Final answer:
The project boundary when certifying a site includes the 'Project limits' which encompasses the designated area and specified premises critical for project execution and conservation.
Step-by-step explanation:
When certifying a site, the project boundary includes the 'Project limits,' which refers to the specified premises that have been outlined for the particular project. The designated area, site surroundings, and any delineated areas where local resources may be extracted are all encompassed within these project limits. More specifically, key biodiversity areas are delineated based on existing land management units and are designed to factor in global standards while fostering local conservation efforts. The project limits are essential for ensuring that all relevant environmental factors, resources, and stakeholder interests are considered in the certification process.
