2.5 acres reduced to 0.5 acres, Japanese stilt grass 3 acres reduced

Honeysuckle, 10 acres, the vertical component up the trees was
entirely removed by 2000 and half of the horizontal component is removed
because it is no longer served by light reaching the verticle
component. 25% of the remaining horizontal component was
removed.</STRONG></FONT></FONT></P>
<P align=left><FONT size=2><FONT size=3 face=Arial><STRONG>About half was
removed mechanically with an average of 5 volunteers working once
a month for about 10 years and half treated chemically.

about 10% of the herbaceous and shrub cover was non-native as well as cover by
two tree species. It is now about 2% </STRONG></FONT></FONT><FONT

Native grassland and forest understory weedings 99%<BR><BR>Dear Marc and
All,<BR><BR>The remarkable other side to Mark Vande Pol's weeding, is everywhere
that was covered with weeds, is now covered by local native plants in the
grasslands and forest understory.<BR><BR>I am pleased to hear that you joined
the 99% club at Swann park in<BR>Maryland-- so how many people over how much
time, did it take to do how many acres, with what weeds were you dealing with,
and have you ever written up your experience anywhere?<BR><BR>Any others who
belong to the 99% club out there?<BR><BR>Sincerely, Craig Dremann (650)
