<p class=MsoNormal><b><font size=3 color=navy face="Times New Roman"><span
style='font-size:12.0pt;color:navy;font-weight:bold'>I am excited about your removal
of <em><i><font face="Times New Roman"><span style='font-style:normal'>Akebia</span></font></i></em>
at Monticello. Perhaps you could leave the smaller amount of periwinkle that was
there historically and remove the rest that would not be historically accurate.
It took 114 volunteer hours to eradicate a one acre patch at <st1:place w:st="on"><st1:PlaceName
w:st="on">Swann</st1:PlaceName> <st1:PlaceType w:st="on">Park</st1:PlaceType></st1:place>
so 40-50 acres would take about 20 people a day for 40-50 days. If you back
pack spray, the Jack in the pulpit, false soloman's seal, black cohosh, <em><i><font
face="Times New Roman"><span style='font-style:normal'>Stellaria pubera</span></font></i></em>,
<em><i><font face="Times New Roman"><span style='font-style:normal'>Geranium
maculatum,</span></font></i></em> that seem to coexist with the Vinca in this
area would have to be carefully avoided. What was the colonial density of deer?
Could you justify deer control for historic as well as natural heritage
reasons? Cheers. <o:p></o:p></span></font></b></p>

<p class=MsoNormal><b><font size=3 color=navy face="Times New Roman"><span
style='font-size:12.0pt;color:navy;font-weight:bold'>Thanks for your
interesting suggestion that we wipe out the naturalized <em><i><font
face="Times New Roman"><span style='font-style:normal'>Vinca minor</span></font></i></em>
in the woods along the cemetery/Shuttle Station Trail. I realize periwinkle is
an exotic invasive, and it has smothered native populations of plants in this
area, just in the 30 years I've been here at <st1:State w:st="on"><st1:place
w:st="on">Monticello</st1:place></st1:State>. On the other hand, in 1771,
Jefferson himself (<em><i><font face="Times New Roman"><span style='font-style:
normal'>Thomas Jefferson's Garden Book</span></font></i></em>, Betts, ed, pp.
24, 27) recorded the desirability of planting "Periwinkle" as a
"hardy perennial flower" or naturalizing ground cover in this very
western side of <st1:State w:st="on"><st1:place w:st="on">Monticello</st1:place></st1:State>
mountain. In addition, and this is an aesthetic judgement, I find periwinkle
one of the least offensive of the exotic invasives that plague us. It's a tidy
plant that doesn't spread as fast as the other horrors we deal with in our
forests: wineberry, <em><i><font face="Times New Roman"><span style='font-style:
normal'>Akebia</span></font></i></em>, Japanese stilt grass, Japanese
honeysuckle, privet, Russian olive. We've recently led a campaign to wipe
out acres of <em><i><font face="Times New Roman"><span style='font-style:
normal'>Akebia</span></font></i></em> from an old forest on the south side of
the mountain, and I'm very much on the watch for a few plants that are spring
up around the cemetery. Finally, some highly desirable native herbaceous plants
-- Jack in the pulpit, false soloman's seal, black cohosh, <em><i><font
face="Times New Roman"><span style='font-style:normal'>Stellaria pubera</span></font></i></em>,
even <em><i><font face="Times New Roman"><span style='font-style:normal'>Geranium
maculatum,</span></font></i></em> and others<em><i><font face="Times New Roman"><span
style='font-style:normal'> -- </span></font></i></em>seem to coexist with
the Vinca in this area. Finally, we really don't have the guns (time, labor,
money, staff) to do something like that -- we probably have 40 - 50 acres of
naturalized periwinkle at <st1:State w:st="on"><st1:place w:st="on">Monticello</st1:place></st1:State>.</span><o:p></o:p></font></b></p>

<div>
<p class=MsoNormal><b><font size=3 color=navy face="Times New Roman"><span
style='font-size:12.0pt;color:navy;font-weight:bold'>Anyway, I agree with you.
I'd prefer to have a pure stand of indigenous plants here at <st1:State w:st="on"><st1:place
w:st="on">Monticello</st1:place></st1:State>, but you also need to carefully
choose your battle. Pure forests, at least those visited by
humans, are becoming a thing of the past. It's my opinion that it'll get
worse every year -- that Japanese stilt grass and white
tail deer disruption are impossible to thwart except in small, discrete,
fenced in, heavily monitored and maintained areas. It may have been
someone associated with your forest, or near you, that I heard speak
about the effect of exotic earthworms eliminating the leaf litter on forest
floors, thereby changing the constituency of the native ground cover. Talk
about scary stuff.</span><o:p></o:p></font></b></p>
