The vessels that angiosperms use to transport water may even help their seedlings get off to a faster start than those of conifers. The very harsh winter environments found at high altitudes and high latitudes are a third extreme, and one that has led to a specialized adaptation: deciduous conifers.
The larches, mentioned earlier, are the best known example; a few other genera occur world-wide. Larches rely on needles rather than broad leaves and they grow new needles every year although the needles of juvenile trees may survive the first winter—perhaps protected by the forest canopy above.
How do they do it? First, they grow in areas where there is little competition—other trees are not adapted to the harsh environments in which larches have established themselves. And second, they rely on efficient form and efficient use of nutrients to capture light and grow leaves and structural components.
Come winter, the view from my window will alter. The pines will stand out, cinnamon-orange bark and green needles highlighted by snow. The beauty of the deciduous trees will be starker, the riparian stand more easily penetrated by the eye. Those trees will stand stiller and less colorful. They'll be waiting. Cernusak, Lucas A.

Educational Grants. The berries are typically blue or blue-purple, but can also be red or copper-colored. There are three types of junipers native to the Pacific Northwest, Rocky Mountain juniper, Western juniper and common juniper. Junipers produce a strong odor that is noticeable from a distance.
They are not as long-lived as other conifers, typically living approximately years. KW Schumer is an award-winning newspaper editor, reporter and writer with more than 15 years of experience working for large, mid-sized and community newspaper companies.

How Long Do Conifers Live? By KW Schumer. Related Articles. The Chestnut Oak, for example, lives for years on average and may exist for up to White Ash trees average years but can reach , and the American Beech averages years with a maximum of There are some species of trees that have much longer life spans than most others.
These include the Giant Redwood, which averages 1, years and can reach 2, The Giant Sequoia has an average life span of 2, years and a maximum of 3,, while the Alaska Yellow Cedar has an average span of 1, years but is capable of living for 3, It is rare that a tree will get to live out its full, natural life span.
Just like in humans, diseases can kill a tree, with fungal infections rotting away the wood. Insect infestation can also weaken a tree, causing its death either because it no longer has enough foliage to photosynthesize or it is downed by a storm or winter ice because it's been weakened. A few trees die after being struck by lightening.
