COLLIER COUNTY, Fla.- Fire crews are fighting a 50-acre fire in Collier County that is 75 percent contained. 

The fire has been difficult to extinguish because it is so deep in the woods off of Collier Boulevard behind the Verona Walk community.

Crews had to use a dirt road to access the fire. It was far enough from homes that it didn't post any threat to the community.

Division of Forestry says the fire is spreading away from the homes in this community.

Since there is a lot of dense vegetation, three bulldozers, a hellicopter and an airplane are being utilized in putting out the fire. A few fire departments are assisting as well. 

A definitive cause of the fire is unknown, however, Division of Forestry says it may be a result of lightning.
