A widely used method for reducing the input of nutrients into freshwater and marine environments is to allow contributing water to pass through a created or restored wetland. Mistra EviEM has assessed the evidence and concluded that this intervention generally works well. The variation between wetlands is however large, and to obtain significant effects it is important to carefully consider where and how the wetland is constructed.
Should protected forests be left untouched, or is active management required to keep their biodiversity intact? We have mapped the scientific evidence on this issue.
How are the early life stages of fish impacted by various human disturbances in shallow coastal nursery habitats? EviEM conducts a systematic review of the evidence.
Buffer strips (permanently vegetated land surrounding agricultural fields) are used to reduce various impacts of intensive farming. EviEM will now review their effects.
EviEM has initiated a systematic review of how species diversity and species dispersal along roadsides are affected by various kinds of management.
