UC Natural Reserve System

UC Davis researcher Richard Karban has worked on sagebrush communication at Sagehen since the early 2000’s. Among other startling revelations, his work suggests that plants have self-recognition, the first step required for several things we typically associate with higher animals; like immune systems and kin selection, for instance.

Rick and his team continue to publish ground-breaking research, and a recent University of Chicago Press book, Plant Sensing and Communication, that is hailed as the new standard in its field.

“Richard Karban gives an introduction to a secret world: the multiple ways via which plants obtain information on their environment. Plants identify microbes and animals with which they are in contact, distinguish friends from foes, perceive the presence and degree of attack of their plant neighbors. They successfully integrate all this information and respond with adequate behaviors to enhance their chances of survival and reproduction.” — Martin Heil, Cinvestav Unidad Irapuato, Mexico

Karban scored a coup that eluded us when he brought Michael Pollan to Sagehen to research an article that appeared in the New Yorker, Christmas 2013.

How To Do Ecology, Karban’s popular press book is now in its second edition.
