Ka‘ala Weed Control (firespike)

TARGET WEED: firespike (Odontonema cuspidatum)

PROJECT: We will control invasive firespike (Odontonema cuspidatum).  We will use small hand tools such as saws, pruners and loppers to control the fire spike.  The work area will also contain Florida blackberry (Rubus argutus), therefore long sleeves and long pants are required in order to avoid getting scratched by the blackberry thorns.

HIKING TIME: 30 minutes (round trip)

DIFFICULTY: Difficult; volunteer project will occur on a steep, uneven slope

WHAT TO BRING: Long pants, long sleeve shirt and shoes with good traction (you are welcome to borrow spiked tabis from us). Please review the suggested packing list.

All weeding tools and gloves will be provided.
