CAMP CADY WILDLIFE MANAGEMENT AREA RESTORATION PROJECT
The objective of this continuing demonstration study is to determine the potential suitability and sustainability of selected plant materials for site restoration/revegetation on riparian salt cedar infestation sites along the Mojave River, within the Camp Cady Wildlife Management Area’s jurisdiction.
The monitoring in November of 2018 showed an even greater mortality of the re-sprouts from spring of 2016, leading to honey mesquite and screwbean mesquite completely dying off with this survey, and the Fremont cottonwood and Cattle saltbush gone by earlier surveys. The November monitoring showed the fourwing saltbush in the sandy loam surpassing the desert willow for the entire 2018 year. The planting study sites include locations in a salt cedar understory and in an open wash. The higher survival ratings for this monitoring were seen in the sandy loam understory without exception. Some nearby tamarisk has grown large enough to possibly affect the micro-habitat of some of the plants, and some tamarisk are growing along the line, providing direct competition. Tamarisk treatment was postponed in the fall of 2017 and 2018 to allow the newly discovered tamarisk beetle a chance to proliferate. The environmentally stressful situations that have caused an increase in mortality have also been beneficial in the determination of what native species to use in the future for Mojave River riparian restoration.
The weather station was not operational for this monitoring due to a dead battery. The new battery has since been replaced and data has been retrieved from as far back as October 2018. The well pump and water lines are in the process of being renovated so the water line break in the summer of 2017 will not happen again. Plants that have perished are scheduled to be replaced and monitored in the future.
The next planned data collection will be spring of 2019, at which time survival and plant vigor measurements (e.g., canopy height, canopy diameter, evidence of floral reproduction, etc.) will be taken.
