The Big Island Invasive Species Committee (BIISC) and Kohala Watershed Partnership (KWP) are offering training to interested volunteers in the Kohala area. Volunteers can learn how to join in the effort to preserve the integrity of their district’s landscapes, forests, farms, and watersheds.

According to forestry officials with the Alabama Forestry Commission, two beetles trapped in
The beetle carries a fungus that causes a destructive disease called “laurel wilt.” The fungus moves into the tree, and infects the sapwood. As this fungus spreads, it clogs the vascular system of the tree, causing it to wilt. The infected tree will exhibit wilting foliage that is reddish or purplish in color. Eventually, the entire crown wilts and reddens. In the latter part of the infestation, toothpick-like tubes appear on the trunk of the tree caused by fine sawdust and frass seeping through the entrance holes. If a cross-section of the main stem is viewed, it will show black discoloration of the sapwood. Approximately two weeks after the initial attack, the host tree dies from the disease.
Redbay (Persea borbonia) is the most susceptible tree, but sassafras, camphor and avocado are also known to succumb from laurel wilt disease. Other possible host trees in the
The public can help prevent the spread of the redbay ambrosia beetle and laurel wilt disease by following these simple suggestions:
- Become familiar with the signs of laurel wilt disease and redbay ambrosia beetle and be on the lookout for evidence of the pest or disease on your trees.
- Use local firewood only – Redbay firewood should not be transported. Do not transport firewood of any kind from other states because destructive pests and diseases, such as redbay ambrosia beetle and laurel wilt, can hitchhike into
on infested firewood. Alabama
- Do not transport host trees (redbay, swamp bay, avocado, sassafras, pond spice, pondberry, and others in the Lauraceae family) unless purchased from a registered nursery.
- Avoid spreading the beetle and pathogen to new areas - Wood or chips from infested trees should not be transported out of the local area where the trees were found. Dead redbay or other Lauraceous tree species cut in residential areas should be chipped and left onsite as mulch, or disposed of as locally as possible.

This is the kind of action which can help to bring everyone on board. We all need to take action and work together to protect the rivers, lakes and other natural areas we love or they will be gone, taken over by invasive species. To read more click here.

The Center for Invasive Species and Ecosystem Health taught an EDDMapS training workshop at Tift County High School last Tuesday. Fifteen AP Biology students participated in the workshop. Karan Rawlins, the Center's Invasive Species Coordinator, first showed the class a powerpoint on the most common invasive species in the area. Then, she took the class outside to find and map invasive species. Students found Chinese privet and honeysuckle all over the school campus. Lastly, Rawlins taught the students to upload the information into EDDMapS (www.eddmaps.org). The workshop was a great success and the students were surprised to learn of the many invasives in their "own backyard". To learn more about EDDMapS workshops contact Karan Rawlins at 229-386-3298 or firstname.lastname@example.org.
