vegetation. Significant environmental benefit (SEB) will be vegetation. Significant environmental benefit (SEB) will be provided to increase biodiversityprovided to increase biodiversity

• CriteriaCriteria– Periodic (at least annual) photographic evidence for Periodic (at least annual) photographic evidence for

specified photo monitoring sites will show no clearance of specified photo monitoring sites will show no clearance of native vegetation. If vegetation is cleared, SEB will be native vegetation. If vegetation is cleared, SEB will be provided in accordance with approved Native Vegetation provided in accordance with approved Native Vegetation Council guidelinesCouncil guidelines
