摘要：While urban trees increase property values and improve human health, healthy urban trees also reduce potential infestation of nearby native forests. We developed a collaborative program to raise public consciousness of risks to trees from invasive insects before injury has occurred. The Nevada Department of Agriculture entomologist trained Extension Master Gardeners to recognize the threats, signs, and symptoms of alien arthropod species. They then taught classes in venues around the state, bringing awareness of potential problems. By 2013, over 700 professionals and local residents had attended a class, increasing the number of educated and concerned observers around Nevada.
