Spring 2021 Southern Run

Volume 5, Issue 4

CEC Research Spring 2021 southern run cover — Glandular manzanita (Arctostaphylos glandulosa) produces sticky hairs all over their new growth. These hairs deter herbivores, but can also trap tiny insects that aren’t eating the plant. The dead insects may attract predatory invertebrates that, in turn, can protect glandular manzanita from being eaten. The causes and consequences of manzanita stickiness was one of seven research projects conducted at James San Jacinto Mountains Reserve by students in the southern run of the Spring 2021 California Ecology and Conservation program.
