Researchers found that improved roads convert natural habitats to roadside areas, allowing non-native weeds to spread into adjacent ecosystems. In contrast, native plants thrive closer to roads with typical grassland soils.
A study found that 20% of all land area in the US is within 127 meters of a road, while 50% is within 382 meters. This highlights the significant ecological impact of roads on forest ecosystems.
A study found that road improvement leads to significant increases in non-native plant cover, favoring invasive species. Cheatgrass and other weeds spread more along paved roads than primitive roads, converting natural habitat to roadside habitats.
The study found that roads, damage to tundra, and animal population decline are significant concerns. The report concludes that a balance must be reached between economic development and environmental protection in the North Slope region.
A new web-based system is being tested to improve winter road treatment.
