SP Myers + 1977 Vegetation notes: River bar association At Karook on Meade River, N. Slope Borough, Alaska 26 Aug Today sampled the only few patches of river bar we have on Horseshoe (T7). I doubt that we have ever recorded birds within. Much of the association appears to be the Salix alaxensis understory trailing out into a bar - then it is heavy with Equisetum + there are scattered S. glauca and S. alaxensis between rocks. But the presence of a thick stand of Dypsis Ascherii, considerable Carex aquatilis, thick patches of Carex membranacea and a stiviparous Poa (aurita?). also Juncus articus and Eriophorum russeolum + wilhelmsia I deduced all of these plants to lie in Vera K's RB3, what she calls Eriophorum - Wilhelmsia.
