[MAIPC] Fall Conference

Mon Jul 16 04:51:24 PDT 2018

Here are some questions for discussion at the invasive species fall conference sponsored by the Maryland Native Plant Society at UMBC. Please bring your discussion items especially for the social. https://mdflora.org/event-2881501 THE TIMES THEY ARE A’CHANGIN’: THREATS TO MARYLAND’S NATIVE PLANT COMMUNITIES (2018 MNPS FALL CONFERENCE) September 15-16, 2018.

1. How well have we looked over the entire range of each invasive species for a native biological control to pop up as happened for Multiflora rose and tree of heaven?

2. You think Stink bugs are bad. Then came Spotted Lantern Fly. Can we partner with Agriculture and health advocates (and Trump, Ha, ha.) to better prevent immigration of new invasive species?  The worst is yet to come. 

3. How well do deer eat up the Japanese honeysuckle when the deer density is at a natural density of 20/square mile versus in exclosures?

4. Have studies been done on preventing about half of the trees from falling down over highways during a major storm for about 10% of the effort to control them all. It just takes 10 minutes to cut stump the non-native invasive vine, such as oriental bittersweet, English Ivy and Japanese Honeysuckle, at ground level. Trees came down over electric power lines causing the electric power outage and subsequent brush fires. Did the studies indicate how much $ was saved for mitigation costs after a storm? 

5. Can we focus on natural areas that have almost no deer because of difficult habitat for deer to climb up and down such as Shepherds Spring described below, and Pembroke Mountain Lake. I had in mind the value of the land for Program Open Space and conservation easements as well as funding for invasive plant removal to protect the endangered species. 

6. Why has rose rosette disease significantly impacted Multiflora Rose in several of my parks but has not come back?

7. Has anyone surveyed native American bittersweet, Celastrus scandens where it is not yet near oriental bittersweet, Celastrus orbiculatus, for potential insect or pathogen biological controls of oriental bittersweet? They are very closely related and may by hybridizing.  <https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.co.becker.mn.us%2Fdept%2Fsoil_water%2FPDFs%2Fweeds%2FOriental_Bittersweet.pdf&data=02%7C01%7C%7C09c17a7654fa4f47e7df08d5df68c2ac%7Ca9061e0c24ca4c1cbeff039bb8c05816%7C0%7C0%7C636660563418712020&sdata=pbFCyVFSGRA9xujIdlMNoQQMA4CBV6hl7yEYt7mnFvo%3D&reserved=0> http://www.co.becker.mn.us/dept/soil_water/PDFs/weeds/Oriental_Bittersweet.pdf

8. Why has Bipolaris rust hit Japanese Stilt grass in several places in my parks but not come back in subsequent years (except for one place)?

9. Does it ever make sense to bring the Kudzu bug to some Kudzu near a patch of wisteria needing control if no soy bean crops are nearby?

10. Any updates on biological controls such as for Japanese Knotweed, Fig buttercup,  garlic mustard and WLBG?

11. Is the reduction to 20 deer/square mile effect on Japanese Stilt grass comparable to the effect of deer exclosures? Managed hunts are possible when deer enclosures are not. 

12. If an invasive plant species is having 100 times the impact on endangered species as a potential biological control is found to have, should we modify the regulations? (is the bug candidate for JSG somewhat like this?).

Dear Marc,

Thanks again for the information below!  I have forwarded it to our State DNR representative for use in helping to determine the value of the land as part of the Program Open Space project.  

You mentioned that we may be able to seek grants for the endangered ferns.  I did a quick Google search last week but was unable to see how to get started with that.  Would you please advise?

Take care,

Dotty

Hi everyone, 

Following are the critters we saw on the nature walks and the participants. The finding of the endangered glade fern can help generate grants for this park. Non-native Invasive species are in the relative early stage and removable. This park is high in biological diversity. Thanks all.

Marc

Hi Marc and Mike,

In case they might be useful for planning the nature walks at the Jamboree, I have posted some observations of things we saw yesterday on iNaturalist at https://www.inaturalist.org/observations/jgingold
