What is a typical feature of the erosion layer in a final cover system?

A typical feature of the erosion layer in a final cover system is that it must be capable of sustaining native plant growth. This aspect is essential because the erosion layer plays a critical role in promoting vegetation, which helps to stabilize the soil against erosion while also providing habitat for local wildlife. The vegetation aids in absorbing rainwater and reduces surface runoff, thereby further minimizing erosion.

In a well-designed final cover system, the growth of native plants not only supports the ecosystem but also contributes to effective water management and enhances the landscape's aesthetic appeal. The presence of vegetation can also assist in the degradation of any remaining organic materials in the landfill by promoting microbial activity, which is beneficial for the long-term closure and sustainability of the landfill site.
