What about rosa rugosa?  Is it native?  (Not, according to Wiki)  It =
seems at least as widespread as multiflora.

  Most store roses are grafted unto a rootstock David.=20

The rootstock will be undefined in most cases but we know

Multiflora roses are popular for good reasons! The grafted

part - top - will usually be inferior in hardiness and other aspects to

the rootstock so the top dies - the roots send up shoots and then

you have a Multiflora rose ready to go!

You can obtain roses on their own roots - hardy roses that is  - but

not at the local store!

Enjoy the rain - it will help the roses.

Another "David" here. An interesting, worthwhile debate. A few thoughts. =


 =20

Multiflora rose, while it had been here 100 years and more, seems to =
have taken off recently as an invasive in NS (or in a new wave of =
invasiveness)  sometime after 2000. Did that stem from threshold changes =
in disturbance or vehicles of movement, or did a particular line have =
traits that make it especially invasive (or some combination of the =
two); it seems a genetic study could sort that out. Are there less =
invasive strains that could be used as ornamentals/to attract and feed =
birds?=20

 =20

I have conducted some documentation of the spread of R. multiflora in =
the Halifax area, Point Pleasant Park in particular. See =
versicolor.ca/multiflorarose <http://versicolor.ca/multiflorarose>   =20

 =20

We might  keep in mind that about 1/3 of our flora is of exotic origin =
at least in recent centuries, and mostl of these species are plants of =
disturbed habitats, perhaps all (except (glossy buckthorn?) are not =
shade tolerant; their introduction since European colonizations reflects =
 the greater abundance of ruderal species in Europe & Asia because of a =
longer history of extensive human disturbance than in NA. On the whole =
these immigrants  perform important ecological functions and do not =
seriously threaten native plant communities. (Surely the loss of weedy =
species under our now super efficient glyphosate weed control is a big =
factor in decline of many species). Perhaps where they do threaten =
native plant communities in NS that is a transient process as it likely =
was for many of the exotic species for a period after they first =
arrived. =20

 =20

NS is likely species depauperate because of the short time since the =
glaciers retreated and our relative isolation as a peninsula on the =
Atlantic coast, so in a sense we are "open for business" when it comes =
to immigration of new plant species. I think we should be very actively =
conducting Assisted Migration, particularly for forest species, to =
increase species diversity and resilience in the face of climate change. =
 Anyway, a few thoughts for the mix. =20

 =20

PS: I have spent some time cutting back multiflora rose  near The Bluff =
Trail trailhead, as it is still not abundant along the rails to trail =
BLT, and so far there are no exotics once you get 5 m into the trail, so =
it takes little effort at this point to keep it out. I do not have R =
multiflora in my back yard but if I could obtain a non-invasive type, I =
would welcome it both as an ornamental and as bird food.  I do not keep =
bird feeders because they  encourage everything I don't want, rats, =
squirrels and pigeons amongst them.=20

Why do birds have the only meaningful vote? That is simply ridiculous, =
David. Do our own native plants not have such a vote? I suspect that =
they would vote them "off the island", and occupy the space themselves.=20

 =20

I have actually thought about the SI Ponies. If SI is designated an =
historic site (is it?), then the ponies are part of the culture. There =
is no fear of them spreading anywhere. MR - is invasive.=20

 =20

We need to look at the big picture...not just that MR is "good for the =
birds" (when in fact it is only good for some birds). Our native roses =
are good for the birds in this context, too.=20

Hi Randy & All,=20

    In such matters the birds have the only meaningful vote and they =
have made their approval of MR very clear. In late winter, on calm sunny =
days, the nearby MR patch looks like Grand Central Station; much coming =
and going and the lawn becomes sprinkled with closely spaced red =
splotches. =20

 =20

    I suspect you are just pulling our leg Randy so in that vein, I =
suggest you should get that program to eradicate the Sable Island ponies =
in motion and when they are history, move on to eradicating MR; my =
patches dead last.=20
