Pond Area

Eric, Paul, and Ben


The_REAL_POND_image_for_BIO2.jpg
Our transect line is located at the manmade drainage pond, which is to the left of the back driveway, behind Great Valley High School.

Water is the most noticeable quality of our plots. Plot ten is its own micro-climate because it is the only area with water submerging its soil. Plots three, four, and nine comprise another micro-climate. It borders the water, bringing diverse plant life, without flooding the area...normally. Plots one, five, and six are beyond the immediate area of the water. Flowers and weeds mainly inhabit this area, preferring less soggy soil. Beyond that, plots seven, two, and eight make up the last micro-climate. Only grass and dandelions grow here, most likely because of a regular visit from the lawnmower. What else do you normally see around water besides plants? Insects. If you refer to the plant information, you'll see that some are pollinated by insects. Plants also flourish here because the sun is less blocked by tress than the woodsy areas nearby. Our pond is full of surprises, which we hope to uncover.

Climate #1: Plot 10

Plants: Cattail and Yellow Fox Tail
Location: Water
Description:This micro-climate is relatively bright, and, unless there's a drought, filled with a few inches of water. Since our area is far from trees, the sun is unblocked. The slope and the pipe provide a large amount of runoff from precipitation, keeping its soil moist. The cattail, submerged in fresh water and protected from the lawnmowers, grows in this ideal area. In the water, there seems to be almost an island that also allows yellow fox tail to grow without being completely submerged.

Climate #2: Plots 3,4,9

Plants: Golden Rod, Flee Bane, and Ironweed
Location: Water's edge
Description: Like the water area, it is constantly in supply of water and unblocked sunlight. Because this area is not submerged in water, thick brush can grow. Golden rod, because it likes well drained areas, cannot be in the water area. It prefers full sunlight, like flee bane. Flee bane is successful here because it needs insects to pollinate it. Ironweed, however, can grow in the shade and prefers woodsy areas. Thankfully, the lawnmowers also don't mow this area, being so close to the water.

Climate #3 Plots 1,5,6

Plants: Smart weed, Yellow Fox Tail, Buttercup, common grass
Location: area beyond water's edge and before the grassy slope
Description: This area is by far, the most diverse area. This is the sunniest area, out of all of our micro-climates. Being in moist soil without fear of being flooded, typically, more flowers and grass grows here. This area can be described as "light brush."The yellow fox tail grows in this area, like the water, because of the moist soil. The smart weed is a survivor, growing anywhere it can. The buttercup is usually found by streams because it needs insect pollination, like the flee bane. At the edge of this area, the lawn mower starts to move in.

Climate #4: Plots 7,2,8

Plants: Dandelion, common grass
Location: Grassy slope
Description: This area is cut down regularly by the lawn mowers. Only common grass and dandelions grow here. A lot of sunlight is given to this area, but because of the angle of the hill, it is only the second sunniest area. The grassy hill is not nearly as moist as the other micro-climates, but has some moisture.

Plant Information:

Cattails

Cattails are commonly found in ponds, rivers, marshes, and lakes.Cattails prefer freshwater, and don't germinate unless they are in at least 1/2 to and inch of water. Cattails are densely packed together and are usually in the water.The plants can grow up to about 10 feet and their stalks look like one inch wide blades of grass. Their flowers have two parts: the (female) brown cylinder, and the (male) yellow spike on the top.Cattails have starchy rhizomes, also known as creeping root-stalks, which are the anchor for the plants with horizontal roots embedded in the soil. The dense population can become entangled with their roots, which further protects them from being eroded away.

Flee Bane

Common Flee Bane are commonly found in fields and grassy areas. They can be 6-30 inches tall with a typically half inch wide pink or white flower. They prefer sunny areas and areas by paths. They are pollinated by insects, which is ideal when there are by water, which attracts insects.

Yellow Foxtail

Yellow foxtails are generally found throughout the united states specifically on fertile soil. Commonly, they are found on lawns, fields, along trails and railroads, and by rivers.Weeds are rolled into a bud, with small hairs about ½ mm long. The stems are flat long, and hairless with an erect body. The roots are very fibrous and do not root at the surface. They are commonly found in sunny areas and moist to mildly dry areas. Yellow Fox Tail can tolerate mowing and can aggressively spread in disturbed areas.

Goldenrods

Goldenrods are all perennials with large clusters of small yellow flowers that appear from the end of summer until frost. The leaves of goldenrods are simple, egg shaped and usually have a toothed margin. Most species propagate by a spreading root system in addition to seed. They can be a troublesome addition to a wildflower garden for that reason. They become more common in pastures under heavy grazing pressure and can grow easily in moist places. Goldenrod prefer full to partial sun, and well drained areas. Some types of Golden rod can grow up to 5 feet. Just about every insect with an interest in flowers may be found on goldenrod in autumn.

Dandelion

Dandelions are perennial with a stout taproot. Their taproots can grow three feet into the ground to "tap" into water deep in the soil when there is a drought. Dandelions are common in pastures, lawns, orchards, hay fields, waste ground and roadsides. They are pioneers to disturbed soil and possess the constitution to withstand as an established vegetation. Dandelions can reproduce asexually, as well as by wind-dispersed seeds. Dandelions can duplicate themselves through the roots, and by severed parts of their roots. Dandelions can also negate fertilization, and send clone seeds without another dandelion. They typically reproduce throughout spring.

Ironweed

This is a herbaceous plant, it is a perennial which can reach a height of 3 Meters. The leaves can reach 25cm in length. Each lanced shaped leaf is very finely toothed. The flowers are deep purple. Blooms first appear in mid summer and continue into mid fall. The individual flowers are tiny and this species usually has from 13 to 30 flowers per head. The heads are about 1cm wide when fully opened. The Ironweed grows in moist fields, near water, or open woods throughout the east and southeast.

Buttercup

The buttercup typically can be found by the edge of streams and ponds, and on lawns and roadsides. They have five pedals, concave or convex in shape, that are yellow with a waxy complexion. Buttercups posses a thin stem, and the plant itself may grow to be a meter high. The meadow buttercup has an acrid and poisonous juice that dissuades its consumption from herbivores. Most of the pollen can be found on the petals, if closely examined. The green pistols at the center of the buttercup house the immature ovaries. The plant spreads its pollen by bees and flies, and can sometimes cause self fertilization, which is rare.

Common Grass
Common grass is one of a number of plants with the unique ability to grow almost anywhere. It occurred in most of our microclimates and most habitats all over the world. Its ability to tolerate excessive rain or snow, wet or dry, and even unharmed or disruptive conditions allows common grass to grow in nearly any location it wants. It grows very efficiently in our plot where there is good moderation of weather extremes and does not have too much interference.
