Improve forest management practices
Forest management practices that maintain healthy forests are essential for protecting ecosystems, public health, and air quality. Here are some ways to improve forest management practices to decrease pollution in national parks:
Prescribed Burns
Prescribed burns, or controlled fires, are a well-recognized forest management practice. Due to modern forest management practices and the expansion of the wildland-urban interface (WUI), fires have been unnaturally suppressed for decades. This has led to an overstocking of trees, making forests more susceptible to drought, disease, insects, high tree mortality, and wildfires. Prescribed burns help restore natural regeneration processes and reduce vegetation buildup, which can fuel wildfires. While they produce local air pollution, prescribed burns ultimately contribute to ecosystem health and more manageable wildfires.
Wildfire Prevention Strategies
With wildfires becoming increasingly frequent and severe due to climate change, implementing wildfire prevention strategies is crucial. This includes education about fire-safe activities, as most wildfires result from human irresponsibility. Additionally, creating fire breaks, or open areas cleared of vegetation and debris, can help prevent the spread of wildfires.
Tree Planting and Maintenance
Planting fire-resistant, drought-resistant, and rot-resistant tree species can enhance the resilience of forests to wildfires, water scarcity, and disease. Focusing on diverse species rather than monoculture plantations can further strengthen the ecosystem. Tree thinning, or removing dead or diseased trees, also creates more space between existing trees, reducing the risk of fire spread and improving forest health.
Air Quality Monitoring
Establishing resilient air quality monitoring networks is vital for understanding how wildfires and poor air quality impact national parks. The National Park Service (NPS) participates in several such networks, measuring ozone, visibility, particulate matter, nitrous oxides, sulfur dioxide, and mercury. These networks help the NPS assess air quality levels in individual parks and identify nationwide trends.
Collaboration with Stakeholders
The National Park Service should collaborate with air regulators, developers, and other stakeholders to reduce air pollution, as most pollution in national parks originates from outside their boundaries. This collaborative approach can positively impact both the parks and nearby communities.
By implementing these improved forest management practices, we can work towards preserving the health of our national parks and protecting the air quality that visitors and surrounding communities depend on.

Implement wildfire prevention strategies
As wildfires become increasingly common due to climate change, implementing wildfire prevention strategies is essential to protecting ecosystems, public health, and air quality in national parks. Here are some ways to implement wildfire prevention strategies to decrease pollution in national parks:
Public Education and Awareness:
The public can play a crucial role in preventing wildfires, as human activities are responsible for a significant majority of wildfires. Educating visitors and nearby communities about wildfire prevention is essential. This includes raising awareness about proper campfire practices, such as completely extinguishing campfires by dousing them with water and ensuring they are cold to the touch before leaving. Additionally, promoting safe practices for burning debris, such as having water nearby and avoiding burning during windy conditions, can help prevent wildfires.
Vehicle Maintenance:
Vehicles and equipment can sometimes spark wildfires due to high exhaust temperatures. Educating the public about maintaining their vehicles properly and avoiding driving or parking over dry grass can help reduce the risk of wildfire ignition.
Collaboration with Fire Management Agencies:
The National Park Service (NPS) should collaborate with state and national fire management agencies, such as the National Wildfire Coordinating Group, to develop and implement comprehensive wildland fire management programs. These agencies provide valuable resources, guidelines, and policies to help the NPS effectively plan, respond to, and manage wildland fires.
Fire Management Plans:
Developing and adhering to fire management plans is crucial for national parks. These plans should be guided by existing planning documents, such as general management plans and resource stewardship strategies. Fire management plans should include strategies for preventing, responding to, and managing wildfires, ensuring that the workforce is well-trained and equipped to handle wildfire incidents.
Monitoring Weather Conditions:
Paying close attention to weather and drought conditions is essential for wildfire prevention. Understanding the flammability of vegetation due to weather conditions can help park managers and visitors alike make informed decisions to prevent wildfires.
By implementing these wildfire prevention strategies, national parks can reduce the risk of wildfires, thereby preserving the natural landscapes, protecting ecosystems, and improving air quality for the benefit of both visitors and the surrounding communities.

Strengthen clean air and climate laws
Strengthening clean air and climate laws is essential to decrease pollution in national parks and protect the health of both visitors and the environment. The Clean Air Act (CAA), a critical piece of legislation, has been instrumental in improving air quality across the nation and within the National Park System. It has special provisions aimed at restoring healthy, clear air to national parks, which are designated as Federal Class I areas.
However, there is a growing recognition that existing laws need to be strengthened to address persistent pollution issues. The National Parks Conservation Association (NPCA) plays a pivotal role in this regard, advocating for stronger clean air and climate laws and regulations. They work to hold polluters and government agencies accountable, emphasizing the need to put people first. Their efforts have resulted in significant reductions in visibility-impairing pollution, the closure and cleanup of coal plants polluting parks, and the elimination of millions of metric tons of climate pollution.
The NPCA's Clean Air Team, for instance, focuses on strengthening laws and regulations to address pollution sources such as fossil fuel facilities, industries, and vehicles. They also advocate for strong national air standards and the enforcement of rules to limit haze-causing and climate-altering pollution.
Additionally, the Regional Haze Rule, mandated by the Clean Air Act, is another crucial tool in the fight against pollution in national parks. It aims to improve air quality and visibility in Class I areas, including national parks. The rule targets emissions that contribute to haze, such as sulfur dioxide, and has led to significant improvements in visibility and health in national parks.
To further strengthen clean air and climate laws, collaboration is essential. The National Park Service must work closely with air regulators, developers, and other stakeholders to implement effective policies. This collaborative approach not only benefits the parks but also positively impacts the nearby communities.
In conclusion, strengthening clean air and climate laws is a critical aspect of reducing pollution in national parks. Through the efforts of organizations like the NPCA, the enforcement of regulations like the Clean Air Act and the Regional Haze Rule, and collaborative partnerships, we can make significant strides towards ensuring clean air and a healthy climate for our national parks and all who enjoy them.

Reduce waste and promote composting
Visitors are the primary source of waste in national parks, so it is important to assess and improve services to reduce waste. One of the most effective ways to reduce waste is to promote composting programs, which can also help reduce greenhouse gas emissions and mitigate climate change.
The National Park Service (NPS) has implemented several initiatives to reduce waste, such as the Zero Landfill Initiative, which aims to eliminate garbage within parks. As part of this initiative, Grand Teton National Park manages its compost at a commercial scale and uses dumpsters and trucks to manage the volume. The park has also provided extensive training to its employees on zero landfill initiatives, including recycling and composting education.
Yosemite National Park has also implemented a successful composting program in collaboration with various partners, including the National Park Service, Mariposa County, Nature Bridge, and others. The park has added ten new bins since 2015, and through both the Zero Landfill Initiative and its composting program, 19 million pounds of waste have been reduced.
Denali National Park & Preserve has also made significant strides in waste reduction, introducing triple-bin recycling containers, upgrading recycling equipment, and implementing composting programs. As a result, they have seen a notable increase in their diversion rate and a decrease in waste sent to local landfills.
Composting may not always provide a sanitary output and might require additional processing to produce a usable product. Anaerobic digestion is a "greener" alternative that produces renewable energy as biogas and requires less energy to operate. However, potential odors and detrimental wildlife impacts must be considered and mitigated with enzyme spray applications and containment.
