Name: Puccinellia nuttalliana Intermittently Flooded Herbaceous Alliance
Reference: Western Ecology Working Group of...
Description: Plant associations within this alliance are found in saline flats at lower to moderate elevations in the western United States. This alliance is known from salt flats in a large, high-elevation (2900 m) park in the Colorado Rocky Mountains, and possibly in basins (1500 m) in Nevada and South Dakota. Topography is generally flat with poor drainage. Soil moisture is augmented in some areas by groundwater. There is a small microtopography of hummocks which affects the water relations and therefore species composition. The soils are moist, saline and alkaline, derived from calcareous shales. The rain- and groundwater-saturated soils usually dry out during the growing season. These communities form a ring just above the succulent plant associations associated with playas, salt flats, and saline lakes. Puccinellia nuttalliana dominates the graminoid stratum with up to 65% cover. Distichlis spicata or Hordeum jubatum often codominate the graminoid layer. The forb layer is relatively sparse, typically only 30%. It can be composed of Salicornia rubra or Triglochin maritima.
