Vulnerability Ratings

Do you remember the four categories of karst vulnerability from Lesson 2?

Low
Moderate
High
Very High

Are there any vulnerability categories where timber harvesting is not recommended?

Karst areas classified as very high vulnerability contain sensitive, high resource values. In most cases, it is recommended that very high vulnerability areas be excluded from harvesting operations. Limited exceptions to this may occur in special situations where some form of site-specific intervention is required to help protect forest or karst resources (e.g., forest health issues such as insect infestations). Any forest management activities that may be required on very high vulnerability karst areas should be conducted in consultation with a karst specialist, the Forest Service, and/or other relevant resource agencies.

On which vulnerability categories are harvesting operations recommended?

Harvesting operations will generally occur on low, moderate, and high vulnerability karst areas. As the level of karst vulnerability increases, so do the protective measures of the recommended best management practices.

How are the recommended best management practices linked to the assessed vulnerability of the karst?
