Climate Change and Air Pollution in Big Bend National Park

Big Bend National Park is not only facing the challenges of climate change but also the detrimental effects of air pollution. Located downwind of major pollution sources, the park is particularly susceptible to air pollution, which has significant impacts on its delicate ecosystems.

Nitrogen and sulfur compounds, deposited from the air, can disrupt ecosystem processes and integrity within the park. These compounds have adverse effects on vegetation, soil quality, and water resources, altering the delicate balance of the ecosystem. The high sensitivity of Big Bend National Park’s ecosystem to nitrogen and sulfur deposition further exacerbates the consequences of air pollution.

Two primary outcomes of nitrogen and sulfur compounds in the park are acidification and eutrophication. Acidification occurs when these pollutants lower the pH of water bodies, negatively affecting aquatic life and habitats. Eutrophication, on the other hand, refers to the excessive enrichment of nutrients in water, leading to imbalances that disturb native species and disrupt the overall ecosystem functioning.

Impacts of Excess Nitrogen on Ecosystems

Excess nitrogen deposition can have detrimental effects on ecosystems in Big Bend National Park. The native vegetation in the park is not adapted to high nitrogen levels, which can lead to the displacement of native species by invasive plants like cheatgrass. Cheatgrass, which rapidly takes up nitrogen and spreads quickly, alters the composition of plant communities. This increase in non-native species disrupts the balance of the ecosystem and negatively impacts biodiversity. Additionally, excess nitrogen contributes to nutrient enrichment, causing some species to grow more quickly and altering the overall ecosystem structure.

Ecosystem Response to Excess Nitrogen

The introduction of excess nitrogen into an ecosystem can trigger various ecological responses. One significant outcome is the invasion of non-native plant species, such as cheatgrass, which outcompetes native vegetation. Cheatgrass (Bromus tectorum) is an invasive grass that thrives in high-nitrogen environments. It has a much higher growth rate compared to native plants, rapidly spreading and forming dense stands that dominate the landscape.

In addition to cheatgrass, other invasive species may also establish a foothold in response to excess nitrogen levels. These invaders disrupt the natural balance of the ecosystem and can lead to reduced biodiversity and ecological integrity. The altered species composition and dominance of non-native vegetation have cascading effects on other organisms within the ecosystem, including animals that rely on native plants for food and habitat.
