Mushroom Identification Workshop (FULL)

Friday, May 4
9am-12pm
$15/member, $20/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.

This class is now full. To be added to the wait list, please email info@hoytarboretum.org or call (503) 823-1649.

Introduction to Flowering Plant Identification: The Basics

Wednesday, May 16
9am-12pm
$15/member, $20/non-member

Have you ever wondered how to identify native plants or common weeds? What characteristics should you look for, and how are plants sorted into groups? How are common and scientific names different?

This 3-hour workshop on the basics of plant identification will introduce novices and plant enthusiasts to the wonderful world of plant identification! We will learn about plant parts, leaf shape and arrangements, flower parts, fruit types, etc. and will also examine those key characteristics that place a plant into a certain taxon (named group). We will also have a brief overview of plant classification (naming), examine the notable features of five or six plant families, and introduce participants to a few local field guides that can be used in our region. No prior experience with plant identification is necessary!

We will also take a short walk in the arboretum to further look at plants and plant parts. Wear weather-appropriate clothing, comfortable walking shoes, and bring a small snack and water for our walk.

About the instructor: Dr. Mandy Tu is the Plant Taxonomist & Herbarium Curator at the Hoyt Arboretum. In this position, she is responsible for collecting voucher specimens and verifying the identity of the trees within the arboretum and is often asked to identify plants by natural area managers in the Portland region.

Birding by Ear Workshop

In this class, experienced ear birder Laura Whittemore will introduce you to the songs and calls of some of the common resident and migrant songbirds of the Pacific Northwest. Tune up your ears indoors with a short slide and audio presentation of local songsters, then use your new awareness on a walk around the Arboretum to detect birds by moving slowly, listening carefully, and tracking down mystery singers. Suitable for any birder who wants to start learning the voices of birds.

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.
