[MAIPC] Japanese Stilt grass at Catoctin

Sat Dec 22 05:04:18 PST 2018

Hi Bill,

Can you follow up on about how much Japanese Stiltgrass has declined at
Catoctin Mountain National Park with deer now reduced to 15 or 20/square
mile? I remember that you have good contacts there. Dick Reardon is still
looking for JSG biological controls in Eurasia. Deer exclosures reduce JSG
to easy controllable densities. The question has been if natural densities
of 20/square mile work well. Mark Frey has told me about this success at
Catoctin at our invasive species control conference last week in Nashville.

Hi Mark,

As we discussed in Nashville, could you send me some statistics on the
reduction of JSG at Catoctin Mountain National Park with deer reduced to 15
or 20/square mile. We know exclosures work well but who can afford
exclosures? Besides we need some deer. Thanks 

Marc

Hi Natural Places Committee and Outings committee working groups,

Here is an example of a white tailed deer hunting program conducted
primarily to protect visitors from Lyme Disease from Deer ticks as well as
restoring our native ecosystem. When this program reaches the goal of 20
deer /square mile we will add this place to the list of better places to
hike during tick season.  The following list I hope you can help update for
your county.

Subject: 12/1 Scout Day at QABR CWMA

FYI

We had our first scout day for QABR CWMA this afternoon from 12pm to 4pm. A
total of 17 hunters went to the site to scout the area inspite of the rain.
Folks were excited about the new hunting opportunity and were very
appreciative that we are opening a public hunting site.

Recreational hunting is another side of our deer management program. We plan
on adding more sites in the future.

We will have another staffed scout day tomorrow, 12/2 from 8am to 2pm. Queen
Anne Bridge Road CWMA will be open to public bowhunting starting Monday,
12/3. The site will operate from Monday to Friday. Hunters are allowed on
the property 1.5 hours before sunrise and 1.5 hours after sunset. Legal
shooting hours are half hour before sunrise and half hour after sunset.

The following list I hope you can help update.

Many studies have shown that when deer are present at 20/square mile or
less, there is a dramatic reduction in the cases of Lyme disease. Here are
some parks with this lower deer density of 20/square mile as a result of
managed hunts and exclosures. 

Howard County

 <https://www.howardcountymd.gov/MPEA> Middle Patuxent Environmental area 

 <https://www.howardcountymd.gov/MeadowbrookPark> Meadowbrook Park

 <https://www.howardcountymd.gov/SchooleyMillPark> Schooley Mill Park

 <https://www.howardcountymd.gov/WesternRegionalPark> Western Regional Park

 <https://www.nps.gov/rocr/index.htm> Rock Creek National Park in Washington
D.C. adjacent to Montgomery County

 <https://www.nps.gov/cato/index.htm> Catoctin Mountain National Park in
Frederick County

ANS Woodend Sanctuary in Prince George's County

Piscataway National Park in Prince George's County

All of these areas have a natural deer density of 20/square mile or less.
What makes this number significant is that this is the level that deer
existed at before the removal of predators such as wolves and cougars. Many
studies have shown that when deer are held at this level there is a dramatic
reduction in the cases of Lyme disease. 

If you wish to lead hikes in areas other than those listed above that do not
have control of deer ticks, it is recommend that you wait until mid-July
through mid-April when the seasonal risk of Lyme disease is less. We would
also greatly appreciate it if you could work with us and your local parks as
we continue to spread awareness on the severe issue of Lyme's disease and
its connection to overpopulation of deer. The period of time when deer tick
season is the worst. usually extends from mid-April until mid-July and can
put quite the damper on outdoor activities. To avoid the risk of contracting
Lyme disease we recommend that you lead hikes in areas with good deer
control. 

Thanks, 

Marc Imlay, Natural Places Committee Chair
