Description: Several grass and woody crops grow naturally around potholes, marshes and sloughs across the Canadian Prairies. Thisvegetation serves as a valuable habitat for wildlife, but canbecome invasive on agricultural land and a source of wild fires.This paper presents an innovative harvesting method that canrejuvenate the vegetation, while providing a useful biomass. Theprototype, based on a modified round baler and called a €˜€˜biobaler'',was used in Saskatchewan to harvest natural willowrings around marshes. It cut, shredded and baled the woodycrop in a single pass. Harvestrat es averaged 3.5 and 6.6t/h [fresh weight (FW)] on two sites of different brush density[11 and 43 t/ha of dry matter (DM), respectively]. Round baleswere typically 1.22 m wide by 1.35 m diameter they weighed onaverage 251 and 347 kg F at each site (density of 144 and 199kg FW/m3). Moisture content of harvested crop averaged 41%. The bio-baler recovered 62% of biomass (7 and 27 tDM/ha,respectively). The technology could be used to manage naturallygrowing woody shrubs, while collecting a currently neglected source of biomass.
