This particular organism has adapted itself so that is able to grow in cold weather climates, not requiring large amounts of water to survive, while also being able to grow in adverse soil conditions.  It is resistant to drought, transplantation, and pollution.  It does require full sunlight to grow successfully, and prefers an environment where it is somewhat moist and acidic, but will adapt to almost any rough soil conditions.  It has adapted to not requiring large amounts of water by having need-like leaves that have a reduced surface area for water loss, and a thick waxy cuticle that encases the needles, also reducing water loss.  The reason it is able to adapt so easily to less than ideal soil conditions is because of its root system.  It is very dense and does not need to be very deep beneath the soil remaining near the trunk of the tree.
