Abstract

Previous workers have suggested that reproduction by seedling establishment is less important in the maintenance of tundra vegetation than in temperate areas, but few quantitative data are available. Seedling densities were studied at 11 tundra sites in or near disturbed and undisturbed cottom grass tussock tundra in Alaska, and numerous seedlings were found. Examination of seedling age structures suggests that at least Ledum palustre and probably also Empetrum nigrum do replace themselves by seed in undisturbed tundra. Seedling densities vary greatly depending on the substrate available for establishment.
