The primary objective of my research program is to determine the limiting factors controlling rangeland-seeding success and to utilize this knowledge in the development of methodologies and technologies that result in the establishment of functional native plant communities.  Linked objectives include: 1) quantifying the role and impact of edaphic, climatic and biotic factors on plant survival and plant productivity; 2) determining how barriers to restoration success vary across the landscape; and 3) developing and or identifying seed enhancement technologies (e.g., seed coating, pelleting, deterrents, biological and physiological treatments, and other non-traditional methods) that are capable of mitigating ecological processes and conditions limiting plant establishment.  In addition to rangeland systems, I am also seeking to develop and apply innovative seed enhancement technologies for use in other ecosystem types and in various agricultural sectors.
