This report details a 2009 survey of cattail biomass and nutrient levels in the Netley-Libau Marsh to understand its role in reducing nutrient loading into Lake Winnipeg. It finds that phosphorus levels in the marsh significantly exceed provincial guidelines and estimates the potential for increased nutrient storage through plant restoration.

This report by the International Institute for Sustainable Development (IISD) evaluates the commercial-scale harvesting of cattail (Typha spp.) biomass in Manitoba, Canada, as a method for nutrient capture and the production of bioenergy and biocarbon. The project demonstrates that harvesting cattails from wetlands and water retention sites removes phosphorus and nitrogen from the watershed, reducing nutrient loading into Lake Winnipeg while providing a sustainable feedstock for solid fuels and soil amendments.

This report details the proof of concept testing (POCT) of the Canadian Biodiversity Index (CBI), a tool designed to consistently assess and convey biodiversity status and trends across Canada. The testing applied the CBI framework to two distinct ecounits—Netley-Libau Marsh in Manitoba and Banks Island in the Northwest Territories—to evaluate the index's methodology, the effectiveness of its normalized scoring scale, and the challenges of data availability.
