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 style='mso-special-character:line-break'>

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.</span></font><font color=black><span style='color:black;mso-color-alt:

<p class=MsoNormal style='margin-right:1.5in;mso-margin-top-alt:auto;

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>
