Major Project Activities
Long-term ecological research on prairie ecosystems in Nebraska is the major emphasis of the grassland ecology research project. Responses of the vegetation to continuing changes in the environment are collected annually from plots delineated in the Sandhills in 1926. The recent dry cycle followed by average precipitation resulted in numerous shifts in abundance of plant species.
Work continues on a cooperative project initiated in 1981 with Dr. Thomas Bragg, University of Nebraska-Omaha, to determine the influences of frequency and season and frequency of prescribed burning and mowing on restored tallgrass prairie vegetation. Patterns of succession in Sandhills blowouts are being mapped in another long-term study. The objective of this study is to model plant community succession and dynamics of Sandhill blowouts. Using remote sensing tools, we are delineating blowout occurrence and change, especially with respect to topography and climate patterns.
Work continues on the ecology, propagation, and recovery of blowout penstemon (Penstemon haydenii S. Wats.). This spectacular Sandhills wildflower is the only Nebraska plant on the Federal Endangered Species List. Research and recovery associated with this project have increased plant numbers to a level that qualifies it for reclassification to Threatened. The US Fish and Wildlife Service is using data generated by this project in a review of the status of the classification. Recent work has concentrated on analyzing the influences of wind and sandblasting on seedling growth and how seeding depth affects germination and emergence. These data will help to quantify the seed bank and potential expansion of this species.
In another phase of the seed bank studies, an undergraduate student working on a UCARE project is determining the viability of blowout penstemon seeds collected over the past 28 years and stored under different conditions. Correlations between climatic variations and abundance of blowout penstemon for the last 23 years are being examined. Research to determine seed production of wetland plants in relation to grazing is being conducted in wetlands in the Rainwater Basin of Nebraska.
This work is a continuation of a project that explored innovative ways to restore wetlands with grazing. Dr. Heidi Hillhouse (Post-Doctoral Research Associate) and Cheryl Dunn (Grassland Ecology Research Technologist) are staff associated with the project. Graduate students include Barbara Kagima (Ph.D.), Luis Ramirez (Ph.D.), Michelle Koch (M.S.), Cortney Schuler (M.S.), and Sal Palazzolo (M.S.). Sammi Bray is an undergraduate student working on a UCARE project.
