Under real-world conditions a comparable situation might only occur when large amounts of fresh infected plant material is shipped to the composting facility in cool, rainy conditions, or if compost rows were to be under or near highly infected infectious hosts such as Rhododendron spp., California bay laurels or tanoaks.
Gray squirrels at these parks ate acorns, female and male cones (Pinus spp.), black berries from an unknown ornamental tree, and fruit from the California Bay Laurel (Umbellularia californica).
Habitat improvements such as planting trees like the California Bay Laurel and conifers and shrubs like Fremontodrendon may sustain the isolated populations of gray squirrels for a longer period of time.
This trial was performed to test the effect of a 2-layered medium structure and increased quantities of starch and yeast, as well as the effect of wood from 2 other species in the family Lauraceae, i.e., California bay laurel (Umbellularia californica (Hook.
Females on media A, C and E had higher probabilities of successfully producing brood than those on the medium prepared using California bay laurel wood but not the other media tested (Fig.
Another member of the Lauraceae of much concern is the California bay laurel [Umbellularia californica (Hook.
In the third experiment, bolts of redbay, avocado and California bay laurel were hung at Ordway-Swisher Biological Station, University of Florida, Gainesville (N 29[degrees] 41.040, W 082[degrees] 22.109).
The aggregation site was oriented in a northeastern direction and fully shaded from direct sunlight by the bedrock ledge and by a mature riparian canopy of interior live oaks (Quercus wislizeni), California bay laurels (Umbellularia californica), and big-leaf maples (Acer macrophyllum).
