How to Preserve Marine Algae

During a recent behind-the-scenes tour of the Burke Museum Herbarium, the museum’s curator of botany Richard Olmstead and herbarium collections manager David Giblin told me about the collections, research and scientific contributions from their collection. One thing that stood out to me is that preservation of plant specimens is a delicate art. In the video below, Richard discusses the methods used to preserve marine algae. The process results in beautiful scientific specimens that can be studied for countless years to come.

A Visit to the Herbarium

If you follow the Burke Museum’s blog regularly, you probably read the recent blog about my trip to the Burke’s Fisheries collection. Last week, I went on another behind the scenes tour to the Burke’s Herbarium.

The Herbarium has approximately 625,000 specimens that range from vascular plants, lichen, algae, mosses and fungi. The Burke Museum’s Herbarium has a primary focus of the flora of the Pacific Northwest. An average of 700 people from all over the world visit the Herbarium each year to access its unique collections, and the research involving these specimens can help answer important questions that affect us all.

What are a few of the many ways we can learn from herbia specimens? Burke Curator of Botany Richard Olmstead and Herbarium Collections Manager David Giblin analyze specimens collected over time to compare changes in floral life from natural disasters, human impact and climate change. From 2005 – 2009, David led a series of botanical surveys (i.e. collecting trips) in the San Juan Islands to create a baseline understanding of the plant diversity found on small islands throughout the archipelago. Plant life in coastal areas may be severely impacted under various climate change scenarios, and the findings from these trips can serve as a benchmark against which future changes can be compared.

David’s team of students, volunteers and fellow scientists visited approximately 90 islands in the San Juans, and one of the highlights was the discovering a previously undescribed species of paintbrush. The years of hard work from Burke Museum staff and community members can help future generations address the world’s changing environments."

The Burke Museum partners with many different organizations to conduct these collecting trips. Here is a key to the different colors of thumbtack that represent these different types of forays:

-White: National Park Service forays
-Blue: Cedar River Watershed forays

How to beat the heat: have a weeding party!

A weeding party to "beat the heat"? Doesn't that seem counter productive? No, as it turns out, not when it is 97 degrees outside, your offices are not air-conditioned, and the weeding can be done in the shade. This week Seattle has been having nearly record-breaking heat, but that didn't stop about a dozen Burke staff and board members from getting down and dirty in the Erna Gunther Ethnobotanical Garden for a weeding party. We made quite a lot of progress and actually had some fun in the process. The garden looks so much better now!

Burke collections enhanced by community support

Posted by: Karin Hoffman, Communications

Are you a lover of Washington plants and lichens? Do you love to take pictures? Do you love taking pictures of plants? If you answered yes to any of these questions, then check out this fabulous Burke herbarium Web site where you can contribute your own photos and share botanical knowledge with the world!

The Burke Museum’s WTU Image Collection Web site is truly a resource that has been built by the community. According to Richard Olmstead, curator of botany at the Burke Museum, “this kind of access enhances the value of our collections and gets the public involved in a way that is different from most of our other outreach efforts.”

Thanks to all who have contributed to the Web-based herbarium collection at the Burke! And a special thanks to David Giblin, herbarium collections manager and Ben Legler for creating an open forum for community participation.

Spring is seen as a time of renewal and growth. Robins singing at dawn, the green tips of tulips emerging from the soil, and apple blossoms are just a few of my favorite indicators of spring. As is usually the case in the Pacific Northwest, this week spring made a brief appearance before hiding behind the gray skies and April showers we are more accustomed to. I made sure to take advantage of this weather treat (and absorb some much needed vitamin D) and headed outside to see spring in action.

I immediately wished I had brought a plant guide book with me. I found myself wanting to know the names of plants with beautiful drooping magenta flowers and delicate yellow flowers. Although one plant that I was able to identify, thanks to its’ distinctive smell, was skunk cabbage. So everyone get out there and enjoy spring and don’t forget your favorite plant guide book. You never know what you’ll run into!

Also, over the next few weeks make sure to check out the cherry tree blossoms located in the Quad of UW’s Seattle campus. AMAZING!

There are a number of helpful guides out there (I find Plants of the Pacific Northwest Coast very useful) and make sure to check out the Burke’s Herbarium division which has a number of great resources.

A new view of the Olympic Sculpture Park

Posted by: May Evans


Sculpture Park also showcases natural beauty of the Northwest…

If you've visited the newly-opened Olympic Sculpture Park, did you notice the "land art"? Besides the eye-popping sculptures, landscape designers have created a display of the Northwest's natural flora and fauna within the Park. To display different ecosystems, the Park was divided into four zones: valley, meadow, grove, and shore. Each zone contains the plants which naturally grow in these areas in the Northwest.

The valley zone was designed to represent the lowland coastal regions. It was planted with trees such as fir, hemlock, cedar, ginkgo, and redwood, with flowering perrenials, ferns, and other groundcovers.

The meadow zone includes three large meadows which together form a kind of natural "fenceless" park. This area was planted with wildflowers and grasses that will only be cut once a year. In this zone you will find crimson columbine, pearly everlasting, and camas lily flowers.

The grove is a forest of over 180 aspens with a meandering walking trail. This zone defines the transition from city to shore, and also features the flowering currant, wood rose, and Oregon iris.

The shore, of course, runs along the waterfront, and features common Puget Sound coastal plants, including dune grass, and nootka rose. However, the landscapers didn't stop at the shoreline. SAM wanted to restore the shoreline to its original state, and that meant extending their efforts into Puget Sound, creating a habitat bench of rocks and native underwater plants. This habitat restoration aims to bring salmon to the Sculpture Park and to highlight the uniqueness of Puget Sound's coastline. SAM is also partnering with Seattle Public Utilities in a five year beach-restoration monitoring program on this site.

So the next time you visit the Olympic Sculpture Park, notice the natural beauty beneath your feet, over your head, and below the water. Artists aren't the only ones who can create a large work of beauty.

Cherry Blossoms and Global Warming

Posted by: Karyn Gregory


Sakura is the Japanese name for cherry blossom trees, a popular landscape decoration here in Seattle. The trees on the University of Washington campus have begun to bloom, an annual event anticipated by many locally.

In their native country, millions of yen are poured into festivals and parties to watch the trees bloom and celebrate nature’s beauty. It’s a magnet for tourism and people plan their trips well in advance based on blooming predictions from the Japanese Meteorological Agency.

This year the Agency predicted that global warming would cause the trees to bloom a full 10 days earlier than in years past, setting a new record.

Unfortunately, these predictions were found to be false, made in error due to a computer bug in their system. Oops! The Agency has spent the past day apologizing for any inconvenience their inaccurate predictions may have caused. They now predict that the trees will bloom next Wednesday, March 21.

If you’re not heading off to Japan, there’s always the Seattle Cherry Blossom and Japanese Festival, planned for April 20-22, 2007. This year there will be a symposium on “Japanese Design Today” and a performance by Japanese heavy metal band BlesseDmain.
