Patch Seeding On An Extensive Green Roof: Initial Experiment On Microclimate Impacts, Zhuqing Xu
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
The green roof provides not only aesthetic values but also many ecological benefits. In North America, seeding or reseeding with native species becomes increasingly popular as a result of its high efficacy and low cost. The extreme temperature and a lack of water on the green roof impose restrictions on seeds germination that determines the success of a seeding program.
The study started on June 1 and was completed by July 15. Five Great Plains native species were hand-seeded in two blocks on Larson Building green roof, along with two blocks set up in the greenhouse at University of Nebraska-Lincoln …

Ecology And Invasive Properties Of Musk Thistle (Carduus Nutans) In The Central Prairies Of Nebraska, Chengchou Han
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Musk thistle (Carduus nutans) is an herbaceous monocarpic herb introduced to the U. S. from Eurasia. The invasion of musk thistle can reduce forage area, soil stability, and reduce recreation and open areas for humans and wildlife.
Resistance of warm season and cool season perennial grass communities to musk thistle invasion is important for land managers to consider, especially where disturbance has made an area particularly susceptible. Our results show that disturbances, such as overgrazing can open up niches in canopies of warm season grass communities and facilitate invasion but not in cool season grass communities. The mechanism …
