Helping the Forest Stay Healthy

Poverty Prairie is another special spot. It’s 120 acres big. Rare plants live there. Workers clear weeds to keep them safe. I worked on kelp forests in Australia. It’s similar work. Healthy places need help to stay strong. Since 2014, the District has cleared many bad plants. This helps animals and plants live better.
