Notes | Red alder fixes nitrogen, and in the fall and winter it sheds nitrogen into coastal streams. The result is that many coastal streams have at certain times of the year nitrogen levels that are unacceptably high, according to conventional environmental standards. Current nutrient models for Oregon coast streams fail to adequately account for this natural process. “Our results provide evidence, at a regional scale, that background sources and processes cause many Coast Range streams to exceed proposed nutrient criteria, and that the prevalence of a single tree species (N-fixing red alder) exerts a dominant control over stream N concentrations across this region.” (from the Abstract) |
