Certainly teaching is an exciting way to learn, and Diane has been an instructor at SW Community Center, PCC Community Education, and Lan Su Chinese garden. She emphasizes balance, posture, and mindfulness in her tai chi classes—and the fun and relaxation of movement. As a “senior,” Diane understands the challenges that aging brings.

Forest Birds Workshop

Saturday, September 15
9am-12pm
$15/HAF member, $20/non-member

Mature Pacific Northwest forests host birds that are uniquely adapted to live in different layers of the forest. This workshop will teach you which birds to expect in our coniferous, deciduous, and mixed forests, how to detect them by sight and sound, and which adaptations help them survive and thrive.

In this class, experienced birder Laura Whittemore will introduce you to the common birds of Pacific Northwest mature forests, such as kinglets, creepers, nuthatches, woodpeckers, and owls. Learn how to find and recognize these sometimes elusive species using location, behavior, plumage, and sound. We'll start with an indoor presentation, then you'll use your new awareness on a walk through the Arboretum to detect birds by moving slowly, listening carefully, and paying attention to habitat.

About the instructor: Longtime birder and teacher Laura Whittemore loves to show beginners the tricks of the trade. She regularly teaches classes for Audubon Society of Portland and previously worked for Backyard Bird Shop, where she helped bird-feeding enthusiasts ID those confusing little brown birds. Laura holds a BA in Biology from Lewis and Clark College and has traveled in the US, Australia, South Africa, and Antarctica in search of birds.

Fall Mushroom Identification Workshop

Saturday, September 29
12-4pm
$20/member, $25/non-member

The Pacific Northwest is home to a wealth of fascinating fungi. If you've ever been curious about how to identify the mushrooms you see, here is your chance!

In this class, mushroom enthusiast and avid forager Leah Bendlin will teach the basics of mushroom identification, from key physical features, to habitat and ecological roles. Bring in your own finds for guided practice applying ID processes following the presentation. We will also take a hike in the arboretum to find mushrooms in their natural habitats.

About the instructor: Leah grew up in the midwest with nature loving biologist parents who taught her how to forage for edible plants. Later, she moved to the Pacific Northwest, and a friend took her out one day for a chanterelle hunt. She was fascinated not only by the bounty of chanterelles that year, but also by the abundance of other mushrooms that she had somehow never noticed before. After asking friends more about mushroom identification and coming up with dead ends, she set out to teach herself. A chance encounter soon became a life passion. Leah became obsessed with mushroom taxonomy and all the facets that go into the hunt, learning to read the land for signs of treasure. In 2015, she was elected to the board of directors of the Oregon Mycological Society, where she currently also serves as a teacher, speaker and identifier. After seven years of intense study, she now takes every opportunity possible to share the love of fungi with others and inspire them to begin their own journeys.
