We humans also are culprits in spreading the seed via our own disturbance. In Northern Virginia, I have seen dense stiltgrass stands in fairly shady areas, so I am not convinced that shading makes that much difference. although surely it helps. Any way you look at it, the deer contribute to the problem. Cheers,<BR>

I wish we could get the Crummies Creek virus or blight to infest our stilt grass populations in south central PA and central MD.<BR>

<BR>
Deer browse the natives, which has left the forests of central NJ without a sapling, shrub, and herb layer. More light reaches the forest floor.<BR>
<BR>
In healthy forests, with less deer pressure, there native plants below the canopy level. These plants create a level of shade that significantly reduces or eliminates the presence of stiltgrass. <BR>
<BR>
I've observed this to be true in upland, mesic, and lowland forests. <BR>
<BR>
I'd been interested if anyone else has observed the stiltgrass-free ring that occurs beneath a robust shrub or sapling.<BR>
<BR>
Deer management is a great tool in invasive species control, right next to herbicide. <BR>

wow. Send some of your deer down our way....ours aren't eating the stiltgrass at all. And it's flourishing in full shade. Maybe that's just because it's so much hotter down here?<BR>

In forest habitats, Stiltgrass is usually controlled by shade cast by native seedlings, shrubs and small trees, as well as herbs and grasses. Most of these forms of plant life are browsed excessively, however...<BR>
<BR>
In deer exclosures, jewelweed is a great control method. Is deer management an option on the preserve and adjacent parcels?<BR>
<BR>
On a very limited basis, I have smothered the seeds with oak leaves removed from my driveway. I placed the leaves in a forest exclosure beneath a red maple canopy. This is feasible in garden-like situations.<BR>

I notice you did mention herbicides. Research has shown effectiveness of crabgrass pre-emergent herbicides on stiltgrass and, if the site warrants it, you can also kill stiltgrass with post emergent selective grass herbicides such as Poast and Fusilaide. Of course, depending on your state law and the material selected there may be a requirement to have the application done by a certified pesticide applicator.<BR>

Deer may be more effective in bringing in stiltgrass since the areas contiguous with Swann Park are now covered with stiltgrass so it is easier to come in. So stiltgrass is probably moving in by deer and water from abundant sources from outside of the park. <BR>
