Project summary

Edit project overview to modify the project summary.

This project aimed to:

(1) Remove 480 kg P per year – equals ¾ of the total Phosphorus loading to Kul Lake; (2) Remove 18 tons N per year or 114 kg/N/ha per year; (3) Stoppage of vegetation cutting and dredging; (4) Removal of all dams/weirs in the entire watershed; (5) Ensure habitat for the orchid Coralroot (Corallorhiza trifida) and Western marsh orchid (Dactylorhiza majalis; (6) Improve habitat for the European brook lamprey (Lampetra planeri) and Eurasian otter (Lutra lutra; and (7) Open the area to the public for recreation – 37 km of trials.

The restoration activities in the first 65 hectares included:

(1) Restoring 1.3 km of stream (2) Raised the stream bed 50 – 80 cm (3) Crushed/removed 25 drain systems and 7 ditches (4) Spawning grounds every 20 meters in the stream – 650 m3 gravel (5) 15.2 hectares of permanent/semi-permanent wetlands (6) 8.5 hectares of seasonally flooded wetlands (7) 6 hectares of seepage wetlands from removing drains (8) Area is fenced to allow grazing over entire area – special agreements between land owners
