First post, so if this sounds way out in left field just ignore.

It has always been my understanding that LMB populations, regardless of strain, will populate to complement their food source. Could it be that if you just continue to wait, the F1's will simply continue to populate until they compete with themselves for the available forage in the BOW?

At the time when they start to overpopulate, you would need to do some intense harvesting to keep things in check. Which would be easy since at that time the population will have started to put a strain on the forage availability, creating competition for anything that looks like food.

We are looking at purchasing some property soon that will be prime for a ~30 acre watershed lake. I'm reading everything I can so that maybe one day.........
