Field Notes
Field Notes On October 16th, our science class went for a walk to find Loosestrife in a near-by wet area. We strongly believe we found it. We went to find Loosestrife so that we could see if it was a big problem, or a small problem that can only get worse. We also went to see if the Loosestrife eating beetle, Galerucella, was needed to help control the Loosestrife population. In our group, 72as80 was the photographer, 72ep77 was the “adventurer” so she explored our quatrat‘s area, 72jr78 was our equipment manager, and 72ks79 was our journalist. The temperature was 10 degrees Celsius Time was approximately 12:50 p.m. Weather was windy and chilly outside Our area is wet and muddy In our quadrat, we found 34 plants that we believe are dead Purple loosestrife. The plant has a square stem, flowers at the tops, lance shaped leaves, and hairs on the stems, just like Purple loosestrife.

This picture shows the tops of the plant that we found, if it wasn't dead, we think that they would be purple like loosestrife.

This photo, shows the square stem that our plant has. Which is another thing that this plant and Purple loosestrife have in common.
