The FHTET Spatial Statistics provides spatial statistic methodologies to model potential tree pest problems, such as oak wilt and mountain pine beetle. Our spatial statistic models can help natural resource managers, city planners, landowners, developers and others target resources, conserve forests, make informed decisions, operate more efficiently, and prioritize suppression and control activities more effectively.
