Thank you Stream Team 2017!

Over the last few days we had an intrepid team of 10 volunteers join our stream team, rearrange their schedules to beat the oncoming rains, and conduct our 5th annual stream invertebrate survey of Vashon creeks. We finished exactly 1/2 an hour before the fall rains started!

 Invertebrates in the creeks are like canaries in the coal mine for detecting the health of streams. They are food for salmon, trout, sculpin, and crayfish among others and different invertebrates are tolerant or intolerant to different stressors (for example temperature, pollution, desiccation). Knowing what animals are living in our creeks helps us know how to better take care of our watersheds. These surveys are long and involved and we absolutely couldn’t do them on the scale that we do without our community pitching in. Thank you!!!
Data for all past years is stored on: pugetsoundstreambenthos.org
We had many interesting finds this time and the stream teams were super fun to work with at all the creeks.
Here are some highlights:

–In Ellis, despite what looked like a good water level, a cursory look at the samples seemed to indicate very low levels of life. This was puzzling. We will see if this is true as we go through the samples more closely.

Pull! Pull! It’s all fun and games until someone gets their boots sucked off in the knee deep mud…well it’s still all fun and games really. This team was a hoot. photo by: Diane Emerson

–In Gorsuch, we were pleasantly surprised to find a healthy population of small trout. Rusty and Adria were able to catch one. Initially I labeled it a cutthroat as it had the distinctive slash on the throat. However, after turning a photo into the county fish biologist it appears there’s a chance it might be a cutbow which is a hybrid between a cutthroat and a rainbow. This would indicate that at some point this creek may have supported rainbows/steelhead or maybe still does.

It was THIS BIG! Say Adria and Rusty about the cutthroat trout they caught. While it is a little fish it is a super cool find. Last official record of trout in Gorsuch creek was 2001 so it’s great to know they are still around. Also, this might be a cutthroat/steelhead/rainbow trout hybrid as it has characteristics of both. This is significant because while there are stories from old-timers of steelhead in our creeks, there has never been a confirmed record. photo by: Bianca Perla

Small trout in Gorsuch creek. The slight orange chin slash identifies this as cutthroat. However the dorsal parr marks, the white tip of the dorsal that spans more than 3 fin rays, and the solid black outline on the adipose fin all identify this as rainbow/steelhead. Could we have a hybrid “cutbow”? This is a very small fish so it is really hard to tell but it is a possibility.

–In Judd, we found a lot of life! Many caddisflies and stoneflies. This was balanced out with a heavy load of black flies (probably due to the higher temps in the water this year). However, overall the creek looked pretty good. It has consistently improved in quality since King County put logs in this stretch. We also found sculpin, small salmonids (we couldn’t catch them so don’t know whether they were salmon or trout), and a native signal crayfish in a deep pool!
–Plants: we found a small knotweed infestation on Gorsuch (this is highly invasive). In our other stream surveys we found significant patches of morning glory and holly. We will notify the proper management agencies to see if we can get these removed. We might be calling on the community for help if agencies are too booked or under-funded to get it done.
The samples from Ellis and Judd will make their way to the 6th grade science classrooms this fall where Vashon Nature Center scientists will work with students to sort and classify the samples. After this the samples classification is verified by a professional lab and data is uploaded onto the Puget Sound Stream Benthos database (link in text above).  This stream survey work and the classroom unit is supported by Schools Foundation, PIE, King County Groundwater Protection Committee, and the Rose Foundation.
Here is a photo album with more from our time on the creeks. Enjoy!
 
Thanks again to everyone for a great and productive trip to the streams. We could absolutely not do this on the scale that we do without the help of our community. Thank you for helping take care of our streams. 
We do this every year. If you’d like to be involved please email: info@vashonnaturecenter.org

Why? A wildlife management perspective on Vashon’s late cougar

by Bianca Perla  

As I left the wilderness and drove back into cell service my phone exploded with texts. The cougar had been killed. Both kids and adults cried at the news, wondering why. Many in our community disagreed about this cougar but most people seemed to agree on one thing, they did not want this cougar’s stay to end in death and the question of why it did still lingers. Here I draw on my experience as VNC director and as an ecologist to attempt to shed light on why.

We live in a pivotal time of change in large carnivore management. For the past 50 years management has been heavily focused on predator control. Because of this we’ve discovered what happens in areas where predators are absent. Consequently, the books of predator ecology and human-wildlife conflict are being re-written. Yet many management frameworks, societal values and public opinions have yet to reflect this.

In the 1990’s, I helped run howling surveys for wolves in the Frank Church River of No Return Wilderness, a wolf reintroduction effort concurrent with Yellowstone. Through tracking the effect of these reintroduction programs, we’ve learned that top predators can have trickle down effects called “trophic cascades” that promote everything from healthy song bird populations, to diverse forest understories, to less erosive river courses that make better habitat for fish.

We’ve also learned about how traumatic relocation can be. Yellowstone developed a soft release technique that moved family units together and kept them in an enclosure for months before release into the wild. Otherwise wolves scattered from the stress and many eventually died. Wolf reintroduction has also taught us a lot about wildlife conflict and how societal attitudes about predators can sometimes be harder to change than the ecological landscapes themselves.

In the early 2000’s I worked in Yosemite right at the time when bears discovered they could open cars like a human opens a soda can—curl your paws around the top back edge of a door, peel back and pull. Pop! Treats galore. At first, problem bears were relocated. They either found their way back to the valley, or fled the release site to places no one wanted them to go. They also taught their new bear friends and families how to steal food from humans.  Problem bears got three chances and then they were euthanized. Of course, bears did not know or care about this rule of 3.

Then, a light bulb went off in some wildlife biologist’s head. This is not a bear problem, this is a people problem! We need to manage people better. Bear boxes were installed in parking lots.  Fines were instituted for leaving food in cars. Garbage cans were retrofitted with locks. This considerably reduced damage to cars. However, some bears persisted. It was so easy and they had become habituated. So, snipers were installed in parking lots to shoot rubber bullets at offending bears. Through this combined effort of human behavior management and aversion techniques bears learned that car theft was not profitable anymore and the cultural practice of popping open cars has been practically eliminated (reduced by 96% since 1998).

As the above story shows, we are learning that conflicts between wildlife and humans can be solved most effectively most of the time by modifying human behavior. However, for years management focus has been on eradicating or relocating “problem” animals. So, the public is usually still conditioned to expect that wildlife managers do something about the animal even if the problems originate in part from human action.

At this crossroads in wildlife management history, the Vashon cougar swam to us. He crawled out onto the shore of an island that had not experienced living with large predators for at least 3 generations. We were not prepared for the cougar. We were already reeling from having to learn about and adapt to the new coyote population, and even that was not going so great.

During my studies at Stanford University I got a rare opportunity to live on the Zuni Indian Reservation. I worked at the Zuni Conservation Project—one of the first tribally run natural resource agencies. One meeting changed my thinking about wildlife management considerably. It was a meeting between farmers and ZCP biologists. Beavers had arrived and were building dams in the same streams that Zuni farmers used to irrigate their crops. This was causing conflict especially when water levels were drawn down too low forcing beavers to abandon their dams.

The conversation started predictably blaming the damn Game and Fish commission for these damn beavers and their damn dams. I could predict the rest of the conversation: we didn’t want them here in the first place, they are inhibiting our ability to irrigate. What if they grow in population and take over all the streams? Let’s get rid of them.

But instead the conversation proceeded: well just because they weren’t here before doesn’t mean they don’t belong here now. They are raising families in this place. They are telling us it’s home. How much water do they need? How do we keep from pumping the water levels below what they need? The decision was made to raise the level of the irrigation pipes that drew from the river so that they would leave a base level of water. Then farmers would work together to help each other shift to using more drought resistant strains of corn and seasonally phased planting. This happened in one meeting. I was floored.

Back to the Vashon cougar: The officials at WDFW did not want to kill this cougar. They tried everything they could to encourage us to change our behaviors so that both the cougar and our domestic animals could be safe. They spent countless hours on the phone personally talking with residents. At VNC’s request they gave a talk to the community about how to live safely and effectively with large carnivores, participated in radio shows and newspaper interviews. They visited residences suggesting improvements when animals were killed and helped us fact check our Co-existing with Large carnivores fact sheet. They also clearly stated in their most recent interview with Vashon Nature Center’s Kathryn True (an article that ran in the Beachcomber) that euthanizing was the most likely option if this cat was caught.

Sadly, although we were in the process of making changes to adapt to this cougar’s presence, we were not quick enough in the transformation for he and us to reap the benefits. Those who did make changes, thank you. Your efforts are not in vain. Most, if not all, confirmed attacks by the cougar on Vashon were in pastures with high densities of brush, or where animals could access treed areas or were pastured in the woods. We can learn from these experiences. In the future, clearing pastures of brush, fencing animals out of woods areas, or getting animals used to night pens before an attack occurs could help us live more safely with mountain lions.

I don’t know how WDFW’s decision to euthanize was finally made. But from my best understanding based on my experience and talking with WDFW it was a decision based on quantitative information (how many kills/interactions), an analysis of alternatives (relocation liability and precedent), and qualitative experience (will people here change their behaviors to help minimize these conflicts or will these conflicts continue?) The bottom line is we can not pass all the blame to WDFW on this. Our community is also responsible for the cougar’s death.

Here’s a quick run down on why relocation isn’t as neat and tidy as it seems. Relocation is highly traumatizing to a wild animal. Often a relocated animal will bolt at release so it is hard to predict where they will end up. Furthermore, a young male cougar like ours would likely run to the safest place, another urban fringe, to get out of the danger zone of grown male cougars unless he feels brave enough to fight to the death.

Out of curiosity, I looked up how many cougars are killed each year due to problems or conflicts with humans, pets, and livestock. I could find no clear numbers for Washington state (although I learned we have about 2100 cougars). I did find the statistics for Oregon. Oregon Fish and Wildlife, over a ten-year period from 2004-2014 euthanized an average of 180 cougars per year to manage wildlife conflict in Oregon. If you want to pick relocation over euthanizing where do you draw the line? That is a lot of cougars to relocate and there are not enough zoos or wildlife havens in the world to take that many.

Considering this and the fact we still have coyotes, possibly a bear, and at some low tide in the future another mountain lion it makes the most sense to try harder to make changes in our techniques and behaviors. We can be innovative, work together to protect livestock and pets, and put social structures in place that support those who find it hard to do this. We can also lobby our political leaders to allow wildlife managers like WDFW to use our tax dollars to assist landowners in implementing tools for conflict prevention.

Ultimately, a road map for living with wildlife is something the community needs to decide on together. How this will be done in the absence of a community council or any other governing body that can make these decisions is a mystery to me. But, if we work towards adapting to rather than resisting our wildlife we can create a future on Vashon where we don’t have to choose between the safety of our domestic animals and the lives of wild ones. No technique (lethal control, relocation, modifying human behavior) is fool-proof and pet owners and livestock owners cannot be expected to be perfect 100% of the time but we can minimize conflicts considerably. A few changes now will lead to many benefits down the road for our peace of mind, for our conscience, and for our quality of life.

An active livestock management guide, a collaborative effort between VNC scientists, wildlife experts and farmers is currently going through review and due out in September. This will help with wildlife protection practices for coyotes, cougars and bears. Stay tuned.

Barney and Blanche: a tale of barn owls nesting

by: Mark Timken, owl painting by Beatrice Timken

Hope just means another world might be possible, not promised, not guaranteed. Hope calls for action; action is impossible without hope.  —Rebecca Solnet, 2016, p. 4

“Look! An owl!” my partner exclaimed with surprise and excitement, pointing at a large, white bird the size of a seagull gliding away from us into the dusk. It was a cool evening in March 2017 and we were out for a final farm walk of the evening with Gus, the blocky-headed, cream-colored golden retriever. I definitely saw the owl and knew it to be a barn owl, but my internal skeptic reared up and doubted whether the owl had been perched on the deck of our owl nesting box before being surprised by our evening wander.

Like pieces of a puzzle quickly coming together, I started to make connections from some recent odd but significant events. A few nights earlier, on a similar evening stroll, I heard the most intriguing, magical sound I have ever heard. It sounded like Santa Claus and his sleigh being pulled by reindeer—a strange, jingling sound—up by the road. I felt chills erupt on my arms and I guessed that the sound was possibly a courtship song by a male barn owl and, quite possibly, we had just disturbed his partner checking out our owl box as a potential nesting site.

As a kid I always longed to live on a farm on an island. It is one of those unexplained childhood fantasies where, in retrospect, you feel like the future is luring you toward a specific ecological niche, a place the earth wants you to tend and care for. Amazingly, as an adult, and in the most serendipitous way, we found and started an organic vegetable farm and a family, on an island in the Salish Sea.

I must admit to blundering around as a rookie farmer my first year, although I was very aware of the weight of my new stewardship responsibility for the land; this initially included a unique and unexpected relationship with birds. One of the first things I did when we moved to the property was put up a hummingbird feeder. I have been feeding year round ever since and the number of hummingbirds has swelled. I also open up the bay doors to our barn on or around the spring equinox each year to make the space available to barn swallows. Again, their numbers have increased dramatically. It is not exactly Capistrano but exciting nonetheless to have a constant patrol of swallows who were born here and migrated thousands of miles to return here, working above the land, nabbing potentially crop-damaging insects. Some particular species of birds are a farmer’s best friend—the pollinators, aerial feeders, and rodent controllers.

About that time I read and learned about barn owls and how farmers in California were successfully putting up nesting boxes to attract owls to their orchards to control rodent populations without needing to use pesticides. Immediately after reading the article, I ordered two large wooden boxes that high school students were making as a fundraiser and eagerly put them up at a specific height off the ground and facing away from the prevailing wind as directed.

Then I waited. And waited. Nothing. I did some exploring around the island and tried to find the notorious barn owls behind the elementary school and the ones by the private grass-strip airport. There were barn owls on the island but for some reason they weren’t interested in my nesting boxes or this land. It seemed that I had the perfect habitat—open agricultural land and fields, mixed with forest. Years went by. I continued my efforts to improve the health of the land by using compost, planted hundreds of trees and small native shrubs, and pulled invasive plants. Eventually one of the nesting boxes rotted and fell down during a wind storm. The other box was listing badly and I had just recently been considering taking it down because it reminded me of the failed and, what I thought, hopeless project. That was until we saw Barney that night on our walk.

I am curiously aware of our human need or even compulsion, consciously or not, to anthropomorphize animals among other things. I am not proud of this weakness in myself but was simply unable not to name the owls who finally, after 10 years of not-so-patient waiting, took up residence in the nesting box a stone’s throw away from our house. They were virtually neighbors! I convinced myself it would have been rude not to name them! It took me a while and I solicited names from my family until we eventually settled on Barney and Blanche.

After the first Barney sighting, the next night around sunset, I set up my naturalist research camp. All I could think of was Jane Goodall and photos of her African research camp, notebooks, journals, gas lanterns, and her patiently sitting observing chimpanzees. I pulled out an old Crazy Creek chair, got my enormous binoculars, camera, water bottle, cell phone, warm hat, and gloves and encouraged a sleepy Gus to come outside with me; we plunked down maybe 75 feet away from the box out in the open for the best viewing. I felt like I was at a drive-in movie theater
waiting for the show to begin, minus the popcorn, head swiveling wildly in anticipation. I waited. Nothing.

Gus got fussy and eventually dug a huge hole, flinging dirt all over me, excited with his project, but no sign of Barney or Blanche. And then I got tired and the reality of an early morning had me retreating back to the house, dragging all of my stuff. The next night I pulled my camp back further away under an old willow tree that my daughter used to climb called Mother Ruby (I guess the naming thing is an issue).

Eventually, Barney dropped out of the sky like a moth, fluttering in a sing-song way with his familiar jingle, and landed in an old cherry tree next to the nesting box. He had some kind of unidentified rodent lifeless in his beak. I heard a sound from inside the nesting box. It was Blanche begging for food. It was then that I noticed, through the binoculars, Barney was looking right at Gus and me. He knew we were there and the night before we were simply too close for him to start his nightly rounds. He had waited us out. This would become a useful technique for Barney to gain some privacy. It was our first lesson in boundaries with our new neighbors and it would not be the last.

Last fall I volunteered as a Salmonwatcher for the Vashon Nature Center and was in contact with Kelly Keenan, the coordinator of the program. After I felt like I had enough evidence and proof of my discovery with the owls not to embarrass myself, I contacted Kelly for her support and wisdom. My primary concern was the condition of the nesting box. It looked like it was about to fall down at any moment and was in need of further support and maintenance. Kelly encouraged me, much to my concern and anxiety, not to disturb the box or the area now that we
believed Blanche was incubating her eggs.

Kelly generously allowed me to borrow a trail camera with night video capabilities to help understand more of what was happening. Each morning I would visit the camera attached to a ladder in front of the nesting box, retrieve the memory card, and review the videos of the night before on my computer. These 10-second video clips look like X-rays in the dark night sky, but proved to be my window into the world of barn owls and provided incredible details and insight that would have been lost to me prior to this type of technology.

The camera did prove what we initially believed—Barney and Blanche were using the nesting box and Blanche had finished laying eggs and now remained in the box, completely dependent on Barney for her survival. Kelly told me of another nesting box that she was monitoring across the island; she had a theory that potentially fledged barn owls from that box had found my nesting box and knew this type of establishment to be a safe and respectable place
to raise their young. My courting had paid off.

This is where I have to admit that I started to worry and become overly attached to the success of this endeavor and my anxiety about the necessity of its success. There were times at night during winter storms when the wind was blowing so hard, pummeling the house, that I would think of Blanche alone in the rickety box swaying around and I was convinced it was going to fall over, dashing the hope of more barn owls in the world. My mind went to extremes
—dashing the hope of all species. Each morning, much to my disbelief, the nesting box remained standing and the process unfolded just as it was intended.

One afternoon I got a text from Kelly reporting that a male barn owl had been hit by a car and killed. Barney, I immediately thought. It took me two excruciating nights of watching at the camp and video checking to confirm it was not Barney but indeed another unfortunate victim or victims, considering the impact of a single parent in this type of situation. I anxiously thought of raccoons, crows, mink, neighbors who use rat poisons, all the possible ways an owl could die. I had fantasies of rushing out in the middle of the night in the wet and wind trying to rescue owlets from predators, desperately attempting to alter the course of nature. Like the parent of a newborn child, I was exhausted and stressed and eventually I had to come around to the fact that this might not work out the way I wanted it to. There simply were no guarantees.

There is a process of life and death happening and I am witness to it in an intimate way but I have little control over the outcome. I am aware of the external, collective anxiety around climate change and the almost desperate need for “good” things to happen in the face of what is perceived as being all the “bad.” Part of my process included going to a place of imagined hopelessness before I could swing back to find hope again.

Eventually all the collective team-work paid off for Barney and Blanche. Three gigantic, rodent-laden owlets emerged in May with incessant, raucous, and distinct begging calls. The peaceful nights of watching the nesting box from under Mother Ruby changed quickly as Blanche also emerged and proved to be a fierce and intimidating mother determined to protect her offspring from harm. She has a terrifying warning scream that, when emitted, sends me immediately in the opposite direction, instinctively ducking, covering my head with my arms complete with visions of having my skull ripped open, even though she has never actually attacked anyone, not even Gus. My once glorious research camp has now been reduced to a partial view of the nesting box from my closet and, of course, the ever- important nightly video haul.

There is something magical about going from zero barn owls to five flying around the farm that adds a distinct flavor of wildness and giddy chaos. The newly emerged siblings, in their floundering initial attempts to learn how to fly, launched themselves clumsily into nearby trees and practiced landing on the roof of the house, skittering and thumping across the metal above our heads. Neighbors expressed concern and curiosity about “all that noise” coming from our farm; do you know anything about those owls, they inquired. There were barn owls everywhere,
on fence posts, in the trees, on the roof, flopping in and out of the fields. Eventually the plenitude of owls shifted, the siblings fledged, one by one, until only Barney and Blanche remained and, with no pomp or celebration, they started mating again; a second brood is on the way. Can I say that again—a second brood is on the way!

In retrospect, watching owls became a necessity, a strange fascination, and triggered a certain primordial excitement—a genetically programmed longing for connections with the rest of the living world (Clinebell, 1996, p. 41). There is something vitally important for me about sitting outside, with Gus nearby chewing on pieces of random wood, at dusk, most nights, that is grounding and helps alleviate a collective, gnawing anxiety about the helplessness at the edge of the environmental abyss. The longer I sit and observe, the more I can feel my nervous system relax, which is followed by more presence and awareness to what is occurring around me—the sights, sounds, smells.

The genetic longing I feel is to be deeply reconnected to the ecological systems and to help promote a healthy and viable system, a system that produces bountiful, healthy food for humans, elegant swallows, darting, pollinating hummingbirds, and magnificent barn owls, to name a few. If I am paying careful attention, I am aware that something hopeful is unfolding all around me and I am playing a part in making it happen. When Barney and Blanche selected this farm, this land, to raise their family, it in some way confirmed and validated for me that my conservation efforts were paying off, as owls are indicator species—they indicate the health of the land.

Putting up the owl boxes was hope in the form of action. Sure, I could sit here and hope that owls would nest on the farm. By putting up the nesting boxes I made an offering to the mystery, a courting gesture, that said—you are welcome here and I will do my part. I didn’t know what the outcome would be, but I did it just the same. I have been told that owls can hear a human heartbeat from a spectacular distance. Sometimes I wonder if Barney and Blanche can hear my heartbeat accelerate when they show themselves at twilight. Maybe they can sense my intention to help them and my deep curiosity about them. I can’t help but feel grateful that I am in a reciprocal relationship with these owls—an amazing partnership with beauty and wildness.
