Ahh, the iconic Bigleaf Maple tree! Acer macrophyllum for all my fellow nature nerds & dendrophiles out there; this is an incredibly common deciduous tree all throughout Cascadia known for its massive leaves. Truly one of the most gorgeous trees around, I love 'em!

Transcript:
"Bigleaf maples are icons of lowland forests in the PNW, often found in areas of disturbance such as riparian zones or logging areas alongside other first generation successors like douglas fir. Their scientific name is Acer Macrophyllum - Acer being the name of the genus for all maples, and macrophyllum basically breaking down into ‘macro’ or ‘big’ and ‘phyllum’ which stems from the greek word for ‘leaf’.

Bigleaf maples are easy to identify from afar because of their wiggley outline with low sweeping branches, and are usually covered in thick mats of moss, lichen and ferns. These trees are actually known to carry the highest quantity of epiphytes than any other in our area, and mosses often grow so thick on oldgrowth big leaf maples that they form a soil of their own which allows other species of mosses as well as ferns and even small sprouting western hemlocks to take root.

Up close, you can identify a big leaf maple by its bark, which starts green and smooth in young trees or shoots and grows greyish brown with age. Although the easiest way to ID them are by their massive maple leaves with are commonly the size of your face! Now, while the classic maple leaf shape is a common characteristics of all Maple trees, their fruit is pretty easily identifiable as well. In the spring, Big Leaf Maple flowers form neary the leaves in drooping bunches of small, light green flowers which - side note - are delicious to fry up and eat. After the bees, birds and insects do their thing, the tree forms paired winged fruits like this, which is commonly referred to as a ‘samara’. You may recognize these funky little winged nuts from other forest walks, and this is an example of some crazy bioengineering at play - see how these wings resemble propeller blades in a way? When these fruits fall from the tree, they spin in a similar way to airplane props which slows the rate at which they fall, making them more easily swayed off-course by winds, which then take the seeds further from their mother tree and thus helps the species propagate and spread into new areas."
