Mahalo for the opportunity to testify in strong support of this pressing environmental issue, and weigh
in on its impending impacts to the County and overall context of the State. This measure will prohibit
the feeding of stray or feral non-native animals on County -owned property, recognizing this as a critical
step toward protecting Hawaii's fragile ecosystems, safeguarding public health, and aligning County
policy with State Biosecurity objectives. Feral non-native animals pose a significant threat to the State's
Native species. While these harms are not always immediately visible to the human population, the
cumulative toll will critically undermine the stability of our native ecosystems, affecting biodiversity,
water quality, and cultural resources tied to native flora and fauna.
Feral, non-native animals pose a significant and well -documented threat to Native Hawaiian species,
many of which exist nowhere else in the world. According to the U.S. Fish and Wildlife Service, Hawaii
accounts for over 44% of all endangered and threatened species in the United States, despite
comprising less than 0.2% of the nation's landmass. Key native species at -risk include the Hawaiian monk
seal, the nene goose, and numerous native forest birds imperiled by predation, competition, and disease
transmission from feral cats, pigs, goats, and other non-native species.
Of particular concern is toxoplasmosis, caused by the parasite Toxoplasma gondii, which can only
complete its reproductive cycle within felids. Feral cats, which are widespread across Hawaii Island,
excrete environmentally persistent oocysts in their feces, contaminating watersheds and nearshore
environments. The Department of Land and Natural Resources reports toxoplasmosis as a leading cause
of mortality in the Hawaiian monk seal, accounting for over 12% of diagnosed deaths between 2001 and
2023. In nene, toxoplasmosis often proves fatal due to a lack of viable and effective treatment options,
contributing to the already precarious status of these endemic species.
The prohibition on feeding feral animals on County lands will reduce artificially sustained feral animal
populations, limiting breeding success and aggregation that accelerates disease transmission and
environmental degradation. This policy aligns with State of Hawai'i biosecurity objectives, which
recently received significant funding support: in the FY 2024-2025 State budget, the Hawai'i
Department of Agriculture's biosecurity efforts were increased by $20 million to enhance interagency
invasive species control, rapid response, and containment measures statewide. This County -level action
complements State investments and reflects an integrated approach necessary for effective biosecurity.
From a fiscal standpoint, reducing feral animal populations can mitigate the high costs of invasive
species management, which the State estimates at over $50 million annually, and the additional

environmental and economic costs of species extinction, disease management, and the impact on
tourism and agriculture.
In conclusion, Bill 51 is a prudent, proactive policy to protect Hawaii Island's natural resources, uphold
our environmental stewardship responsibilities, and reduce the significant threats posed by feral non-
native animals to Native Hawaiian wildlife and public health. By enacting this measure, the Council will
help safeguard our endangered species, reduce disease risk, and align with the State's investment in
biosecurity and conservation, ensuring a healthier and more resilient Hawaii Island for future
generations.
Mahalo for your consideration of this testimony in strong support of Bill 51.
