The Herbivory Variability Network has standardized protocols for surveying herbivore damage on plants around the world and across the tree of life. Members contributing data to the HV database need to use these standardized protocols to ensure their data conform to our methods. And we encourage all plant-herbivore researchers to use the protocols as well to help make data comparable across studies.
Please see the Protocols Overview chapter of the HV Manual for an overview of all of our protocols and when they should be used.
Before you start collecting data, we strongly recommend you review the manual to develop an understanding of the motivations and structure of the project. For example, an overview of the project can be found in Chapter 1, and our network structure is described in Chapter 2.
For convenience, here is a list of links to all of our protocols:
