Report on Invasives Management 2016

The good news is after a couple years of invasives management there has been a resurgence of native plants: wood aster, witch hazel, goldenrod, maple leaf viburnum, hog peanut vine, greenbrier, sassafras, beech and maple start ups, etc.

 

One complaint from dog walker - She wants the spraying sign at the entrance. She said it's too late inside preserve. But we spray only between the signs which are dated. (She couldn't find the date on the sign.)

 

I've talked to most visitors to the preserve about why we have to spray to rid the area of invasives that actually starve our birds because no insect will eat them, insects being the basis of the food chain.

 

I met a new person who told me her friend had already passed along the information. So folks who walk there are sharing the information with friends. I've talked to so many and when I'mworking on or off the trail, they wave or say hello as they pass.

 

The biggest invasive issue in the preserve is the winged euonymus shoots by the thousands. The roots are so strong that I have had to increase the percentage of herbicide as they have been growing past the area where first sprayed. We also need to address remaining full grown euonymus trees.

 

Next is Japanese barberry which is being disposed of year by year. For next year we need to designate exact boundary next to orchard so we can get as much of the barberry in that area.

 

The garlic mustard is also well entrenched and we will have to deal with a considerable seed bank. Next year we need to schedule a short Spring spraying to eliminate the flowering garlic mustard before it goes to seed. Then continue to attack the woodies, Japanese barberry, multiflora rose and winged euonymus in the Fall when it is most effective with the phloem sending mostly to the root. 

 

The program has had real success, but we can't just sit on our "laurel", we have to stay on top of the invasives or they will come back with a vengeance.
