I will start with the junipers. These conifers have scaly, slightly fleshly leaves. Juniper seeds are embedded in a cone that resembles a green berry. The cones are round and densely fleshy. Junipers are widely adaptable here, from arid foothills to rocky alpine slopes.
Our pines collectively span this same elevation range. They are the only conifers that have cylindrical needles bundled in clusters of 2 to 5. The one exception to this is Single Leaf Pinon, which as you might guess has single, round needles. The count of pine needles is often diagnostic of their species. Pinons mix with junipers at low elevations; their oily, wingless seeds are the edible pinon nut. Bristlecone pines, found in southern Utah, can live for over 1000 years.
Spruces are conifers that many recognize from their own yards. The spruce needle leaves a peg on the stem when it drops, which gives their twigs a rough, nubbly surface. Spruces grow in a classic pyramidal shape. Another montane group is the true firs. Their flat needle attaches smoothly to the twig. True firs have uniquely upright cones that gradually disintegrate without dropping to the ground. Crushed fir needles are wonderfully fragrant, redolent of tangerines or grapefruit. Perhaps that is why true firs are a favorite Christmas tree.
Conifer trees are a great resource for Utah wildlife, providing food and shelter, especially in the icy cold of winter.
