The
excessive levels of nitrogen coming from nitrogen compounds emanating from
power plants, vehicles and fertilizers used in the agriculture could be a great
threat to biodiversity in many areas of the world. One of these areas is also Rocky Mountain
National Park where
scientists discovered that the elevated levels of nitrogen are already changing
the alpine vegetation.
Professor
William Bowman at the University
of Colorado said that the
spreading nitrogen pollution in the park is „a first step in a series of
changes which may be relatively irreversible.“
The
increased atmospheric nitrogen pollution has already resulted in changes in
plant abundances, which could eventually lead to high decrease of more rare
species leading to significant biodiversity loss. The scientists also fear that
the excessive levels of nitrogen pollution in Rocky Mountain
National Park will also
lead to acidified soils and a major decline in trout population.
The
nitrogen levels near the park are expected to grow, primarily because of the
increased agricultural development in nearby area.
The park attracts
many fishermen throughout the year and the fishing activity could be negatively
affected with the increased nitrogen pollution because this presents major
health risk for trout and their food sources. There is even a risk that nitrogen
pollution could negatively impact tourism in Colorado.
The state
of Colorado definitely needs to find adequate solutions
to prevent further increase of nitrogen pollution in Rocky Mountain
National Park. Some nearby
power plants have already switched to cleaner energy sources (Excel Energy) and
Colorado
agricultural industry is also said to be working on several management
practices that should lead to lower levels of nitrogen emissions.
