I don't know which native species Fred was referring to, but far greater
hazard to the whole ecosystem can derive from the introduction of
<b><i>non-native </i></b>species into wetland or any other
habitats. I would suggest you do a lot of reading and talking
before you even consider introducing non-native plants into this or any
other application.<br><br>
Non-native problem plants in wetlands include water hyacinth, purple
loosestrife, and many others.<br><br>

<blockquote type=cite class=cite cite="">I have worked with the process
you speak of quite a bit at times. In fact I use natural vegetation to
biofilter our aquaculture sites. Probably the easiest and most dependable
plant you can use for this is the cattail. They are commonly used on mine
sites now because they are so good at binding many substances. Bog plants
in general are very good at this. as they burn up bicarbonates when the
sun shines they collect metals in their root systems. Yellow Flag(
japanesenaturalized) or blue flag native but not much different are also
good. Some of the most problematic plants as far as growing over the
entire waterway are the native ones. Stay away from anything viny. Lotus
and lilly are good but need to be tamed now and then. If you are dealing
with a sewage treatment system bullfrog tadpoles are good for controling
bacteria but you need large numbers. Fred Hays<br><br>

Subject: [PCA] native plants for cities, stormwater management<br>
Date: Tue, 07 Dec 2004 11:53:47 -0500<br><br>
I'm looking for information about native plants adapted to various kinds
of stressful environments, particularly salt and heavy metals. It's
my firm belief that plants can take care of soil and water better than
facilities made of concrete and other man-made materials. And I
prefer to use native plants, because they are unlikely to turn out to be
invasive, and because they are more likely than exotics to form
collaborative relationships with soil organisms and above-ground
wildlife.<br><br>
I'm currently working on a grad school project to design a landscape for
a vacant lot which will divert stormwater from the street into the lot to
be filtered and slowed down. Most vacant lots previously had
buildings on them, which means they now have fill dirt, and infiltration
facilities are not permitted on fill. So the water has to be
returned to the storm drain system, but some will evaporate and the rest
will be returned slowly, reducing the volume of fast-flowing water during
the storm.<br><br>
The man at Baltimore's Dept. of Public Works who issues permits for this
kind of thing says a solution would be very valuable, and could be used
on many vacant lots throughout the city. If I can get this to work,
it could have a very significant impact. Did you know that much of
Baltimore's stormwater is piped directly into the Inner Harbor? And
it carries cadmium, copper, chromium, lead, and other heavy metals,
mostly from tires, some from diesel exhaust, and some from old lead
paint. And road salt, in winter.<br><br>
If you have seen plants either survive or be harmed by road salt, air
pollution (e.g. from bus exhaust at a bus stop), or heavy metals (e.g.,
lead paint chips in the soil), I'd like to know about it.<br><br>
Also, if you know of published information please tell me. I have
Dirr's Manual of Woody Landscape Plants, which has this kind of
information for many trees and shrubs. Is there something
comparable for herbaceous plants? I also have Md. Dept. of
Environment's Stormwater Design Manual, which has a long list of plants,
indicating tolerance to salt and pollution. The only plant listed
as tolerant to both is Eastern white pine. Most likely this is a
list of known tolerance, i.e., no check mark means no knowledge, not no
tolerance.<br><br>
Your help will be much appreciated.<br><br>
