This study of wilderness areas in Scotland traces the changing concept of wilderness as it has evolved in response to the particular conditions of Scotland's physical geography and land use history; it describes, and broadly delimits, the land area which might at present be defined as wilderness; and it analyses the process by which this land has come to be recognised as the resource for a distinctive form of recreation. On the basis of data obtained from a large-scale questionnaire survey, the physical and perceptual attributes of this recreational use are discussed in detail, moving from the social characteristics and activity patterns of visitors to their motivations and their attitudes to wilderness areas and their qualities. As comparative background the discussion of the wilderness concept is set first against the context of evolving attitudes in Western Europe up to the Romantic Revolution of the eighteenth century; second, against the experience of the United States of America, where wilderness has attained its highest level of expression as a concept, and its greatest extent and importance as a form of land use for conservation and recreation; and third, against a brief review of the current status of wild land throughout the modern world. The study's main conclusion is that despite the widespread modification of its character by man, the Scottish wilderness retains some of the physical, and many of the perceptual, attributes and recreational values of absolute wilderness, and that these explain the high level of commitment of recreational users of the land. Some suggestions are offered for an approach to management, and for further research, which may promote the conservation of these values.

A continental-scale study of historic wildfire data within and across ecoregion provinces was conducted and geographical gradients in seasonal measures of wildfire size and frequency were observed. In the conterminous United States, western ecoregion provinces show north-south gradients in duration of season (short-to-long) and peak of season (early-to-late). Across the continent a gradient of unimodal to bimodal seasonal distributions of wildfire size and frequency was shown: western ecoregions have a single summer fire season and eastern regions have spring and late-summer fire seasons separated by an intervening dip in wildfire activity. From the ecoregion provinces with the highest wildfire frequency, average size, and area burned values, eight federal land units (four from the western and four from the eastern conterminous United States) were selected for a study of geographical variation in interactions between wildfire variables and the Keetch-Byram Drought Index (KBDI). Daily KBDI values for each location were provided by the North American Land Data Assimilation System (NLDAS). Confidence intervals around the mean for both days on which wildfires ignited and for days on which no new wildfires ignited were generated for each location using a bootstrap resampling method. A greater difference existed between nonire and fire-start KBDI values in the western locations, indicating a stronger association between KBDI and wildfire potential. At eastern locations, the difference between mean nonire and fire-start KBDI was lower than the minimum western mean difference for three of the four locations. The exception, the Great Dismal Swamp National Wildlife Refuge, showed the second highest difference between nonire and fire-start KBDI values of all eight federal land units. These results indicate that across the southeastern United States, the soil moisture (and, by extension, fuel moisture) cycle from field capacity (saturation) to drought (wilting point) and back to field capacity does not follow the regular seasonal pattern shown in the western states, and neither do geographical characteristics of wildfires.
