Final answer:
Indicators of non-inundated wetlands include hydrophytic vegetation adapted to grow in water-saturated soils, hydric soils that are characterized by water saturation and anoxic conditions, and a topography suggestive of regular water saturation.
Step-by-step explanation:
Hydrologic indicators other than water that help identify wetlands that are not currently inundated include several key features. These features are indicators of a wetland environment, even when water is not visibly present on the surface. One primary indicator is hydrophytic vegetation, which consists of plant species adapted to grow in water-saturated soils. These plants often have certain traits, such as aerenchyma, that help them survive in such conditions. Another indicator is the presence of hydric soils, which are permanently or seasonally saturated by water, resulting in anoxic conditions that are evident by their distinctive soil colors and textures. Additionally, wetlands may exhibit a certain topography that implies regular water saturation, such as shallow depressions.
