Frost – an invasive species sniffing super doggo – is on a mission to keep @grandtetonnps invasive plant free! 🐾 Frost and his caretakers with the Working Dogs for Conservation and Teton County Weed and Pest are working with Grand Teton National Park to locate, remove and eradicate the salt cedar shrub, also known as “tamarisk,” and the shrubby, long-lived perennial pepperweed. These aggressive plants alter ecosystems, displace native plants and animals, threaten and endanger species, decrease plant diversity and reduce nesting frequency of waterfowl in wetlands. They’re just some of the heroes safeguarding our pristine habitats. On Halloween, let’s give a round of appaws to Frost and his squad for helping to keep our public lands and their ecosystems healthy! 👏 Photos by C.
