General
Stuff
This past month
has been a flurry of activity. With the Director's visit and other
happenings, it seems as though it is hard to stay on track. The
summer work is going well and with so much happening, we are presenting
only a sampling of what is taking place.
Biological
Sciences - Wildlife
Northern goshawks
(Accipiter gentilis) have taken up residence within
the park for the second documented time. The nest site was reported
by the cavity nesting researchers and verified by Duane Weber.
These forest hawks are aggressive killers and can take birds
as large as pheasant and readily take rabbits. Goshawks usually
mate for life and return to nesting area year after year. Goshawks
are expert fliers, weaving through forest areas at top speed.
They are truly magnificent birds, but don't turn your back on
them!
Physical
Sciences - Cave and Karst
The Cave and
Karst Inventory Project has been in full swing for just over
a month. During this time, Seth Spoelman and Jason Walz, the
first
ever seasonal ridgewalking crew, have walked more than 80 miles
systematically searching nearly 1200 acres of the park for unidentified
cave and karst resources. Their efforts, along with the help
of several volunteers, have added five new caves, seven new rock
shelters, and 51 new karst features to Wind Cave's cave and karst
inventory database. The new data has been integrated with several
pre-existing documents, allowing the entire inventory to be mapped
and manipulated within the park's GIS.
Seth and Jason
have photographed, written physical descriptions, obtained geographic
coordinates, and performed a brief geological, biological, and
cultural inventory for each site found. When a site has qualified
as a cave (i.e., it is more than 15 feet long) or a rock shelter
(i.e., an overhang or solutional feature that is wider than it
is deep and capable of providing shelter for humans or animals),
it has been carefully surveyed and mapped using a compass, clinometer,
and laser range finder.
Some highlights
of recent discoveries include some potentially significant cultural
artifacts and evidence indicating that a variety of wildlife
use the park's cave and karst features, in particular for shelter.
Porcupine scat and woodrat (packrat) middens are extremely common
and other cave and karst features inhabitants include bats, insects,
rock doves, and prairie falcons. One new cave was found to be
inhabited by a baby turkey vulture! The same cave also contains
what appears to be an old moonshine still. Further investigation
has been delayed due to the presence of the vulture. Graffiti
and digging marks found in a rock helter named "Stacked
Shack" may also be of cultural significance.
Resource
Data Management
A number of
people have inquired about the online training available through
the ESRI Virtual Campus. This opportunity came about through
an agreement between the Park Service and ESRI (makers of the
software). As a reminder to anyone who is interested in learning
about Geographical Information Systems (GIS), you can enroll
for an online class to access a number of courses by visiting
this website: http://data2.itc.ns.gov/gis/esri/vc.cfm.
In order to
sign up you'll need to use a computer here at the park and have
a Lotus Notes account (if you do not, ask your supervisor). The
classes are self paced, most have six modules that require about
3 hours each and you have one year to complete the course before
it expires. Plus, there is no cost to you which the agreement
is in place. All in all this is a good deal. A recommended starting
point would be to sign up for "Learning Arc GIS 8, Part
I". The
software, Arc View 8, can be installed across the network on
any machine so you do not need CD's. If you have any questions
stop by the resource shop.
Some of you
noticed that the GIS server was running a bit slow a few weeks
ago. This was because of a few issues with the backup
hard disk. The problem has been resolved and we're back up and
running at 100%.
