azotobacter is a genus of usually motile, oval or spherical bacteria that form thick-walled cysts and may produce large quantities of capsular slime. they are aerobic, free-living soil microbes which play an important role in the nitrogen cycle in nature, binding atmospheric nitrogen, which is inaccessible to plants, and releasing it in the form of ammonium ions into the soil (nitrogen fixation). in addition to being a model organism for studying diazotrophs, it is used by humans for the production of biofertilizers, food additives, and some biopolymers. the first representative of the genus, "azotobacter chroococcum", was discovered and described in 1901 by the dutch microbiologist and botanist martinus beijerinck. "azotobacter" species are gram-negative bacteria found in neutral and alkaline soils, in water, and in association with some plants.

at and in the area below the lake, mixed forests of ponderosa pine ("pinus ponderosa"), red fir ("abies magnifica"), white fir ("abies concolor"), lodgepole pine ("pinus contorda"), incense cedar ("libocedrus decurrens") and alder can be found. alders play a particularly important role, as alders establish symbioses with the nitrogen-fixing actinobacteria ("frankiella alni"). this bacteria converts atmospheric nitrogen into soil-soluble nitrates which can be utilised by the alder, and favorably enhances the soil fertility generally. alders benefit other plants growing near them by taking nitrogen out of the air and depositing it in the soil in usable form; fallen alder leaves make very rich compost. "picea breweriana" exists in a few small locations on the igneous slopes behind the lake. other deciduous trees at lower elevations in the area may include such species as bigleaf maple, vine maple, black oak and pacific dogwood.
