In SW Ohio and North Carolina where I worked Buckthorn is not really something that anyone has ever had contact with. However, in the states where it is common, it's doing the same thing that Chinese Honeysuckle is doing, say, in Ohio. Where are you?
Controlling it is tough- you can choose between controlling mechanically or chemically. Either way requires a prolonged effort. In your situation, the most responsible thing to do is to keep it from developing fruit. That's the stuff that birds eat and then poop out three miles away, which then establishes it somewhere else. So, now would be a good time (I think it sets fruit late) to prevent it from creating more seeds.
Basically, the message is to get at it and try to prevent seedlings. The mature plants need to be cut to the ground, but smaller ones can be yanked out of the ground. I am glad you are interested in this- invasive species like this can ruin the forest.
