dc.description.abstract At the University of Manitoba's Carman research station two, 10 m x 10 m sites were surveyed for the presence or absence of weed seedlings at a scale of 10 cm x 10 cm, in 1998 and one repeated site in 1999. These sites contained wild oat, green foxtail, and barnyardgrass. Visual maps were created which provided an overall view of the species associations. Statistical analysis of the three species was performed using unadjusted Chi-square analysis, and autocorrelation was adjusted for using the Random Patterns and Patch Model tests. Spatial patterns cannot be used to prove which process is responsible for their formation, but can be used to suggest possible processes which led to their formation. Wild oat and green foxtail were found to be significantly negatively associated at sites 1 and 2 in 1998. Wild oat and barnyardgrass were found to be significantly negatively associated at sites 1 and 2 in 1998, and significantly positively associated at site 1 in 1999. Green foxtail and barnyardgrass were found to be significantly positively associated at site 1 in 1998 and 1999. A replacement series experiment revealed that wild oat was more competitive than green foxtail or barnyardgrass, and that green foxtail and barnyardgrass were relatively equal competitors.
