Feral pigs may usher nonnative plants into Hawaii – The Wildlife Society
The forest disturbance that foraging feral pigs cause on Hawaii’s Big Island may be helping nonnative plants take root.
“Areas that have higher pig density and soil disturbance tend to have a greater abundance of nonnative species,” said Michael Peyton, a PhD candidate at the University of Wisconsin-Madison.
Native Hawaiians first introduced pigs to Hawaii when they colonized the archipelago from Polynesia between the years of 400 and 1100. Explorer James Cook and subsequent visitors introduced European pigs starting in the 18th century. The hybridized descendants of these breeds uproot native plants and damage infrastructure.
In a study published recently in Functional Ecology, Peyton and his colleagues wanted to see how different densities of feral pigs (Sus scrofa) affected the disturbance of native plants on the Big Island of Hawaii.
They set up trail cameras in different parts of the Pu’u O Umi Natural Area Reserve in the north of the island—an area with a high degree of contiguous native forest. With help from land managers, they identified four areas with differing densities of pigs. After capturing images from these areas, they confirmed population densities with statistical modeling.
To get a good idea about the type of vegetation growing in areas with different numbers of pigs, the researchers conducted various types of analyses. In areas with camera traps, they recorded understory plant species and their abundance.
They categorized plant species on a spectrum based on whether the plants produced short-lived leaves with rapid growth, or hardier, long lived leaves with a slow growth rate.
Peyton and his team found that areas with more pig disturbance typically had a higher proportion of plants that produced lighter leaves more quickly.
Those are usually nonnative plants. Native Hawaiian plants are more often the type that produce hardier, heavier leaves.
While some fast-growing native plants grew in disturbed areas, it seemed that pig disturbance was correlated more with nonnative plants. These nonnative, fast growing plants are well positioned to take advantage of the disturbance from the swine.
“Native and nonnative species are responding differently to [pig] abundance,” Peyton said.
While further research would be needed to confirm this, Peyton speculated that sunlight availability may be one reason why certain plants do better than others, especially when there is a lot of disturbance.
“The scale of disturbance matters for how these species are responding to light,” he said.

Scientists say major earthquakes feel frequent, but activity is on track
HONOLULU (HawaiiNewsNow) – Over the last month, strong earthquakes of magnitude 6.0 and higher have rocked the Philippines, Japan, Venezuela, and even Hawaii.
Researchers have been closely monitoring the activity, and while it may seem like more quakes than normal, they say it’s about on par with forecasts.
“This is all pretty normal for earthquakes. On a given year, we expect around 15 between magnitude 7 and 8, and about 150 between magnitude 6 and 7,” said Helen Janiszewski, assistant professor at the University of Hawaii at Manoa’s Department of Earth Sciences.
The quakes are, however, hitting in more populated places compared to some large earthquakes in past years, making them more noticeable.
“A couple years ago, there was an actual very similar, sequence of earthquakes to the one that we had in Venezuela where it was, 7.8 and 8.1 in very close sequence, but it was here, where no one lives,” Janiszewski said, pointing to the Southern Atlantic Ocean on a map.
Despite advancements in technology, researchers say there’s still no way to precisely predict when and where the next big earthquake will strike. But some seismology enthusiasts believe patterns can be monitored, studied, and used to implement potential life-saving warnings.
“I think it’s something that could happen as well across the world if people, scientists got together and really understood what’s happening. And then governments also utilize this knowledge to better notify and warn their citizens,” Pahoa resident Bob Gentzel said.
There are upwards of 100 seismographs throughout Hawaii constantly monitoring for quake activity.
Very subtle energy from the Venezuela quake was mapped traveling through the continent.
Some hope investments will be made in early-warning technology, as well as individual emergency preparedness.
“I’m just trying to prove the point that they can be forecastable because I want to save lives,” Gentzel said.
Janiszewski added, “There’s a lot that we can do still in the interim, both on an individual scale for preparedness in your own home as well as investment at community and state levels.”

Hawaii overpays SNAP benefits by nearly 10% in 2025
HONOLULU (HawaiiNewsNow) – More than $10 billion in SNAP benefits paid nationwide in fiscal year 2025 were above recipients’ eligibility or went to people who didn’t qualify for the program, according to the U.S. Department of Agriculture.
An annual analysis shows the national payment error rate was 10.62%, well above the congressional threshold of 6%.
The error rate measures how accurately states determine who is eligible for SNAP and how much they should get.
In Hawaii, the payment error rate is higher than the national average at 10.92%
“These payment error rates are further proof that state accountability is severely lacking in SNAP,” Agriculture Secretary Brooke L. Rollins said in a press release. “USDA has taken historic action to help interested states curb SNAP waste, and I hope other states, regardless of political leadership, prioritize needy families and the American taxpayer over politics.”
States above the threshold must now pay back a percentage of their benefits and submit an action plan to the USDA explaining how the errors will be addressed.
