WHAT’S NEW AT USA-NPN
July 14th, 2021
Each summer, we deliver a Buffelgrass Pheno Forecast to aid managers in knowing where and when invasive buffelgrass is green across Southern Arizona. The forecast is based on known precipitation thresholds for triggering green-up to a level where management actions are most effective. In 2021, we added weather station-based forecasts of buffelgrass green up to the gridded forecasts to provide managers with additional data about rainfall. This additional information is available in the Visualization Tool. We also have 12 other Pheno Forecasts on a variety of insect pests.
