To understand how rapidly beaver bioengineering impacts sediment organic material accumulation, we characterized the short-term, temporal dynamics of how reintroduced beavers have influenced sediment and organic material accumulation on 1st and 2nd order streams over the past decade. Sources of beaver related organics include coarse woody debris, fecal matter, and allochthonous material. We measured sediment physical properties, and analyzed samples for weight percent carbon and nitrogen. Our temporally constrained results provide insight into the rapidity at which beavers can influence biogeochemical systems in headwater streams.
