Asian Honeysuckle and Multi-Flora Rose
Invasive species are introduced to an area in many different ways, either on purpose or by accident. Birdsfoot trefoil, for example, is planted as cattle forage. Asian honeysuckle has been used in landscaping and is spread by birds. Other non-indigenous plants move to different places clinging to tires, shoes, or animals.

Brush clearing usually takes place in the late fall, winter, and spring:
- Felling trees with chainsaws by trained sawyers
- Loppering branches and shrubs
- Girdling trees to cut off their water supply
- Applying herbicide as needed
- Dragging limbs and vines to brush piles
- Burning brush piles when conditions permit
|
|
Weeding is most intense from May to August:
- Pulling, digging, clipping, or herbiciding plants, depending on the species
- Carefully applying small amounts of herbicide when necessary to prevent reprouts
- Hauling refuse away from the area if reseeding could occur

Safety and effective management practices are always considered when clearing brush or weeding. Several protocols established to protect our workers and eco-system are followed by all staff members, stewards, and other volunteers.
