Purple Loosestrife Research Question -Has Purple Loosestrife been spreading across Massabesic Middle School Campus? -Are Galerucella/Japanese beetles spreading/in abundance? Purpose Invasive species are a problem, and we are trying to monitor them, and keep track of what is growing. Mission Taking a population count of purple loosestrife, and if there are any beetles, counting those too. We used sample counts, quadrants in the exact same place we looked before, each person had a corner within the quadrant for them to find and count the purple loosestrife. We were hoping that if it is purple loosestrife, the galerucella beetles would become a limiting factor, but we still aren’t sure if it is. We went out a second time, to determine whether or not it is purple loosestrife. -Over-all area The ecosystem in which the organisms were found in a pond area, surrounded by roads and parking lots, when the weather is rainy the pond floods, and when the weather is dry for a long period of time the pond is flooded. Very grassy, more wet on one end the the other. The pond was fairly wet the day we went out. -At the quadrant The habitat was fairly dry, the ground was moist, but not soaked, considering that all week it had been raining, it was considerably dry. Very grassy, few plants other then long grass and (what is suspected) purple loosestrife. one of the dryer quadrants had less grass then the other three. -Abiotic Factors time: 10:15, May 9th temperature: 13.8 c˚ humidity: 63% Sunlight: little, fairly cloudy soil moisture: damp other: little wind, and very misty The second day time: 10:30 temperature: 20˚c humidity: 67% sunlight: little, very cloudy, overcast soil: Wet, muddy other: no wind, felt warm Observations One side of our quadrant had less grass then the other three, it also had less water. our The whole area was relatively dry, the ground was damp but it had been raining for days before. The pond was mostly dry on one end. It definitely smelled swampy, it was fairly warm outside, but very wet. We found the plants, that are suspected loosestrife, but we found two types of plants that look different from each other. One looks more like purple loosestrife then the other. The plants that look more like purple loosestrife had little holes in the leaves, but no beetles were found (in our area, i noticed some other people found beetles). Some of the plants also had white things a the base of them, slightly underground. They were very small, and we could only tell the were round by getting really close to them, It looked like their were hundreds of them. We found the same thing on a few more plants. The biotic potential is very high for purple loosestrife, it has many many seeds, with little limiting factors, and if these new organisms are purple loosestrife, then the birth rate is going up quickly. Data/Evidence We were trying to do a population count on how many (suspected not confirmed) purple loosestrife is by the pond, my group and I found 34 plants in our small quadrant. 7 12 10 5 Each number in the square represents how many purple loosestrife we found in each corner of the quadrant. We also wanted to see if any beetles had been eating at the purple loosestrife. We found leaves on the plants with bullet like holes, the same way galerucella eat the plants. Second day: We looked closely at the loosestrife, and determined that it wasn’t loosestrife. The base was reddish, the leaves were long and lance-shaped, but the stem is round, not square.

it has many of the same characteristics as purple loosestrife, like the lance shaped leaves
Photo of my evidence.
it also has a reddish base like purple loosestrife

The Drawing that you did was very good!

The pond area from 40-50 years from now, I think the pond area is going to be dry. The rain could absorb into the pond, but after years to go through, it could dry up because of how much it rains decrease, it could drop the pond water to nothing. Though, the reason why rain could decrease, is because maybe somewhere in the cycle, it could get stuck. When the rain cycle goes around, it has to go from the ground, to the clouds. Maybe the clouds could trap some of the rain while it goes through the cycle. The invasive species in the area could increase because the rain is the only thing that plants need to survive, well some of the plants need rain, but others need the sun light. Invasive species need other species, or plants, to survive. They take over the area over a matter of time. Plants in the area could decrease, if the invasive species increase, or if the plants don’t have enough water, they could die, or be over run. If this does not happen though, the area could become a home for invasive species. We have purple loosestrife here in our area. Maybe this plant could expand and make more plants. Maybe if Wooly Adelgid is in this area, it could expand and take over and kill off the Hemlock Trees.

My predictions about the Pond Area near Massabesic Middle School 5, 10, 20, and 50 years from now. Will be probably similar succession. If water will continue to flood, it will maybe because of the rain. If it is not will going to flood, maybe because of the temperature of the day. If its hot, the water may be normal. It might change the water over time because of weather and temperature changes. I think that nothing will be going to change with the Invasive Species because once they live, they will still grow 5 to 10, 20 years from now. They might spread everywhere and they will still grow. There might be new Invasive Species that might also causes changes the Pond Area over time. I think that 5 to 10, 20, 50 years from now, there will be more trees that will grow and plants in that area or it will be different because of the new Invasive Species that will grow in that area. The changes possibility that the Pond area is that trees and the plant that will grow, but we might never know that 10 to 50 years from now there might be animals that are new that come from different countries. Im not sure if something will something will happen to the animals and the plants. Like no water, no food for the animals I think there’s a possibility that they can die. Im not sure if what kind of plants and animals may able to be present in the different stages. It may happen that the animals and plants change over time because of the new invasive species. Maybe animals and plants that we already have might have a chance to go to another place. That may be the change over time.

I think that the pond area will continue to flood for 5 years because the rain easily fills it up with water but it will change over time because there could be a drought and then when it rains the soil will absorb all of the water and it will not flood. I also think that succession might have a chance to take over because of the soil condition but if the flooding does not reduce over time it will probably not grow as fast. The biodiversity will grow in 10 years because in either scenario new plants and animals will be introduced especially by invasive species including Loosestrife, Gallerucella and Japanese Beetles I think the loosestrife will eventually die off in 15 to 20 years because Gallerucella and Japanese Beetles eat it. I think the biodiversity will be different either way if the pond floods there will be new amphibious and fish life and if succession takes over new animal land life will take over. In 50 years succession will take over because it has had enough time to grow.

My prediction of how the pond area will change over time through succession.
I’m predicting that five years from now, the pond area will be quite similar. Succession takes time, many many years, so five years not much will have changed. I’m guessing there might be slightly less water, and a few more plants growing on the ground. The biodiversity might stay about the same. There could be new, or different plants growing if there was less water, but not much will have changed. I think it will continue to flood, but not quite so much. The pond doesn’t look much like a pond now, there is only water at the end. I predict that the water will dry up some, considering there is only deep water at the end of the pond. I also think that the loosestrife, (not what is shown above) will have spread some, but not take over. It has been monitored for awhile, and it hasn’t seemed to spread much, so I don’t think it will take over in just five years. As for the invasive bugs, if there isn’t much loosestrife, then there isn’t much food for the bugs to really move in. Other then that, not much will have changed.
I’m predicting that ten years from now, the pond will be more of a marsh, very wet, but not enough water to still be a pond. I’m assuming the deeper water will have drained from the pond, or dried out, but the ground, soil, and plants that live there will be watery. I think the biodiversity will have changed. From plant that grow completely under water, into plants that mostly are in water, but also live without being in water. I suspect that the loosestrife will have spread some more, but more trees, and smaller plants will have filled the space. The seeds from the plants around the area will have moved in more. The loosestrife is the main source of food for the Galerucella beetles. So if the loosestrife spreads, the beetles will have more food to eat and be able to grow in population. The pond will look less like a pond and more of a marsh. Succession will be in play.
Succession will have taken place dramatically in twenty years, as long as the pond area hasn’t been altered. Most of the water will have drained from the area, and left mostly trees. Since the water level will have dropped, the organisms that live there will have changed. Most of them living on dryer land, like the pine trees around the area. The seeds carried in by the wind and animals will have started to grow, so the area will look more like what is around it. The animals will most likely be rodents that live in forests. I’m assuming that the loosestrife likes more watery areas, so if the pond has dried then the loosestrife will have died down, at least some. If the loosestrife dies down then the Galerucella beetles will have too. Leaving more space for new, more adapted plants to grow. More trees will have grown in, and less plants will be on the forest floor. The area will look a lot like what is already surrounding it.
Fifty years from now, the forest could grow into a climax community, with tall trees and little plants on the ground. The area would be dry, with tall strong trees, a very stable environment. The pond water will have drained from the ground, leaving the ground wet only after rain and snow. The trees will be of the same species surrounding the current area. If the water is mostly drained then loosestrife might not survive there. If there is no loosestrife then Galerucella beetles won’t be there either. There will be mostly trees and little water, except for when it rains and snows. The ground will be hard, dry, and shaded, causing few plants to really grow. The animals populating the area will just be small bird or squirrels that live in the trees.

I think the pond area will either be flooded or overgrown by succession.

Great job about the Loose strife. I now think that I am lazy.

wow

That's an awesome sketch! Nice work.

good job you did a great job in identifying the characteristics .
