What should be verified about amendments, mulches, and soils before bringing them to a site?

Verifying that amendments, mulches, and soils are free from harmful pests is crucial because introducing contaminated materials can lead to the spread of invasive species, pests, or diseases that can harm native flora and fauna. Maintaining ecosystem health is a priority in right-of-way management, and ensuring that any materials brought onto a site do not carry pest or disease organisms is a key preventative measure. This action helps protect not only the immediate area but also surrounding landscapes from potential infestations or health issues caused by non-native pests.

While enhancing nutrient levels, ensuring economic viability, and sourcing materials locally are important considerations, they do not directly address the immediate risks associated with bringing potentially harmful organisms to a site. Prioritizing pest and disease-free materials safeguards the environment, which is critical in any management or restoration effort.
