The surface expression of groundwater, from the Evergreen and/or Precipice geological formations, takes the form of a vegetated spring in the Lucky Last spring complex, Queensland. Discharge of groundwater may provide habitat for endemic plants and aquatic species

The surface expression of groundwater, from the Precipice geological formation, takes the form of a watercourse spring. This baseflow may support aquatic and terrestrial ecosystems downstream of the discharge point or points.

The surface expression of groundwater takes the form of a vegetated spring. Discharge of groundwater may provide habitat for threatened ecological communities, those communities of species dependent on groundwater discharge from the Great Artesian Basin. This photo shows one of the members of a threatened ecological community, the wolf spider from the family Lycosidae
