Presentation on control methods for the invasive bush honeysuckle.

1. Efficient Control of Bush Honeysuckle,
Lonicera mackii.

2. Biology and Life History
• Range: Endemic to
northeastern China,
Manchuria, Korea,
and Japan.
• Introduced in
Europe in 1887,
Canada in 1896,
and US in 1898 at
the New York
Botanic Garden

3. Current Range in North America

4. Criteria used in determining the priorities in
honeysuckle control
1. Is it a high quality habitat?
There are mature trees, diverse native plants or rare
species present.
2 Is it accessible for efficient control?
More acres can be restored.
3. Is there direct public benefit?
Includes overlooks, trails, recreation areas.
4. Is it a seed source?
Honeysuckle exposed to sun light on edges or in full sun produce seed.
5. Is the area impacted by E.A.B. or deer?
Invasive plants have more impact here.

5. Over browsing by deer

14. Before control

15. After control

16. Open Soil invites invasives
Seed it or weep.

17. Fill the void!!!!!
Grassy Matrix of Virginia Wild Rye and River Oats
allow For selective control year 1 and 2

18. Maintenance is key, Burn, Mow or Spot
Spray Yearly or as needed.

19. Prairie planted after honeysuckle was removed.

20. Add desirable species 3 to 4 years later
