Saco, Me., to Westport, Mass.

We stayed up late last night singing around the camp fire. Glenn mostly led the singing, with help from Amy, and drumming by Richard. Jon and I helped out where we could with uke and guitar. At Jean-Pierre’s urging, Milene sang us a traditional French Canadian song. Chantelle and some others went to bed at ten, but we kept going until quiet hour. It was after eleven when we got to sleep.

We had a leisurely morning. We packed up our campsite and loaded up the car. I enjoy packing up campsites and loading cars, so this proved to be a pleasurable morning for me. Then we ate an early lunch at a picnic table. Richard happened to be there, and we had a long talk, covering everything from Gilles Deleuze and the relationship between colonialism and religion on the one hand, to updating each other on the details of our personal lives on the other hand.

After lunch, I went out into the woods behind Ferry Beach Park Association, while Carol-the-extrovert went off to talk with people. I took a number of photographs of plants and other organisms which I uploaded to iNaturalist. I was sad to see that nearly all the Eastern Hemlocks (Tsuga heterophylla) were infested with Hemlock Woolly Aldegids (Adelges tsugae), an invasive insect from Asia. Many hemlocks were badly infested, and I also saw several dead hemlocks. I have also noticed that there were almost no Black-throated Green Warblers nesting in the woods this year, in contrast to past years when they were numerous. I wonder if the Black-throated Green Warbler prefers hemlocks for nesting, so that the loss of the hemlocks may mean the loss of the warblers.

On a more pleasant note, I came across a Glossy Ibis in the pond just to the north of Ferry Beach Park Association. I’ve never seen a Glossy Ibis there.

We began driving south at a quarter to four. I asked Carol if she’d mind driving because I didn’t think I was alert enough to drive. It was a good thing she drove, because I slept for most of the three hour drive.

We arrived at our summer rental at a quarter to seven. We got dinner at Lee’s Market in Westport. We met one of our neighbors, a skunk who appears to be living under the house. We feel quite settled in, and now we’re ready for bed.

Saco, Me., to Bath, Me.

This afternoon, Carol and I drove up to Bath, Maine, to sing Sacred Harp on the gazebo in the center of Bath. It turned out to be an excellent place to sing, which may show that a good singing space does not need walls if you have a wood ceiling and a wood floor. And with no walls, we were much less worried about transmitting COVID, especially with the stiff breeze that was blowing. It also turned out to be an excellent group of people to sing with. As Carol said after the singing, “It was a really tight group.”

After the Sacred Harp singing was over, we got takeout food. We ate dinner in a city park overlooking the Kennebec River. This is the furthest east we will travel on our cross-country trip.

A quick meomry from our cross-country trip that I forgot to write down earlier:

When we drove into Wyoming, a sign directed all vehicles with watercraft to pull into the Port of Entry for inspection — “including canoes and kayaks.” Signs directed us around the weigh station to a small building belonging to the Wyoming Fish and Game Department. A polite young woman carrying a clipboard and wearing a Fish and Game uniform greeted us. She was obviously checking for invasive species. She looked at the canoe on top of our car, and at our California license plates. “What was the last body of water you had the canoe it?” she asked.

I thought for a moment. We hadn’t used the canoe in the whole 13 years we’d lived in California. “The Atlantic Ocean,” I said.

She looked surprised. “Whereabouts?” she asked.

“Coast of Maine,” I said. “Saco Bay.”

She knew Saco Bay, and it turned out that she, like me, was from Massachusetts.

“Where’d you grow up?” I asked.

“Near Essex,” she said, and told me which town.

There was no one behind me waiting to have their boat checked, so we chatted for a bit. We asked what brought her out to Wyoming. She had gotten her degree in wildlife management at a university in New York state, worked for a while in the northeast, then decided she wanted to go some place completely different. So she chose Wyoming.

I told her I was glad that Wyoming was checking all watercraft for invasive species. “I’m a fisherman, and invasives have already ruined too many fisheries,” I said.

Especially the mussels,” she replied.

So yeah. If you own a boat, remember: clean, dry, and drain.

Acton, Mass., to Saco, Me.

Abby and Jim’s back yard proved to be a very comfortable place to sleep. As we were packing up the car to leave, I noticed these charismatic European Paper Wasps (Polistes dominula) building a nest.

Native to Mediterranean Europe, P. dominula was first introduced to the United States in Massachusetts in the 1970s. Since then, it has spread to Maine, Pennsylvania, Michigan, South Dakota, Nebraska, Arkansas, Washington state, and perhaps elsewhere. Abby said she was going to kill the insects and remove the nest, which I am glad of — according to the Invasive Species Compendium website, P. dominula has been shown to displace native Polistes species.

Another dreary drive today, though only two hours long. Traffic was heavy and aggressive from Acton to southern Maine. We were glad to get off the highway, and set up our tent at Ferry Beach Conference Center, where I’ll be leading a workshop in ecological spirituality for the next week. I’ll post more about that workshop in the coming days.

Sawyer Creek, Oshkosh, Wis.

Dad-in-law and Nancy live near Sawyer Creek near where it drains into the Fox River. So that’s a natural destination when we go out for walks. I went out walking around Sawyer Creek this morning, starting along the north side near Eagle Street, crossing the creek at North Westfield, then following along the south bank through Red Arrow Park. Quite a few plants were in bloom, including attractive but invasive flowers Foxglove Beardtongue (Penstemon digitalis) and Creeping Bellflower (Campanula rapunculoides). Purple Crownvetch (Securigera varia), another invasive species, were everywhere, with their feathery leaves and clover-like pink-and-white blossoms. I was interested to see flowers of the invasive species Flowering Rush (Butomus umbellatus), a plant I’d never seen in bloom before. Actually, most of the flowers I saw were invasive species.

I did see one or two native species blooming. There were some elderberry (Sambucus sp.) in bloom, which were probably native. And some of the small scrubby willows (Salix sp., prob. Salix interior, or Sandbar Willow) growing along the south bank of the creek still had some catkins in bloom.

In the early evening, I went fishing along this stretch of Sawyer Creek. I couldn’t see any evidence that the water was flowing. The turbidity was high, and in some places the acquatic plants were pretty thick. I found a place with few plants, and at my first cast a small Yellow Perch (Perca flavescens), a native species, chased the lure right up to the bank. It was so small that it couldn’t actually get its mouth around the lure. I could see I wasn’t going to catch anything, and that was fine with me. I spent a happy half hour trying to read the stream, casting, and changing lures every once in a while. For me, fishing is better than mindfulness meditation: it clears my mind, and I have no concerns about whether I’m engaging in Whitened Buddhism.

My iNaturalist observations for June 29.

Not only climate change

The BBC reports that toxic chemicals in the environment are just as big a threat as climate change:

“Chemical pollution has officially crossed “a planetary boundary”, threatening the Earth’s systems just as climate change and habitat loss are known to do. A recent study by scientists from Sweden, the UK, Canada, Denmark and Switzerland highlights the urgent need to turn off the tap at source. Many toxic chemicals, known as persistent organic pollutants, or POPs, don’t easily degrade. They can linger in the environment and inside us – mostly in our blood and fatty tissues – for many years.”

A couple of years ago, I heard a talk by Dr. Stuart Weiss, a field biologist in the San Francisco Bay Area. He identified five major threats to the life-supporting systems of planet Earth:

1. Global climate change
2. Land use change (including deforestation and habitat destruction)
3. Invasive organisms
4. Toxication (including solids, like plastics, as well as chemicals)
5. Overpopulation

I would add one more — nuclear war — for a total of six major threats to earth’s life-supporting systems.

Upper middle class Americans have focused on climate change as the major environmental threat. But even if we solve the climate change problem, any combination of the other five threats would also lead to a “great extinction.” This is why having everyone buy an electric car is not going to fix looming environmental disaster. My guess is that major systemic change is needed, probably involving replacing capitalism with an economic system that is not a-moral (or immoral).

The biggest environmental threat in California?

Here’s another environmental threat to keep you up at night:

“Nitrogen deposition and pollution is [a] more acute threat than climate change. … [But] few people are paying attention.” — Dr. Stuart Weiss, Chief Scientist of Creekside Science.

Weiss’s key paper on Bay Area nitrogen deposition, written while he was at Stanford, has a great title: Cars, Cows, and Checkerspot Butterflies: Nitrogen Deposition and Management of Nutrient-Poor Grasslands for a Threatened Species (Conservation Biology, v. 13 no. 6, Dec. 1999, pp. 1476–1486).

I’m listening to Weiss talk to the California Naturalist class I’m taking right now. Weiss makes some interesting points: Smog does an amazing amount of damage, not only to human lungs but also to non-human organisms. Non-native grasses are big contributors to the increase in pollen in recent times. Free-range cattle on California grasslands can keep non-native invasive grass species under control, providing habitat for endangered species as well as reducing allergens.
