Wet conditions exist on poorly drained soils, often with a high clay content. Moist - Areas where the soil is damp. Occasionally, the soil is saturated and drains slowly. These areas usually are at slightly higher elevations than wet sites. Moist conditions may exist in sheltered areas protected from sun and wind.
Moisture is available to plants most of the growing season.
Soils usually are medium textures with enough sand and silt particles to allow water to drain through the soil. Dry - Areas where water drains rapidly through the soil. Soils are usually coarse, sandy, rocky or shallow. Slopes are often steep and exposed to sun and wind. Water runs off quickly and does not remain in the soil.
