Plant Demographic Studies Of A Desert Annuals Community In Northern Utah Dominated By Nonnative Weedy Species, David R. Duba
Plant Demographic Studies Of A Desert Annuals Community In Northern Utah Dominated By Nonnative Weedy Species, David R. Duba
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Field and laboratory investigations were conducted relating to factors controlling distribution and abundance of annual species growing in a disturbed portion of the salt desert shrub zone on fine-textured soils. Dominant species on the site in the two study years were the nonnative, Halophytic, late-summer maturing, Halogeton glomeratus (Bieb.) C.A. Mey., and Bassia hyssopifolia (Pall.) Kuntze. Contrasting amounts of precipitation were received in the two years; in 1974, spring conditions were so dry that two early-maturing, sub-dominant annuals, Descurainia pinnata (walt.) Britton, and Lepidium perfoliatum L. were essentially absent. They successfully reproduced under more favorable 1975 conditions.

The Effect Of Protective Materials On The Overwintering Of Hardy Annuals, Candytuft And Stocks, Melvin S. Burningham

Many hardy annual flowers will live through the winter if there is sufficient snow protection. Since snow cover is not consistent from year to year it has been suggested that hardy annuals planted in late summer and provided with some kind of protection before severe freezing begins will live through the winter successfully. Not only would this enable plants to bloom four to six weeks earlier, but would also enable gardeners to utilize flowers not commonly grown in northern Utah.
Some studies conducted at the Utah Experiment Station in Farmington have indicated that plants such as candytuft and snapdragons can …
