Weather conditions caused me to temporarily suspend cedar
maintenance work on the Middle Field, but conditions have taken a favorable
turn and my work has resumed. Marking
flags were left in place during the poor weather and except for a couple of
flags that suffered at the hands, or I should say mouths, of the deer,
everything was as I had left it. I began
my work at the wide end of the field, so each move forward is a little narrower
than the one behind. It didn’t take long
to finish off the two acre field.
Many of the removed cedars were quite short, making my after
photos look not much different than the before.
I probably see more in the after photo than most people, because I can
still remember the look of each bit of ground as I zigzagged my way across the
field looking for tiny cedars.
Small oaks are growing well next to the ant mounds in the
field. The oaks have gotten large enough
to host a batch of Edwards’ Hairstreak larvae.
The butterfly has already established a colony in the next field
over. I’m hopeful that in the next year
or two I’ll also find the butterflies in this field.
Virginia Pine seedlings are almost as numerous as cedars in
this field. Despite the fact that deer
give these trees a good yearly thrashing, some have managed to survive and are
threatening to grow to seed bearing size.
I decided to go ahead and cut all pines not growing in the designated
Pine Grove area.
I’ve been trying to remember to take more before and after
shots of my work efforts. I think they
have value in illustrating how different types of management techniques change
a particular area; even if it’s just the removal of a single tree. In this case I failed to notice that I hadn’t
moved the cut tree completely out of the frame. That’s it on the left side just beyond the
small ant mound. I had taken the before
shot earlier in the afternoon, but didn’t cut the tree until evening. After hurrying to cut the tree so I could
take my after shot before it got too dark, I drug it down and left it beside
the brush pile that is to the left just outside the photo. I was so busy lining up features to make the
after shot match the before that I never even thought of the tree laying there
in front of me.
Several orange ribbons mark plants that either need to be
cut and sprayed this coming spring or need to be protected from the mower. Most are roses. About half are natives and the other half are
multiflora.
I found two Chinese Mantis egg cases in this field. The female mantis lays two or three masses of
eggs, usually in close proximity to each other and covers each mass with a
foamy mixture that hardens into a protective case. When an egg case is found, a quick search of
the immediate area should turn up one or two more. The Chinese Mantis is an introduced species
and is a predator famous for its ability to capture and consume large
quantities of insects. I don’t
appreciate exotic predators threatening the native insects, so I do what I can
to reduce the size of the Chinese Mantis population.
This is the egg breaker treatment I give to each egg
case. The elongated eggs are situated
inside the case in such a way that a cut with my hand pruners from top to
bottom through the case destroys the entire batch. Several years ago, I could easily find many
dozens of egg cases in these fields.
This year, I have found only six egg cases over an area of 25
acres. My efforts must be having an
effect.
I took my search for small cedars right though the old fence
row and to the edge of the next field.
Since the removal of the last of the non-native shrubs, the fence row is
looking quite open. I’m anxious to see
what plants may appear here now that sunlight can reach the ground.
Snow load and wind put this Virginia Pine into a permanent
lean. If left in this position, it would
kill the grass beneath its dense branches.
I chose to remove it.
This time I managed to get the tree out of the way for the
after photo. In its upright position,
the tree did not cast a dense enough shadow to adversely influence the growth
of surrounding grass. I certainly didn’t
want to lose this nice patch of prairie grass to a reclining pine.
If the weather cooperates, I’ll bring JR out in a couple of
days and mow this field. The primary
targets for the mowing are some clumps of blackberries and sumacs. Mowing will also allow me to more easily
evaluate the early spring growth and identify any potential future problems.
