Celebrate Earth Day with Carmel Clay Parks & Recreation. Help with habitat restoration at the Woodland Gardens in Central Park. We need your help for invasive plant removal in these woodlands. This is part of a multi-year effort to remove Garlic Mustard from this area of the park and you can be a part of this year's volunteer force. Garlic Mustard is easily hand pulled and can be completed by volunteers of all ages. Volunteers 16 years and under will require the supervision of a parent or guardian.
