The production of wild rice in the natural lakes and streams of Saskatchewan's north has become a viable and rapidly growing industry over the last few decades. However, little information exists regarding the plant's growth and habitat preferences in this area. At the end of the 1986 growing season, plants and environmental conditions were examined in twenty established stands of wild rice located across the main wild rice growing region of the province. In analysis, the growth of the wild rice plants proved to be highly variable across the province. Almost no spatial trend was seen in plant morphology or development across the region. However, stand density decreased significantly towards the north and west, and the estimated maximum yield of seed for each site decreased significantly towards the west. In terms of relationships between the environmental factors and plant morphological characteristics measured, significant correlations were found only between water depth and pH and mature main culm height and diameter, indicating that as the values for these two factors increased, the culms were longer, and in the case of water depth, also thinner.
