Field Notes
Our team went out Thursday september 19 and 23 to see if Lythrum salicaria (Purple loostrife) was spreading, and to collect data. The evidence we have collected will help scientist in figuring out where these invasive species are. We went to look for Lythrum salicaria at 11:30, it was windy and in the mid 60's, it was also sunny. Our team searched for about 45 minutes, but gathered nothing that resembled Lythrum salicaria. Finally we stationed on something that resembled the invasive species we were looking for. The ground that we surveyed was moist because we were near a pond. The plant hat we observed was in a semi cleared area which was strange.

Supporting Evidence

Lythrum salicaria, commonly known as Purple loosestrife, is said to be 1 1/2 to 2 meters tall, but the plant that we have investigated is not. The plant in the picture (above) is 85 centameters tall. Our team has considered the fact that this could be a young Lythrum salicaria plant. We went back to observe the only Lythrum salicaria in the area to make sure we had rock hard evidence that this was not a invasive species. Thankfully the Lythrum salicaria seemed to be nearing the end of it's life, unlike the plant we were investigating, which seemed to be in very good health. Thus, concluding the fact that, this plant does not meet the specifications when it comes to height.

This picture shows how the stems of this plant are anything but Lythrum salicaria. The stems on this specimen are wood-like and round, the wood-like stems indicate that this is a perennial plant. Lythrum salicaria, has square, herbasios stems, Lythrum salicaria is also a perennial plant.

Lythrum salicaria is notorios for it's long and skinny stems, but once again we are further convinced that this is not an invasive specieces. The picture above shows how this plant is more bush-like, and has thick stubby stems, unlike Lythrum saliaria, which has long and skinny stems.
