Welcome to the Herbivory Variability Network (“HerbVar”). We are a global research network that aims to describe and understand how and why patterns in plant–herbivore interactions vary across the tree of life and around the world.

Although we are a new network (founded in mid 2019), we already have more than 200 collaborators from more than 100 institutions across 30+ countries. Please email Will Wetzel, Moria Robinson, or a member of the HerbVar Planning Group if you are interested in joining us. We are always looking for additional collaborators, especially those who can contribute data from under-sampled regions or from new plant families or focal plant families and species.

Our growing dataset currently has >400 surveys of >300 plant species from >110 plant families. These are spread across North America, Central America, South America, Europe, Africa, Asia, and Australia, and we are working to expand our geographic extent.

Sampling areas with at least one completed survey. We’re continually adding new sites.

The Herbivory Variability Network is run out of Michigan State University. Support and seed funding for coordination was provided by MSU AgBioResearch, MSU Department of Entomology, and MSU CANR International Programs.
