Which of the following is a requirement for tree cutting in Zone 1 (0-10 ft)?

In tree cutting regulations for Zone 1, which extends from 0 to 10 feet, the requirement emphasizes the protection of high-value trees. High-value trees are typically those that provide crucial ecological benefits, such as stabilization of streambanks, habitat provision, or aesthetic value. Option B correctly states that only high-value trees that are not located on streambanks may be harvested. This is significant because streambank trees play a critical role in preventing erosion and maintaining water quality, and therefore, cutting these trees could have detrimental environmental impacts.

The focus on restricting the cutting of high-value trees helps ensure the preservation of crucial habitats and the protection of water resources. Proper management in this zone seeks to balance ecological health with forestry practices, which is why this choice is the correct answer. The other options incorrectly imply broader allowances for tree cutting that could compromise the integrity of the ecosystem, which is not permissible in this sensitive area.
