Hi List,
Sure seems like there are a lot of "accidental" CP plantings lately.
Please don't plant anymore weeds, like D.capensis and D.binata in CA,
or Sarr hybrids in PA, or Sarracenia populations in the wild at locations
they don't occur at naturally like planting different rubra subsp all
in the same location and letting them go wild - Duh!
Some of these (and these are only a few examples I know of) don't
seem to be much of a problem. The Sarr hybrids in PA are isolated in
a glacial ditch with nowhere to go. Other locations will be developed
and the plants killed anyway. I don't feel these are any threat.
However, the D.capensis and D.binata are really bad. I don't see a
way to get rid of them, but please don't let this stop you from trying!
I'm not sure how to feel about some of these situations. I have let
some of my S.oreophila be planted somewhere in NJ, but I have no idea
if it "took." (can't see why not, though) This was a while ago, before
I had a good understanding of the possible ramifactions.
Some people are adamant that there is good to be had and these can
increase the biodiversity while others are just as critical of such
events and veiws. So I pose this question: If plants that fill a very
similar ecological nitch, and are not invasive (like Sarracenia and NA
Drosera), to some of the native species are introduced into a area will
harm be done? I almost always see D.rotundifolia, D.intermedia and D.
filiformis growing near each other. Would introducing VFT to such an
area really cause harm? I don't know that there would be any species,
CP or not, that would be threatened by it's presence as it has it's own
nitch (close, but not the same to those of the Sundews present).
Down south, many Sarracenia grow together, while in NJ it's only
_S.purpurea_. What harm could be done by sowing seed of another species
where S.purpurea is present (on private land, of course!)??? I can't
come up with a solid argument against it. (please don't say you can't
say what harm's possible until the harm is done - I know, but I just
don't see it in some cases)
I know we covered this resently, but most of the bad examples I recall
like those vines covering up the Southeastern states were cleary
invasive weeds in the first place (they were used *because* they cover
everything). So please use examples where the threat wasn't so clear
in the first place.
Thanks,
Dave Evans
