    Ponderosa Pines

    • 1744 Words
    • 7 Pages

    Bark beetle outbreaks are often fueled by drought and fire-damaged trees, killing more trees and exacerbating the effects of climate change (CFPC 2015). This paper will be focusing on the decline of one of California’s most abundant species, the Ponderosa pine (Pinus ponderosa). Ponderosa pine trees have a wide range and can be found throughout the western United States, southern Canada, and northern Mexico (Little 1971). Here in California they primarily occupy mountainous regions but have been found in elevations ranging from sea level to 10,000 ft. depending on latitude (Oliver and Ryker 1990). Ponderosa pines are susceptible to further decline as we continue to see increases in temperature and drought in California. It is inevitable that we will continue to see changes in our forest structures so long as we continue to manipulate and influence the natural world. However, what will these changes mean for the health and well-being of humans and wildlife? P. ponderosa is a beautiful tree that provides scenery, solace, and enjoyment to humans and crucial habitat for birds, mammals, insects, and associated understory plant species. Future forest management decisions depend on thorough interdisciplinary solutions to major problems like the bark beetle attacks and…

    And it does in severe ways. For one, climate change is melting glaciers. You may think, what does this have to do with humans besides a little warm temperate? A lot. One of the main reasons being that about 400 million people worldwide depend on mountain glaciers as a water source. Glaciers are crucial for life support in villages such as villages in the Zanskar valley where they get just half an inch of rain a year due to cold temperatures. Not only do the glaciers serve as drinking water but…

    • 7 Pages

    plant, the toadflax is preferentially avoided by the local fauna and this results in this plant out-competing the native species in the region. One of the benefits of intermittent forest fires is to clear the land of such exotic species. This provides the native species the survival edge to repopulate the burnt out forest area and flourish. Natural forest fires also provide the high temperatures required for some plant species to disperse their seeds rapidly. For example, Jack pines (Pinus…

    Out of all, the burned area showed a significant increase in longleaf pines, (Pinus Palustris) and a decrease in woody species, compared to the unburned area. In fact, it jumped from a frequency of 15 in the unburned area to a frequency of 50; which is two times that of the burned area (see figure 1). Compared to all other species of tree, Pinus Palustris experienced the most increase of frequency. Whereas, Pinus Clausa or sand pine, was only present in the burned area showing that it was a…
