Dear Aggie: How climate affects tree size | Home and Garden

Dear Aggie,

I’m from the West Coastline and I appreciate the huge trees that improve there. Why are there no huge trees in Northern New York, or on the East Coast?

A: It is largely a subject of species and weather. The huge, native West Coast conifers these kinds of as redwood, sequoia, Douglas fir, Sitka spruce and ponderosa pine, will grow in the east, but they will under no circumstances get to the heights seen in the west. This is because of to extremely specific local weather problems that exist on the West Coastline. In specific locations coastal fog combined with considerable winter rain, together with reasonable temperatures, allow the trees to improve 2 to 3 feet for each 12 months.

The Pacific temperate rain forest, which extends from Prince William Audio in Alaska down to northern California, is property to the largest trees in the globe. Sitka spruce, Douglas fir and ponderosa pine normally increase to heights properly more than 100 feet. And of class, the redwoods and sequoias are the champions with ordinary heights outside of 200 feet. A coastline redwood with a peak of 379 ft is the tallest tree in the world.

Our temperature disorders just will not help this tremendous style of development. Plus, we get regular ice storms that knock back tree crowns cutting down their height. In addition, our indigenous species just do not have the genetic capability to improve into giants.

At one particular time the East Coastline did have really substantial trees. The japanese white pine is the tallest tree in japanese North The usa. Just before colonization white pines with heights more than 250 ft had been popular. But the original jap forest was distinct-lower by the mid-19th century to fuel an increasing nation. Other huge species that remained, like American elm and chestnut, succumbed to disorder by the mid-1900s. What we see now is a 2nd progress forest that is significantly less than 200 many years outdated — not lengthy ample for the trees to improve further than 100 ft in top.

There are some pockets of what is referred to as “old growth” forest in the Northeast (much less than 1% of the pre-colonial forest stays). To be labeled as old growth the trees must be about 200 a long time aged and the forest ought to be untouched by human action. Northern New York does not have substantial outdated progress forests, but there are a number of places that are house to outdated advancement trees such as the Pine Grove Boat Launch and Selkirk Shores Point out Park, each in Oswego County. In Jefferson County old development trees can be observed in Thousand Island Park, Lakeside Cemetery in Sackets Harbor, and 4-H Camp Wabasso in Redwood. These trees aren’t giants, but they are pretty outdated.

Cornell Cooperative Extension is cataloging aged and significant trees in Jefferson County. If you know of a tree that is remarkable in top, trunk diameter, or crown distribute, be sure to call Sue Gwise at [email protected] Another person from the extension will stop by the tree, choose measurements and images.
