Observations from the past month of days....
Jennifer and Steve at
Glennwood 2/2: We walked back into the preserve
via an easement/old lane. To our right was a cutbank where we
noticed groundhog excavations and red, sandy soil mounded around
them. This red, sandy, well drained soil provides a much drier home
to burrowing critters than the other soils here. We also noticed
scat with large bone fragments and concluded that it must have
been coyote scat. A couple of trails head off to the west and
toward the bog and the lane ends with a short loop trail amongst
upland hardwood forest of oak and hickory. It's great that this
upland forest is protected as it provides a nice contrast to the
wooded wetland and bog communities. We headed down toward the bog
via the wooded wetland. The next trail headed downhill and toward
the bog and took us by
lycopodium spp. moss and
cinquefoil spp. We took a moment to appreciate the "floating" nature of the bog and then followed the trail around the east side
of the bog and through the swampy forest.

It's apparent from
the
many toppled trees that shallow-rooted trees are about as tipsy
as SUV's!! Toppled trees, also know as windthrows, create "knolls"
and "cradles" where conditions are a little bit dryer and a little
bit wetter, respectively, than the surrounding flat wetland
surface. These areas are worth paying attention to as they provide
extra habitat diversity and may be home to interesting species of
plants, insects, etc. Jennifer, myself, and Debby Meade visited
Glennwood in the springtime once and noticed that wood frogs were
breeding and laying eggs in the cradles - which were full of water.
So a tree falls, but a frog benefits. Here's another shot of a
windthrow. Notice how far, laterally, the roots travel out from
the base of the tree and how shallow they are. Trees generally
don't like to send roots down into a saturated soil and, thus, are
usually shallowly rooted and relatively more subject to windthrow
when growing on wetter sites. But we can use such things to our
advantage to make additional observations of natural things. At
Glennwood, it is easy to observe organic soil materials in these
"cradles" where trees were once rooted. Most organic soils form
from slowly decaying grasses and/or trees in a waterlogged
environment. Here, in this
windthrow cradle, you can see the waterlogged nature of a
typical site where organic soils form. A closer look reveals
roots and other,
finer organic materials - probably a mixture of downed trees,
leaves, grasses, sedges, shrubs, etc. Indiana's organic soils are
much more weathered (due to longer growing season, warmer summer
soil temps, etc.) than those further north, therefore, it's not easy
to identify the actual plants from which they formed. Palynologists,
though, can take cores of organic soils and reconstruct vegetative
history of a site using pollen analysis. What a fun way to make a
living!!
The trail winds
around the SE corner of the bog and then make a loop before heading
back out the main easement trail. Along this loop we found one of
the most striking examples of fluting of
Musclewood bark that we've ever seen. Our final observation was
an
unknown fungus. If anyone knows this one, please share with the
rest of us, please. Another afternoon on the nature trail yielded
more observations and sightings than we could have ever
anticipated. We are grateful for special places like Glennwood
Preserve.

Fawn
River 1/31: As I readied my gear for a hike at
Fawn River Preserve I was surprised to find another hiker pulling
into the parking lot. This preserve is pretty remote and so I was
delighted to make the acquaintance of Dick Loney of Ft. Wayne and
hike part of the trail w/him. We walked across the open old-field
then into the woods. In the woods, the main trail traverses a
pitted outwash plain. Formed by sand and gravel deposits deposited
by glacial meltwalter stream activity, a pitted outwash plain is
pretty flat and has small depressions here and there. The
depressions, I've learned, are voids left by large blocks of ice
that were entrained in the meltwater/sediment and then melted -
leaving a depressional void. I tried to get a picture to show
one of these depressions. The down and dead trees near the
center of the photo are about 10-12 feet lower than the surrounding
outwash plain flat summit. Anyone who visits here will notice these
depressions as they are obvious as well as similar to depressional
areas on the clayey till plain nearer Ft. Wayne and south. The main
difference - and it is a significant one - is that the depressions
on the clayey till plain are often ponded with water in wet time
whereas the depressions on an outwash plain are well drained. Why?
Remember - outwash plains are underlain by excessively drained sand
and gravels while till plains are underlain by compact clayey
materials. The former lets water through the latter does not. So
we would expect to find very different vegetation on in these
differently depressions. Keep your eyes out for these differences
this coming spring when the herbaceous plants start popping up!
Nearing the west
edge of the preserve, we kicked up about 6 dear and a red tailed
hawk. The hawk was feeding on a
opossum carcass. I had seen this carcass intact a few weeks ago
but now it had become a meal and part of the cycle of nature. When
I took Ornithology about 15 years ago I was taught that"raptors
won't eat carrion". Well, as Bob Dylan would say, " Times, they are
a-changin' " !!
From here, Dick and
I made the little loop down off the terrace to the Fawn River
floodplain. First we noticed some
sign of beaver across the river. Then we took photos a couple
of photos for posterity.
We parted ways here
- Dick heading back out the main trail and myself heading along the "bluff" trail. The view from atop the outwash plain summit is
sublime.
Having hiked all the
trails I headed back the way I'd come, enjoying the nice hardwood
forest, woodpeckers pecking and the knowledge that ACRES member near
and far have protected all that lives here.

Steve at
Fawn
River 1/18: This preserve near Greenfield Mills
in LaGrange County is AWESOME and deserves a visit by anyone able to
get up there. It's on the IN-MI state line, so it's a little of a
drive but it's well worth the trip. A visit to Fawn River preserve
can be combined with a stop at Rinkels Mill, which is a historic grain
mill that still grinds various flours. You can buy flour, pancake
mixes, etc. and take a tour of the mill.
Anyway, back to the
preserve. I forgot my camera so I have no photos but I'll just say
that this 138 acres preserve is so remote that, other than toll road
noise, it has a quasi-wilderness feel. The trail begins in a
recovering old-field then takes an extensive route through upland dry
woods. I say "dry woods" because this region is underlain by thick
deposits of sand and gravel - so this makes anything on "high ground"
very well drained and thus, if wooded, it will be a dry woods. The
dry woods here has mainly white oak, black oak, hickory, tulip, ash,
etc. and some fine "timber" quality trees. Thanks goodness it's now
protected from the chainsaw!
At the west end of the
preserve the trail ends up at the edge of the Fawn River. I kicked up
6 turkey and as many deer at this place and that, coupled with the
fast flowing and clear river, made me feel quite remote and peaceful.
The trails heads back the way I came but follows the floodplain. Here
the floodplain is peat soil and we all can expect some interesting
wildflowers come spring. It's interesting here because of the quick
change from very well drained sandy soil to WET boggy soils along the
river. Should make for some very interesting wandering and observing
this coming spring, summer and fall.
Fawn River preserve is
quite different from most of the preserves closer to Ft. Wayne -
mainly because of the very different soil conditions (sandy, well
drained) on the higher elevations and the more northerly (lake effect)
local climate. You can see more examples of the sort of stuff on
Pigeon River Fish and Wildlife Area but the nicer (relatively
undisturbed) areas are very hard to find. A trip to Fawn River
preserve can easily be combined w/a stop or 2 in some of the
other great ACRES preserves in LaGrange/Steuben counties.
Brad at
Wing
Haven 1/18: They say that birds can sense
incoming storm fronts based on the change in air pressure. If so,
it sure showed yesterday, as hoards of birds flocked to the Wing
Haven feeders to stock up. Among the usual chickadees, titmice, and
juncos was a lone female Purple Finch and a Brown Creeper. Two
Pileated Woodpeckers continue to search the big trees behind the
cabin in search of pupating insects.
This morning's snow created a beautiful winter wonderland landscape
outside. About two inches coated everything in sight. The
prairie struggled to hold the weight of the snow, and even human
structures like the
log barn look stunning!
Mother Nature's clean slate of snow give evidence to early morning
wanderings of some of Wing Haven's animals.
Deer made themselves known this morning while traversing the
lawn, fields, and woodlands nearby.
Steve and Jennifer at
Tel-Hy
1/12: It was the first visit for both of us and
we were treated to the splendor of beautiful weather and a grand
preserve. The
dramatic landforms at Tel-hy are a result of deep incision of the
Wabash River into the glacial till plain that dominates this
area. We left the parking lot with binoculars in hand and
strolled through weedy old-field and into a fine example of
hardwood forest. In the old-field we saw a flock of about 20 tree
sparrows presumably taking advantage of the mild weather to stock
up on additional fuel. Surely they know that winter is not
over despite the spring-like temperatures. Soon after entering
the mature forest, the trail heads down and I mean DOWN toward
the river. Geologists call this steep slope an escarpment and it
represents the erosion surface created by the river as it cut into
the till plain. In any event, its one heck of a steep trail and
provides expansive views of the river valley below. About half
way down the escarpment we noticed A LOT of bird droppings (scat)
over a large area. We concluded that it was likely a flock of
crows (a.k.a. a murder of crows) roosting in the towering tree
tops above. Not many other birds of such a large size (i.e.
that can produced so much scat) are as gregarious as crows. Once
at the base of the escarpment we noticed a small gravel bar and
ventured briefly onto it where we found
numerous remains of small fish. It appeared that these fish
became stranded in depressional areas on this bar after a flooding
event. All of the fish were partially eaten and most had the head
detached from the body. We wondered if they were fed upon by
raccoons. Mink? Raptors? Hmmmm
Also on the gravel bar, and
actually hanging out over the rushing river, was a
paper wasp nest. What could be the advantage of such a
precarious site? Surely this nest would be quite inaccessible to
predators such as raccoon.
Next we followed the trail
as it wandered along the river and enjoyed the towering tulip,
ash, sycamore and other common trees. One advantage to
appreciating common things is the increased likelihood of noticing
uncommon things. Such was the case as we came across the tallest,
straightest and largest diameter
honey locust tree that either of us has ever seen! Honey
locust is not a common canopy tree in mature forests around here.
Its more common in fencerows and other open areas. But nature
never fails to confound our attempts to keep her rigidly
classified, and thank goodness for that. We never cease to be
amazed by the beauty of lichens.
This one is a Foliose lichen. Lichens are mutualistic which
means they are the product of a symbiotic relationship of a fungus
and an algae. The fungus provides the physical structure while
the algae produces food. People who study the effects of
pollutions use lichens as indicators as they are sensitive to its
effects.
The trail then led us back
up the escarpment, onto the till plain and then followed the edge
of the bluff looking over the river valley. From here the view
was incredible in and of itself but we were further treated by the
positive sighting of a bald eagle. The large raptor soared and
circled out over the river valley and in our direct line-of-site. We wondered if this was the bird whose food scraps we have seen
down on the gravel bar.
We marveled at our luck standing in the midst of this beautiful
landscape, home to incredible forests, inhabited by soaring
eagles. And it is now protected for all time by all of us ACRES
members! What a way to end such a beautiful day! Thanks to all
who have made this experience possible.

Steve at
Culp
1/11: Culp preserve is a rare protected jewel -
rare in NW LaGrange County. I stopped by today and took a quick
hike. The warmer weather kept the birds active and I was treated to
chickadees, downy woodpeckers, hairy wood peckers, red bellied
woodpeckers, nuthatches, cardinals, blue jays, red tailed hawk and a
flock of sparrows (field sparrow or tree sparrow).
A fairly rare (in my experience) tree
occurs here at Culp. I'd appreciate verification if anyone gets up
that way soon but I think Pin Cherry grows here and there!! I'll
get some photos next time.
I've included a photo of a small tree
with an
excavation that appears to reflect that of pileated woodpecker!! Maybe someone will be lucky enough to get an actual sighting?
Culp is definitely worth a visit (and
return visits!)
Jennifer and Steve at
Little Cedar Creek 1/5: This was our first visit to
Little Cedar Creek Wildlife Sanctuary. Upon reflection, we both
feel that this place is INCREDIBLE!! Is has complex geology which
has allowed a wide variety of soils to form on distinct landforms.
Of course, this all leads to varied and interesting plant
communities!!! Here's a few things that we noted:
White patch disease (Aleurodiscus oakii) on white oak trees.
This disease causes outer bark to slough off, revealing a lighter
and smoother inner bark. The inner, living, parts of the tree are
not effected.

Steve and Jennifer at
Vandolah 1/3: Attempts at vigorous exercise
were continually thwarted (as usual!) by various interesting nature
sightings:) On the trail that runs north and south along the high
tension power line right-of-way, we noticed a grouping of conifers
among the brushy recovering old-field. Always trying to stay fresh
on our tree I.D., we approached the grouping and quickly noticed 2
quick and easy signs for
white pine:
fine, "wispy" needles and
branches arranged in
strict whorls on the trunk. Much like with attempts at tax evasion,
one thing leads to quite another, and our initial curiosity led us
to something we would have not otherwise seen. The bark of at least
one of the pine trees had been heavily assaulted by a deer's
antlers and the
soil surface at the base of the tree had been
denuded by a deer's hooves! These signs seemed pretty fresh so,
apparently, the deer are still, shall we say, "interested" in each
other!!
Shortly after the main north-south
trail enters the woods it splits. The left branch stays level, the
right branch goes downhill. Not far downhill along the right
branch, and on our right, we noticed a small tree that was bristling
with BIG thorns. You've surely seen this tree many times in the
city as it is often planted as a street tree. But don't be fooled -
this urban version is a cultivar - it has been altered to NOT have
thorns (probably a good idea for safety reasons). Anyway, the
native version of the honey locust does have thorns, as the
photo shows -lots of them - and they are long and very sharp. Probably not a good sledding hill!!
So we descended the hill and skirted
the floodplain margin and, just before we came to the place in the
trail that heads back up to the top of the bluff, we saw a HUGE
burl on a sugar maple tree! A burl, I've read, is a protrusion
or expansion on a trees trunk that is caused by atypical cell
division. Some of you may realize that woodworkers love these -
they bolt them to a lathe and turn them into beautiful bowls and
such. The interesting patterns in the woods, which arises from the
unusual cell division, make for intricate patterns in a turned
piece!!
Once back atop the bluff we took a
break and
looked out over the wetland area below. Vandolah preserves some
pretty incredible geology and plant communities!!!! The trail
follows this bluff edge through some mature forest (mainly on the
steep slope) and then heads back into brushy, recovering cropland.
We found our old friend, honey locust, again and some of its
fruit - large, flat and curling bean-like pods. These had been
apparently fed upon by some sort of rodent (squirrel maybe??).
So went another hike - full of fun,
learning and that ever-so-elusive-commodity: exercise:

Steve and Jennifer at
Fogwell Forest 1/2: Though yearning for heaps of snow,
found the dampness and warmth more indicative of spring! But nature
always has our best interests in mind.....we no more than got
started on our walk when we came upon a
regurgitated owl pellet. We made note of some of the components
of the waste from the owls' meal. Like the typical waste pellet,
it contained lots of hair and bones but also some claws. We
wondered, "mole??". Our answer was no more than 100 feet down the
trail!! We found the
severed head
and some entrails of a mouse (white footed or deer mouse)!!
Jennifer made me aware that owls may regurgitate near the kill site
so, using our powers of deduction, we concluded that the material in
the pellet was formerly attached to this mouse head!! BUT, later,
when we were home, we ruminated upon this and consulted an animal
signs authority who documents that owls normally swallow prey whole
while hawks tend to rip at them before eating. We retracted our
initial conclusion and now believe that the severed head has no
relation to the contents of the owl pellet but, rather, was evidence
of a hawk making a meal of a mouse. Either way, very interesting! We were seeing either the whole story of one meal or part of a story
of two meals!!
Animal signs are abundant this time
of year. Or maybe we just notice them more because we are not as
distracted by wildflowers and other, more showy, things of the
growing season?? Anyway, we came across a large basswood tree with
it's characteristic profusion of basal shoots. On one of the basal
shoots was a recent antler
rub. We'd expect to see fewer and fewer of these as mating
season ends and the antlers start to drop!!
Our final observation of note for this
outing was a blue ash sapling. We took a photos of a twig to
illustrate that this species has "winged" twigs and opposite branching. Because the twigs are
"winged" they appear to be square (in cross section). This is most
likely the origin of the second part of it's Latin name: "quadrangulata".
