Southern
Maryland Fishing Headwaters of the
Mattawoman 8/26/06 Mark Burchick
Fishing was cold, but botany
was hot!
After
watching some of the
Bassmaster Classic on ESPN,
with last week's fishing
tournament on the
Potomac River, and up into
the Nanjemoy, we had to go
fishing. These pro's made it
look easy, catching lunker
after lunker
on the falling tide, from
SAV grass mats, primarily
using blue-colored, soft
plastic crayfish, on
weighted worm hooks.
 |
Mark and I caught only
three bass on the day,
but had several good
strikes. I lost a big
fish in spatterdock. I
was using a senko worm
and Mark was using a
Berkley Gulp batwing
frog. |
 |
Mark and I paddled
into flooded timber
of a beaver swamp
that was dominated
by open water, mixed
with buttonbush and
occasional willow,
black gum and red
maple. Some of the
buttonbush was still
in flower, but most
were already going
to seed. |
 |
This portion of
swamp was at least
10-acres in size and
had literally tens
of thousands of
creeping
bladderwort, also
known as
two-flowered or
humped bladderwort (
Utricularia gibba,
with a synonym name
of U. biflora ).
This bladderwort is
Maryland highly
state rare (S1),
critically imperiled
in the State because
of extreme rarity.
We hit the
motherload! All of
the matted emergent
vegetation you see
in this photo is the
bladderwort in
bloom. |
 |
The plant is hard to
get a photo of
because of its
multi-layering, and
difficulty to get it
into focus. It
naturally occurs in
sluggish swamps,
bogs and fens. This
portion of the
Mattawoman is dark
tannic colored, and
averaged three feet
deep. |
 |
Here is a close-up
of the flowers,
which stand about
two-inches high, and
are about half the
size of a dime. |
 |
This particular
clump was growing
from a hollow knot
of a fallen tree, in
the water. |
 |
We have a little
cubby on the top of
our cooler, and I
tried to spread the
bladderwort so that
you could better see
its floating root
system. The black
dots in the photo
are under-water
bladders, which
makes the plant a
carnivore. When
swimming prey, such
as aquatic insects,
touch the trigger
hairs surrounding
the mouth of the
bladder, a
trapdoor-like flap
of tissue swings
open and the bladder
quickly expands,
sucking the tiny
critter inside.
Enzymes are secreted
to dissolve the prey
into nutrition for
the plant. How cool! |
 |
Another flower along
the banks that was
at peak bloom was
the pink wild bean (
Strophostyles
umbellata ). It is a
southeastern US
native legume
(nitrogen fixer) of
sandy soil, and
flowers from August
into September.

This plant is marsh
St. Johnswort (
Triadenum virginicum
). It occurs in bogs
and swamps and is
also a southeast
native, and flowers
from August through
October. |
 |
This is the only
species of several
St. Johnswort's that
is pink and not
yellow. |
