<p class="MsoNormal">It is spreading fast along the Rivanna River here in Albemarle County and is pretty much done blooming and will shortly disappear from the landscape until next year. It is definitely spreading through a private property with 1-2 miles of
river bank. We are more or less at 600' in elevation here. It has also spread along the riverbank at a park in the city of Charlottesville, And I was at a site behind VMI in Lexington, down along the Maury River and it has taken over there. I don't know how
extensive the area with this plant is, but it's rather pitiful: Bluebells poking up through the C incisa along this stretch, which is (or was?) very rich. Sigh.<o:p></o:p></p>

<p style="margin:0in">We have a 30-acre area on the Difficult Run Stream Valley in Fairfax County of Corydalis incisa. For that area, we are just trying to contain and keep it from spreading further out from center. However, it’s been located all along the

<p style="margin:0in">If you’re like me, you have not been aware of the rapid growth of incised fumewort in the past few years. Under Sara Tangren’s leadership the Nat Cap PRISM started tracking it this spring with our network of Invader Detectives.
<o:p></o:p></p>
<p style="margin:0in">It’s…everywhere, and it appears to be outcompeting or outright killing bluebells wherever they occur together. USDA’s weed risk assessment for this species found no evidence for allelopathy in field tests, but that had high uncertainty.<o:p></o:p></p>
<p style="margin:0in">Please click on the iNatualist entry below and look at the images. It appears to occupy 1+ acres in Seneca Creek State Park in Montgomery County. This is the largest population that we have found this year, but it appears to go from
a few plants to a large population in only two or three seasons.<o:p></o:p></p>

<p style="margin:0in">Hi All, <o:p></o:p></p>
<div>
<p style="margin:0in">I’ve spent the last week helping combat an infestation at Hemlock Overlook Park (Bull Run watershed, VA). The appearance of what is going on there suggests that the plants are allelopathic, but only scientific tests could tell us for sure.
To see the bluebells, violets, and spring beauties being overrun was heartbreaking. It took only 3 years to go from first observation to serious ecological damage and first response. We’ve got to react to this species more quickly from here on out.<o:p></o:p></p>
</div>
<div>
<p style="margin:0in">Today I’m catching up on iNat reviews and came across this one by our own esummerbell. Her photos do an excellent job of capturing just how bad incised fumewort can get, please have a look. <o:p></o:p></p>
