Conservation and Management: Invasive Plant Species

 

The Spring Island Trust needs your help!

Please help locate and kill invasive plants in your yard and beyond. An invasive species is one that is not native to this area. Invasive species out-compete native species.

Dedicated volunteers like the tallow tree task force have helped keep invaders in check. However, we need everyone's help. Listed below are some of the invaders on Spring Island right now. You do not need to ask permission to get rid of these in your yard or anywhere else.

How to kill them:

For plants up to a few inches in diameter, cut (or break) the stems with loppers, chainsaw, or axe. Next, spray the stem with a brush-killing herbicide such as Roundup (Glyphosate). Other good herbicides include the active ingredients Imazapyr or Triclopyr. (You'll have to read the side of the herbicide bottle). Generic versions can be bought at Lowes or Home Depot.

For small plants you can just spray the leaves directly during the growing season.

For tree-sized invaders, you can either cut it down or use the hack and squirt method. For the hack and squirt method, take an axe or hatchet and cut around the truk. Then spray the herbicide into the cuts.
