'californiaweedtalk@topica.com'<BR>Subject: [APWG] Removing invasive
grasses<BR><BR>Does anyone have any suggestions on an approach for removing
invasive grasses that are inter-mixed with wetland vegetation such as rushes,
sedges and native salt grass? The grasses we are dealing with are veldt grass
(Ehrharta calycina) and velvet grass (Holcus lanatus) primarily. We have a real
problem and we're not winning the battle by hand digging. There's too much of a
seed bank and the soil disturbance just brings up a whole new crop. I'm thinking
of perhaps "sacrificing" a section at a time and just spraying everything and
replanting wetland vegetation. I would try to hold the line against any new
invaders and move to a new section when things were pretty well established. It
might be easier to control new grass shoots.<BR>But I recoil at the
thought of killing that many native plants. Are there any selective herbicides
(or concentrations) that would set the grasses back, but not do in the sedges
and rushes? Any other mechanical methods - mulches, weed barriers, flamers,
whatever that anyone has used with any success?
