At the same time resources are becoming more scarce there is an increase in the use of parks, wilderness and other natural environments for recreational purposes. This is evident in British Columbia where much of provincial parks planning is concerned with the accommodation of an ever increasing diversity of outdoor recreation activities. For a variety of reasons the people engaged in those activities do not always get along therefore resolving these social conflicts is becoming an ever larger part of recreation resource planners’ and managers’ jobs. The problem with conflict management in outdoor recreation is that the methods which are commonly used do not address the sources of conflict. Even though it is the recreationists who are experiencing conflict the focus remains on managing the resource. The traditional conflict management prescription is to separate activities that are considered to be incompatible. This action is necessary in some cases but it can often exacerbate the conflict. Since the reasons for conflict are largely sociological and psychological it is necessary that the groups in conflict get together to find a solution. Conflict management methods based on the spatial separation of activities that do not include this step will not be as effective as those that do. This thesis establishes a number of weaknesses in activity based conflict prevention by examining both the sources of conflict in outdoor recreation and the methods of conflict management which are traditionally used. These weaknesses are then considered in a two part examination. First, the conflict management policies of BC Parks are examined. Second, a closer look is taken at a specific conflict issue: the Garibaldi Master Plan and its treatment of the issue of mountain biking in the park. In general, without a formal conflict management policy in place users of BC’S provincial parks who find themselves in conflict with other users can not be assured that the sources of conflict will be addressed. In the Garibaldi Park case study, BC Parks focused on managing the resource rather than managing the social conflict that was occurring. They took steps in the right direction but failed to take the most crucial step which is getting the parties in conflict talking to each other. Even though the sources of conflict are recognized they are not the prime consideration in resolving the conflict.

In Canada, the endangered prairie skink (Plestiodon septentrionalis) exists only in southwestern Manitoba. Habitat loss is the most significant threat faced by the prairie skink in Canada, with leafy spurge (Euphorbia esula) invasion identified as one of the suspected factors contributing to habitat loss. The objectives of this study were to determine microhabitat preferences and effect of leafy spurge on prairie skinks in southwestern Manitoba. To determine microhabitat preferences, occupied sites were compared to unoccupied sites. Artificial cover was identified as the most important microhabitat element. To determine the impacts of spurge on microhabitat, ground temperatures in invaded were compared to un-invaded sites. No significant differences in temperature or skink density were observed between invaded and un-invaded site; however, skinks were more likely to use spurge when cover was present, than when no cover was present. Artificial cover may improve microhabitat by providing refuge from predators and microhabitat for prey.

Archival records are essential for understanding changes in the environment. However, these records are largely ignored by archivists, who overwhelmingly focus on records of human history. Algonquin Provincial Park in east-central Ontario was established in 1893 and is the oldest park in the Ontario Ministry of Natural Resources, Provincial Parks system. In addition to the many official functions and activities that occur in Algonquin Provincial Park, it is host to extensive environmental monitoring, assessment and research. However, no adequate system is in place to ensure that the records of archival value are identified, appraised, and preserved. An appraisal methodology is required to assist archivists to identify environmental records of long-term value. Using Algonquin Provincial Park as a case study, through primary source analysis of its structures and functions and comparisons with other park systems, various archival appraisal theories and methodologies are tested in order to determine the best method for appraising environmental records in general and the records of parks. It is determined that macroappraisal is the best method for appraising only the records created by the official functions and activities of Algonquin Provincial Park. However, the park depends on and interacts with many external affiliated organizations, including the Algonquin Forestry Authority, The Friends of Algonquin Park, Algonquins of Golden Lake First Nation, leaseholders, researchers, protest groups, anglers, businesses and contractors. The creation of environmental monitoring, assessment and research records is increasingly accomplished external to official government functions and activities. Many of these external groups create environmental records of archival value, yet, no formal strategy to preserve irreplaceable records is implemented in Algonquin Park. Elements from archival appraisal methodologies such as macroappraisal, the documentation strategy and the Minnesota Method are helpful for determining the relative archival value, and therefore level of documentation, of these external individuals, groups and organizations. This combination of methodologies is the most effective for ensuring the preservation of important environmental information and subsequently the environment. Various preservation partnership strategies are also suggested for these records identified as having archival value.

Basaltic volcanism in the form of small-volume, subaerial and subaqueous eruptions have occurred in the Wells Cray—Clearwater area of east central British Columbia. These eruptions have been dated by the K-Ar method and by relationships to dated glaciations. The oldest known eruption may be as old as 3.2 Ma, but is more likely 2 Ma or less. The youngest eruptions are less than 7560 ± 110 radiocarbon years. The most extensive basalts are valley-filling and plateau-capping flows of the Clearwater unit, which are Pleistocene in age and greater than 25 km³ in volume. The deposition of flows of the Clearwater unit has overlapped at least three periods of glaciation. The interaction of glacial ice and basaltic magma has been recorded in the form of tuyas, ice ponded valley deposits and subglacial mounds (SUGM). In a few place glacial till has been preserved beneath basalt flows. Flows of Wells Gray—Clearwater suite appear to have erupted from vents that are both spatially and temporally separated. The individual eruptions were of low volume (<1km³) and chemically distinct from one another. Major element composition is variable but the lavas are predominantly alkalic. Olivine is the predominant phenocryst phase. Plagioclase and augitic clinopyroxene rarely occur as phenocrysts, but both minerals are ubiquitous in the groundmass. Orthopyroxene was not seen in any of the samples. Flows appear to have erupted with minimal crystal fractionation or crustal contamination. The range of compositions seen in the suite is best explained by a process of partial melting and the progressive depletion of the mantle source by earlier melts. Progressive depletion of the mantle source was coupled with enrichment of parts of the mantle in K as well as some lithophile and siderophile elements. Increasing alkali content may have triggered the highly enriched eruptions of Holocene age that, despite very low degrees of partial melting, were capable of reaching the surface. Overprinting the effects of partial melting are inherited heterogeneities in the source zone of the magmas. Based on whole-rock chemistry the magma source appears to be a highly depleted region similar to that which produces the most depleted mid-ocean ridge basalts (MORB). The zone is, however, capable of producing large volume (≃ 15%) partial melts and has not been isotopically depleted to the same extent as MORB source regions. Isotope analyses of ⁸⁷Sr/⁸⁶Sr, ¹⁴³Nd/¹⁴⁴Nd and whole-rock Pb indicate that the magmas may be derived from a remnant of subducted oceanic lithosphere which has been variously depleted by the prior generation of basaltic melts. Isotopic enrichment above the level seen in MORB's is due in part to crustal contamination. The isotopic results are very different than those obtained from samples erupted through thin, allochthonous crust in the Intermontane Belt and may be explained in part by generation of the magmas in oceanic material which was subducted when allochthonous crust lay against the parautochthonous rocks underlying the Wells Cray—Clearwater area. The alkali olivine basalts of the Wells Cray—Clearwater area have erupted onto a tectonically active surface. A peneplain (erosion surface), formed in Eocene-Miocene time has been uplifted since the Miocene and uplift may be continuing. This uplift is in response to an elevated geothermal gradient which may be due to crustal extension. This crustal extension may be similar to that which occurred in the Eocene. The elevated geothermal gradient and reduced pressures attendant with recent uplift and erosion may have initiated basaltic volcanism in the region, rather than a fixed mantle hot spot as proposed in earlier work. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate
