I am a slim male, mid 30's and i have a big belly. are there any specific exercises i could do at home that would target that area?

Maybe, but...: Once you've ruled out abdominal wall hernia, the only way to effectively spot-reduce unwanted abdominal tissue is to surgically remove it. The "pear" body type preferentially stores fat around hips; "apples" store it around their waist. Lose 1 pound of fat for every 3500 calories you drop or exercise off, but you can't pick where--sorry. Abdominal exercise will improve tone of existing muscles.

Well, no. : There are no specific exercises to reduce your belly. Even though you are slim, if you have a large belly, that means you have a lot of intraabdominal fat, which is particularly unhealthy. A sensible fat reducing diet that is fairly high in protein (to help you build muscle) coupled with lots of exercise should decrease fat overall and increase muscle.
