Wetland restoration

Pro­ject and ob­jec­ti­ves

Jämt­land coun­ty coun­cil’s pro­ject “Li­fe to ad(d)mi­re” aims to resto­re fi­ve Na­tu­ra 2000 wet­land are­as by bloc­king dit­ches and cle­a­ring ve­ge­ta­tion. The fi­ve are­as con­sist of bogland with dit­ches. They will be resto­red to their ori­gi­nal sta­te by bloc­king the dit­ches with wa­ter­tight dams and re­tur­ning st­reams which ha­ve been st­raigh­te­ned out to their ori­gi­nal me­an­de­ring cour­ses.

De­scrip­tion

Ge­o­sig­ma has car­ri­ed out a hydro­lo­gi­cal ana­ly­sis in or­der to eva­lu­a­te the risks in­vol­ved in the resto­ra­tion pro­ject, as­sess the ef­fects and con­se­qu­en­ces of the plan­ned me­a­su­res and iden­ti­fy su­i­tab­le methods of resto­ring the hydro­lo­gy of the are­as to its ori­gi­nal sta­te be­fo­re the dit­ches we­re dug. Among other things, this has in­vol­ved pro­po­sing sys­tems and methods for dam­ming the di­kes and re­tur­ning the st­reams to their me­an­de­ring cour­ses.
