The Opossum Invasion: A Growing Threat too Hawaii’s Ecosystem
Table of Contents
Imagine stumbling upon a creature with a “head like a swine … tail like a rat … of the bigness of a cat,” as described by William Strachey in the early 1600s. For residents of Hawaii, this eerie encounter is becoming less of a rarity. Recently, a six-pound male opossum was captured at a big-box store in Kona, marking yet another chapter in Hawaii’s ongoing battle against invasive species.
This incident is not an isolated one. over the years, several opossums have been found in the islands, often hitching rides in shipping containers or cargo planes. These non-native marsupials, while less likely to carry rabies, are carriers of parasites and diseases that threaten Hawaii’s delicate ecosystem.
A History of Unwelcome Guests
The recent capture in Kona is just one of many. In August 2024, an opossum was found at a Kalihi freight company after workers spotted it darting into a shipping container. Just a month earlier, another was discovered on a window ledge in downtown Honolulu. These incidents highlight the growing concern about invasive species in Hawaii, as noted by KHON2 [[2]].
Here’s a rapid look at some notable opossum captures in Hawaii:
| Date | Location | Details |
|—————–|——————————————-|—————————————————————————–|
| August 2024 | Kalihi, O’ahu | Found in a shipping container at a freight company. |
| July 2024 | Downtown Honolulu | captured on a window ledge of an office building. |
| june 2016 | Honolulu Harbor | Discovered by workers offloading a cargo ship. |
| July 2015 | Kaka‘ako, O’ahu | Found near the U.S. Immigration and Naturalization Office. |
| August 2011 | Ward Centre, Honolulu | Uncovered in a shipping container during unloading. |
These incidents underscore the need for vigilance in preventing the spread of invasive species, which can disrupt local ecosystems and harm native wildlife.
The Opossum Problem: Why It Matters
Opossums, native to North america, are omnivores with diets ranging from insects and bird eggs to fruits and vegetables. While they may seem harmless, their presence in Hawaii poses significant risks. They compete with native species for resources and can introduce diseases that local wildlife has no immunity against.
As the Hawaii Tribune-Herald [[1]]reports, the captured opossum in Kona was humanely euthanized, a necessary step for rabies testing.This highlights the stringent measures Hawaii takes to protect its unique biodiversity.
What You Can Do
If you spot an illegal animal in Hawaii, it’s crucial to report it immediately.Call the statewide toll-free Pest Hotline at 808-643-PEST (7378). Your vigilance can help protect Hawaii’s fragile ecosystems from the threats posed by invasive species.
A Call to Action
The opossum captures in Hawaii serve as a stark reminder of the challenges posed by invasive species. As global trade and travel increase, so does the risk of introducing non-native animals to vulnerable ecosystems. By staying informed and proactive, we can all play a part in preserving Hawaii’s natural beauty.

The Opossum Invasion: A Growing Threat to Hawaii’s Ecosystem
Hawaii’s unique biodiversity is under threat from an unexpected invader: the opossum. These non-native marsupials, known for their scavenging habits, have been increasingly sighted across the islands, raising concerns about their impact on the delicate balance of Hawaii’s ecosystem.
World Today News Senior Editor Speaks with Dr.Lena Kalama, Invasive Species Expert
Dr. Lena Kalama, a leading researcher on invasive species in Hawaii, spoke with World Today News Senior Editor about the growing opossum problem and what it means for the islands’ future.
the Rise of the Opossum
Senior Editor: Dr. Kalama, can you shed some light on how opossums ended up in Hawaii?
Dr. kalama: Opossums are not native to Hawaii. Their presence here is entirely due to accidental introductions, most likely through shipping containers and cargo planes. They’re opportunistic travelers, and unfortunately, they can easily stow away undetected.
Senior Editor: We’ve seen a number of opossums captured in populated areas recently. how widespread is this issue?
Dr. Kalama: While opossum sightings were once rare, they’re becoming increasingly common, notably on the more populated islands. This suggests that they are establishing themselves and could potentially spread further if not controlled.
The Threat to Hawaii’s Ecosystem
Senior Editor: What are the primary concerns associated with opossums in Hawaii’s ecosystem?
Dr. Kalama: Opossums are omnivorous and highly adaptable, making them a significant threat. They compete with native animals for food and resources,and they can carry diseases and parasites that can harm Hawaii’s unique wildlife population.
Senior Editor: Are there specific native species that are particularly vulnerable to the impact of opossums?
Dr. Kalama: Yes, many of Hawaii’s endemic species, which are found nowhere else in the world, are highly vulnerable. opossums could prey on their eggs, compete for nesting sites, or introduce diseases that these species have no immunity to.
Tackling the Invasive Species Challenge
Senior Editor: What measures are being taken to address the opossum problem in Hawaii?
Dr. Kalama: Hawaii has a complete invasive species management program. when opossums are found, they are captured and humanely euthanized for rabies testing. Public awareness campaigns are crucial for encouraging early detection and reporting of sightings.
Senior Editor: What can the public do to help prevent the spread of opossums and other invasive species?
Dr. Kalama:
Vigilance is key.
Be aware of potential entry points for invasive species into homes and yards.
Inspect shipping containers and cargo thoroughly if you work in relevant industries.
* Report any sightings of unusual animals to the authorities immediately.
senior Editor: Dr. Kalama, thank you for shedding light on this crucial issue. What message would you like to leave our readers with?
Dr. Kalama: Hawaii’s unique ecosystem is a treasure that needs our protection. By understanding the threat posed by invasive species like opossums and by taking proactive steps to prevent their spread, we can all play a part in safeguarding Hawaii’s natural beauty for generations to come.
