Current Human Impacts
• Tourism accounts for much of the human impact
– Bringing non-local firewood into
Devil’s Postpile can introduce invasive species that then compete with native species (NPS,
n.d., g)
(Pavangkanan, 2008)
• Current air pollution from California
Central Valley and San Francisco is
“potentially phytotoxic to local flora, including highly sensitive species such as ponderosa or Jeffrey pines” (Bytnerowicz, 2013)
(Lea, 2006)

Future Human Impacts
• If current trends continue, climate change could cause loss of biodiversity to this sensitive ecosystem
• Air pollution effects could worsen, resulting in loss of sensitive species
• Increased tourism could cause habitat destruction and further introduction of invasive species

Guidelines
• Implement a robust monitoring program for especially diverse biotic factors, including birds, bats, and plants (NPS, n.d., h)
• Set quota for number of annual visitors and do not allow visitors to bring outside species in
• Continue to monitor abiotic factors including mean temperature, ozone and nitrogen oxides, and Please note that this is task example. No portion of this example should be used in snowpack your submission for this assessment. This example cannot be cited as a source.
