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.  During the summer and fall of 2018 there were much needed upgrades to the old piping system at Camp Cady.


The Camp Cady restoration plant sites were monitored in December of 2019.  At this time the highest average survival rate across both planting sites was the desert willow.  While the fourwing saltbush showed over 80% survival rate in the sandy loam in the Spring of 2019, it had fallen to only 56% by the fall of 2019.  While the desert broom showed higher survival rates in some soil types it was lower in other sites from the last report.  The waterjacket did not have a survival rating at all and none were found alive by the fall of 2019.  Overall, the Desert willow, Desertbroom, and the Gooding’s and Narrowleaf willows made the most come back and survivability by the fall of 2019.  Other native plants have established in the study area showing what species will survive in the salty and sandy environment. Some nearby tamarisk have grown large enough to possibly affect the micro-habitat of the plants.  The water uptake from the saltcedar may affect the nearby plants water availability.  Also, the partial shading from the remaining controlled saltcedar debris may affect the plant survival for these species in the sandy loam understory.  The chemical treatment of the tamarisk has not been completed because of the recent presence of the tamarisk beetle.


The weather data during the 12 months before the fall observation showed similar conditions in soil and air temperature, though precipitation varied widely.  All data was obtained from the HOBO data stationed at the Camp Cady site.  CIMIS weather station 234 in Newberry Springs data was supplemented for any missing data from the HOBO station.
