Timber! Big trees declining in Yosemite

August 3, 2009

Large diameter trees are not doing well in California’s Yosemite National Park — there were 24 percent fewer in a recent decade than the 1930s, the U.S. Geological Survey and University of Washington scientists said in a new report. Climate change is the likely culprit they say, cutting snow pack, which cuts available water, which cuts growth of big trees, which cuts production of seeds for new trees, which — you get the idea, but basically the whole ecosystem is strained.Meanwhile, fewer fires has led to growth in the type of trees that are not fire-resistant — so future fires may be particularly bad, especially with warmer, drier conditions.The comparison of trees in 1988-1999 versus 1932-1936 was published in Forest Ecology and Management.California’s Yosemite may not be alone — Polish woods also face an uncertain future due to climate change, according to a new Reuters story.Photo by ROBERT GALBRAITH/REUTERS

Don’t stop to be greener!Climate change always the black sheep. Yes it is reality, so what? Do not blame any body, we should just take the action. Every movement we take; whether small or big movement, with unconditionally positive intention I believe it will give positive impact.Just think like this: plants on the day time share the pure air (oxygen) with us unconditionally, oxygen is the most essential for our blood to be easier to distribute all over our body, oxygen help most for regeneration cell, and refresh our body.So, this is small tip: always have plant around you; put a pot of plant on your desk and let your plant clean the air. If it gives flower even better! This is what I do, I always bring plant in every room or office where I work in Bali or when I travel.Warm regard from Bali, iyan.

The original Indians of Yosemite were Yosemite-Mono Lake Paiute people and we have a close special tie with the trees of Yosemite. Here are some short stories about that;http://www.indiancountrytoday.com/y ourict/52071242.htmlhttp://www.indiancou ntrytoday.com/yourict/52313777.htmlHopef ully the trees will come back stronger. Chief Tenaya was the founder of the Paiute colony of Ahwahnee

We all think of less Carbon Dioxide emissions these days. But, my question is why all the developed nations including the USA do not have any willingness to sign a Universally Accepted Green Protocol and implement it once in for all. Seemingly the culprits of Global Ecological Debt and Emission Debt do not simply wish to make any compromises at their level yet allowing their back-boned multinational companies to outsource their production lines into developing countries and exploit natural resources as in the past ..

It is just another sign of how our environment is changing for the worse
