• Monitor Whitebark/Limber Pine

• Monitor Post-Exotic Plant Control/Effect On Natural Communities

• Monitor revegetation success

• Document and Evaluate Effects of Road Reconstruction on Changes in Hydrology and Therefore Wetlands

• Resample Fire Monitoring Plots

• Evaluate/Correlate Historic Non-Forest Vegetation Trend And Condition Data Using Current Sampling Methods


RESEARCH

• Physical/Vegetation Relationships

• Restoration of the Xeric Sagebrush Steppe vegetation of “Triangle” and Boundary lands area

• Fire Ecology

• Sources of Weeds

• Plant genetics

• Vegetation/Wildlife Interactions—Implement Recommendations from the National Science foundation: (Portions of these are currently funded)

• Assess ecosystem stability, resistance, and resilience.
• Response of plant and animal populations/communities to changes in herbivore density
• Concurrent studies of riparian and aspen recruitment, weather/snowpack, etc.
• Have ungulates achieved a dynamic equilibrium with range conditions?
• Long-term investigations/experiments to evaluate management options.
• GYE-wide assessment of the conditions and factors that influence aspen stand structure.
• The relationship of herbivory and groundwater availability on riparian system performance.
• Ungulate herbivory of willows in relation to animal body condition and plant secondary compound production.

• Evaluate Whitebark Pine.Lodgepole Pine Interaction

• Continue/Expand Study of Aspen Biogeochemistry

• Continue/Expand Study of Secondary Metabolites


MANAGEMENT

• Expand Ongoing projects:

Inventory Resources for Compliance

• Document Vegetation impacts from social trails

• Restore Disturbed Lands

• Prepare Improved Vegetation Map

• Fire Management

• Document the Outwardly Creeping Edge of Developed Areas

• Compile History of Vegetation Manipulation in the Park
