I recently watched a program on TV about control of cattails growing in =
marsh land. In this case they stressed the importance of removing the =
rhizomes completely if you were to eliminate them, because of the abilty =
of the aerenchyma cells in both the living and dead leaves to supply =
oxygen to the submerged rhizome. The program particulary interested me =
at the time as I had a problem with wild Iris and bulrushes in my small =
lake and also in the wetland flushes in my woodland.
Regards,
David

<DIV><FONT face=3DArial size=3D2>Thanks for your comments which are =

</FONT></DIV>
<DIV><FONT face=3DArial size=3D2></FONT> </DIV>
<DIV><FONT face=3DArial size=3D2>However, I was specifically addressing =

question about the potential "crop" that he has access to and assuming =

would not want to eliminate them entirely in order to maintain =

supply and also he did mention that they provided a benefit by filtering =
polutants in this particular environment. I also pressumed as =
Daniel had=20
copied your post to this list that his potential use for them would =
be as=20
biomass for gassification, In which case I was suggesting that he would=20
only need to harvest the tops especially when they were dying, =
which would=20
make drying easier, thus my tongue-in-cheek reference to coppicing,=20
</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=3DArial size=3D2>From what Daniel said about using a =

and also about pulling them up by the roots and washing off soil, it was =
clear=20
that the cattails to which he refered were not floating. Having said =

thank you for bringing this to my attention.</FONT></DIV>
