What causes this damage to coconut trees? This question is one for Hawai‘i island residents: people on Guam, American Samoa, and sadly now on O‘ahu are only too familiar with the damage caused by the coconut rhinoceros beetle (Oryctes rhinoceros). V-shaped cuts in the leaves (photo 1) and large holes bored in the stem just below the crown (photo 2) are signs of the beetle. CRB has been found on the Kona side of Hawai‘i island but so far is still isolated there and could still be eliminated. If you are on the Big Island and you see signs of coconut rhinoceros beetle, please report it to the Big Island Invasive Species Committee: https://www.biisc.org/pest/coconut-rhinoceros-beetle/ That website also has great information about the current status of the beetle, signs, look-alike species, and more.

A good story about our forest landowners program.

Over 100,000 acres of forest on Hawaii Island are located on private land. Since 2012, a program through the University of Hawaii’ has been working to educate and equip the owners of this land with the tools and knowledge necessary to sustainably care for these forests.

Great to see a Hawaiian tree in Waikiki, even though it is a canoe plant and botanically not native. Hope everyone enjoyed the Hawai’i Conservation Conference.
