Local- and landscape- scale effects on biodiversity after stream restoration.

The BioRest project focuses on restored streams in the Vindel River catchment in northern Sweden, which were previously channelized for timber floating. We have three main objectives:

  • To determine how and where to best restore in a catchment to achieve increased (i.e., recovered) biodiversity based on morphologic complexity, landscape heterogeneity, and organism source,
  • To determine which factor (or set of factors) has the greatest effect on biodiversity of the ‘entire’ community (i.e., fish, macroinvertebrates, macrophytes, and riparian vegetation): morphologic complexity, restoration method, time since restoration, or organism source, etc.,
  • To determine how potential complexity and organism sources change throughout the catchment and in which parts of the catchment we expect to achieve greatest (or lowest) biodiversity,

The BioRest project is run by researchers at the Department of Ecology and Environmental Science at Umeå University and is funded by a grant from the Swedish EPA (Naturvårdsverket) and the Swedish Research Council Formas.
