True or False: Mechanical methods of maintaining ROWs are non-selective and can disrupt environmentally sensitive sites.

Mechanical methods of maintaining Rights-of-Way (ROWs) are indeed considered non-selective and can significantly disrupt environmentally sensitive sites. This is due to the nature of mechanical techniques such as mowing, cutting, or brushing, which do not differentiate among the various plant species present in the area. When using mechanical methods, there is a high likelihood that both desirable and undesirable plants will be affected, potentially leading to unintended consequences for local ecosystems.

In environmentally sensitive areas, such as wetlands or habitats supporting endangered species, this indiscriminate approach can cause habitat destruction and reduce biodiversity. Therefore, the assertion that these methods can disrupt environmentally sensitive sites aligns with the principles of vegetation management and ecological conservation.

The other choices, while they may encompass considerations about specific situations or conditions, do not capture the broad impact that mechanical methods can have on sensitive environments. Thus, recognizing the non-selective nature of mechanical maintenance methods underscores the need for careful planning and consideration when applying such techniques in diverse ecological contexts.
