (which, additionally, was not evident in the <br />surrounding area). Mr. Waldron of DMG agreed and expected that standards somehow <br />related to the baseline data would be a more appropriate way of determining success for <br />this community. <br />• <br />19 <br />
