Brownlee and Dukes Creek - Population 3
cursory or incidental
Roughly 700 ft x 15 ft
More potential habitat to survey:
Suggestions for other areas to survey:
Anywhere in the area with thin, rocky soil on ridge tops and south aspects.
Monitoring or research needs for this population:
Unsure, population overall was fair to poor for vigor, very scattered, in suboptimal habitat, with noxious weeds in the near by vicinity.
Management needs for this population:
The Forest Service needs to consult a botanist on this population before using this closed road again. The Payette National Forest plans to take a mini excavator down this road in July 2018. The onions are right on the road bed and there isn’t another access route for the range infrastructure maintenance. The Forest Service will use the road after the plants have gone to fruit and are dormant again. The bulbs are also three to six inches deep in the soil, and may be unharmed by equipment travelling on top of the soil. The population appears to be a marginal population where the plants are barely persisting. There are other, larger populations of Allium tolmiei var. persimile in the nearby and distant area. The immediate location was not thoroughly surveyed, though. The number of individuals within this population may be much higher and spread over a much larger area, as well. With all those points in mind, I don’t think the potential loss of a few individuals will have a large detrimental impact upon Allium tolmiei var. persimile’s regional presence.
Additional population comments:
Population is on the bed of an old logging road.
