A little off the main vein for NAFEX, but re Rubus as an invasive genus---- 
There is an experiment being run by our UW & Extension in southwest 
Wisconsin, studying rotational grazing by scots highland cattle.  A 
brousing-grazing breed.  Turns out they really set back all our Rubus !  
Native red raspberries, black raspberries, & black berries all will fill up 
a woods if not subjected to grazing, mowing, burning, other disturbance.  I 
don't think they are as much an issue as the Evergreen & Himalayan b.b.s.  
And I don't know if the same impact could be got from grazing in your 
climate.  But maybe rotational grazing is worth learning about.
