PNW Silent Trees
Some of our Board members enjoying Silent Trees IPA.
This year we have partnered with Peaks & Pints to tell the stories of our favorite trees. Peaks & Pints was co-founded by longtime media pooh-bah Ron Swarner and restaurateurs Justin and Robby Peterson with the goal to create a welcoming and comfortable craft beer store, taproom and eatery. Peaks & Pints brewed their eighth house IPA at Loowit Brewing in downtown Vancouver. Because the brewery is named after Mount St. Helens, and its eruption silenced many trees, they named the beer Silent Trees IPA. Each week we work together to feature a new tree on their blog and social media, highlighting the beautiful and diverse trees in Tacoma.
Bigleaf Maple | č’uɫac | Acer macrophyllum
The English and scientific name of this week’s silent tree gets straight to the point–the leaves on this tree are BIG! So big that the Coast Salish tribes have historically used them to store food. They are usually 12 inches wide but can be up to 24 inches wide, and their stalk can be 12 inches long! Like most maple leaves they have 5 lobes, meaning that they have five rounded projections extending out from their center, rounded like your ear lobes. This beautiful tree of mammoth leaves also reaches gargantuan heights, especially when exposed to a steady stream of sunlight: it can be up to 160 feet tall at its maximum height. It is the only native maple of the coastal PNW and, with the red alder, it is one of our native hardwood tree species. If its massive leaves are not enough to help you recognize it, look for their fruit, which hangs in elongated clusters, and each one looks like a pair of wings. In the spring, they give yellowish tiny flowers that droop from their twigs. When bigleaf maples are young, their bark is smooth and greenish-brown, and as they reach for the skies, it turns blackish and is deeply ridged, strong and fibrous, which is why the Coast Salish tribes use it to make rope and baskets. We love this colossal maple for its beautiful green leaves in the summer, which can double as an elegant green fan, and its intense yellow fall color that brightens our urban canopy. But we love it most because it lives in community with other local favorites: if you find a bigleaf maple, you’re also likely to find the Doug-fir, western redcedar, western hemlock, the Pacific rhododendron, and salmonberry, among other native trees and shrubs with whom it interacts, benefits from, and gives back to! Cheers to mountainous maples and supportive communities of people and plants!

Douglas Fir | sčəbidac | Pseudotsuga menziesii

Although some of us may only think of Douglas firs when the Christmas season approaches, they are with us year round, and help make Washington the evergreen state. This native conifer thrives in high elevations with moderate summers. In the right conditions, they can grow to be 300 feet tall, and are one of the tallest in the pine family. With all of the evergreens in our city, it can be hard to tell them apart. However, all you have to do is look down! Many times, Douglas firs are so tall you can’t even see their needles! So, the easiest way to identify them is from the cones that have fallen to the ground. They are small cones, about three to four inches in length and look as if there are small mice tails sticking out from underneath the scales. As the Coast Salish story goes, a long time ago there was a large fire in the forests. Many animals were running around frantically trying to escape the flames. The mice ran up the trunks of the trees to the canopy and hid in the cones of Douglas firs to escape the fire. To this day, if you examine a Douglas fir cone, you can see the tails of the mice sticking out between the scales.
Doug-firs drop their cones every year, and their needles have a lifespan of eight years. The trunk develops deep crevasses as the tree matures. It is the tree that moves the most amount of water out of any of our local native trees, which makes them a key species in our ecosystems. There are countless in Point Defiance Park and around Tacoma. Next time you spot a tall evergreen tree surrounded by fir cones, look for the little mice tails of the Douglas fir.
