Would it be wrong if I reported my neighbor to the fire department without talking to him first?

I used to do yardwork at my neighbors house up until about a year ago. He had a fire pit that was just a few feet away from some brush. I'm worried that he's going to start a forest fire. He's kind of a scary guy if you get on his bad side so I'm afraid to bring it up, so I was just going to report it to the fire department. On the other hand, what If someone visited him recently like a friend or family member, and he thinks they reported him, and he blames the wrong person. That's a reason I might want to talk to him first, but I'm scared. My dad said I should mind my own business, but I feel it is my business, and my duty to do something.
