Native Plant Keying Workshop

Date: Saturday the 22nd

Time: 9:00am – 4:00pm, with an hour for lunch

Location: Reed College, Biology Building

Leader: Brent Miller

Description: Botanical keys can be very daunting. This one-day class will teach you how to use a key to identify live or pressed plants. The first part of the day will be with plants in a classroom, learning how to read a key and getting familiar with basic technical vocabulary. The class will be highly interactive, to get you the knowledge you need to improve your keying skills. Later, you’ll take your knowledge into the field, bringing your flora with you and keying out plants in their native habitats. Fee of $10 to cover materials. Bring a copy of Hitchcock & Cronquist’s Flora of the Pacific Northwest if you have one. Please register by emailing You will receive more detailed information about the workshop when your spot is reserved. 

Field Trip: The Great Camas Scotch Broom Pull

Date: Sunday, April 23rd

Time: 9:30am – 11:30am

Location: Great Camas Patch, Carson, WA

Leader: Roger Brewer

Description: Over the last few years we have made excellent progress toward control of Scotch Broom on this piece of property near Carson, WA that Russ Jolley loved and cared for. At this work party we will be looking for and eliminating new sprouts and removing plants we might have missed last time. We’ll have saws and loppers. It may be helpful but not necessary for to bring yours also. Please bring gloves and clippers. We will work for about 1.5 hours, from about 9:30 to 11:00-11:30, followed by a quick lunch, and for those who are interested, a hike at nearby Lost Creek (see the next listing!). Those who don’t want to join the Lost Creek hike may do a short botany trip in the area before car-pooling back to Portland. Please contact Roger Brewer at to find out where and when we will meet to form car pools.

Field Trip: Giant Trees of Lost Creek Hike

Date: Sunday, April 23rd

Time: After the Scotch Broom Pull

Location: Lost Creek, Carson, WA

Leader: Susan Saul

Description: The price of admission to the Giant Trees of Lost Creek is a morning stint of Scotch Broom pulling at the Great Camas Patch (see above listing!). Reward your labors with a hike underneath the ancient Douglas-fir and western red-cedar trees of Lost Creek. In the late 1990s, the late Russ Jolley helped save the 170 acres of big, old trees from a timber sale and this place was dear to him. The hike will be on an unofficial path forming a fairly easy 1.5 mile loop. Expect to walk across streams on logs and climb over or around fallen trees. We will leave from the Great Camas Patch following the Scotch Broom Pull, so there will not be a departure from Portland. Bring water, snacks, hiking boots and warm jackets and hats — it will be cool underneath the big trees. Contact Susan Saul for more information at

Take a peek at the seeds of a multitude of Oregon plant species under the stereo microscope. Watch a slideshow of some of our rarest and loveliest plant species. Enjoy some evening nibbles. Find out about our new community science program, Citizen’s Rare Plant Watch, which was originally founded by NPSO volunteers, and is dependent on dedicated volunteers for its existence. A kind of serious treasure hunt for rare plant populations, CRPW provides crucial support to public agencies across the state that are tasked with preserving our natural riches. We’ll tell you what we’ve done and what we’ve learned so far, and about upcoming opportunities to explore Oregon lands while serving your northwest community.

Paddle and Plant Walk at Elk Rock Island – FULL

Date: Tuesday, April 25th

Time: 4:30pm – 8:00pm

Location: Elk Rock Island

Leader: Mary Bushman (City of Portland) and Marci Krass (Willamette Riverkeeper)

Description: Elk Rock Island is located on the Willamette River just offshore from the City of Milwaukie boat ramp just south of Portland (about 20 minutes south of the Hawthorne Bridge). Elk Rock Island is owned and managed by Portland Parks and Recreation. If you love to explore the flora and fauna of oak and prairie habitats (Saxifraga occidentallis, Lomatium triternatum, Fritillaria affinis, Piperia elegans, Plagiobothrys figuratus, Gratiola ebracteata), Elk Rock Island is a great place for those explorations. Vernal pools on the island are particularly interesting. City staff has been monitoring unique plants, water quality, and critters in the vernal pools. On this boat trip you will experience the thirteen acre island from the water and on foot. Registration is required due to the limited number of canoes.

Willamette Riverkeeper will be providing use of canoes, PFD’s and paddle free of charge.  No paddling experience is necessary. If you have your own boat and plan to bring it along please let us know when you register.

NPSO Field Trip: Camassia Preserve

Date: Wednesday, April 26

Time: 5:30pm – 7:30pm

Location: Camassia Preserve, 5000 Walnut Street, West Linn, OR 97068 (map)

Leader: Jason Clinch

Description: Easy one-mile hike through a Nature Conservancy preserve named for the common camas (Camassia quamash) which profusely blooms here in April and early May. This preserve hosts more than 300 plant species. The rocky plateau was exposed 12,000-19,000 years ago when the Bretz Floods or Missoula Floods poured down the present Columbia River Gorge and far into the Willamette Valley. The floods swept soil and vegetation from parts of the valley and deposited granitic boulders (called “glacial erratics”) from as far away as Canada.

This hike is limited to 12 people and parking is very limited so please carpool. Reserve your spot by emailing Jason at Meet us at the entrance at 5000 Walnut Street, West Linn, OR 97068. The preserve is small so you may be able to still join the group if running late.

Presentation: Lilla & John Leach – Botanical Explorers

Date: Wednesday, April 26

Time: 5:00pm – 6:15pm

Location: Manor House at the Leach Botanical Garden

Description: Join us for a slideshow presentation of the life, botanical explorations, and plant discoveries of Lilla and John Leach. Come before the presentation starts to explore the Leach Botanical Garden; NPAW is a great time of year to see a diversity of flowers in bloom at the garden!

The lower parking lot will be kept open during the event. Please note that the 122nd Ave bridge is closed to car traffic; the attached map of alternate driving routes to the parking lot is also available on

Native Plants and Pollinators of Mt. Hood

Leader: David Lebo

Description: Bark will be co-sponsoring this event with the Portland Chapter of the Native Plant Society of Oregon (NPSO-PDX) to explore the expansive world of the pollinators and their plants. Pollinators are responsible for assisting over 80% of the world’s flowering plants. Without them, humans and wildlife wouldn’t have much to eat or look at! Animals that assist plants in their reproduction as pollinators include species of ants, bats, bees, beetles, birds, butterflies, flies, moths, and wasps. This event will include a presentation by David Lebo, Lead Botanist for the Mt. Hood National Forest, who is collaborating on a project with Bark and NPSO-PDX for the collection of seeds of plants which promote pollinators in our backyard forest. Come learn about what types of habitats and plant species these important creatures need to continue to function within their critical roles. Then learn how to get involved with Bark’s upcoming work to restore pollinator habitat on Mt. Hood! Call us at 503-331-0374 or email at to reserve your spot.

Conboy Lake National Wildlife Refuge 

– Canceled Due to Late Spring Flowering

Date: Saturday, April 29th

Time: 8:30am

Location: Gateway Transit Center (meeting point)

Leaders: Ron Klump and Don Hardin

Description: There is a wealth of native plant attractions on the other side of the Columbia River in Washington, and they too celebrate Native Plant Appreciation Week. Ron Klump, the field-trip coordinator for the Portland Chapter of the Native Plant Society of Oregon, is teaming up with Don Hardin, the President of the Suksdorfia Chapter of the Washington Native Plant Society, who is quite knowledgeable of the plants found in his area. Conboy Lake NWR is one of his favorite places to botanize. There are over 70 species of plants, many of which will be flowering during NPAW. You’ll see some eastern species that don’t range closer to Portland, and many you might be familiar with, like the coralroot orchid or Corallorhiza.

We will be taking the Willard Springs Foot Trail, a 3.8-mile easy loop along the edge of the open marsh and into the pines, stopping often to observe plants. Beginning at the refuge headquarters, it parallels the west shore of the old Conboy Lake lakebed, with views across the lakebed and north to Mount Adams.

*Hike limited to 16 participants* Register by contacting Ron Klump at For further hike details contact Don Hardin at

Oregon’s Garden: Artist Reception at the AC Hotel

Date: Saturday, April 29th

Time: 4:00-6:00pm

Location: AC Hotel, 888 SW 3rd Ave. (corner of SW 3rd and Taylor)

Description: Portland artist David Cohen was one of dozens of artists included in the development of one of Portland’s newest hotels, the AC Hotel. The goal of including art was about trying to create a sense of place – a space that was specifically about Portland and the Pacific Northwest. David’s work is entitled Oregon’s Garden and features Oregon native plants to tell the story of our strong connection to nature and place. We invite you to a no host reception to see this unique work situated in the lobby of the building and hear a few words from David about the piece, his work, and his interest in the natural world.
