Yosemite National Park By Emily Toth
Biome • At higher elevations, fewer wildlife species tend to be found due to the lower complexity of the forest • Above the tree line, climate becomes harsh with a short growing season • Many rich, diverse habitats: • Chaparral • Coniferous forests • Alpine rock
Climate • Most of its precipitation in January, February, and March • Elevation greatly affects temperature and precipitation • Summers are warm and dry—occasionally, clouds can build up and produce thunderstorm activity • Highs in low 90s • Lows in 50s • In the transition months (spring and fall), sunny days can suddenly turn stormy • Highs from 50s to 70s • Lows in 30s • Rain and snow in early spring/late fall • Snowy/rainy winters; sunny days are possible • Highs from 30s to 50s • Lows in upper 20s
Wildlife ANIMALS • Approximately 40 species are endangered • Consists of more than 400 different species of vertebrates • Mule deer (the park’s only species of deer) • Acorn woodpecker • Sierra Nevada red fox • Black bear • Spotted owl • Bats • Marten • Hermit thrush • White-tailed hare • Rubber boa, alligator lizard, and western fence lizard—reptiles are NOT common PLANTS • Lower elevations: scrub and chaparral • Higher elevations: alpine meadows and subalpine forests • Significant part of the park’s aesthetic appeal and biodiversity • Blue oak • Gray pine • White fir • Giant sequoia trees (the world’s largest living things) • Western juniper • Assorted wildflowers • Mountain hemlock • Monkeyflower
Why Should We Help to Preserve It? • Source of recreation • Mountain climbing • Hiking • Exploring • Swimming • Skiing • Wildlife/Biodiversity • Over 240 species of birds, 80 species of mammals, and 1,400 species of flowers and trees • Cultural heritage • Designated a World Heritage site • Seven different Native American tribes; all people in the tribes work in or around the park
Possible Threats • Loss of natural fire regime • Exotic species • Air pollution • Habitat fragmentation • Climate change • Local problems… • Availability of human food • Occurrence of road kills
Current Conservation Efforts • DNC (Delaware North Company) is doing its best to preserve the park through the GreenPath program—we are doing our best to join their cause • Helped to mitigate 30 sites impacted by deteriorating storage tanks • Created a golf course that’s certified as a Audubon Cooperative Sanctuary • Founded a nationally recognized recycling program
