Interesting observations in the field and forest - during late afternoon
walkabout.
1) Control of invasive Bermuda Grass is possible using interplanting
or overseeding of lespedeza, maybe sericea lespedeza, a perennial:
"Sericea lespedeza spreads primarily by seeds. The method of seed
dispersal is probably by animals." (wind or runoff).
This is a wonderful plant. It can take over a field as it provides
fertility through fixation of atmospheric nitrogen. It will outcompete
many plants that become problems for farmers or gardeners, i.e. Johnson
grass, Bermuda grass, redroot pigweed, winter ryegrass, fescue grass,
crabgrass and many other "weeds" (compostable). It has done this for me
in a large field I have left fallow and I am grateful for it. I think I
have it from a deliberate planting I made a long time ago. I bought a
bag of sericea lespedeza and spread it over about .5 acre. It is
extremely hardy resisting cold, heat, prolonged rainfall and drought.
It will thrive in poor, dry, compacted, unfertilized soil where you
often find Bermuda growing. I am watching an unwanted patch of Bermuda
disappear within an ever spreading stand of Lespedeza.
2) As I was looking at the new lespedeza sprouts I noticed a large,
spreading spider web nearby, spanning the entire forest opening into a
small glade. It was some unidentified harmless brown spider, lovely to
look at. I focused my flashlight on bright beam on the web and saw the
spider very busily walking around the web. I then noticed that it was in
the act of spinning the web itself. I have never seen this before.
It seems that, after connecting the long strands attached to nearby
branches all to a central point in the web, have laid a coarse series of
concentric spirals out to the web edges then, as I watched, started
inward, filling in the gaps with more rings in a more closely spaced
pattern. It was also interesting to note that the very central thee
inches of the web were made of thinner silk laid in very closely spaced
rings. It seemed to be a part of the web specially designed to attract
and catch prey as it had a small glob of white silk at the center of
this highly flexible section which, with the slightest wind or
vibration, would wobble in and out and vibrate, possibly looking like an
insect to some other unsuspecting predator. This section was so soft and
flexible that anything touching it would become immediately ensnared to
provide food for the host.
3) Flashlight:
(I have one of these and would not be without it - cheaper knockoffs are
a waste of money, Surefires always work when needed - a must have for
waling at night during poisonous snake season (now and until mid to late
October for me). Play it safe and never be wothout a good flashlight
when walking outside at night, and the brighter the better.

Description
6PX-B-BK
The 6PX Pro's high-efficiency LED—virtually immune to failure since
there's no filament to burn out or break—provides two light output
levels: a brilliant, penetrating, perfectly pre-focused 200-lumen beam,
and a 15-lumen low-output setting that lets you greatly extend the
runtime per set of batteries, an invaluable option when you find
yourself miles from civilization. Press the tailcap switch for
momentary-on low, press further to click constant-on low, return to off
and press or click on again within two seconds for high. The
high-strength aerospace aluminum body is smoothly sculpted for a
comfortable, secure grip and is hard anodized to military specifications
for extreme resistance to scratches, abrasion, and corrosion. A
polycarbonate micro-textured reflector delivers a comparatively wider
beam with generous peripheral light. We also make a polymer-body version
of this light, the G2X Pro, and a single-output version with a tactical
tailcap switch, the 6PX Tactical.
