The NOSS Report.

"The Natural and Open Spaces Study (NOSS) was undertaken to provide the technical information necessary to enable informed decisions regarding the City's remaining natural areas and open spaces. The study recommends the protection of 57 natural areas city-wide." 

The Farm - The Natural Open Space Study (NOSS) report, prepared by the City of Ottawa, identifies a number of significant natural resources on or adjacent to the Central Experimental Farm site. The Arboretum ranks in the highest category for social value, reflecting the importance Ottawa residents attach to this area for its visual and natural relief, and for its contribution to the quality of life in an urban context. The NOSS study recommends protection of the Arboretum, an adjacent open water wetland habitat, two nearby watercourse reaches, and the CEF Woods near Fisher Avenue. It also provides management guidelines. (From: Central Experimental Farm Historic Site Management Plan (8 of 20) Date modified on 2019-09-17.)
