83 <br />• <br />upper profile. Panels 3 and 5 had surface soil moisture readings <br />intermediate between the high of Panel 6 and the low of Pane1.4 <br />Soil temperature-moisture cells were installed on each sub-subplot <br />in the northern and southern replicate of each panel. They were buried <br />at a depth of 15 and 45 cm and will be monitored during the upcoming <br />field season. <br />Plywood paneling was installed on the northern and southern ends of <br />each panel during the 1978 field season. With this installation, each <br />panel is now completely encompassed by plywood paneling to the lower <br />depth of the profile configuration. This was done to insure that root <br />growth is confined to the artificial soil-shale profile and does not grow <br />into adjacent buffer areas. <br />A rodent-proof fence was constructed around the Retorted Shale <br />r~ <br />U <br />small herbivores and enable us to adequately assess plant response to the <br />Successional Study this past year. It will minimize plant damage from <br />various treatments. <br />Besul.ts <br />The data obtained during the first sampling year was reduced and <br />then analyzed statistically. An analysis of variance was run on all <br />subplot treatment means for biomass, cover, and density by life form. <br />Tukey's Q-tests were then utilized to determine significant differences <br />between treatment means. <br />All the results presented in the following section are based on data <br />l__J <br />collected during the August 1978 sampling. The response from the shale- <br />to-surface treatment (Panel 1) is nearly always significantly different <br />from the response on the other five panels. This is because a stand of <br />
