May is a vibrant month at the UWBG’s Washington Park Arboretum.  The show that the Olmstead Bros. firm had in mind when they designed Azalea Way back in the 1920′s reaches maximum glory as fading cherry blossoms hand over the reins to innumerable phonograph-shaped blooms that wall the 1/2 mile promenade.  It’s easy to be swept up in the colors and scents of spring, so gaudy and distracting, but there is vibrancy beyond the blooms as well.  The soil has reached a consistent warmth, the night time air has lost its bite and everywhere is teaming with insects.  They’ve timed their reappearance perfectly with the lime-green growth in the park, as have the bats, birds and frogs to eat them.  What better time to hold a bioblitz.

 May 10th/11th marked our third full-on blitz, and our second spring-time one.  (We’re on an 18-month spring/fall cycle).  The inaugural UWBG Bioblitz took place around this same time of year in 2010 and focused on the north end, Foster Island.  Our focus this time was on the middle third of our 230 acres – the heart of our “native matrix”.

The "green zone".

The “green zone”.

Declaring a focal area is pretty arbitrary speaking to birders and mammal trackers – they cover as much territory as their quarry.  For the entomologists I tagged along with during the first taxa team shift on Friday afternoon, however, we’d hardly left the greenhouse before the Siren’s song crashed us on a grove of cedars to pick and dig and shake and catch.  They indulged and in the process trained their few citizen-scientist tagalongs, and then I pried them away to plunk them in the “green zone”, a 200,000 sq. ft. square in the middle third.  We made it through about 1.5 of the 100′ x 100′ grid squares on our map.

The plant team was moving at a similar pace because this year we decided to do something a little different.  The WPA has within it’s collection around 10,400 specimens.  We have information on all of them, information like where they came from, when they were planted, by whom, etc.  Also within the WPA, however, are acres of more or less natural areas, our “native matrix” comprised of big old native trees that regrew from seed after the site was last harvested in 1896.  About these trees, we have very little information.

So for bioblitz, we teamed up with Lisa Ceicko from Forterra to begin an inventory of our native trees using i-Tree protocols.  I-Tree is a program that when you enter in some basic data like tree type, diameter, height, etc., it spits out numbers representing various ecosystem services that a given tree is providing.  King County (also with Lisa’s help) is in the midst of completing their Integrated Urban Forest Assessment aimed to determine how much carbon is being sequestered, air/water  being purified, habitat provided, etc. by Seattle’s trees using the same program.  We aim to do the same with our big old natives.  During Bioblitz, we made it through almost three grid squares…only 592 more to go.

After that first shift it was time for dinner and a lecture with this year’s guest speaker, Paul Bannick.  If you haven’t seen Paul speak, you should, but regardless, you’ve ever opened up a bird book, you’ve probably seen his photographs as his work is featured in all the good ones.  His book, The Owl & the Woodpecker, inspired a traveling exhibit created by the Burke Museum and he’s won a couple really big awards over the past few years, one from Audubon Magazine the other from Canon.  His talk and slideshow focused on owls, and gave those in attendance a glimpse into his next book.  It was both fascinating and beautiful.

Paul Bannick's talk was filled with extraordinary shots like this one.

After the talk, half of the next taxa team shift focused on owls as well, the other half, bats.  There lives within the WPA a pair of resident Barred Owls.  They’ve been seen here consistently for the past several years and they’ve reared several successful broods.  It’s nesting season right now, and we know where they’re nesting.  Despite all this, however, the owl team got skunked.  Not even a “who cooks for you”.  The bat team, on the other hand, led by members from Bats Northwest, fared much better.  With their sonar equipment, they recorded hundreds if not thousands of these misunderstood echo-locators, mostly Silver-haired Bats.  I learned that there are 15 bat species in Washington State, 13 of whom live west of the Cascades.  We fear bats for their blood-sucking reputation, yet only 3 species worldwide actually suck blood, and two of those target birds.  Ironically, without bats, we’d lose countless more blood to mosquitoes.  Bats eat 40% of their body weight in insects per night, and as an added bonus they help pollinate night blooming flowers (such as agave for making tequila).

Saturday started with some early morning bird teams (one by land and one by kayaks provided by Agua Verde Paddle Club), a plant team and a mammal tracking team.  The kayakers were happy to see a Spotted Sandpiper as well as a Pied Billed Grebe nest floating on some lily pads.  The land-lubbers were happy to see the owls.  The tracker, Linda Bittle from the Wilderness Awareness School, was just happy to be out of the office.  The day continued with more of the same plus a couple spider team outings with Rod Crawford and one lonely mushroom team.  Sunny springs can be tough on mushrooms and there were several great events competing for mushroom folk attention – a lecture from local legend Paul Stamets Friday night, and Mushroom Mania at the Burke.  We look forward to another fungus-blitz this fall to give this taxa its deserved attention.  And we look forward to continuing our bioblitz tradition for many years to come.  We hope to see you at the next one, and in the meantime, we’ll be doing what we can from a management perspective to sustain and increase the biodiversity in this gem of the Emerald City.

UWBG Bioblitz 2013 at the Washington Park Arboretum

April 9th, 2013 by Arboretum Education Supervisor, Patrick Mulligan

long_toed_salamanders_Christina_D

A bioblitz is a biological inventory that takes place over a short period of time (usually 24hrs) in a specified area (in this case the Washington Park Arboretum). The purpose of a bioblitz is to take a snap shot of biodiversity, which is a way to measure the health of an ecosystem. The more organisms found, the healthier the ecosystem. We value bioblitzes at the UWBG for a number of reasons: they’re a tool to help us manage our site as sustainably as possible; they’re a great way to engage with our community and raise awareness of the importance of biodiversity (even in urban environments); and since they are hands-on and fast-paced, they are also a lot of fun.

The way it works is there will be 2.5 hour shifts during which small groups of citizen scientists & UW students will go out with one of our field scientists in search of various taxa (birds, bats, bugs, fungi, plants, mammals, etc.). As a team, they try to ID and count what they find and record the location where they found it. In some cases (e.g. fungi, insects) specimens can be collected and identified later.

Space is limited, so click here to sign up for a shift today!

Bioblitz 2011 (debrief)

November 3rd, 2011 by Arboretum Education Supervisor, Patrick Mulligan

Bioblitz 2011 has come and gone, and like last year I find myself still thinking about how awesome it was a week.5 after the fact.  It’s a lot to pull together and 10 days seems about right as far as decompression goes.  I can’t quite put my finger on it, but bioblitzes tap into so many different fibers of my genetic memory.  One of the things that has stuck with me since grad school is Howard Gardener’s multiple intelligence theory.  Gardener considered the standard IQ test limited and proposed 8 different kinds of intelligences to describe the ways people can be smart.  Originally, he only identified 7, but he went back several years later to add “naturalist intelligence” to the mix.  Self-diagnoses suggests I show strong tendencies toward this type, and I dare say many of those who attended UWBG Bioblitz 2011 last weekend express these character traits as well: “would rather be outdoors than in”, check; “can pick objects out of patterns”, check; “knows the names of plants & animals”, check; “observant of surroundings”, check.  All of us can find a little naturalist intelligence in ourselves, evolution wouldn’t have it any other way, but we seldom have golden opportunities to exercise such muscles as a bioblitz presents.

But aside from the obvious appeal to my nature-nerd side, this bioblitz hit me on a human level as well (Gardener’s “interpersonal intelligence”).  At one point on Saturday, I found myself on a mushroom team with a pair of traveling mycologist/photographers from Massachusetts, an energetic immigrant from the former Czechoslovakia, a Serbian visiting from Portland, a UW student from the French Alps, a family of four that included two inquisitive young boys, and the daughter of Fujitaro Kubota, of Kubota Gardens.  What brought this group together on this predictably soggy but clear fall afternoon?  I can’t be sure, but my hunch is that when these people heard about the opportunity to participate in biological inventory of the WPA, it triggered a response from their “naturalist intelligence” and like a moth to a flame could not help but be there.  Either that, or they were bored and in the neighborhood.

The highlight during that particular field session was the discovery of a stinkhorn fungus just off of Azalea Way.  The stinkhorns are a group of fungi that produce a smelly, slimy substance designed to attract flies.  The fly visits the source of the smell (a combination of gym socks and rotting fish), is covered in the spore-laden slime which later dries while the fly is in flight and in this way is dispersed far and wide.  Seed dispersal is a key concept discussed in our Plants 101 & 201 fieldtrips, but when we talk about spore producers like ferns and mosses, we typically teach that surface moisture is the only method of dispersal.  Stinkhorns obviously evolved a different approach every bit as advanced as the seed producers who rely on animals to get around.  I will never again sell these fascinating forest dwellers short, they are anything but primitive.

Other highlights of the event included an illuminating dinner-time presentation from doctoral student, Rachel Mitchell, who spoke of the importance of and threats to biodiversity.  One thing that resonated from Rachel’s talk was the concept of redundancy – a characteristic of healthy ecosystems.  Rachel’s research focuses on meadow habitats where very similar but different grasses fill similar niches and serve similar functions.  Redundancy is an insurance policy that makes an ecosystem more resilient to environmental changes.  A slight change in temperature, for example, may be enough to affect one species of grass but not another, so while one species may crash, the ecosystem as a while continues to function properly.  This concept alone is enough to warrant our efforts to preserve biodiversity in the world.  To paraphrase E.O. Wilson, biodiversity is the fabric that holds the web of life together and when we tear at this fabric we risk having the whole web fall apart.

After the talk, we took to the water in search of the Arboretum’s nocturnal residents.  With help from our fearless leaders from Agua Verde Paddle Club, we paddled around Foster & Marsh Islands in small flotillas.  It didn’t take long to find what we were looking for as the first of many loud smacks echoed across the water.  All told, we accounted for 13 beavers, the bulk of which were hanging out by that funky metallic sculpture on the north side of 520.  The beavers’ tail slappings were punctuated by the occasional pterodactyl-like squawk of Great Blue Herons sent awkwardly skyward by our presence.  I felt a little bad about causing such a raucous and disturbing these and the other shadowy creatures of the marsh with our poking, but then again it’s only once a year.  The “owl-prowl” that followed our aquatic excursion was less eventful – only managing to scare up one brief conversation with a Barred Owl, but it was a lot of fun none the less.  On our way back to the greenhouse, we happened upon 3 of the chubbiest raccoons I’ve ever seen climbing straight up a Douglas Fir near the Visitor’s Center.  These ring-tailed residents have obviously figured out how to take advantage of our numerous trashcans.

The following morning, despite sideways rain at dawn, I was astonished to find a dozen eager birders ready to take the kayaks back out to observe the wetlands in the “daylight”.  They were rewarded for their tenacity with freshly made bagels from Bagel Oasis, and a nice list of birds that you can check out here on ebird.  The remainder of the day was devoted to mushrooms, insects and plants (those lists are still being compiled).  I would be remiss without sending out a big thank you to the Puget Sound Mycological Society for their participation, as well as to all the UWBG staff members who came out to help.  While there weren’t any earth shattering discoveries from the plant teams, it was a great opportunity to a) have a chance to engage with the public, and b) take a close look at our grounds in a non-work capacity.  After all, the mission of the UW Botanic Gardens is Sustaining managed to natural ecosystems and the human spirit through plant research, display, and education.  So not only does Bioblitz strike multiple chords with me personally, but it beautifully supports our reason for being.  We’ve decided to alternate yearly between spring and fall events to capture a more complete picture our biodiversity and avoid over-taxing our pool of specialists, meaning the next UWBG Bioblitz will be held in spring of 2013.  Stay tuned and I hope to see you there.

Bioblitz 2011

September 9th, 2011 by Arboretum Education Supervisor, Patrick Mulligan

 

The UW Botanic Gardens is pleased to announce BIOBLITZ 2011, the 3rd installation of a long-term citizen science experiment aimed at measuring and tracking biodiversity within the Washington Park Arboretum – a 230 acre collection of trees founded in 1934 making it Seattle’s 4th oldest public park.

Bioblitz 2010 was held last May and attended by over 100 volunteers comprised of scientists, both professional and aspiring, of all ages and interests. Approximately 400 species from a variety of taxa groups, including a potentially new species of Philodromus crab spider.

foster island phil1The Fungus Among Us”, a special edition held in partnership with the Puget Sound Mycological Society and focused entirely on mushrooms was held in October, 2010. Close to 80 volunteers collected approximately 500 specimens during four 3-hour shifts.

With these base line numbers, we now have some idea of who is calling the WPA “home”, but these two surveys provide only snapshots of the ever changing story being played out upon this piece of urban green space. In order to gain a deeper understanding of this special place, we strive to duplicate our experiment and turn these snapshots into a movie. Our mission at the UWBG is to “sustain managed to natural ecosystems and the human spirit through plant research, display, and education.” You are invited to help us fulfill that mission by taking part in this unique event.

What: Small field groups surveying various habitats for different taxa groups during six 2.5 hour shifts over a 24 hour period.

When:  October 21 – 22

What time:

Friday, Oct. 21st                                                            Saturday, Oct. 22nd

Foster Island spider appears to be new species

February 16th, 2011 by Jennifer Youngman, Communications Specialist

You may recall that last spring’s BioBlitz in the Washington Park Arboretum resulted in some interesting finds, thanks to the efforts of more than 100 citizen scientists, university students and professionals. Here’s an update on one of those discoveries.

Foster Island Philodromus spiderRod Crawford, Curator of Arachnids at the Burke Museum of Natural History and Culture, reports, “I just finished fully curating the spiders from last May’s Foster Island bioblitz. The unusual Philodromus crab spider from the Waterside Trail, is not P. imbecillus nor is it P. insperatus (only member of the imbecillus group known from Washington). It is very similar to an Atlantic-states species Philodromus marxi, but is more likely to be an altogether new species. Full confirmation will have to await more specimens including males, but we can tentatively consider it new.”

The Foster Island female spider’s reproductive organs don’t match those of Philodromus insperatus, a spider found in this state but mainly in sagebrush country. And the Atlantic states’ P. marxi’s body coloration is metallic, very different from that of the spider found on Foster Island. And so the research continues.

Rod Crawford maintains a website called The Spider Myths Site. Interestingly, two of the myths are “Spiders are easy to identify” and “The spider you found has to be a species you’ve already heard of.”

Bioblitz: Mushroom Edition re-cap

November 5th, 2010 by Arboretum Education Supervisor, Patrick Mulligan

Last spring, the University of Washington Botanic Gardens hosted a bioblitz to take a stab at identifying the myriad organisms for which Washington Park Arboretum is home.  Last week, we continued this effort but with a focus on fungus.  During Bioblitz: Mushroom Edition, Puget Sound Mycological Society members teamed up with over 60 citizen scientists for a full day of mushroom hunting that by sundown netted approximately 500 specimens.

The folks from PSMS had been with us in the spring for the all-taxa bioblitz, and had expressed a desire to come back in the fall during prime mushroom season.  The mushroom people I’ve met in Seattle are like that – deeply passionate, and genuinely enamored with their quarry.  As for the 60 more or less random people that showed up on this predictably drizzle October day, they were almost as diverse as the mushrooms that were collected.  (I say almost because everyone smelled pretty good; the same cannot be said for the mushrooms.)  But what is it about mushrooms that so captures our collective curiosity?  It’s a difficult question to answer because the answer differs depending on who you ask.

I participated in all three of the 2-hour hunts, and attended Marian Maxwell’s presentation on “The Role of Mushrooms in the Ecosystem”, and so I had the chance to mingle with a good number of attendees.  I hunted briefly in the afternoon with Alex, a recent transplant from California where he worked as an environmental educator – a man after my own heart.  Alex likes the way mushrooms force one to slow down and really look at one’s surroundings, even under one’s surroundings.  He used to do this on hikes with kids in California.  I’ve done this with fieldtrip groups at the arboretum, and I can verify the mesmerizing power of fungi.  Alex and I agreed that anything with the power to keep a group of 4th graders captivated for any real span of time borders on miraculous.

That being said, often times kids make the best mushroom hunters.  The Allgood family, with their two young daughters, joined us for much of the day (including the lecture), and contributed dozens of carefully collected specimens to our total.  The Allgoods are avid P-patchers who believe that the healthiest food is the food you grow yourself.   The desire to learn more about a potentially free, natural and local food source is what brought them out.

With the “eat local” movement gaining momentum and food security conversations becoming household, being able to forage for ones food is in vogue and mushrooms are poster children, and why not.  They’re abundant, extremely varied, the right ones are delicious, and you’re simply harvesting a fruit much like any other (but without the maintenance), so there’s no harm done. The trick of course is finding the right ones.

The edibility and lure of foraging for ones food was a common tie among many who came out.  Colin, a UW freshman only months into his college experience, is already tiring of “dorm food”.  While the Arboretum cannot be considered a place to go harvesting ‘shaggy parasols’ (it’s illegal to take anything out of this Seattle treasure), Colin was very pleased to rescue the handful we collected from their immanent fate in the compost pile and eager to get out into the mountains to find his own secret spot.

That’s what my wife likes about mushroom hunting – the hunting part.  The idea of going home with something tasty to eat is secondary to the thrill of the hunt.  Having a mission to focus on helps to quiet her ADD brain and allows for a much more enjoyable hike with a husband who is perfectly happy wandering aimlessly through the woods.  This example speaks to an indirect medicinal property that mushrooms hold, but there are some mushrooms such as the Agarikon (Fomitopsis officinalis), which only grows on old growth, that are being researched by pharmaceutical companies for their anti-viral, anti-fungal, anti-bacterial, and possibly anti-cancer properties.

Of course there are others who are less interested in the potential for mushrooms to heal the body and more interested in the potential for mushrooms to heal the mind.  David, who I met during the morning hunt, though “out there” by conventional standards, is a deeply spiritual man who loves everything about mushrooms, including the ability of some to alter reality.  The hallucinogenic properties of mushrooms are well known and well documented in cultures around the world.  In many of these cultures, only the most revered members of the society – the shamans, medicine men and mystics are allowed to meddle with these powerful substances.  After all, these seemingly innocuous forest dwellers can kill you and every year even experienced mycologists die from eating mushrooms they believed to be safe.

Marian touched on the toxicology of some mushrooms during her talk, describing it as a self-defense mechanism and a way for one mushroom species to stake out turf over another.  Often times, but not always, these mushrooms with toxic properties are categorized as parasites – the potentially harmful group that steals nutrients from host plants weakening and eventually killing them.  Unfortunately, an example of this group, the Honey Mushroom (Armillaria mellea), was found living on some of our trees.  But that’s part of why we do these bioblitzes, to better know our 230 acres and how to manage them.

Marian also talked about a group of mushrooms called symbionts.  These are mutualists that actually benefit their associated host.  Examples include some of the more highly sought after mushrooms such as chanterelles and truffles.  This group is extremely difficult to cultivate because the symbiotic relationship between tree and mushroom takes several decades to form.  Once formed, however, the mushroom benefits by obtaining some of the sugars produced by the tree, and the tree benefits because the intricate mycelial network inhabiting the root zone greatly expands the trees ability to take in water and nutrients (as well as fight off potentially harmful diseases).

I envision roots wrapped in wooly sweaters wicking in the good stuff and keeping out the bad.  The really cool part is that specific mushrooms are associated with specific trees, and so once the relationship is established you can go back to the same tree year after year and expect to find the same type of mushroom.  This is dependent of course on time of year, weather conditions, and assuming you’ve gotten there first!  I think this is what I really like about mushrooms – they so beautifully illustrate the interconnected nature of nature.  If you know the tree you’re looking at, you’ll know what mushroom to look for, and maybe even what kind of bird or other critter to expect nearby.  A balanced forest ecosystem is like a well choreographed dance, each dance playing an indispensible role and strengthening the overall composition.

The third group of mushrooms that Marian talked about was the saprophytes.  These are the forest recyclers that obtain their nutrients by breaking down decaying matter.  By doing so, these nutrients are made available to be taken up and used again.  This group was by far the best represented of what we found owing to the time of year and abundance of decaying matter (fallen leaves and mulch).  Because of this, there are already murmurs among our PSMS partners to come again next year, but a little earlier in the season in hopes of finding different species.  So stay tuned, and regardless of what it is about mushrooms that tickles your fancy, come join us next time and take part in this ongoing citizen science experiment to see what we can find living in this wonderland of urban nature that is the Washington Park Arboretum.

The Fungus Among US

October 1st, 2010 by Arboretum Education Supervisor, Patrick Mulligan

mushroom graphicThis past spring, the UWBG hosted the first ever bioblitz in Seattle.  A “bioblitz” is a biological scavenger hunt that aims to inventory all the various organisms living in a given area – the “blitz” part signifies that this inventory is taken within a short period of time.

There are several reasons why the UWBG aims to make bioblitzes a regularly occurring tradition:

  1. to better fulfill our mission of sustaining managed to natural ecosystems
  2. to raise awareness of the importance of biodiversity in an urban environment
  3. to bridge the gap between the academic world and the every-day world by harnessing the power of citizen scientists.

During our first attempt, close to 400 different species of plants, birds, insects, spiders, lichens, mammals, reptiles and fungi were accounted for in the Washington Park Arboretum, a major branch of the UWBG.  Several groups predicted that that number would have been higher had the bioblitz taken place during a different time of year.  The fungi group, comprised primarily of Puget Sound Mycological Society members, was among the groups itching to come back during more suitable conditions (i.e. fall).

And so, the UWBG, in partnership with PSMS, and with support from the Arboretum Foundation gives you, Bioblitz:  Mushroom Edition, “The Fungus Among Us”.

  • When: Thursday, October, 28th
  • What time: 10am – 10pm; with 3 scheduled hunts & a public presentation from PSMS President, Marian Maxwell.
    • 10:15am – 12:30pm
    • 1:15pm – 3:00pm
    • 3:15pm – 5:30pm
    • Public Lecture: 6:30 – 7:30pm: “Mushroom Ecology” by Mariam Maxwell, PSMS President
  • Where: The Washington Park Arboretum, Graham Visitors Center
  • Who: Anyone & everyone, no experience necessary
  • Cost: Free

BioBlitz reveals potentially rare stinging ant, mushroom, spider & possible new plant invaders

May 29th, 2010 by Jennifer Youngman, Communications Specialist

With more than 100 citizen scientists, university students and professionals scrutinizing Washington Park Arboretum’s nooks and crannies during Seattle’s first BioBlitz, there were bound to be a few surprises. A potentially rare native stinging ant, a potentially rare Amanita (mushroom) not often seen on the west coast, a potentially new species of spider and a couple of unexpected plants displaying suspicious behavior are just a few of the discoveries. Plus, a spider that is regionally rare appears to be common on Foster Island.

The inventory of the Arboretum’s birds, bats, lichens, fungi, reptiles, amphibians and plants (not counting the Arboretum’s plant collection, which is already documented) started at 3:00 PM May 21 and lasted 24 hours, including night-time shifts for cataloguing nocturnal life. One nocturnal lesson: participants collected regurgitated barred owl pellets, dissolved all of the material but bones, and identified bones and skulls to determine that the Arboretum’s owls dine primarily on Norway rats.

BioBlitz plants & animals mapped using handheld devicesThe après-BioBlitz is now in session. Data is being processed. Plant and invertebrate identification continues. Rare species are being confirmed. And plants such as Lonicera periclymenum, an ornamental Eurasian vine not known to be invasive here but found scrambling over plants, will be investigated to see whether they are potential new invaders in this region.

BioBlitzes have served as vehicles for biodiversity data collection for several years in locations ranging from the Nisqually Delta to Cape Cod and New York City’s Central Park. Seattle’s BioBlitz will be useful in establishing baseline data before the Highway 520 bridge project gets underway. Dr. Sarah Reichard, professor and co-associate director of the UW Botanic Gardens, worked with the Washington NatureMapping Program to organize this major undertaking, and the Arboretum Foundation funded it. Although insects were underrepresented due to cold weather and no bats were netted, more than 400 species of plants, animals, lichens and fungi were recorded. View the species tally to date and a list of predicted vs. observed birds, amphibians, reptiles and mammals.

Check out the photo gallery accompanying this Seattle Times article. Thank you to all who contributed time, effort, expertise and enthusiasm to the BioBlitz.
