A sketch of our study site.
My science class and I had gone outside to research what kind of plants were growing around our school. Each group had a quadrat, and in our quadrat I have been researching a certain type of fern and I think that it may be call the sweet fern. In the quadrat area the average air temperature is 13.8 degrees celsius, the humidity is 33%, wind speed is 0 mph and the soil temperature is 10.6 degrees celsius. The habitat where my plant is growing is nearly at the edge of the forest and is a wetland. The surrounding area of our quadrat is pavement road, and the interior of the quadrat area has mushrooms, a variety of plants and pine trees. The leaf shape of my plant is in blade form, the leaf arrangement of the leaves are alternate, on my plant there are leaflets on each leaf, there are 38 leaflets to each leaf. The veins on the leaves lead out into each leaflet. The other characteristics of the leaves are that they are a dark green and when seasons change they change to a darker brown. The petiole (stem of leaf) is flat. The size of the leaves are 12 cm of height. The branch arrangement are opposite and alternate.When you look for the comptonia peregrina you need to look for a low growing shrub reaching to about 1.5 meters tall. My plant isn't that tall but it still may be growing. The stem has little hairs, and is rounded. And finally the size of my plant is 83 centimeters in height or 33 inches in height. Also During my research I had put a plastic bag around my plant to see if there would be any water collected the next day and there wasn't. I have also wondered how my plant survives, I found out that it needs light to allow photosynthesis process of converting carbon dioxide to growth sugars to take place.
Supporting Evidence

According to the vital signs comptonia peregrina, or the sweet fern, the leaves are lobed. The plant that I am researching around my school the leaf shape is also lobed.
Photo of my evidence.
The comptonia peregrina, or the sweet fern has a reddish brown stem color and little hairs all over it. The plant that I am researching also has that same color I noticed and also has hairs on its stem.

When you look for the comptonia peregrina, you need to look for a low growing shrub reaching to about 1.5 meters tall. My plant isn't that tall but it still may be growing.

Comments

This is an outstanding submission. Well Done!

Thank you, I had gone out recently with my class and my plant was not found

Thank you very much! I worked really hard on this.

Great job. Awesome field notes. They contain great descriptions of your quadrat and the surrounding area. Reading them made it clear as to what the area is like. You also really looked closely at your plant and described it with so many details. The more details you documented, the easier it was to narrow down what your plant was.
Great job with your evidence. Nice, clear closeups and descriptions. Nice job identifying Comtonia peregrina. I guess there are other ways to confirm that your plant is Sweet fern. You'll have to give it a try this Spring (if the snow ever melts). Hope your plant survives the winter!

You have the makings of a first rate botanist. Very abservant and your descriptions are nicely detailed.

Thanks a lot, I appreciate it!

Great job with your research! I think you had very clear photos helping people see the details. Great comparisons!
