Testimony in Opposition to Resolution 80-09 PWIR Committee Hearing: April 21, 2009 2:30 pm
Members of the Hawai'i County Council,
Aloha. The Conservation Council for Hawai'i strongly opposes Resolution 80-09 because we need all the
tools available to save our native Hawaiian forests for future generations. Biocontrol of invasive species - if
it is done carefully and safely - is an important tool we need to protect our natural and cultural resources.
Invasive species, such as strawberry guava, are one of the most serious threats to our watersheds, water
supply, water quality, unique Hawaiian plants and animals, agricultural crops and exports, food security,
recreation, public access, and use of mauka lands. It is unfair to allow strawberry guava to take over native
Hawaiian forests and trump the many benefits and uses of these lands.
Fortunately for you as elected decision-makers, this is not an "either-or" situation, and you can be fair to all
of your constituents. Some areas should be managed for native Hawaiian values and watersheds, and
strawberry guava should be removed from these areas. Other areas, such as marginal forest, fenced game
management areas for pigs, farms, and gardens could be managed for strawberry guava if desired.
Biocontrol of strawberry guava will give Hawaiian forests a chance to survive so that future generations can
enjoy them, and it will still leave more than enough strawberry guava for eating, making jelly, woodwork,
and any other conceivable use well into the future. There will probably never be a shortage of strawberry
guava in Hawaii. But we will lose our native Hawaiian forests, unique cultural plants and animals, and
watersheds if we do not take serious action now to address the strawberry guava problem. Please do not
repeat the coqui frog debacle where we knew about this pest, but county and state government waited too
long, and now we are probably stuck with it forever, at least on the Big Island.
Opponents of strawberry guava biocontrol continue to perpetuate many misconceptions about this proposal.
On the following page, we provide our response to these myths. We are also transmitting our strawberry
guava Call to Action. We hope this information is useful in your deliberations. Mahalo nui loa.
Sincerely,
Marjorie Ziegler

Biocontrol Myth Busters'
• Hawai`i's failure with the mongoose shows that biological control is unreliable.
The mongoose was introduced by a sugar planter in 1883 with no scientific testing or regulatory oversight.
Today, we require rigorous testing. Since 1975, 51 biocontrol species (including natural enemies for
clidemia, banana poka, and ivy gourd) have been introduced to Hawaii with no negative effects. A
biocontrol for the wiliwili gall wasp is currently being tested. A mistake made over a century ago has long
since been trumped by a decades long track record of success.
• Tectococcus ovatus could target other wild plants or crops.
In Brazil, T. ovatus has never been found on any agricultural crops, only strawberry guva and one other wild
plant (which is not found in Hawai`i). Likewise, researchers in Hawaii tested T. ovatus on some 80 related
native, commercial, and ornamental species. They confirmed that it only feeds on its host, strawberry guava.
• T. ovatus will rob our community of a source of food and wood.
T. ovatus will not kill strawberry guava, taint its fruit, or affect its wood. It will simply slow its fruit
production and spread. People will still be able to pick fruit and gather the wood, as Brazilians continue to
do in their forests where the trees are preyed upon by a far greater multitude of insects. Horticultural oils
used to control other scale insects can be used to protect homegrown trees if necessary.
• Populations of native birds and other animals that depend on strawberry guava will decline.
Strawberry guava is one of the greatest threats to native Hawaiian forest birds. It displaces native plants that
feed and shelter native birds, and invades their essential foraging and nesting habitat. Some non-native
animals, such as birds and wild pigs, eat strawberry guava and spread this invasive species, but none is
dependent on strawberry guava for its survival.
• If we control strawberry guava manually or chemically, we will not need biocontrol.
Strawberry guava infests hundreds of thousands of acres across our state. It produces billions of seeds
annually and spreads at exponential pace - often into steep or remote terrain, making manual or chemical
clearing dangerous and a temporary measure at best. After decades of effort, it has become clear that
biocontrol, used alone or with other methods, is our best and most economical option.
• Biocontrol of strawberry guava will clear large forested areas, causing erosion and encouraging
other invasive plants to move in.
T. ovatus will not kill strawberry guava, but impact stands of guava gradually, allowing more native species
to grow back and helping native forests to regenerate. Dense stands of strawberry guava' are more likely to
cause erosion, as they crowd out the understory plants that protect our soil, causing runoff and
sedimentation of our streams and nearshore waters.
• We should let strawberry guava grow because it could become valuable commercially as a biofuel.
Strawberry guava has not been identified as a potential biofuel in any serious commercial proposal in
Hawaii. The areas where we most want to control its growth would be difficult if not impossible to access
for commercial purposes. Even with T. ovatus; there will be more than enough wood for any conceivable
use well into the future.

also known as walawi, in Hawaii. Since its introduc-

has invaded Kauai, Oahu, Molokai, Maui, Lanai,

the amount of water flowing to our aquifers, and
spreading fruit flies to vulnerable crops.
