Hiding in the Open

Field Observations:

Today I went out to the Lowland forest in order to gather four new species to identify and for some relaxation.  Heading into the lowland forests allows me to find a place of relaxation, a place where I can sit and enjoy the sounds of nature.  All around me I could hear birds singing, animals running through the treetops and the leaves of the forest rustling in the wind.  It was a great day to observe the forest, sunny and in the seventies with a breeze rolling through the woods.  Today, sunlight was reaching further to the forest floor, emphasizing different aspects of the woods.  Immediately I noticed just how dark the soil was, from all the decaying organic matter and the moisture.  I also noticed that the soil was a bit dryer than last week, it was still moist, but in some areas it had begun to dry a little. 


As I walked a bit longer, I happened to look up towards a tree and saw something that I wasn't expecting.  When I looked up, I saw a willow that had grown almost horizontal to the ground, making an arch and up on the tree was an adult groundhog.  The ground hog was taking advantage of the sunshine as well, it was laying on the tree taking a nap.  I was able to get close enough to the ground hog to take a few pictures of him, but as I approached he awoke and eventually ran back to his den.  It was neat to see a ground hog, almost every week I am able to spot a different animal in the lowland forest.  In addition, to being able to see animals, I saw a Ruby Medowhawk which was the first dragonfly that I've seen in the lowland forest. 


New Species:

Buttonbush
(Cephalanthus occidentalis)

The buttonbush is a multi-stem shrub that can grow around six feet to twelve feet and sometimes even taller.  The leaves of the buttonbush grow in pairs or in whorls of three; the blade is up to eight inches long, ovate, pointed tip with a rounded base.  The leaves also are dark green, having smooth edges, a glossy upper surface and the lower surface is dull.  The flowers are small, dense, spherical clusters and are long lasting, usually white or a pale pink in color.  There are subsequent rounded masses of nutlets that persist through the winter.  The branches grow in a twisted form, as a small tree like shrub with many branches.  This plant gets its name from the flowers that look like small buttons.  The buttonbush grows very well in wet soil, along wetlands, temporary wetlands and lowlands; this is why it is found in the lowland forest.

Sycamore
(Platanus occidentalis)

The sycamore tree is a common tree in Indiana, one of the largest in the eastern deciduous forest.  It is also referred to as American sycamore and the buttonball tree.  It is a fast growing, long lived tree that grows well in lowland forests.  The leaves are palmate, with three or five lobes; the edges of the leaves are wavy and serrated.  The top of the leaf is bright green and the underside is a pale green.  They also have long petioles.  The trees have large, strait trunks with pealing bark and spreading crooked branches, creating a wide crown.  The bark is smooth, whitish and peels off in large flakes; it looks splotchy where the bark has peeled off.  Another identifying mark is that the twigs looked zig zagged.  The sycamore is found in forests that are along edge of streams, lakes and pond, they enjoy wet soil and this is why it is found in the lowland forest.  It commonly grows in groups with silver maple, red maple, and black willow.

Ruby Meadowhawk
Genus: Sympetrum
Species: rubicundulum

The ruby meadowhawk’s range is from the Great Plains to Maine and it is commonly found around Merry
Lea. The head of the dragonfly is yellow/brown, the thorax is deep red to brown, the abdomen is red to brown as well, and the wings are veined. Their hunting strategy is known as, “sit and wait” approach to hunting; they sit on plants and then dart out to catch insects. This strategy allows for much less energy required while hunting. This dragonfly will use the sun’s rays of light to warm themselves and often bask on the ground out in the open. The adults will die when winter hits and the newly hatched nymphs are able to survive the cold winter under water. The preferred habit for the ruby meadowhawk is wetlands and lowland areas; this is why I was able to find this in the lowland forest.

Groundhog
(Marmota monax)

Order: Rodentia
Family: Sciuridae

The groundhog is also referred to as a woodchuck; it has course fur that is brown to yellow brown, with gray or yellow tipped guard hairs.  The feet of a groundhog are dark brown to black.  It also has a stocky, low compact body with a broad head and a short bushy tail; the ears are small, rounded and inconspicuous.  After birth and being weaned from the mother, they will mature at eight weeks of age and able to live life on their own.  It doesn't fully reach adult size until about two years of age.  The groundhog is a diurnal forager that feeds mostly on grasses, green plants and leaves; at sometimes it will feed on invertebrates.  It lives in burrows that they make themselves; they can be deep in the ground and can have several entrances for safety.  The main entrance of its burrow has a mound of excavated soil that serves as an area where the groundhog can bask in the sun and keep watch for predators.  The average lifespan is around five to six years.  Predators include: fox, coyote, eagles, hawks and owls.  The groundhog is commonly found along ecotones, along rivers and lowlands, this is why I was able to find it in a tree near its burrow at the edge of the lowland forest.

Ecotones:


“An ecotone is a transitional area between two different ecosystems, such as a forest and a grassland (Graves 2010)."  When observing the ecotones surrounding the lowland forest, I am able to notice a few
Diffused Ecotone

Convoluted Ecotone
different ecotones. The first one I notice is due to a man-made structure, a driveway. It abruptly ends the lowland forest and creates a distinct edge. This is where there are several more plants present, due to sunlight and these are ones that are not easily found in the forest. I would consider this ecotone to be a diffused ecotone, because of how abruptly it ends. Another ecotone that I notice is the area where the lowland forest transitions to a drier area with less lowland species of trees and eventually to a meadow. The meadow is maintained by cutting the grass and not allowing it to grow naturally. The forest shifts form having a wet, decaying organic floor to a much more dry soil and leaves that are crunchy. It then transitions to more of a meadow. I would consider this to be a convoluted ecotone because it is not a smooth transiton with bushes and large plants to the meadow.  It goes from trees and then almost directly into the grasses and flowers. This is the area where I was able to view the Ruby meadowhawk . I was able to see the groundhog along the ecotone caused by the drive way, its burrow was only a few feet from the road.

My favorite poem was written by Robert Frost, “The Road Not Taken.” When I looked down this lane I thought of that poem, where the lane is the easy path, the wide path that all visitors can take when exploring Merry Lea property. But I am taking the narrow path, the one that not many take, off the beaten trail. You could take the beaten path and see some beauty, animals, insects, and plants, but on the path less taken you see the true beauty of God’s creation.


The Road Not Taken

By: Robert Frost

Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;


Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,


And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way,
I doubted if I should ever come back.


I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I—
I took the one less traveled by,


And that has made all the difference.

The Canopy to the Forest Floor

Field Observations:

 It is Sunday evening; I arrive at Merry Lea Learning Center, driving none other than my Eco-friendly Ford Festiva.  I appear to be the only one at the learning center, which will make for great observations, I lace up my boots, grab my pack, ID guides and my chair.  I take off down the gravel path towards my lowland forest.  I hike into the forest, in search for a good area to set up camp and to make my field observations.  As I sit down to observe the forest, I notice that it is relatively quiet, the sun is slowly making its descent across the clear sky and the bugs quickly find me and begin to attack.  It is a peaceful evening, the temperature is in the low seventies, and a calm breeze sweeps through from time to time.  The breeze carries the distinct aroma of decomposing forest matter as well as the sounds of forest life.

As I quickly sit and wait for the woods to become accustom to having me as part of the ecosystem, I begin to hear sounds of life.  To my right, a pair of woodpeckers is hammering the tree with their beaks in search for worms below the bark of a tree.  Behind me, a squirrel scampers down a tree and then limb to limb, treating the woods as his personal jungle gym.  The sound of tree tops rustling above from the breeze slowly picks up and then dies down again.  As I glance around to observe the vegetation, I notice the area that I am in is dominated by maples and willows.  The forest floor is spotted with ferns, false nettle, poison ivy and millions of sugar maples fighting for survival.  Since my last visit to the lowland forest, not much has changed, the moisture is about the same and the vegetation similar.   

New Species:

Black Willow
(Salix nigra)


The black willow is a medium tree with spreading, irregular limbs and has small branches that usually droop a bit.  It has alternate, narrow, curved, lance-shaped leaves and the the branches are brittle.  The leaves are finely toothed, bright green on the top and the lowers are pale green.  The bark of the tree is dark-grey brown to black and is deeply furrowed.  The black willow is common on wet sites along stream banks, in low wet woods, this is why it is found in my lowland forest.  The willow has several common uses which include: barrels, boxes, creates and can be used as an erosion control of stream banks.

Slippery Elm
(Ulmus rubra)

Slippery Elm is a medium sized tree that is native to North America and can reach over a hundred feet tall with a spreading crown.  The leaves are very rough and sand-papery on the top and the underside is hairy.  It flowers in March to May.  Slippery Elm has been used in North America for centuries as an herbal remedy.  Native Americans were the first to use slippery elm in healing salves for wounds, boils, ulcers, burns and skin inflammation.  The inner bark is dried and powdered, which is used as the medicine.  The slippery elm received its name because the inner part of the bark is very slippery when cut or torn from the tree.  It is commonly found in a flood plain forest or bottom land woods, it is common in the lowland forest of this area.  It is also common because the Dutch Elm disease really attached the american elm more readily than the slippery elm

Royal Fern
(Osmunda regalis)

The royal fern is a large fern species from a distance, but up close it has the appearance of a locust tree or a possible member of the pea family.  It grows in erect clusters, has bright pale green foliage when in sunlight.  The leaves are oblong, slightly alternate, have eight or more pairs, are slender and rounded.  In areas with high level of water, it can reach heights of six feet.  It prefers swamps, low woods, along stream banks and marshes, that’s why it is found growing so abundantly in the lowland forest.

America (Second ed., pp. 176-177). New York, NY: Houghton Mifflin Company.


Pin Oak
(Quercus palustris)

The pin oak is a medium to large tree that has a pyramid-shaped crown with drooping lower branches.  Leaves are long, deeply lobed, having 5 to 7 lobes, dark green, shinny, smooth and bristle tipped.  The leaves ill change color in the fall from a dark green to a deep red.  The bark of the tree is smooth, reddish to grayish brown at a young age, it slowly becomes darker and somewhat fissured.  The pin oak occurs on moist floodplains, along edges of swamps or ponds.  It is found in the lowland forest due to the organic and very wet soil.  Pin oaks can often be confused with scarlet oak, due to similar appearance, but the scarlet oak prefers upland soils with good drainage.

Succession of the Lowland Forest:


The lowland forest that I am observing is in later stages of succession, once disturbed and experiencing secondary succession. Jackson (1997) states that cleared forest land will gradually transform though a succession of weeds, forbs and grasses, then it will give way to blackberry briars and golden rod. After that, a brush fallow of young saplings and another 20 or more years later, small trees, shrubs, and flowering herbs begin to dominate the area. This is a shortened version of the process that takes place for secondary succession.

It looks as if the area has experienced secondary succession, from previously being farmed and possibly grazed due to the heavy amount of water that stays in the area. There are many dominate oaks in the lowland forest, along with red and silver maples, black and green ash, and other species that hint at the fact that the forest has been under succession for a very long time according to Jackson (1997). In the future, the lowland forest will succeed to another type of forest, with different flora and fauna types. The lowland forest most likely began as a small lake or marsh; later it was probably drained for farming. Once it was turned back into a forest, it began to be taken over by trees; the organic matter is slowly filling up the lowland forest. It the future, the trees and plants will slowly change to a mixture of maple, oak and beech forests that will eventually then change to an oak-history forest. Over time, as the soil loses it high amounts of moisture, new trees will dominate the area, trees such as the willow will struggle for survival, as the area will become a much dryer one. This change will not be sudden; it most likely will take hundreds of years, for this to happen. The forests will succeed to being dominated mainly by oaks and hickories.

In the face of tragedy and death, there is a wonderful creation of life! During a storm a few years ago, it looks as if this tree was uprooted and toppled over, leaving behind a shallow wetland. This area is springing with life; I came upon it as I was hiking around the lowland forest. As I approached the uprooted tree, several frogs jumped under the water for hiding and there were several small frogs all around the pool. It was amazing to find a small wetland within my lowland forest, springing with life that was different from the surrounding area.

Dark and Mysterious

Field Observations:

As I walked along the gravel drive that passes the Merry Lea Learning Center, towards the lowland off to the right, I instantly noticed a huge change.  The insects seemed to come alive once I entered the lowland forest.  It was a very warm, sunny Saturday afternoon and as I stopped to take a picture of a false nettle plant along the edge of the forest and within a few seconds I was covered with fifty or more mosquitos.  Not far behind were the horse flies, who for some reason, really liked the top of my head.  As I was surrounded by these pesky insects, I could tell that I was entering a much wetter and darker environment. The woods was alive with insects, birds calling, toads hopping and a few rays of sunlight making it to the forest floor.  The soil in the woods was very dark, rich with dead organic matter, it was spongy to walk on, but water did not seep with each step taken. 

This was the first time stepping foot into the lowland forest that I will be studying over the next two months; it was a very exciting feeling.  It was dark, humid and full of life.  Below the canopy, lie young saplings waiting for a chance to take over when one of the larger trees dies or is taken down by a storm.  In addition to young saplings, there are smaller types of plants, including ferns that occupy the forest floor.  While walking
through the lowland forest I came upon tracks in the moist soil, the soil was in perfect condition to be a mold for the animal that left behind the tracks.  I was able to determine that the animal tracks were that of a white-tailed deer.  It looked as if the deer was passing through the area, possibly looking for some berries or other food types.  I also came across a small American toad that was trying to escape the wrath of my boots as I clumsily steeped without taking a look towards the ground.  I was able to safely navigate around the toad, as to not crush it, but observe the dark areas of the lowland forest. 

New Species:

American Toad
(Bufo americans)


These toads are very common to Indiana and this area particularly, they can grow up to four and a half inches long and the adults usually look chunky.  The toads can vary in color, in order to match their surroundings, the colors include: brown, brick-red or olive.  They all have warts on them at adult stage and have patterns of lighter colors and brown spots.  Both the male and female have a spotted belly, but the throat of a male is much darker.  They are common in a lowland forest due to standing water in the spring, in which the male and female will mate; the female will lay thousands of eggs in a string in shallow water.  The tadpoles will hatch, leaving the water eventually to hop around in search of food.  These toads have a very pleasant call that sounds similar to a cricket.

False Nettle
(Boehmeria cylindrica)

False nettle is a perennial plant that is about two to three feet tall.  It is a member of the nettle family, often it can be mistaken for stinging nettle, but there are no stinging hairs on a false nettle.  The stems of false nettle are light green, 4 sided or round, the leaves usually are opposite on the stem, in rare occasions they can be alternate.  Also, the leaves are ovate or ovate-lanceolate in shape.  The false nettle prefers shade, moist, rich loamy soils and this is why it is very common in the lowland forests. where it gets It is heavily populated along trees lines, lowlands and wet areas with shade.

Sensitive Fern (Bead Fern)
(Onoclea sensibilis)

This is one of the many ferns that grow in Indiana and this lowland forest; it thrives in organically rich moist soil and enjoys part to full shade.  It grows tall, eighteen to twenty-four inches in wet soil and can spread aggressively along rivers and streams.  It claimed is name from the fact that the green vegetative fronds suffer almost immediate damage from fall’s first frost or from a severe drought.  The roots will colonize, despite being bulky they are still shallow.  The other common name derived from the thought that the ferns look as if they have a decorative beaded appearance.

Red Maple
(Acer rubrum)

A red maple is a very common tree in Indiana and in North America, it can grow in both dryer and wetter areas, it particularly thrives in the lowland forest because of the rich organic soil and the moisture.  The red maple seed are very shade tolerant, has a high percentage of seed germination and are able to be suppressed for many years before taking its place in the forest canopy.  The maple sapling growth is slow in its beginning, but as it receives more sunlight it will grow a more extensive root system and increase growth.

/rubrum.htm


Dominate Vegetation:

The dominate vegetation in the lowland forests mainly persists of trees, they occupy the canopy of the forest and dictate the amount of sun that will make it to the forest floor.  The trees dominate this area for a few reasons, the first is that the rich organic matter and high amounts of moisture allow for the trees to obtain sufficient nutrients to survive all year and continue to grow year after year.  Also, trees were able to exploit the resources available better that plants and shrubs, over time beating out the other plants for sunlight and nutrients.  This is not to say that only trees exist in this area; there are several shade tolerant plant species that enjoy the wet conditions.  Some of those plant species include ferns, false nettle, stinging nettle, mosses and many more.  The area is primary dominated by a range of trees which include: swamp white oak, silver maple, sugar maple, cottonwood, oak red, sycamore and black willow.
