The Big Drip: Possible Water and Soil Impacts of the Miconia Invasion in Hawai‘i

Posted on May 10, 2012 by MISC 1 Comment

By Thomas Giambelluca

Anecdotal evidence suggests that, besides impacting biodiversity, the invasive tree Miconia calvescens is causing landslides and other soil erosion problems in Tahiti, where it has displaced native forest. As miconia takes hold in Hawai‘i, local scientists and environmental organizations have voiced concerns about its potential hydrological impacts: increased flooding, diminished groundwater supply, loss of topsoil, and siltation of coral reefs.

Miconia invasions lead to dense, monotypic stands with little or no ground-covering vegetation. Miconia’s large, dark leaves reduce light levels beneath the canopy, thereby inhibiting the germination and growth of other plant species. Large leaves also produce relatively large throughfall drops during and after rain events.

“Throughfall” refers to rainwater that reaches the forest floor. Some throughfall consists of raindrops that fall through the forest canopy without hitting any leaves or branches. The rest comes from drops that splash or drip from wetted vegetation. Water that drips from the leaves of tree canopies can be much larger than raindrops. If falling from a great enough height, these large drops can reach kinetic energy levels that exceed that of natural rainfall in open areas. Because these large drops hit the ground with greater force, they can result in greater impacts to the soil.

The soil surface, exposed due to the lack of ground cover, is vulnerable to higher rates of “detachment,” the breakup of clumps of soil into small particles. Mobilized by large, high-energy throughfall drops, these particles can clog soil pores and reduce rates of infiltration. This leads to overland flow during rainfall events, a process unlikely to occur on undisturbed soils of native forests on Pacific Islands.

In a pilot study funded by the U.S. Fish and Wildlife Service we were able to verify that light levels under miconia stands in Onomea on Hawai‘i Island are very low.* Based on a limited survey, we also observed ground cover to be very sparse under miconia, with very little live vegetation and meager leaf litter. Most studies have shown that runoff and soil erosion become severe as ground cover declines below fifty percent, as was the case for the Onomea miconia stands.

Using laser disdrometers, Japanese researcher Dr. Kazuki Nanko helped us measure the size and velocity of throughfall drops under miconia and other tree canopies at Onomea and nearby field sites. Dr. Nanko found that miconiaproduced throughfall drops up to seven millimeters in diameter, much larger than typical two-millimeter diameter rainfall drops and significantly larger than throughfall drops under native trees.

Large miconia leaves act as umbrellas, shading out sunlight

The next step in this research is to observe runoff and erosion processes at miconia plots and control sites. Due in part to the effectiveness of miconiaeradication efforts in Hawai‘i, we have not been able to find stands large enough and in proximity to appropriate control sites to do the research in Hawai‘i. It is therefore likely that further study of hydrological impacts of miconia will be based in French Polynesia, where the miconia invasion is much more advanced.

Thus far, our studies indicate that in areas invaded by miconia, the effects of sparse ground cover, high-impact throughfall, and overland flow could combine to produce excessively high rates of soil erosion. Accelerated soil erosion removes topsoil, depriving native plants of access to nutrients and water and leading to siltation of streams and the near-shore marine environment.

Thomas Giambelluca is a professor at the University of Hawai‘i at Mānoa, where he has been conducting research on the climate and hydrology of Hawai‘i and other tropical areas for nearly 30 years.

Moving on from the Mongoose: the Success of Biological Control in Hawai‘i

Posted on April 18, 2012 by Lissa Strohecker 2 Comments

Achieving balance–in your workplace, at home, on your surfboard, or with your checkbook—makes life manageable. Natural environments depend upon balance as well.

Invasive pests have been disturbing the natural balance of Hawaiian ecosystems for centuries, ever since the arrival of the rat with early Polynesian explorers. Bringing invasive species into better balance with the environment is nothing new here in Hawai‘i. An effective biological control, or natural predator, can transform a devastating invasive species into a mild pest.

The invasive Erythrina gall wasp that threatened the native wiliwili trees, such ans this one, was brought into balance by a parasatoid wasp.

The vast majority of biological control efforts in Hawaii have been successful: pānini cactus that once choked pasture land is now checked by three predatory insects and a plant fungus; white loosestrife or pāmakani is continually attacked by two insects and another plant fungus; and recently, the Erythrina gall wasp, that wiped out ornamental coral trees and threatened the native wiliwili with extinction, was leveled by a parasitoid wasp.

Yet, just as impulsive actions sabotage balance in our own lives—think diet fads and over-exercising–the same kind of recklessness results in greater instability in our environment.

Such is the case with the small Indian mongoose, Herpestus javanicus. In 1872, a sugar planter released nine mongoose on Jamaica with the hope it would control rats in cane fields. The planter considered it successful and published a paper about it. Mongoose populations grew and offspring were sold to plantations throughout the Caribbean, Cuba, and Puerto Rico. In 1883, Hawai‘i plantation owners jumped on the mongoose bandwagon. With little regard for potential impacts, the now defunct Hilo Planters Association released seventy-two mongoose from Jamaica in Hilo. Another batch of mongoose from eastern India was brought to the Hāmākua coast in 1885. Subsequent offspring were released on Maui, O‘ahu, and Kaua‘i. For an unknown reason the crate delivered on Kaua‘i was kicked off the dock. To date mongoose have not established on Kaua‘i, though a single female was found killed by a car in 1972.

The mongoose is an opportunistic predator, introduced to Hawaii in 1883 with little regard to potential impacts on species other than the rat. Today, a potential biological control goes through years of testing to ensure it will have no unanticipated impacts.

Mongoose do eat rats, in Hawai‘i and elsewhere, but mongoose are opportunistic predators eating primarily insects, with birds, eggs, and a handful of plants mixed in. Additionally, mongooses are active during the day, rats at night. The introduction of the mongoose further tipped the balance of the environment in the wrong direction: now both mongoose and rats threaten populations of native birds, particularly ground-nesting species like nēnē and petrels.

The mongoose introduction was not an example of classical biological control; it was an impulsive, untested whim. Today, when researchers look for biological controls for a particular pest, they survey the pest’s native habitat for species that counteract the pest’s invasive characteristics. Before any new organisms are introduced in Hawai‘i, they are subjected to intensive testing in quarantine to determine potential impacts on any other species.

Successful candidates for biological control have evolved over millennia alongside their target; some are dependent solely on the target species for survival. For example, the Eurytoma wasp that saved the wiliwili will die without access to Erythina gall wasps. Consequently, Eurytoma populations will stop short of entirely eliminating the Erythrina gall wasp. Rather it will restore balance, keeping the pest wasp in check.

When mongoose were brought to Hawai‘i, there were no restrictions on plant and animal imports. Impacts on other species were an afterthought, if considered at all. It wasn’t until King David Kalākaua enacted the “Laws of the Hawaiian Islands” that any regulation existed to limit the introduction of new species to Hawai‘i.

Government-led pest management didn’t begin until ten years after sugar growers introduced the mongoose. The provisional government appointed Albert Koebele as the chief entomologist, the first of many tasked with preventing new and controlling existing pest populations

Biological control has a long and successful history in Hawai‘i. In fact, California and Hawai‘i lead the world in successful releases of natural predators. Ever since testing of biological controls began, there have been no incidences of “host-jumping” or biological controls attacking other species. Yes, the infamous mongoose ran amok, but it arrived during an “anything goes” era in Hawaiian history. The mongoose–or any opportunistic predator–would never be considered suitable for introduction by today’s standards. Biological controls are an important tool—sometimes the only tool—that can restore balance in Hawaiian ecosystems.

Grow bananas? Guard against BBTV.

Posted on March 15, 2012 by Lissa Strohecker 2 Comments

In the spring of 2009, Angela Kepler found a diseased banana plant on her neighbor’s property. “It really freaked us out! As soon as we found out we ran next door and sprayed for aphids.” The neighbor’s banana plant was infected with banana bunchy top virus (BBTV). “BBTV is the worst,” Kepler explains. “Now we help check everyone in the neighborhood.”

Angela Kepler and Frank Rust study bananas. Of the 32 different kinds on their property, most are rare Polynesian bananas collected from the wild or someone’s backyard. They photograph and observe each plant from keiki to fruiting to learn the key characters that make each type unique. Kepler and Rust are writing a book on how to identify different types of bananas. They know what BBTV can do.

BBTV is the most serious known disease of bananas. Infected plants produce shrunken, malformed leaves and distorted fruit—if they fruit at all. BBTV eventually kills all plants in an infected mat (root mass)there is no cure for the disease. Removing infected plants and preventing spread is the only control for BBTV—a necessary precaution if bananas are to continue being grown in Hawaii. BBTV threatens the banana industry, backyard farmers, and rare, culturally significant banana varieties, such as those grown and collected by Kepler and Rust. “We’ve seen a tremendous demise in the last 10 years,” says Kepler.

BBTV is spread between plants by banana aphids. The virus is passed from an infected plant to the aphid and transmitted when the aphid feeds on a healthy plant. People then spread BBTV great distances when they transport infected plants. Anyone who moves or harbors infected plants puts their neighbors’ plants at risk.

Banana bunchy top virus is widespread in Southeast Asia, the Philippines, Taiwan, the South Pacific, and in parts of India and Africa. It was first discovered in Hawaii in 1989. BBTV is widely established on O‘ahu and has been detected on Hawai‘i Island, Kaua‘i, Maui, and Moloka‘i. “We haven’t been able to collect bananas from other islands, or share ours due to BBTV,” says Kepler.

On Maui, backyards in Kīhei and Pukalani suffer the densest infestations of the disease. Banana farms in Kula and, most recently, central Maui have been wiped out. Not surprisingly, BBTV thrives in Lahaina as well; drier climates are better aphid habitat. Scattered infestations of BBTV have been found in Ha‘ikū and Huelo as infested material has been brought into the area. To date, Hāna, Ke‘anae, and Kipahulū are free of BBTV.

Another indication of BBTV infection is a sporadic dark green streaking, as if in a Morse-code pattern along the leaf sheath. MISC file photo.

Controlling and preventing the spread of BBTV is everybody’s business. If you have banana plants check them regularly for symptoms of the disease. Initial signs of infection are: 1) dark “Morse code” streaks along the leaf stem named for the irregular pattern of dashes and dots along the veins, 2) “J-hooks’ where the leaf veins along the blade of the leaf curve into the midrib. As the infection becomes established, new leaves emerge with difficulty, giving the plant the appearance of having the “bunchy top” that the disease is named for. New leaves are narrow and lance-shaped, often with yellowing around the leaf edges. Plants will stop producing fruit after infected and any keiki from the infected mat are severely stunted.

Check for “J-hooks” along the midrib of the of the banana leaf. This is a symptom of BBTV infection. Photo Courtesy of Scott Nelson, UH-CTAHR.

Controlling the spread of BBTV requires control of the vectors: aphids and movement of infected plants. Regularly spraying your plants with soapy water controls the banana aphid and can help prevent infection. The Maui Invasive Species Committee can help you identify infected plants and will control them for you. Infected plants should be killed on site and left standing until completely dead, typically within six months of treatment. Removing infected plants reduces spread of BBTV; aphids won’t feed on infested plants. Healthy bananas can be replanted in the same place after the mat has completely died.

If you suspect your banana plants are infected with BBTV and live in Maui County, call the Maui Invasive Species Committee at 573-6472. Due to the risk of BBTV, banana plants should not be moved between communities. “We all want to share bananas. People want to give each other plants, but don’t bring bananas from O‘ahu, Hawai‘i Island, or Kaua‘i,” cautions Kepler. “And whatever you do, don’t take bananas to the Hāna and Kipahulu area.”

Native plant growers throughout Hawai‘i replace IHOP’s “The Lorax” themed seed bookmarks with native plants

Posted on March 12, 2012 by Lissa Strohecker Leave a Comment

From March 9th, 2012 press release

HONOLULU — Hawai‘i theater goers enjoying the new movie, “Dr. Seuss’ The Lorax,” and its theme of protecting local tree species can help honor that message by supporting the use of native Hawaiian plants rather than non-native species.

To that end, the Department of Land and Natural Resources (DLNR) worked with local IHOP managers and the IHOP corporate headquarters in California last week to voluntarily discontinue the distribution of promotional bookmarks embedded with seeds at Hawai‘i IHOP locations.

“Thanks to the quick action of DLNR and others involved, we have turned a potentially negative situation into a positive one by expanding on the movie’s underlying message of being better stewards of our natural environment,” said Governor Neil Abercrombie. “The collaborative effort to discontinue the distribution of spruce seeds engages those who may not be aware of the importance of the ‘right plant in the right place.’ Our forests will thrive with more native flora and that benefits all of us.”

The bookmarks are part of a promotional campaign for Universal Pictures’ new movie release, “Dr. Seuss’ The Lorax,” in which IHOP customers are being encouraged to help the Lorax by planting trees. The bookmarks are embedded with Engelmann spruce seeds, which are native to parts of the U.S. mainland but not to Hawai‘i.

IHOP in Hawai‘i has voluntarily discontinued distribution of seeds, and the DLNR and the Coordinating Group on Alien Pest Species have partnered with native Hawaiian plant nurseries to create an exchange program so that any Hawai‘i resident IHOP customers who may already have received a seed-laden bookmark can exchange their spruce seed bookmark for a free native Hawaiian plant.

While the specific species included in the bookmark may not pose a high risk to Hawai‘i’s native plants, other species of spruce trees have been observed to be invasive in parts of the Pacific, where they replace native plants and the animals that depend on them.

IHOP’s corporate office demonstrated its commitment to protecting the environment by also discontinuing this promotion in Puerto Rico and the U.S. Virgin Islands, where Engelmann spruce is also a nonnative species.

“We want to be responsible caretakers of our environment. When we learned that the trees in question would not be the best choice for Hawai‘i, we responded quickly. We hope our guests will take advantage of this exchange opportunity,” stated Patrick Lenow, spokesman for IHOP Restaurants.

First published in 1971, Dr. Seuss’ The Lorax is a fictional story of a pristine environment where truffula trees provide food, clean air, and habitat for a community of unique animals. As they are overharvested to extinction, the Lorax tries to point out the environmental importance of the trees, but to no avail. The animals leave and the environment is left in ruins. However, the end of the story is one of hope: replant the truffula trees to restore the environment.

“Updating the message of The Lorax to include the value of native species is key for the next generation of conservationists to understand the problems facing our environment,” said Joshua Atwood, coordinator for the interagency Hawai‘i Invasive Species Council housed at the DLNR.

“An important part of The Lorax story is that the truffula trees grow nowhere else, and the Lorax is there to protect that limited resource. Similarly, many of Hawai‘i’s native plants and animals only exist on these islands, and we need to do what we can to protect them. That includes planting native, rather than nonnative, species whenever possible.”

One of the nurseries providing plants for the exchange is Hui Ku Maoli Ola, the largest native Hawaiian plant nursery in the state. “We believe in the importance of perpetuating our native flora as a part of our unique culture and environment,” said Matt Kapaliku Schirman, Hui Ku Maoli Ola co-founder. “This is a great opportunity to help protect and restore the Hawaiian environment.”

DLNR also thanks the Native Nursery and Big Island Plants or Ku ‘Oh‘ia Laka, whose exchange agreements were facilitated by the Maui and Big Island Invasive Species Committees.

IHOP customers who received a Lorax bookmark can exchange the seed-embedded bookmark for a native Hawaiian plant free of charge through the end of April, 2012 at the following participating nurseries:

In anticipation of “The Lorax” movie opening March 2, a national restaurant chain has been giving away bookmarks with seeds of blue-spruce and Canadian white pine.

A press release dated February 21^st 2012 explains the program: “In keeping with the animated adventure’s theme that one person can make a difference, IHOP is distributing three million limited-edition bookmarks embedded with seed paper that can be planted to flourish across a range of climates and forest condition.”

It’s great to encourage kids to plant trees. Unfortunately these aren’t the Truffula trees that the Lorax fought to protect. Planting alien trees in Hawai‘i can be tricky. The characteristics of the bookmark trees that allow them flourish across a range of climates and forest conditions can also help them invade and outcompete native species. In Hawai‘i pines have a reputation of escaping cultivation into high-elevation ecosystems. Think twice before planting these pines in our forests. As the voiceover from the movie trailer says when the boy receives the last seed of the Truffula tree, “It’s not about what it is, it’s about what it can become.”

After concerns were raised, distribution of the seeds was discontinued in Hawaii.

Make the Lorax proud and plant a tree that is regionally appropriate to the area. Find suggestions of native Hawaiian plants here: www.nativeplants.hawaii.edu

And on a final note: ever notice how a lehua blossom on an ‘ōh‘ia looks a bit like a Truffula tree?

Make National Invasive Species Week Last All Year

Posted on February 24, 2012 by Lissa Strohecker Leave a Comment

National Invasive Species Week is February 26 to March 3 of 2012. While it’s great to pay attention for the week, here are a few simple actions, one for each month, to help make a difference on the invasive species front:

*Note: This list was originally published in the January 8th edition of the Maui News.

Start by removing invasive species in your own back yard, like this ornamental pampas grass.

January—check backyard first. Take a look in your own yard to see what invasive species you might be harboring– then remove ‘em! Backyards are often the source for plants and animals that escape to wreak havoc in our environment. If the plant or animal is a target for the Maui Invasive Species Committee, such as pampas grass or coqui frogs, call us and we’ll give you a hand.

February—be pest-savvy. The last week of February is National Invasive Species Awareness week. Take part by learning about a new invasive plant or animal and how to control or report it. Start at mauiisc.org, mauiinvasive.org, reportapest.org, or check for monthly editions of this column, then share what you know.

March—buy local—Maui local. Many pests are limited to just one island, but they spread when potted plants, cut flowers, equipment, even produce is moved between islands. Support Maui’s economy and protect our island by bringing home locally grown products. Avoid ordering seeds on the Internet as some plants may be invasive in Hawaii.

Clean your gear-boots, fins, packs, and cars-regularly to prevent the spread of hithchiking invasive species.

April—clean your gear. Headed out diving, snorkeling or hiking? Give your gear a thorough rinse or scrub to remove any hitchhiking seeds (check the tongue of your boots), algae, or insect eggs before you head out. And don’t neglect to check your car periodically, both the underside as well as the inside.

May—volunteer. You will meet interesting people and learn more about Maui. Many groups have weekend volunteer trips where you can lend a hand removing invasive species or planting native species. Find an organization at hear.org/volunteer/maui/

June—survey your yard for the little fire ant. This tiny ant often arrives unnoticed, but it can become a huge problem. Currently no known infestations exist on Maui, but there is a high likelihood they will arrive again. Surveying is as easy as peanut butter and a chopstick. Learn more at lfa-hawaii.org

July—travel smart. Check twice before you bring something interisland. Plants and plant cuttings must be inspected by the Hawaii Department of Agriculture before being taken interisland to ensure there are no unwanted pests or diseases riding along.

August—take a hike, but with new eyes. Public reports are one of the best ways we learn about new invasive species. So cruise around the neighborhood, or go for a walk in the forest. See a bird you’ve never seen before or a new plant that looks like it’s taking over? Take a photo and let someone know.

September—be neighborly. Some invasive species problems are too big to tackle alone, but left unchecked will become everyone’s problem. Offer to help out your neighbors with an invasive species in their yard.

October—go native in your yard. Hawaiian plants have never been more available for landscaping. In addition to being a unique addition to your landscape, these species won’t be invasive and offer habitat for native animals. Another plus – these plants evolved to survive on rainfall, so when selected to match your climate, they can help you save water.

November—eat an invasive. The season of eating offers plenty of edible invasive species, from axis deer to pigs to. Make a meal, or part of a meal, in the spirit of removing invasive species. For more information (and recipes) check out invasivore.org.

December—celebrate in holiday style with an invasive pine tree. Each year Friends of Haleakala National Park and The Nature Conservancy lead December trips to remove invasive pines from areas in and near Haleakala National Park. Find details for the Friends trip at fhnp.org and for the TNC trip by calling 572-7849. Other trips may be listed in the newspaper.

This year make a resolution to help address invasive species— just one simple activity a month can add up to make a big difference in our community.

Give your loved one the gift of local this Valentine’s Day

Posted on February 13, 2012 by Lissa Strohecker Leave a Comment

Flowers. When it comes to courting your Valentine, you gotta have ’em. Roses may be the standby for the holiday, but don’t overlook the beautiful, locally grown cut flowers available. This year, express your love for Maui as you woo your Valentine with a creative choice of flowers.

The locavore movement is nothing new; eating locally grown food has steadily gained support over recent years with restaurants highlighting Kula greens and Maui onions. Buying other products grown on Maui, like flowers presented on Valentine’s Day, is yet another way to help our community by preventing the import of invasive species and growing the local economy.

Like agriculture, the floral industry has become increasingly globalized. During just one week in February 2008, flowers and foliage shipped to Maui came from Columbia, Italy, Thailand, New Zealand, the Netherlands, Ecuador, Peru, California and Florida. Some shipments are refused or incinerated at the Hawai‘i Department of Agriculture inspection facility because they carry pests and diseases not known to be in Hawai‘i. But consumers can help stem the introduction of hitchhiking pests.

“If we can buy locally grown things, there is less risk of invasive species being spread and it helps local businesses,” explains Glenn Sakamoto, training and education specialist with HDOA.

Carver Wilson of Maui Floral knows firsthand about the hitchhiking pests carried in cut flowers and foliage. He and other florists throughout the state have voluntarily cut back on their use of eucalyptus and wax myrtle as foliage in arrangements. These plants in the myrtle family are imported from out-of-state and are the likely culprit for bringing in the invasive ‘ōh‘ia rust that spread quickly, killing rose apple trees throughout the state. “The rust is a detriment, so we chose to use something else,” Wilson says. The Hawai‘i Department of Agriculture is in the process of pursuing a permanent ban on the import of myrtle plants to protect against new strains of the rust out of concern for protecting native ‘ōh‘ia.

Some of Wilson’s suggestions for locally grown bouquets: Orchids, pincushion or king protea, anthuriums and ginger. These flowers are symbolic in their own right. Orchids represent love, luxury, beauty and strength; proteas represent diversity and courage; and anthuriums, hospitality.

To highlight the Hawai‘i floral industry, HDOA featured a bouquet of locally grown possibilities at last year’s Maui Agricultural Festival. Working with growers on Maui and the Big Island, HDOA showcased fabulous floral arrangements by professionals and offered festivalgoers the opportunity to create their own works of art using locally grown flowers. A similar event was held on the Big Island.

The events are one part of an effort to encourage replacing imported goods with Hawai‘i-grown products. This year consider where your flowers are coming from; it’s an opportunity to help protect Hawai‘i from invasive pests while showing a little love to your local flower grower and your loved one. As Wilson says, “I absolutely support and suggest people use locally grown flowers; it helps us all.”
