NASA images reveal “ghost forests” in Florida


NASA and U.S. Geological Survey (USGS) satellite images have unveiled a concerning phenomenon in Florida: the emergence of “ghost forests” in the state’s mangrove ecosystems.

These watery graveyards of once-thriving trees are a product of mangrove forests’ increasing vulnerability to intensifying storms and environmental change.

Mangroves are vital to the Florida Everglades. Known for their picturesque, half-submerged roots that create natural tunnels for kayakers, these trees also serve essential ecological and environmental functions.

Mangroves stabilize coastlines, buffer against erosion, store carbon and provide critical shelter for marine life.

Florida is estimated to have 600,000 acres of mangrove forests, though their distribution has changed in recent decades mostly as a consequence of human activity, according to the state’s Department of Environmental Protection.

Although mangroves are renowned for their resilience, including their ability to withstand flooding, the recent findings published in the journal Remote Sensing of Environment revealed that stronger and more frequent hurricanes are overwhelming this natural adaptability.

Using decades of Landsat satellite data spanning from 1999 to 2023, researchers identified troubling patterns in mangrove recovery following hurricanes. Unlike previous studies that typically focused on single events, this study paints a broader picture of how these forests respond to storms over time.

The team categorized mangrove conditions into four groups: healthy (unaffected by storms), disturbed (impacted by storms but recovered within a single growing season), recovering (requiring more than one season to recover) and declining (failing to recover and entering long-term decline).

The aftermath of recent hurricanes revealed a sharp rise in the number of declining mangroves. These forests, unable to recover, often transition into “ghost forests,” where dead trees haunt the once bustling coastline.

“Our monitoring has shown a significant increase in the area of mangroves that have lost their natural recovery capacity following recent hurricanes, such as Irma in 2017 and Ian in 2022,” Zhe Zhu, a co-author of the study and a former member of the USGS–NASA Landsat science team said in a statement.

The Landsat-based maps from the study showed clear contrasts between mangrove recovery after hurricanes Wilma (2005) and Irma (2017) in the southern Everglades National Park bordering the Gulf of Mexico.

While most mangroves recovered naturally after Wilma, a significant portion of mangroves impacted by Irma entered a long-term decline, turning into ghost forests.

“Comparing post-hurricane conditions in Florida revealed that the increased frequency and severity of disturbances are challenging mangrove resilience, potentially diminishing their ability to recover and sustain ecosystem functions,” the researchers wrote in the study.

A key innovation of this study was the use of a machine-learning algorithm to analyze satellite data, enabling continuous and detailed tracking of mangrove conditions. This approach provides an early warning system, helping land managers identify areas at risk before losses become irreversible.

“Our research aims to provide an early warning system for mangrove decline, helping to identify areas at risk before irreversible loss occurs,” Zhu said.

The researchers plan to refine their algorithm to better differentiate between the drivers of mangrove change, such as extreme weather, rising sea levels or human activity. They also aim to expand the study to monitor mangroves globally.

“By identifying whether changes are driven by extreme weather events, rising sea levels, or human activities, we can provide more targeted insights for conservation and management strategies in a rapidly changing environment,” Zhu said.

Charges dismissed for woman without right hand cited for holding phone while driving

Charges dismissed for woman without right hand cited for holding phone while driving


A traffic citation issued to a woman who said she was accused of holding a phone in a hand she does not have has been dismissed.

Court records show the citation was dismissed at the request of the Palm Beach County Sheriff’s Office deputy who issued it. A court hearing had been scheduled for Tuesday, but was canceled after the case was dropped.

The citation, issued Feb. 11 along North Dixie Highway in Lake Worth Beach, accused the driver of violating Florida’s wireless communications while driving law. The case drew widespread attention after the woman posted video of the traffic stop on TikTok, where she questioned the deputy’s claim that he saw a device in her “right hand.” She said she does not have a right hand.

A Lake Worth Beach traffic stop is gaining attention online after a woman was cited for using a wireless communications device while driving, but video of the encounter is now sparking debate over how Florida’s distracted driving law is enforced.

The citation, issued by a deputy with the Palm Beach County Sheriff’s Office on February 11 around 8:04 a.m. along North Dixie Highway, lists the charge as “Wireless Comm. Device/Handheld While Driving – First Offense” under Florida Statute 316.305(3)(a), with a civil penalty of $116.

In a video posted to TikTok that has since gone viral, the driver records the stop and questions the deputy’s observation. The citation indicates the deputy observed a handheld device while she was traveling northbound on North Dixie Highway.

During the stop, the deputy is heard stating he saw the device in her “right hand.” The woman says she does not have a right hand and plans to challenge the citation in court. She has also requested body camera footage from PBSO. CBS12 has submitted a public records request for that footage as well.

What Florida law actually says

Florida’s Wireless Communications While Driving Law has been in effect since 2013 and was strengthened in 2019, making texting while driving a primary offense, meaning drivers can be pulled over solely for that violation.

Under the 2025 Florida Statutes, drivers may not manually type or enter letters, numbers, or symbols into a wireless communications device while operating a vehicle for non-voice communication, such as texting, emailing, or instant messaging.

However, the law includes several exceptions. Drivers are allowed to use a device for navigation or GPS purposes, receive safety-related alerts, report emergencies, and engage in voice communication that does not require manual typing.

“The statute’s actually really explicit,” Donahue said. “It says you have to be engaged in manually typing letters or numbers into the device.”

In other words, simply holding a phone is not automatically illegal under current Florida law outside of certain zones. The statute focuses on manually typing, entering multiple letters or numbers, or sending and receiving data while operating a vehicle.

Additionally, handheld use of a wireless device is specifically prohibited in designated school crossings, school zones, and active work zones. Attorney Ted Hollander with the Ticket Clinic says that distinction is key.

“Whether she’s holding it in her right hand or her left hand, it really doesn’t matter,” Hollander said. “If you are not in a school zone or a construction zone, you are allowed to hold a cell phone.”

Hollander noted that on this citation, neither a school zone nor construction zone box is checked.

“The fact that neither one is checked off tells me that this did not occur in one of those zones,” he said.

Enforcement and burden of proof

Hollander says it’s common for drivers to pay citations without questioning them — even in cases where the ticket may not hold up in court.

“So a lot of times people pay tickets that shouldn’t be paid, and this could have been one of those examples,” he said. “But luckily this lady seems to be standing up for herself.”

Donahue says enforcement can be challenging.

“It’s really difficult for the officer to prove that unless they visually see it or have it on their cameras,” he said. “That’s one of the reasons why you pretty much never see this infraction enforced.”

Donahue said that in his experience practicing traffic law in Palm Beach County, texting-while-driving citations are rare.

If a driver contests the ticket, the case would go before a traffic magistrate or judge. As a first offense, the violation is a non-moving civil traffic infraction punishable by a fine. A second offense within five years could carry points on a driver’s license.

Donahue notes that even though the statute is narrowly written, drivers should still exercise caution.

“You don’t want to be in a position where you have to prove your innocence,” he said. “Although the law is not that strict, you really need to treat it almost like it is.”

The woman says she has requested a hearing date and plans to fight the citation in court. PBSO has not yet responded to CBS12’s request for body camera footage or comment on the stop.

As the case moves forward, the viral video is reigniting discussion about distracted driving laws and how clearly they are understood by both drivers and officers.
