Project summary

Edit project overview to modify the project summary.

Goals • Remove 480 kg P per year – equals ¾ of the total Phosphorus loading to Kul Lake • Remove 18 tons N per year or 114 kg/N/ha. Per year • Stoppage of vegetation cutting and dredging • Removal of all dams/weirs in the entire watershed • Ensure habitat for the orchid Coralroot (Corallorhiza trifida) and Western marsh orchid (Dactylorhiza majalis) • Improve habitat for the European brook lamprey (Lampetra planeri) and Eurasian otter (Lutra lutra) • Open the area to the public for recreation – 37 km of trials

Restoration activities in the first 65 hectares Restoring 1.3 km of stream Raised the stream bed 50 – 80 cm Crushed/removed 25 drain systems and 7 ditches Spawning grounds every 20 meters in the stream – 650 m3 gravel 15.2 hectares of permanent/semi-permanent wetlands 8.5 hectares of seasonally flooded wetlands 6 hectares of seepage wetlands from removing drains Area is fenced to allow grazing over entire area – special agreements between land owners
