Siberian Larch
Larix sibirica Ledeb.

Field Notes
Description:
The Siberian Larch is a deciduous conifer that abscices its needles in the fall. Its colour ranges from light green in the spring to dark green in the summer and its most spectacular colour, golden yellow is witnessed during fall just prior to leaf drop. It is in the Pinaceae family, until the fall the Larch closely resembles a Pine. It is a tall slender tree but more full in comparison to other conifers in the area. This tree is approximately 28.56 meters tall.
Habitat:
A Siberian Larch is dominant in Boreal forests in Siberia, which is why it can tolerate the harsher climate of AB. It is of European ancestry. The tree is located near the Land Science building in bed # 2 called the "Pinetum". The Pinetum appears to be a mini Boreal forest created on the Olds Campus. It is part of the Taxonomic collections that showcase not only species but the classification and also show evolution. The soil is high in acidity and has a sandy peaty feel under multiple layers of mulch and absciced needles from the Larch and its neigbouring Pines.
Notes:
Some of the lower branches of the Larch have died back. On further investigation I was able to find live mite on several of the cones. Given the time of year the infestation of mite will likely be eliminated by the extreme cold temperatures expected during the winter. Though that is not a guarantee If it was a smaller plant I would apply an insecticidal soap as a first measure although pruning back the dead branches will definitely help with pests. A spring check up is presecribed by an arborist :)
Excellent for shelterbelts, drought tolerant
