Salmon, Cedar, Rock and Rain: Washington’s Olympic Peninsula

by Tim McNulty, Coauthor

Immature Bald Eagle at Mouth of Elwha River

In my essay, I explore the peninsula’s natural diversity from its geological origins through alpine, forest, riverine and coastal ecology. I review the peninsula’s epic conservation history, the threats posed by climate impacts, the future of the ecosystem and transformative role of restoration — from the Elwha dam removals through the Skokomish watershed and Hoh River restoration efforts to numerous salmon enhancement projects on the North Peninsula.

Along with my coauthors David Guterson and Lynda Mapes, seven Indigenous writers representing five Tribal nations tell stories of their peoples’ long-standing relationships with the peninsula’s land and waters and explore Tribal sovereignty, language revitalization, self-governance, and the Tribes’ spiritual relationship with this place. More than 30 photographers superbly capture the peninsula’s beauty and diversity.

Notes on Nettles

by Jeanmarie Morelli

Stinging nettles, Urtica dioica, are commonly found in moist sites and can shock the unsuspecting hiker. Often forming large patches under alder trees, they also grow along streams and disturbed sites. This time of year, the young shoots thrust upward from underground rhizomes. Later in the season, nettle plants grow to several feet tall when they produce either male or female inconspicuous flowers. Although nutritious plants, the stinging hairs covering the leaves deter browsing except by insect larvae, including the Painted Lady and West Coast Lady butterflies.

Nettle shoots herald the arrival of spring and an opportunity for wildcrafting. Young plants can be mistaken for mint with pairs of dark green leaves growing in opposite pairs along the square stem. Wear gloves and use clippers. Steamed or boiled nettles can be a spinach substitute. It’s rich in iron. Try preparing a potato-leek soup with a stock of fresh nettle greens and miso. The nettle’s sting is contained in the hollow hairs filled with uric acid. The fresh foliage applied topically has an anti-inflammatory effect on sore joints. (I have found it quite effective on aching elbows.) The fresh plant includes an array of phytochemicals. A report from the NIH confirms: “… Urtica species exert excellent anti-rheumatoid arthritis, anti-gout, anti-inflammatory, immunomodulatory, and antioxidant activities, all of which contribute to the protection of joints.”

Hair Ice

By John Goldwood

Hair ice

Hair Ice forms when specific prerequisites are present: a piece of decaying or rotted wood with specific moisture content; air temperature and humidity in a narrow range; and most importantly, the presence in that rotted wood of a single-celled fungus, Exidiopsis effusa, the critical factor driving creation of these ice crystals.

When conditions are perfect, a tiny droplet of water is forced from a hole in the decayed wood and freezes. A second droplet appears from the same hole, freezes, and pushes the first frozen droplet away from the surface of the wood. This process repeats itself until a single ice strand only 0.01mm in diameter (far smaller than a human hair) may attain a length of several centimeters. The fungi present in the ice crystals prevent the ice strands from clumping together and allow the creation of this beautiful and rarely seen ice formation.

You might walk right past Hair Ice without recognizing it. We frequently have many decaying Red Alder (a preferred host plant for the fungus) branches along our trails. Our humidity and sub-freezing temperatures are often in the perfect range, and our shorter days in winter make it easy to be on the trails shortly before or just after sunrise. If the prior evening has provided little wind, you may find these incredibly delicate and beautiful creations adorning the trail, or perhaps peeking out from the underbrush a short distance away. If you are fortunate enough to discover them, take a moment to appreciate their delicate beauty – but hold your breath!

Salmon Migration

By Chris Jones

We are lucky to live in a place where we can witness the high drama of salmon returning to their natal streams to complete their life cycle. Every river and stream in our region will have some salmon migrating all year, but September through early December is the peak. By early October, the pink (humpy) salmon have nearly completed spawning, and fall chum (dog), coho (silver), and king (chinook) are just entering their home streams. (Salmon seem to have two or more common names.) Steelhead technically are sea-going rainbow trout, and they are in rivers and streams almost year round.

At the locations below, look for chum salmon in the lower reaches of the stream and expect to see coho moving to the upper watershed. Kings and steelhead are sighted less frequently but do occur in larger rivers. Aside from the salmon themselves, look for disturbed, algae-free gravel patches, or “redds,” that mark where the salmon have mated and left fertilized eggs to hatch in the spring. You might see salmon guarding a patch of gravel anticipating a chance to mate.

  • Chimacum Creek: Explore the creek at HJ Carroll Park.
  • Elwha River: Seek overlooks where passing salmon are recolonizing
    after dam removal.
  • Duckabush River: Check the oxbow area protected by the Jefferson Land
    Trust. Use parking area beneath power lines on Duckabush Rd.
  • Dungeness River: Watch from the old railroad bridge at Sequim’s new
    Dungeness River Nature Center.

Intertidal Zonation

By Nan Evans

The tide is out. It’s time to explore. Walk towards the low tide water
level on any shoreline, and there are wondrous things to see. As you
explore, you will notice that the biological communities change from
the high tide level down to the lowest levels. Marine scientists call
this “intertidal zonation.”  Ecologists group the zones into the
Splash, High Intertidal, Middle Intertidal, and Low Intertidal Zones.

Zonation is a complex result of substrate, tidal levels, predator-prey
interactions, and competition for space. Specifics differ between
rocky shores, sandy beaches, mud flats, a pillar under a pier, or
boulders strewn amongst sand and cobbles, but you will always see
changes in plant and animal communities.

At the highest levels, life is hard – too hot in the summer, too cold
in the winter, too dry most of the time, and too much fresh rainwater.
Isolated tidepools can become both too hot and too salty when exposed
to the sun for many hours. In the Salish Sea, the Splash Zone ranges
from about +7 to +9 feet above mean lower low water (which is “0” feet
in a tide table). Here we see only a few hardy species but often huge
numbers of individuals. You will find several lichen species. The
green algae sea lettuce (Ulva) makes its first appearance. A few land
plants that can tolerate the salt exposure may also be present. This
is the zone of barnacles – the small little brown barnacle and the
acorn barnacle. Look closely in cracks and crevices, and you might be
able to spot a few small marine snails and limpets. These hardy
animals feed only when briefly submerged. When the tide is out, they
basically close down tight to keep moisture inside their bodies –
clamping those barnacle plates together, or pulling into a snail shell
to shut the door (operculum), or just contracting those muscles that
allow a limpet to adhere tightly to the rock face. All of these
animals must have the ability to tolerate increasing levels of their
own biological waste products as the hours go by before they are
submerged again and are flushed by sea water.

Lottia digitalis (Ribbed Limpet)

Below this uppermost horizon, we encounter the High Intertidal Zone
that is submerged only during the highest tide levels. Life is
marginally easier in this zone, but its residents are still exposed to
the equivalent of a total of 145 to 70 total days of dryness over a
period of 6 months. The High Intertidal Zone in our area ranges from
about +7 feet to +4 feet above the mean lower low level. We see more
diverse life here. Consult a field guide; the number of species
explodes too much to describe briefly. Lots of algal species: brown,
green, and red. The brown algae Rockweed (Fucus) stands out on the
rocks. In addition to barnacles, there are more species of snails
(including carnivorous and algae-eating species) and limpets. Look
into small tidepools or under a few rocks (please replace them very
carefully!) to find hairy hermit crabs and the dark green and black
tidepool sculpin.

Fucus distichus (Rockweed)

Lower still, we find the ecological communities of the Middle
Intertidal. Communities here are submerged and exposed for more equal
periods of time. This is the area from about +4 feet down to 0 feet
(the mean lower low tidal level). Life really explodes here – crabs,
sea stars, more snail species, goose neck and blue mussels, chitons,
sea stars, and sea anemones. Curiously, the animals of this area are
rarely seen subtidally. They truly are residents of the in-between
world – part terrestrial and part marine.

Cancer productus (Red Rock Crab)

At last we enter the Low Intertidal Zone, which is exposed only during
the lowest tide levels. This is the realm of those marine creatures
who have adapted physiologically and/or behaviorally to survive some
amount of time exposed to air. We see the largest variety of species
in the Salish Sea in the Low Intertidal Zone, 0 to about -3.5 feet.
Some of the species also occur subtidally. Interestingly, although
there are many more different plants and animals, we do not see the
high numbers of individuals of the same species we saw in the upper
levels. Life for a marine creature is easier here, but then
competition for space and food is more intense as well.

Cucumaria miniata (Red Sea Cucumber)

Surfgrass and eelgrass (both flowering plants), plus vast numbers of
species of algae or seaweeds, are found here.  Abundant animal life
includes species of sponges, hydroids, anemones, flatworms, round
worms, segmented worms, sea stars, brittle stars, sea urchins, sea
cucumbers, brachiopods, snails, limpets, bivalve mollusks, chitons,
nudibranchs, shrimp, crabs, octopuses, clingfishes, sculpins,
pricklebacks, and gunnels – to name just a few!

If we use our intertidal visit well, we will explore all the different
zones, probably spending the most time at the lowest levels. But we
must be careful, the tide turns and comes back in quickly, and we may
have only a short time to get back to land before all these
communities return to the sea.
