Hawaii hopes to fend off invasion by coconut rhinoceros beetle

Visitors flock to the Hawaiian Islands for sun-soaked holidays filled with silky beaches, turquoise water, lush green hillsides — and naked palm trees missing their leafy crowns?

That possibility has state officials worried because Hawaii’s iconic swaying palm trees are under attack. Their nemesis is the latest in a long line of invasive species to arrive here: the coconut rhinoceros beetle.

Much as the Asian long-horned beetle attacked maple and elm trees on the East Coast, the coconut rhinoceros beetle could devastate Hawaii’s palm trees and move on to bananas, papayas, sugar cane and other crops afterward. Adult beetles burrow into the crowns of palm trees to feed on their sap, damaging developing leaves and eventually killing the trees.

At this point, eradication is still possible. It’s going to take a long time, but it’s still possible.- Rob Curtiss, incident commander for Hawaii’s coconut rhinoceros beetle eradication program

Concerns that the thumb-sized pest, named for its curved horn, could hitch a ride to California or Florida and attack thriving palm oil and date industries there have prompted federal and state officials to declare the beetle’s discovery in Honolulu a pest emergency.

One year into the fight — Dec. 23, 2014, was the anniversary of the beetle’s discovery on coconut palms at Joint Base Pearl Harbor-Hickam — state officials are cautiously optimistic.

“At this point, eradication is still possible. It’s going to take a long time, but it’s still possible,”

Ant infestation covers 4 acres in Waimanalo

HONOLULU — An extensive survey of an area in Waimanalo has determined approximately 4 acres are infested with little fire ants, tiny invasive ants that can inflict painful stings. Crews surveyed more than 50 acres from Kumuhau Street to Mahailua Street in Waimanalo and determined that the infestation area is on state land and in mulch areas located outside nurseries in that area. Little fire ants were detected previously on hapuu from Hawaii Island at a few nurseries and garden shops earlier this year, but those areas were treated and are now clear of little fire ants.

Survey operations were headed by the Hawaii Department of Agriculture and involved several agencies including: the Department of Land and Natural Resources, Hawaii Ant Laboratory, Oahu Invasive Species Committee, U.S. Fish & Wildlife Service, Coordinating Group on Alien Pest Species, Hawaii Invasive Species Council, The Nature Conservancy, University of Hawaii, City & County of Honolulu, and Hawaii National Guard.

Little fire ants have been found on Hawaii Island since 1999. In late December, the ant was detected on hapuu logs (Hawaiian fern) at retail stores on Maui and Oahu. Since its detection, Oahu and Maui nurseries have been surveyed. Five Oahu nurseries, three of which were in Waimanalo, were found to have small infestations of little fire ants, which were treated and are clear of the ants.

Invasive species bill has good intention, serious consequences

A Maui coffee farmer said controlling invasive species such as the notorious coqui frog and fire ant is a Big Island problem.

“They already have them, we don’t. Why put the cost on us?” asked Bobbie Becker, owner of Maui Mountain Coffee Farm. “They’ve got it there.”

Becker is a supporter of state Senate Bill 2347, which soon will be taken up by the House Finance Committee.

The legislation, written as an attempt to control the interisland spread of invasive species to the local agriculture industry, was amended last Friday. Parts of the bill would prohibit the transportation of the pests and establishes penalties for violations, including language that would require any commercial entity that transports the invasive species to pay a fine equal to the value of the infested shipment.

Eric Tanouye, president of Hawaii Floriculture and Nursery Association and vice president of Green Point Nurseries, called the bill “a detriment to the Big Island.”

“They are distracting, and distracting all of us from the main objective,” he said. “How do we make ag thrive on the Big Island and in the State of Hawaii?”

Springer Kaye, manager of the Big Island Invasive Species Committee, said the committee agrees with the intent of the bill, but does not support SB 2347 and thinks it puts the Big Island at a disadvantage.

Measure in state Legislature targets alien little fire ants

A bill in the state House would provide $500,000 toward destroying little fire ants.

Of all the ants in all the world, Hawaii had to get bitten by this one.

Hawaii lawmakers on Monday advanced a bill aiming to study and kill the little fire ant, a hard-stinging pipsqueak that threatens the state’s economy and ecology.

House Bill 2469 would provide more than $500,000 toward coordinating efforts to corral and destroy the little fire ant. It includes money to pay for trained dogs to sniff out the tiny pests and for public outreach.

At 1/16th of an inch long, the copper-colored ant does not cut a formidable figure. But since it first landed on Hawaii island 15 years ago, possibly as a stowaway on a potted plant from Florida, the ant has spread on the Big Island and has popped up on Maui, Oahu and Kauai.

Of the perhaps 30,000 species of ants on Earth, only six are considered “really nasty,” said Cas Vanderwoude, the research manager of the Hawaii Ant Lab at the University of Hawaii. Of those six, he said, the little fire ant poses the greatest potential threat to Hawaii.

“Our lifestyle and climate just suit this animal down to a T,” he said. “If I was a little fire ant and wanted to go on vacation, I’d come to Hawaii.”

The ants have proved onerous for several reasons, Vanderwoude said. They live in trees, where they infest crops and bite agricultural workers. They also live on the ground, where they attack people and pets, perhaps partially blinding cats and dogs by stinging their eyes. A single square foot of infested ground can contain 2,000 ants.

The ants travel between islands by hitching rides on crops and propagated plants. That threatens to undermine agricultural exchange among the islands and beyond. The ants also drive away insects, birds, lizards and mammals that prey on other pest insects, further harming crops.

USDA approves fireweed control

By HUNTER BISHOP

Tribune-Herald staff writer

hbishop@hawaiitribune-herald.com

U.S. Sen. Daniel Inouye announced Wednesday that the U.S. Department of Agriculture has approved a biocontrol project aimed at slowing the spread of fireweed, or Madagascar ragwort, on the islands of Hawaii and Maui.

Fireweed is a noxious, invasive species that has infected an estimated 850,000 acres on the two islands, more than 20 percent of the state’s agricultural pasture lands.

The weed has no natural predators in Hawaii and is resistant to drought which allows it to spread rapidly, and it is expected to spread to an additional 1.5 million acres in the next 10 years if left unchecked.

Agriculture officials plan to release a species of moth next month on the two islands. The moths, which, like fireweed, are native to Madagascar, have been studied under quarantine in Hawaii since 1999. They are known to feed on fireweed, which is toxic to livestock.

Tim Richards, president of Kahua Ranch and past president of the Hawaii Cattleman’s Council, said the news of the approval is huge for Hawaii, “and that’s an understatement.”

For the past 10 years, the cattle ranchers have been losing the battle against fireweed, using chemicals and mechanical means in an attempt to control it. But due to the immense size of the infestation, “those methods are not feasible or economical,” Inouye said.

“It’s an ongoing ecological wreck,” Richards said, spreading up from the coast into the rain forests. “Because of the drought it grows quickly.”

Axis deer hunter feels unfairly targeted

Axis deer hunter feels unfairly targeted

By TOM CALLIS

tcallis@hawaiitribune-herald.com

Shortly before Christmas 2009, a helicopter carrying four axis deer — three alive, one dead — landed on a Ka‘u ranch.

Its cargo, brought in a metal crate from Maui, was unloaded and replaced with several mouflon sheep for the return trip.

With the duct tape around their legs removed, the surviving ungulates needed little coaching to exit.

Sensing freedom after the interisland flight, they bounded toward the safety and familiarity of the nearby brush.

For the men involved, that moment marked the start of a new food source for hunters on the Big Island, long frustrated by state efforts to slaughter animals considered harmful to native plants.

But for state and federal officials who would discover their presence in 2011, the prospect of an invasive species here proved concerning.

The south Asian deer, already well-established on Maui, Oahu, Lanai and Molokai after being first introduced in 1868, have frustrated ranchers and farmers for generations but have been prized by hunters.

A U.S. Fish and Wildlife investigation would later trace their Big Island introduction to a hunter from Mountain View, and a rancher and a pilot from Maui who arranged a sheep-for-deer swap between the two islands.

Eager to punish the act, yet unable to declare the deer introduction itself illegal, federal prosecutors successfully convicted the trio last month for possessing game animals without a permit and under the Lacey Act, which governs interstate commerce.

Each was fined and sentenced to community service helping battle invasive species or educate hunters.

Monsanto Fund Donates $20,000 for Molokai Watershed Protection

Monsanto Fund Donates $20,000 for Molokai Watershed Protection

Monsanto Molokai News Release

The Monsanto Fund awarded a $20,000 grant to The Nature Conservancy (TNC) of Hawaii for watershed protection at Kamakou Preserve on Molokai. Since 2006, the Monsanto Fund has contributed a total of $130,000 to TNC’s protection and restoration efforts of critical watershed and fragile ecosystems on Molokai.

Located high in the mountains of East Molokai, the 2,774-acre Kamakou Preserve is a rainforest like no other on the planet. This magnificent natural treasure not only shelters hundreds of native plants and animals, but also serves as an important source of water for the island and its people.

TNC’s work at Kamakou Preserve, in collaboration with the public and private landowners of the East Molokai Watershed Partnership, is focused on invasive animal and weed control.

“Molokai’s forested watersheds today are under constant assault from established and new invasive species,” said Ed Misaki, TNC’s Molokai Program Director. “Feral ungulates (hoofed animals) like wild pigs, goats and deer are steadily eroding fragile topsoil. Once this soil disturbance occurs, invasive plants that did not evolve here, like blackberry and strawberry guava, steadily displace our native forests and watersheds. Once lost, they may be impossible to fully restore at any price.”

County Begins Deer Harvest Cooperative

Imagine higher agricultural yields, fewer invasive species, and a new economic product that’s as versatile as it is plentiful: venison. That was the vision of the founders of the Maui Axis Deer Harvesting Cooperative (MADHC), a new initiative organized by the County of Maui. Its goal is to help farmers, ranchers and landowners control invasive axis deer on their property while addressing food security with zero waste. MADHC members are a group of certified, trained, hunters who can provide harvesting services to those receiving damage from axis deer. The meat will be shared between hunters and landowners, and in some cases, local slaughterhouses will process meat for resale.

While the cooperative is already active on Maui, some Molokai residents are looking at the possibilities for the Friendly Isle — turning venison into a trademark specialty while helping out farmers with deer problems. Phyllis Robinson, one of MADHC’s founders and pilot coordinator, said it’s still early in the process, but her goal is to be able to incorporate Molokai and Lanai into the program.

“We’d like to plant the seed of awareness,” she said. “It could be helpful to have a coordinated effort county-wide but unique efforts on each island.”

Robinson said she has been in communication with Molokai axis deer rancher and hunter Desmond Manaba to explore the possibility of establishing an auxiliary board on Molokai to organize similar services on the island and be part of the cooperative umbrella.

Manaba, who has been deer ranching on Molokai for 18 years, said he sees tremendous potential economic benefit axis deer.
