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.

Some crabapple species are invasive, and though I see volunteer apples of
the cultivated species popping up here and there, here in Oregon, I wouldn't
call them invasive. The Himalaya blackberry IS invasive here, though the
fruit is quite good. The Evergreen blackberry is also invasive here.
Problem is, anything that might be brought in to control the invasive types,
(insects and diseases) would also attack the cultivated types, and they are
big business here, so the invaders keep spreading. Something that can layer
itself 20 feet from the original plant, come up from any root piece left in
the ground, and spread seedlings anywhere birds go HAS to be considered
invasive.

You asked...

ARE YOU IMPLYING THAT PROPIGATING APPLES ETC MAY NOT BE ETHICAL? THAT IS
SOMETHING THAT I HAVEN'T CONSIDERED.. WOW...DENNIS DAVIDSON ZONE 5 N.

I haven't found apples to be invasive in my area, although I suppose it's
possible somewhere else given the right set of environmental factors. You
have to know your own home place for what are weeds and what are not. In my
area (and many others) Autumn Olive/Russian Olive (Eleagnus spp.), European
Cranberry Bush (Viburnum opulus), and Japanese Barberry (Berberis
thunbergii) have edible fruits and are all generally agreed to be invasive
species. I suppose Multiflora rose (Rosa Multiflora) is edible too,
although a little bitter compared to roses with larger hips. There are also
the Himalayan blackberries all over the west coast and other places. Lots
of people don't mind these, but I know many west coast gardeners and
ecologists who battle it and insist its a big problem. Besides, the
cultivated varieties of blackberries really do taste better anyway and are
usually not quite as agressive. Someone also had also mentioned something
about the rootstocks of bradford pears have been spreading around the New
England States...
