In The Nature Episode We Were Introduced To Yosemite National

In the Nature episode we were introduced to Yosemite National park, located in the heart of California’s Sierra Nevada mountains stretching the distance of California. The Sierra Nevada is known for its harsh climates, beautiful landscape, and the incredible Yosemite valley. In this nature episode we saw how global warming is affecting the Sierra Nevada ecosystem due to the devastating drought in California. The episode starts with hang gliders setting their gliders up, and gliding above the valley this is a form of kinetic energy after they have built potential energy up running down the little cliff and gliding releasing energy. When gliding over the valley the glider can see many waterfalls and rivers carved out in the valley. One of†¦show more content†¦To make matters worse California is in the middle of a devastating drought, causing many forest fires. But these trees remain unfazed, as a matter of fact fire is an innate part of this ecosystems, many animals d epend on fires for survival like the black-backed woodpecker who their main source of food are tree inhabiting beetles. When the bark is chard this helps the woodpecker find its food easier. Unlike a lot of other trees sequoias need fire to reproduce. The fire also does 3 things for the sequoias: it heats up and opens the cones releasing seeds, second,the fire makes and opening in the canopy of the trees to allow sunlight to shine through, and finally, the fire gives the sequoias seeds a nutrient rich place to grow (Yosemite, 2017). When winter comes around the ice pack covers the seeds allowing the seeds to be in the right condition to start the process of germination. In the episode they talk to a forest ecologist that works for the U.S geological survey, his job is to monitor the trees response to the drought and in recent years by recording the water content in the clippings they have found that the water content is decreasing. Which is a warning sign that the tree might be dyin g or under stress from the drought. When a sequoia is healthy is clippings are green and have a higher water content, but since the water content is decreasing that the amount of water to keep the cells at anShow MoreRelatedDeveloping Management Skills404131 Words   |  1617 PagesWorksheet 661 APPENDIX I GLOSSARY 673 683 APPENDIX II REFERENCES NAME INDEX 705 709 713 SUBJECT INDEX COMBINED INDEX xvi CONTENTS P R E FA C E What’s New in This Edition?
