Landscape of a partially burned forest

Many different species of sap suckers currently threaten California forests. Some native, some not, sap suckers feed primarily on the sap of trees and shrubs on a seasonal basis. Because sap suckers intensely attack trees, they can cause serious health issues and death to plant species, with some varieties impacted more than others.
