Description

The North Side
*****
This painting is currently available, and priced as framed in a simple gold frame, with white mat and colorful liner. Please contact the artist for photos of the art, as framed.
*****
The North Side depicts, in a quite abstract form, a stand of aspen trees covered in deep goldish green moss or lichen, such as is often seen on the northern slope. Leaves are blowing in an autumnal breeze, clouds moving through the sky, and a glint of gold sparkling throughout.

Why does lichen grow on aspen trunks?
According to: http://files.webb.uu.se/uploader/858/BIOKand-13-028-Petersson-Linda-Sammanfattning.pdf
What makes aspen such an important host for lichens?
Aspen, Populus tremula, has a unique lichen flora and many of the lichens found on aspen
are so called host specific, meaning that they only live on aspen. There are several factors
that make aspen a unique habitat for lichens. The bark is probably the most important one. It
has a higher pH value than other common trees, it is very thick which give the lichens a
better grip and a bigger surface to grow on and it has a big water holding capacity. This
plays a major role for lichens, which are very sensitive to dehydration. There is also a high
level of nutrients available on the bark compared to other trees. All of these factors create a
unique microenvironment on the trunk of aspen trees. It is not only the chemistry of the bark
that affects the lichen community, the bark structure affects it as well. Generally lichens
prefer a rough bark since it gives a better grip and more surfaces to grow on. Old aspen trees
are more important for lichens because they have this rough bark that young trees simply
have not had time to develop yet. The structure and density of the canopy can also have an
impact on the trunks microenvironment. Among other things it affects the amount of light
that reaches the trunk.
Conservation of aspen and its lichen flora
The best way to preserve lichens
dependent on aspen is to preserve
aspen itself. Because of efficient
combating of deciduous trees during
the middle of the 20th century there is
a lack of middle-aged aspen in todays
forests. This will lead to a lack of old
aspen in large parts of Sweden in 30
years time. Many lichen species are
dependent specifically on old aspens
and therefore this will most likely
have a negative effect on them. To
preserve lichens, it is important to
have both young and old aspen stands
in the same forest. Lichen species can
then disperse from the old stands to
the young when these develop the old tree qualities the lichens need. Therefore it is equally
important to preserve old aspen trees as ensuring the continued reproduction of aspen. A way to make sure old aspens do not disappear from the forest is to save aspen trees when
making clear-cuts. However, the microclimate on the trunk is changed when the tree is no
longer surrounded by forest and because of this, not all lichens can survive in the clear-cuts.
One way to benefit more lichen species is to leave groups of trees instead of single ones, but
still there will be species that cannot survive in the changed microenvironment. Therefore it
is important to conserve aspen stands inside the forest as well. Aspen reproduction is
dependent on regular disturbances, especially forest fires. Conservation burnings, that is
planned and controlled forest fires, is a way to benefit the aspen reproduction. Also a
reduced elk population, by increased hunting or an increased population of natural predators,
such as wolves, would reduce grazing on young aspen trees and allow more of them to reach
maturity.
