Reference:Brayshaw (1976), Paysen et al. (1980).
Comments:Willow stands may or may not be dominated by a single species. If no dominant willow is present at low elevations, then place the stands in the Mixed willow series. Montane and subalpine willow stands are placed in separate classes since different willow species are restricted to those elevations [see Montane wetland shrub habitat, Subalpine wetland shrub habitat]. Stands of Hooker willow have environment conditions similar to alder, cottonwood and other willow series [see Black cottonwood series, Black willow series, Fremont cottonwood series, Pacific willow series, Red alder series, Red willow series, Sitka willow series, White alder series].
Plot based descriptions:Duebendorfer (1989) defines a Hooker willow association [as Woody hollows] on coastal dunes in Humboldt Bay area, Imper & Sawyer (1987) a Hooker willow/ California blackberry association [as Willow scrub] at Table Bluff Ecological Reserve, NDDB has data for Humboldt Co. o-NorCo.
