Comments:In The Jepson Manual , mountain alder is treated as a subspecies ( Alnus incana ssp. tenuifolia ) of a widespread North America species. The elevational and regional ranges of the two montane alders, mountain alder and Sitka alder ( Alnus viridis ), differ in California. They rarely occur in the same stand [see Sitka alder series]. Stands of the Montane wetland shrub habitat and Subalpine wetland habitat occur in similar conditions. Mountain alder tolerates cooler and shadier riparian situations than most willows. Keeler-Wolf (1990e) presents qualitative descriptions at Soda Ridge candidate RNA, Feidler et al. (1986) at Green Island Lake candidate RNA in Butte Co., Keeler-Wolf (1990e) at Mud Lake RNA in Plumas Co. m-CasR; at Onion Creek in Placer Co. m-SN.
