Maybe somehow tie social media to the forum? I think that's the trend these days too and a lot more sites and companies are doing that.
Social media to draw in visitors
Forum for a community to develope
I can't remember but do you have a YouTube channel? Maybe film wolves' daily life, etc. Some creative contents would definitely draw more visitors.
There's thousands, if not, hundreds of thousands of people watching cat videos online every day. lol. So the audience is certainly there.
