Dissertation/Thesis Abstract

Riparian forest dynamics along the Sacramento River, California: Constructing tree age models to illustrate successional patterns
by Irons, Andrea M., M.S., State University of New York College of Environmental Science and Forestry, 2016, 137; 10245526
Abstract (Summary)

Though land conversion and flow alteration have heavily impacted the Sacramento River riparian ecosystem, restoration opportunities still exist in the hydrogeomorphically active Middle Reach. This study of riparian forest succession focused on six dominant riparian tree species to explore relative establishment timing and the potential impacts of altered flow regimes. We utilized tree inventory data and increment cores collected from riparian forest stands to establish a temporal chronosequence of floodplain surfaces and associated tree ages and colonization timing. Tree age calculations incorporated raw ring counts and sampling error simulations. Results were then used to construct species-specific, diameterage models and predict age distributions for all inventoried trees. Cottonwood’s colonization window was longer than expected (up to 95 years after floodplain creation), whereas box elder and walnuts established on floodplains <50 years old. This study lays the groundwork for future research into the health and development of the Middle Reach riparian forest.
