Abstract Little research had been made on the problems caused' by vegetation growth within an urban environment, lens attention had been given to the problem of weed and. brush fires and their impact upon a community. Reluctance to approach this problem was based on the fact that weed fires, singularly and collectively, did not cause much damage to property as was shown in the chosen study area of Denver, Colorado* However, in terms of the impact upon a city*s fiscal resources, such money was spent responding to find' extinguishing over seventeen thousand' fires between 1934 and 1967*. This represented an average of five hundred fires per year* The purpose of this study was not to determine the dollar coat of weed fires in Denver, Colorado, for that inquiry may come later* The purpose was to examine the more Quantitative aspects of fires in regard to their distributional characteristics in a time and space framework. The lack of prior investigation of the problem demanded that a foundation study be made. In studying the characteristics of weed fires, several hypotheses were made prior to and during the investigation. Theories were presented which attempted to explain or relate fire characteristics to climate, population, end land use in Denver, These theories were tested for accuracy, appropriateness, and significance after a brief account of Denver's geographic setting was presented. Testing the theories on which of the geographic variables were related to the occurrence and location of fires, and the analysis of the finding's, was accomplished by using both statistical and cartographic techniques* The statistical analysis used coefficients of correlation and Student*s t significance tests, From the results of analyzing the temporal and spatial distributional aspects of weed fires with regard to the tested theories, several conclusions were drawn, Statistically, weed fires did not have any relationship with changes in precipitation, temperature, and other climatic variables* Statistically* there was no relationship between the location of weed fires and the distribution of people and their age' and income characteristics. Statistically, the location of weed fires' did not show any connection with the amount and" location of parcels of vacant land, The lack of any statistical validation of the theories was caused by: (1) eontparing variables with completely different time dimension characteristics, (2) using predetermined areal units for comparisons of data, and (3) attempting to isolate one verifiable from a group of inter-relating? and inter-dependent variables* By using cartographic techniques, and by relying1 on the empirical knowledge of Individuals and agencies who had encountered the problems of urban weed fires, it was concluded that all of the variables that were tested together, and perhaps others, were closely associated with the occurrence and location of weed fires*
