Project description

We have three main objectives:

• Determine how and where to best apply restoration methods in a catchment to achieve increased (i.e., recovered) biodiversity based on factors such as 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?
• To determine how potential complexity and organism source changes 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.
