Consequently, over the past 20 years, the increase in the regeneration rate of giant sequoias has been noticeable. Other environmental concerns for the park include air quality and drought. Ozone pollution also weakens the trees so that, when natural drought comes along, these damaged trees often die. Partnerships have been formed with foundations, nature conservancies, and even oil companies to provide funding for study and restoration. But the single biggest issue for both parks remains overcrowding -- they are too popular for their own good.
For most of the 20th century and into the 21st, the parks have walked a tenuous line between increasing visitation and consistent management of visitation. Dry summers, especially at the lowest elevations, force plants to adapt to a lack of water and the presence of fire. Mapping reveals the relationship people have with the spaces they inhabit. Complex mapping software, called geographic information systems, allows park scientists to carefully map and analyze Yosemite's , acres.
By understanding where rockfalls occur most often or how fire behaves in these forests, scientists can assess management needs and protect the park and the people within it. Projections of climate change effects, for instance, reveal why wildlife and plants are moving higher in elevation to find suitable habitat. Wilderness: Wilderness is a place unchanged by people: a place of solitude, a place of peace, a place of adventure and learning.
