I would encourage you to contact your Northern Ireland Forest Service, just to be sure, of how long you maybe allowed to go camping, especially if it is not a designated camping ground. I read some of your govt's websites, and there are specific regulations. Best to know what you can and cannot do if you really plan to go on extended camping there.
I read too, there has been a report of squirrel pox outbreak in one forest park there sometime 2016, just check where it stands right now.
