Autumn Berries

IMG_0598 (1024x765)

This week some genuinely cold temperatures are (finally) arriving in Walla Walla, but before they did, we took a walk in the Fort Walla Walla Natural Area, a patch of woods in a park a few miles from our house. What caught my eye was all the berries ripening on the shrubs along the trail, which are excellent fall and winter food for the birds in the area as well as looking pretty. I didn’t have the forethought to bring a nice camera, so all the photos in the post were taken with Evan’s and my iPhones, but they turned out okay enough to show you what we were seeing.


I’m Back, and I Come Bearing Purple Death Flowers

I’m baaaaack. My goal is going to be one post a week through the end of the summer. For my first post back from hiatus, I have something special for y’all: giant purple alien flowers that smell like rotting flesh!

While moving my stuff into the house in Walla Walla (yep, no more rural Oregon), I noticed the unmistakable smell of death. Some small animal had clearly crawled into the bushes, died, and was decomposing. We poked around a bit but couldn’t find the culprit so we didn’t think much more about it for the time being.

Not until the next day did we make the connection between the smell and the enormous alien flowers that were blooming in the yard.

DSC_0026 (681x1024)These things are wild. We’d been watching them grow all spring without being sure what they were; they started as tentacle-like spikes sprouting from the ground, then developed the pretty green-and-white striped foliage you can see in the picture, and finally grew enormous two-foot-long buds like alien pod things.

Then the buds opened into spectacular, death-scented flowers.

Turns out that this plant, Dracunculus vulgaris, is native to the Balkans and has variety of expressive common names like Voodoo Lily and Black Dragon. It is (of course) pollinated by flies, which it attracts by mimicking the color and smell of a rotting corpse. In fact, there was a cloud of flies buzzing around the flowers when I was taking photos, although I had trouble getting one in focus.

DSC_0027 (1024x768)The first spring in a new house, when you don’t really know what sort of plants are in the landscaping and every new thing that sprouts is a mystery to solve, is a lot of fun. According to the internet, the rotting flesh smell of our Voodoo Lilies should only last a couple days. We like our weird purple alien death flowers and can’t wait to see what strange thing appears in our garden next.




One Very Big Tree

I spent Wednesday through Friday of last week canoeing the Willamette River over on the coastal side of the state (for work – yes, be jealous). Marked on the map of one of the state parks we camped at, Willamette Mission, was the nation’s largest black cottonwood tree. Who could possibly resist?

It was…

…a very…

IMG_3554 (768x1024)

…big tree.

IMG_3555 (768x1024)

This is the “Willamette Mission Cottonwood,” which is 155 feet tall, has a circumference of over 26 feet, and is approximately 270 years old. For scale, here’s a poorly-lit shot with a couple people standing next to the trunk:

I wish I’d had more time to take better pictures and enjoy it properly, but alas, we were only passing by. Still, it’s always fun to encounter a giant.

A Walk in an Aspen Stand

005 (1024x685)

Back in Wisconsin, aspen suckers grew like weeds after an area was logged. It came as a surprise to learn, when I moved out West, that here aspens are in serious decline and the focus of conservation efforts. Above is a stand that we’re going to be building a fence around soon at work, to protect it from damage from cattle, deer, and elk.

007 (675x1024)

It’s doubtful that elk actually spend much time in this pasture anymore (though they’re definitely around in the hills), but the dark scars on the trunks of the trees come from elk scraping at the bark with their teeth to get at the nutritious, photosynthetic layer of bark under the white outer layer.

009 (1024x685)

While aspen trees do produce flowers, most of their reproduction is vegetative, in the form of new shoots or “suckers” growing from existing root systems. Young, tender suckers are super tasty food for deer – the ones in the photo above, growing in the shelter of a fallen adult, have been heavily browsed. Fencing the deer out of the stand will help young trees get established.

008 (1024x677)

The way suckering works is actually pretty interesting – the crown of the tree produces a hormone called auxin that inhibits the production of suckers. When the tree falls and auxin is no longer produced, the growth of new suckers increases in response to keep the stand going. An aspen stand is really one big organism, interconnected by the root system that keeps on living even as individual trees die and are replaced. One particular aspen clone in Utah is a candidate for the world’s largest, oldest organism.

There are multiple reasons for aspen decline in the West, including the removal of top predators from ecosystems (no wolves -> more elk and deer -> more browsing of aspen) and the suppression of natural wildfires, which allows other trees like junipers to become established and crowd out aspen. Climate change is almost certainly playing a role, as well. More information:


Mount Hood Greenery (and Red-ery and Blue-ery)

The forests of the Cascades are pretty different from ours out here in the arid east – I saw lots of hemlocks and cedars while at Mount Hood, which was a nice change of pace. I also made the acquaintance of some interesting understory plants. First, Pacific Rhododendron (Rhododendron macrophyllum):

Earlier in the season these shiny green leaves would have been complemented by clusters of big, showy pink flowers, but by this time of year all that remained of those was the developing fruits.

017 (1024x770)

Second, ripe huckleberries of both the blue and red varieties – yum! These are two different species in the genus Vaccinium, which also includes blueberries and cranberries.

Nothing beats being able to stuff your face as you walk down a trail, amiright?


Fire and Fireweed

IMG_3470 (1024x767)

This is what the “forest” I was in for work yesterday looked like. One of the teenagers I was with asked me why someone didn’t just cut down all the standing dead trees, and I explained that snags like this are actually important habitat for wildlife such as woodpeckers. It does look pretty bleak, but even on a hot, dry, dusty August day, there were splashes of color.

IMG_3473 (768x1024)

That layer of purple is the aptly-named Fireweed (Chamerion angustifolium). It’s a “weed” because it’s a pioneer species, quickly colonizing disturbed habitat – especially (as in this case) burned-over forest, but I also saw it growing along roadsides back in Wisconsin. However, unlike a lot of weedy, fast-growing roadside plants, this is a native species. This is one beautiful, welcome weed.


In the natural order of things, the trees that re-grow after a fire (you can see plenty of baby trees in the first two photos if you look) will soon out-compete the sun-loving pioneer weeds. Everything has its place and time, and even a bleak-looking forest of charred tree trunks is full of life.


Nobody Likes Junipers

008 (1024x685)

Juniper trees are the nemesis of many ranchers around here. As a result of the region’s altered fire regime – no more wildfires sweeping through and keeping trees from establishing themselves – Western Junipers (Juniperus occidentalis – I like literal Latin names like this) are encroaching more and more onto rangeland, sucking up water with their taproots and outcompeting understory plants.

030 (1024x685)

But the truth is, I kind of like ’em, these tough, scrubby little trees. They’re survivors. And they’re not an exotic invasive species – they were always here, it’s just that now there are even more of them, in more places.

014 (1024x685)

The female cones don’t look like cones at all, but like fleshy little silvery-blue berries. They’re an important food source for fruit-eating birds like robins and waxwings. They’re also where the flavoring in gin comes from. Someone I met at a conference recently told a story about mistaking a bag of juniper berries her boyfriend had left in their freezer for blueberries and baking them into a pie, but I wouldn’t recommend trying that at home.

005 (1024x685)

The rugged individuals of the tree world. Really, they fit right in around here. And since me secretly liking them won’t actually change whether efforts to eradicate them from rangeland are successful, I’m going to go right on doing it.


The Butterscotch Tree

Across large areas of the American West, one tree is the undisputed king of dry montane forests: the Ponderosa Pine, Pinus ponderosa. “Ponderosa” is literally Spanish for “ponderous,” a name which reflects the size and majesty of these trees. However, it isn’t only their beauty (or their value as timber) that makes me fond of Ponderosas. It’s their scent.

Deerhorn, Deer Horns

Two photos to start out your week, both taken at Bridge Creek Wildlife Area last Thursday. First, Clarkia pulchella, a wildflower first discovered by Lewis and Clark. It has several common names, but my favorite one, which comes from the branching petals, is deerhorn.

Second, a deer with horns.

Happy Monday.


Wildflower Photo Dump

Here, have some wildflower photos that I like too much not to post somewhere but that aren’t ever going to get individual blog posts of their own. I particularly like the one of the Mariposa Lily, for which I contorted myself into a knot on the ground to get a good angle.
