Is MNDNR's role on invasive species just information and enforcement?

Have you read the recent article about a new invasive species that threatens Minnesota's forests? ("University of Minnesota botanist discovers feared invasive Japanese stiltgrass in Wisconsin") It appeared shortly after I took some pictures of nearby wild cucumber and Joe Pye weed and some other local wild flowers. On the way home, I noticed some purple / lavender streaks in the rushes along the Sunrise River in Carlos Avery Wildlife Management Area South  of County Road 36. I fear the streaks may be made by sizable stands of purple loosestrife.

is that a purple loosestrife stripe?

I've noticed over the course of a number of internet searches, that the Minnesota Department of Natural Resources [MnDNR] provides lots of information to Minnesotans to help us manage invasive species, but I've yet to find a description of their own invasive species management programs for state parks, wildlife management areas and similar public properties for which DNR is responsible. And yet, since we live at the edge of a large wildlife management area, and near several state parks and Scientific and Natural Areas, we frequently see stands of buckthorn and loosestrife(?). According to one of DNR's web pages

Common buckthorn and glossy are listed as Restricted noxious weeds (link is external) in Minnesota. It is illegal to import, sell, or transport buckthorn in Minnesota.

But, apparently, there is no requirement to eradicate it although a number of responsible conservation organizations do organize buckthorn removal activities.

Perhaps it's just me but I find it more than mildly annoying and hypocritical that DNR' s aquatic invasive species [AIS] program is focused on enforcement of the prohibition of transporting such species, but DNR does not seem to feel obligated to remove AIS, or terrestrial invasive species, from their own properties. As long as major reservoirs of invasive species exist in Minnesota, we'll constantly be playing catch up and our efforts to manage invasive species are likely to be further hindered by the effects of climate breakdown.

Japanese Knotweed Killers 

By Jan Wrede

We smote and killed.

No broken needle.

Some chemical remains.

Needle too large for small stalks.

Injector refill problematic.

 

Victim mortally wounded.

Time for mercy

And finishing spray?

When is the coup de gras?

Killers are ready
