Title: A Pilot Investigation of Cottonwood Recruitment On The Sacramento River |
|
|
Abstract/Description: We collected dendrochronological data, hydrologic data, and topographic survey data at one pilot study site
on the Sacramento to calibrate an ecological model for cottonwood recruitment developed on other rivers.
We also conducted a field reconnaissance of recent cottonwood recruitment and reviewed an analysis of
historic stream gage data to investigate the degree and potential nature of limitations to recruitment on the
Sacramento River. Data from this pilot study suggests that the recruitment box on the Sacramento River
may need to be altered compared to other rivers. Specifically, cottonwoods may recruit at higher elevations
on the Sacramento when compared to other rivers of smaller magnitude. In addition, field reconnaissance
suggests that recruitment is limited on the Sacramento River. We found only 20 acres of stands over 37
river miles, which appeared younger than the youngest trees aged at the pilot site. IHA modeling revealed
current flow characteristics in direct conflict with relationships specified in an ecological model to facilitate
recruitment. Data from this study was used to formulate flow recommendations, which facilitate
recruitment of riparian forest.
