The fascinating Sitka spruce
I recently heard a joke and this is how it goes: “What do you do if you are lost in the Icelandic forests?” You just stand up!
Downy birch (Betula pubescens) was the backbone of Iceland’s native forests. It covered 20% of Iceland prior to Norse settlement in 9th century. Over harvesting and free range sheep grazing has left Iceland devoid of its native forests. While Iceland appears beautiful to a visitor and is on bucket list of every hiker, Iceland’s soil erosion is described as catastrophic. The seedlings that come up against the soil quality odds have a further hard time surviving sheep grazing. Those that do survive struggle to grow into trees with a vertical form and grow as shrubs instead. In places where reforestation is afoot, Sitka spruce (Picea sitchensis) are coming to rescue. The Sitka spruce can withstand far adverse conditions than the native birch, including standing up to coastal salt and high wind. So, they are being planted first and when they mature, the more delicate species are grown in the nooks protected by Sitka spruce. To learn more about Iceland’s reforestation challenges, go on to watch “How do you grow trees in a treeless land?” (link)

For me, Sitka spruce is a memory switch. It reminds me of a trip to Alaska where I had fly-fished for salmon standing in waist deep glacial waters while watching a bear mom catch salmon for her two toddlers.
Soon after I had seen the Sitka spruce first hand, Gordon Hempton had referred to Sitka Spruce as nature’s largest violin. Gordon describes the recording event on his website: “I’ve positioned my microphone system that replicates 3-D human hearing inside a giant Sitka spruce log. This tree grew in the nearby rain forest and then floated down the Bogachiel River before coming to a rest (temporarily) at Rialto Beach. The wood of this tree species has special properties that make it ideal for crafting violins, guitars, and other acoustic instruments because the wood produces a sound when exposed to the slightest vibration. But here, instead of a bow drawn across violin strings, the sound of distant surf is powerful enough to cause this Sitka log to produce its own deep, harmonic concert.”
He had shared with some of us the sound this violin produces. I am musically challenged, to me it had sounded more like united heartbeats of creatures that had congregated by the ocean, hearts fluttering in mild anxiety, in heightened anticipation…
A slug rises

A headline caught my eye a few weeks ago – Assembly Bill(AB 1850) passed recognizing the banana slug as the official state slug. It took a bill – not scientists! A slug joined other well known symbols, like the California grizzly bear and the California poppy. That is when I looked up the list of California State symbols and learned about the lesser known symbols such as the California quail (1932) and Golden trout (1947). Call me silly, but I was expecting to find weed on the list. Anyways, I adore this slug, it is yellow, it is large, and it lives on our forest floors. They are caretakers of the giant Redwoods, our state tree. They eat plants that compete with the Redwood seedlings but never the Redwood seedlings. Somehow they know that these little Redwood seedlings one day will become the giants that will give them back the moist forest floor.
