Why is Larch called Juniper in Nova Sotia?

There are lots of anecdotal examples around, but how/why is Larch (Tamarack) sometimes referred to as a Juniper? Larch is deciduous, Juniper is coniferous. Although in some areas Juniper can grow into a large tree, it is mostly a shrub, especially in eastern Canada, Tamarack Larch is used in shipbuilding, and construction where water resistance is important. I have also seen a fine example of Tamarack flooring!
