SR1 How is mountain vegetation affected by reindeer grazing?

Are reindeer harming the mountain vegetation of Northern Scandinavia? Or is their grazing, on the contrary, essential for maintaining the diversity of the montane flora? Opinions on this issue have been divided over the years, but Mistra EviEM has now conducted a systematic review that attempts to achieve unequivocal answers.

SR2 How effective are wetlands for nitrogen and phosphorus removal?


In recent years, many wetlands have been constructed or restored in order to absorb nutrients from watercourses. But how much nutrients do such wetlands actually remove? EviEM has reviewed the available evidence on this subject.

SR3 Can biomanipulation improve water quality in eutrophicated lakes?


Reducing the stocks of zooplankton-feeding fish such as roach and bream can be a way to curb algal blooms and similar problems in eutrophic lakes. In Sweden, the method has only been tried in a few casesEviEM has assessed how useful it is.

SR4 How does farming affect the organic carbon content of arable soils?


Agricultural land has the potential to store carbon. EviEM has mapped out the evidence relating to how different farming methods affect the amount of organic carbon in arable soils.

SR5 Have the phase-outs of PFASs affected concentrations in the environment?


Many poly- and perfluorinated alkylated substances (PFAS) are toxic and persistent, and production of some of these chemicals is now being phased out. EviEM has no studied how this has affected PFAS concentrations in the environment.

SR6 How is biodiversity influenced by the management of forest set-asides?


Should forests set aside for conservation or restoration be left untouched, or is active management required if their biodiversity is to be preserved? EviEM has assessed the scientific evidence on this issue.

SR9 Roadside management and the diversity and dispersal of species


Many species that previously associated with meadows and pastures now thrive on roadsides. EviEM has performed a systematic review of how the biodiversity of roadsides is affected by various kinds of management.

SR10 How does tillage intensity affect soil organic carbon (SOC)?


Reducing the intensity of tillage of arable land is a common environmental management practice for conserving carbon in the soil, but the quantitative impacts of these practices is not well understood. EviEM is undertaking a systematic review of studies investigating the impacts of tillage on soil organic carbon.
