How can you tell different types of conifers apart?

Why do you need a twig for needle identification?
Because the base of the needles or needle bundle in some species is covered in a very thin sheath, you should use a twig for identification, not just a single needle. You will therefore be able to properly observe how the needles or needle bundles are arranged.
Why are seed cones considered fruit?
Once fertilized by the pollen, the ovules become seeds. As of that time, the seed cone is considered a fruit because it has everything needed to reproduce a tree. Seed cones are useful means of identification because they persist on the tree or on the ground around it. Seed cones are often called simply cones.

What trees shed their needles?
When do evergreen conifers shed their needles? 1 Northern white-cedar ( Thuja) shed branchlets in fall that have completed their life cycle; you may see these hanging in the tree. 2 Spruce ( Picea) and fir ( Abies) species thin their older needles progressively, so they may appear fuller and greener throughout the year, even during fall needle drop. 3 Yews ( Taxus) drop their old needles in the spring or summer, which can look especially alarming during the period when most shrubs and trees are producing new green growth. 4 White pines ( Pinus strobis) drop the most needles at one time (in early fall) and can drop needles that are as young as two years. Because the number of older needles on the tree far exceeds the current season’s new needles, white pines can look as though they’re unhealthy or stressed. While it may seem like more of the foliage is dropping than is staying on, it’s a natural process that the tree is prepared for.
