Posts Tagged ‘South East Alaska’

After lunch on 24th June, the “Sea Lion” relocated further north up Chatham Straight to Sitkoh Bay which is a narrow inlet on the southern end of Chichagof Island and directly across the Straight from Angoon.

The story of this bay provides an insight into the consequences of the way resources are harvested and why it’s so important to understand and respect relationships in the environment. This is a story that wasn’t told to us on board the ship, but it probably should have, could have, been. It’s a story I’ve had to piece together from my own research.

This 8 km (5 mile) long bay is fed by the Sitkoh River which, in turn, is fed by a mountain lake. And that’s just the type of environment Sockeye salmon require in order to spawn. But this type of stream is comparatively rare in South East Alaska and, when man changes and spoils this pristine environment, so the numbers of Sockeye decrease markedly.

Summer Camps on Sitkoh Bay

Summer Camps on Sitkoh Bay *

The first humans known to come to this bay were groups of native Tlingits who made their summer camps along the edges of the bay. Tlingits had lived in South East Alaska for 10,000 years before the first white men arrived. They were subsistence harvesters of fish and they understood the importance of not over fishing and also the need to keep the environment clean for the fish to spawn. They fished according to their need.

Each year, the Tlingits harvested some of the Sockeye as they moved upstream. At that time, the fish were full of fat; good food but difficult to smoke for later consumption. These were eaten immediately. Fish caught after spawning, the ones that would die naturally anyway, were less fatty and able to be smoked for later use in winter. There was a healthy balance between man and resource.

Sitkoh Bay in Relation to Sitka *

The first pressure placed on the numbers of Sockeye in the bay came after the Russians took the land around Sitka by force in 1804. Many Tlingits fled over the hills from Sitka to live in the Chatham Straight area. More people put pressure on the bay in summer and fights broke out between the different groups. But there were still sufficient Sockeye salmon for all.

This balance in nature changed dramatically in the years after the Chatham fish processing plant was built in 1900. It was set up to take advantage of the rich resources of Sockeye in this bay.  When the Tlingits expressed their views on the way the fish were being over-harvested, they were silenced by armed US guards. The price for good red Sockeye was high in the market and the Cannery made of the most of Sitkoh’s summer spawning runs.

While some Tlingits were employed by the cannery, at a very low rate of pay, the owners of the cannery continually refused to listen to them about the need to take fewer fish. As a result, by 1920, the numbers of Sockeye had begun to diminish markedly.  Eventually, the cannery closed in 1974 but not until the Sockeye had been almost totally fished out. 

The third pressure that beset the Sockeye salmon was forest logging around the mountain lake that fed their spawning stream. Logging took place in this pristine valley between 1969 and 1974 and, according to research reports, silt had a big effect on muddying the stream and on changing the water temperature. Since logging ceased, efforts have been made to clean up the water ways and the Sockeye are recovering in number. Fortunately, nowadays more is known about the interdependence of life in the wilderness and changes are being made.

There’s not much left of the Chatham Cannery site and its village. When in use by the Cannery, the inhabitants were segregated into three areas; White owners, Asians and Tlingits. It’s still used by Tlingit peoples for summer harvest of salmon.

Much of the once bustling village is now derelict!

No-one uses this jetty anymore. It stands as a mute reminder of the days of the cannery and the consequences of not understanding the needs of a natural resource.

Up until this point on our walk with David in the forest at Ideal Cove, we’ve been looking down at small plants, mosses and fungi under the trees; but if we look up, we’ll see that many lichens and mosses have taken up residence on the branches.

And while we’re looking up and out instead of down, it’s worth being very aware of the prickly plants in this forest. They don’t know not to grow over board walks!

P1100429

Streptopus amplexifolius © DY of jtdytravels; P1100429

Back down in the understory of the forest, David found this Streptopus amplexifolius, an unusual plant, commonly called Clasping Twisted Stalk. The base of each leaf surrounds or clasps the stem which kinks and twists after each leaf. The buds and bell shaped flowers hang down below the leaves at each leaf axil. They can only be seen by lifting the large leaves.

Another common name for this plant is Watermelon Berry, which refers to the water-melon coloured berries. Although the berries are very juicy, they are not very flavourful.

P1100431

Coptis asplenifolia © DY of jtdytravels; P1100431

Another interesting plant which grows on the forest floor is Coptis asplenifolia, commonly known as Fern-leaved Goldthread. Its a delicate, evergreen herb, with fern like leaves.  It grows from gold coloured roots; hence the common name. The photo shows the unusual seed head; a ring of up to twelve seed filled capsules on an upright stalk. Each time a capsule is hit by  a raindrop, a seed is ejected. Because these plants are slow colonizers, when found in a place like this, they signify that this is an old growth forest.

This delicate pink aster was a surprise find in the depths of this forest.

It’s not a garden escapee! There’s not a garden for many miles. It belongs here.

P1100434

Fauria crista-galli © DY of jtdytravels; P1100434

Fauria crista-galli is commonly called Deer Cabbage. The flowers certainly look attractive but they have a very bad aroma; a pretty sure sign that they are pollinated by flies!

P1100438

Platenthera unalescensis © DY of jtdytravels; P1100438

Platanthera unalescensis, is one of the Alaskan Rein Orchids. You need to be fairly observant to find this delicate plant with greenish flowers. It grows in dry to moist coniferous forests, so is happy in the area that we’ve been exploring with David.

P1100440

The boardwalk crossed boggy, undrained land, known in Alaska as muskeg. It’s characterised by sphagnum moss vegetation and David found the very small  plant called Linnaea borealis growing in the mosses. Since the plant itself is less than 10cm tall and the drooping flowers are only 2-5 mm long, this was another case of needing to get down to ground level. By doing that, David was able to actually look into the flowers and show us that the bell is darker inside than out. It’s a shame that he couldn’t bring us back the smell of these flowers, too, as they produce a very fragrant perfume. All in all, a truly lovely plant.

P1100437

Linnaea borealis © DY of jtdytravels; P1100437

The plant is so lovely that it was said to be the favourite plant of Linnaeas, the Swedish botanist who became famous for introducing to science the system of using binomial Latin names. And so the generic name for the plant is Linnaea, in his honour.  The plant’s specific name is borealis, meaning northern. In Alaska the plant is found only north of Ketchikan.

P1100436

Twin Flower is the common name of Linnaea borealis and that’s very apt. Each upright flower stalk divides into a Y; and each branch of the Y bears a single, delicate, bell shaped flower. The stems themselves are rather hairy, slender, semi-woody. The plant is evergreen and spreads across an area from runners. Seed is also dispersed when the fruit, or dry nutlets, which have sticky hairs, catch onto the fur of animals and the feathers of birds.

P1100444

Lysichiton americanum © DY of jtdytravels; P1100444

Another plant very common in the wet, boggy muskeg is Lysichiton americanum. It’s common name of this plant with huge, rubbery leaves is Skunk Cabbage. The tiny flowers of this plant are arranged on a fleshy spike called a spathe. Deer enjoy eating these spathes and brown bears dig up the roots to eat. They don’t seem to be put off by the ‘skunky odour’!

P1100447

Carex lyngbyaei © DY of jtdytravels; P1100447a

Another very common plant is Carex lyngbyaei, Lyngby’s Sedge. They are grass-like but they are not grasses. The leaf base of a sedge forms a triangle in cross section while the the leaf base of a grass is round. The whole of this plant is rich in protein and is a very important source of food for bears, especially in spring before the berries fruit and the salmon run

Still no sighting of a bear today, though.

P1100448

Moneses uniflora © DY of jtdytravels; P1100448

Moneses uniflora is a member of the Wintergreen family and is also known by the name of Pyrola uniflora. It’s common name is Shy Maiden, coming from the greek derivation of its name monos, meaning one and hesia, meaning delight. And delightful it is. However, it’s a difficult flower to photograph as it grows low to the ground (only 3 – 17 cm tall) in the shade of the deep forest. This was yet another time that David needed to get down to ground level.

Another common name for this plant is Wax Flower because of the single white, waxy flower that grows from a rosette of roundish leaves. However, the common name that I most like for this demure flower is Shy Maiden, for obvious reasons!

P1100441

Menziesia ferruginea © DY of jtdytravels; P1100441

A much larger plant, a scraggy shrub, is Menziesia ferruginea often called Rusty Menziesia, from the species name, ferruginea which refers to the rusty salmon colour of the flowers.  But this common forest shrub is also known as Fool’s Huckleberry or False Azalea. It seems to be masquerading as something other than itself!  The urn shaped flowers are somewhat similar to the huckleberry flower in both colour and form, hanging down. But when this plant is in fruit, the flower stems turn up and the fruits are not delicious berries, but very dry inedible capsules.

P1100442

Rubus spectabilis © Dy of jtdytravels; P1100442

One plant that certainly did have edible fruit was the Salmonberry, Rubus spectabilis. Found close to the edge of the forest, they made a tasty bight for weary walkers on the way back to the shore line. They certainly look inviting and taste something like raspberries.

P1100397

Some forest plants are easy to overlook simply because they are common… like ferns. These plants form an important part of the understory especially at the edge of the forest. They maybe common… but are really rather lovely.

P1100451

Fungi © DY of jtdytravels; P1100451

Something else on the forest floor that many people walk past without so much as a glance is fungi. But how stunningly simple and beautiful are these; another down on the ground photo!

I’m sure there were more plants to find and photograph, but, as always happen in a group situation, someone calls ‘time’; time to go back to the ship.

P1100462

Fucus distichus © DY of jtdytravels; P1100462

But even as David left the depths of the forest and stepped back on the rocky shore, he found yet one more plant to share with us all, the Rock Weed, Fucus distichus. This brown alga grows in clumps or tufts from a basal ‘holdfast’ that anchors it to the rock. It lives in intertidal zones. When covered with water, this plant is erect, very stiff and cartilaginous. However, as shown here, when out of the water the fronds don’t stay erect but fall against the rocks.

Sitting amongst the Rock Weed, and also waiting to go back to the ship, and lunch, was our expedition’s professional videographer, Ross Weinberg. His task wast to prepare a video diary of the trip for everyone…. and he did an excellent job including places, people and some of the fun that we shared.  David often uses video but, on this trip, he chose photography to enable us all to share his plant hunting expeditions by means of this diary.
