To manage underused urban grassy spaces like transmission lines as tall-grass prairie habitats or other endangered ecosystems, ecologists need to know how mowing, spraying and surrounding urban lands affect species richness and numbers of plants and animals along transmission lines. I conducted surveys along 48 transmission lines in Winnipeg, Manitoba in 2007-2009 to answer these questions, and I concluded that mowing and spraying should be reduced, but not eliminated, to increase butterflies and other arthropods, resources for butterflies and other arthropods, and arthropod prey for birds. However, the amount of nearby urban land reduced plant species richness and grassland bird abundance along lines more strongly than mowing or spraying, suggesting that lines with less nearby urban land should be selected for management as grassland bird habitats. Mowing and spraying can then be reduced along these lines to benefit other species, enabling urban lands like transmission lines to contribute to conservation.

Avian point counts were conducted in tall-grass prairie fragments and adjacent grassland and agricultural matrix habitat in southern Manitoba. Bird density/abundance was compared between habitat types, while variables within prairie at local, patch or landscape level were modeled to determin avian habitat selection. Prairies and matrix grassland habitat supported the same number of species in both years, and densities of all focal bird species were the same in non-native grasslands as compared with native tall-grass prairies. Overall species richness in tall-grass prairies was mainly driven by vegetation variables. Variable responses to habitat structure and composition between avian species indicate that managing grasslands to promote heterogeneity is important to sustain a diverse assemblage of avian species. As individual species were affected most strongly by vegetation structure and richness, it follows that management of prairie vegetation through techniques such as grazing and prescribed burning could optimize habitat usability for birds.

The Yellow Quill Mixed Grass Prairie Preserve is a remnant of an endangered community that is located in southwestern Manitoba and owned by The Nature Conservancy of Canada. In 2005 and 2006, this study was conducted to investigate the effect that the currently-practiced twice-over rotational cattle grazing regime is having on the carabid beetles and spiders. This study primarily compared grazed and ungrazed treatments on three paddocks. A secondary experiment investigated whether the spring graze, fall graze, or the combination of the two had the greatest impact on the carabids and spiders. Three periods were examined in three periods each season: before grazing had begun, after the spring graze, and after the fall graze. A total of 81 species of carabids and 156 species of spiders were recorded, including potentially new provincial records (two carabid species and 20 spider species). Seventy two species of plants were recorded in the study.

The thesis begins with a notion to design a school of architecture in Saskatchewan. The context, at first, appears overwhelmingly basic: an agricultural grid superimposed on a horizontal plain, under an endless sky. This formulaic description cannot capture what it is to experience the place. Stemming from this archetypal divide between earth and sky, the character of the prairies develops through a series of pairs. Each four-part section begins by setting up a polarity; on one side, a grid, and on the other, a ghost. The intersection of these two elements is illustrated through an interface and a segment of time. With each added layer, the polarities become increasingly entwined. The school of architecture is located, conceptually, in this space of reciprocity. The physical site is an industrial wasteland near the centre of Saskatoon, bounded on the east and west sides by two sets of train tracks. A timber and masonry warehouse, constructed for the John Deere Plow Company in 1910, is located along the end of the spur line to the east. The school of architecture finds itself within this building. The view down the tracks provides a glimpse of the prairie fields; the nondescript site itself alludes to this Deleuzian smooth space beyond the city limits. Even as it precisely situates and contains itself in this physical urban context, the school of architecture internalizes the dream of the prairie landscape. It is an educational institution and an incubator for the architectural imagination.
