Galveston officials are investigating the torching of 30 palm trees in the last two months.
"What we've got on our hands, a serial tree arsonist, I've never seen before," said Galveston Fire Marshal Gilbert Robinson. "I've talked to colleagues of mine, and that's the first they've heard of setting palm trees on fire."
Robinson said the calls reporting burning trees have recently increased in frequency.
Tree service company owner Greg West is offering a $1,000 reward
for information that leads to charges.
"We just got hit by a hurricane, and the only thing that lived were the palm trees," West told The Galveston County Daily News. "I want to put the reward out, so it might change somebody's mind to turn them in."
The trees that weren't consumed by flames will live, but it could take years for the burned trunks to heal, West said. Many trees on the island have already died in flooding from Hurricane Ike in September.
A 40-year-old man carrying a gas can with only a residual amount of gasoline was arrested early Tuesday after he ran from police, Robinson said.
"After we apprehended him, a report of a palm tree fire did occur," Robinson said. "We're thinking there are possibly several people doing this."
The man was charged with fleeing police, a misdemeanor, Robinson
One car parked close to a burning tree was damaged, and utility lines have been replaced.
