Wildlife Tracking

Saturday, January 27
9am-12 pm
$15/member, $20/non-member

Portland's parks and natural areas are home to many different kinds of wildlife. Many animals are hard to see directly, but you can know about their presence through the tracks and sign they leave behind. In this class you will learn the basics of wildlife tracking and will explore Hoyt Arboretum to see what mammals have been living here.

About the instructor: Teri Lysak has been teaching wildlife tracking and wild plant foraging for over 10 years, and runs a citizen science project for Cascadia Wild searching for rare mammals on Mt Hood. Previously she worked as a forester, and holds an MS in Forest Ecology from OSU.

Project BudBurst -- Volunteer Training

Thursday, February 8, 10-11am

Project BudBurst is a nationwide, citizen science-driven effort designed to study plant responses to changes in climate. Volunteers are needed to monitor the timing of specific events in a plant's life history known as phenophases (E.g., full bloom, fruiting, etc.) and report their observations to Project BudBurst.

The next training session the Project BudBurst program is scheduled for Thursday, February 8 from 10-11am. During this training, volunteers will learn about plant structures and phenology and choose a specific plant to monitor at Hoyt Arboretum. You can read about our work with Project BudBurst last year in our December 2017 E-Newsletter, and more information about this nationwide project is at http://www.budburst.org/. For more information or to sign up for the training, please email volunteer@hoytarboretum.org or call (503) 823-1649.

Birding 101

Saturday, March 3
9am-12 pm
$15/member, $20/non-member

Birds are everywhere you look, but how to figure out which one is which? This workshop takes the mystery out of bird observation and identification by giving you the tools to see the whole bird—not just its color, but its shape, size, pattern, behavior, and more.

In this class, longtime birder and teacher Laura Whittemore will introduce you to the questions you should ask when faced with a mystery bird. During a slide presentation of local common species, you'll learn to see beyond a bird's color and consider other physical and behavioral characteristics that will tell you about a bird's identity and life history. Use your new awareness on a walk around Hoyt Arboretum as you learn to detect birds by moving slowly, being patient, and using your ears and eyes.

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.

Mushroom Identification Workshop

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.

Limited to 15 people. Registration is required. Please sign up via Paypal below, or call (503) 823-1649.
