BIOL 106-01 Field Trip to Muir Woods National Monument

On this day I drove up to north bay and into Mill Valley to visit Muir Woods. The temperature was perfect. The skies were clear and it was very sunny out. I have wanted to visit Muir Woods many times over the past couple of years and was never able to make it happen so this was the perfect opportunity! Initially, I was worried that I was not going to be able to find enough species for this project because I was half expecting there to be pretty low biodiversity. However, when I arrived, I was very shocked by the immense amount of biodiversity in the forest. This is easily the most biodiverse place that I have had to visit for this class. What I was not expecting, however, was the number of people in the park. I visited Muir Woods on a Tuesday afternoon and I was hoping that the park was going to be relatively empty. Oh boy was I wrong! Although the park was not overly crowded, there were still tour busses full of people visiting the park. With that being said, I think most people were there to stay on the paved paths and go over the bridges so, as soon as I got on the trail that I was hiking on (Canopy View Trail) and walked for a couple of minutes, the density of people went way down and I only saw a couple of hikers. The forest felt really peaceful on this day and it was wonderful to get outside and see some cool plants and animals. I saw and heard many different bird species on this hike but was unable to photograph them well enough for them to be identified by the app so I did not include them. Other than the birds I saw so many different plants and the wildflowers are in bloom so I got to take photos of many incredible flowers!

These clovers covered almost all of the forest floor, creating very densely populated cover low to the ground. Although these clovers were incredibly common, this was one of my favorite species that I observed due to the beautiful effect that they gave to the forrest floor

This flower has a really cool shape. It did not seem to be quite as common as some of the other species in the area which made finding it all the more special. Due to its shape, I assume that this is some sort of iris or lily. Also in this photo is a flower bud belonging to the same plant

I only found these small white splotches on this tree. I am unsure if this is a lichen or a fungus or something else completely. Due to the fact that I only found these on this tree, I think it is also possible that it could be some sort of disease or even evidence of a parasite on this tree. Although I think it is more likely to be a lichen, it was very odd that I could not find this growing on other trees in the area

With small serrated leaves and and long prickly stems, it makes me wonder why this plant needed to create prickles. Are they particularly yummy to mammals or insects? Is this a way to deter being stepped on or crushed? A combination of both?

This image was incredibly difficult to take and I struggled a lot trying to get the photo in focus. I was attempting to photograph the white foam and frothy bubbles sitting at the top of this plant. My guess is that this is done by some sort of insect. Perhaps a spittlebug?? This plant was found near Redwood Creek in Muir Woods

Fungi! At the time of my hike, the redwood forrest was cool and the ground was moist so I spent a lot of my time looking for fungi. This is the coolest one that I found. This fungus appeared to have a circular, ringed pattern on its surface, reminding me of oysters and other bivalves

These inflorescences were super common along the roads and open spaces of the park. As I moved into the forrest with more densely populated redwoods, I saw less on these plants. Each plant seemed to have only one relatively large inflorescence at its top. To me, this gave these plants the appearance of wearing a crown.
