You can help the fight against invasive species by tracking phenophases of invasives through the USA National Phenology Network’s Nature’s Notebook. We need observers to track species such as leafy spurge, purple loosestrife, and tamarisk-species designated as invasive by the USFS, USGS and NatureServe.
Invasive species have infested hundreds of millions of acres across the United States, causing widespread disruption to ecosystems and reducing biodiversity. The invasive species threat is one of the top priorities of the US Forest Service. Knowledge of invasive species phenology can assist managers to better control invasives and predict future spread. The purpose of the Track Invasive Species project is to monitor distribution and phenophases, or life cycle events, of invasive species across the US.
