Name: Picea pungens / Poa pratensis Ruderal Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This association is found in the Pecos and Rio Grande basins of north-central New Mexico. Preliminary data suggest that it occurs on high, flat terraces of narrow montane streams. Terrace formation is usually between low riverbars and higher, drier, upland hillslopes. Soils of this type are loamy and silty over a gravelly-cobbly matrix. Soils have high plant-available water, and they can have wetness (hydric) indicators, but these are deep in the soil profile. On sites near the active stream channels, soils can be relatively moist (coarse-silty Oxyaquic Ustifluvents); others are drier and more developed (Fluventic Dystrochrepts), particularly on older terraces. Most sites are estimated to flood infrequently (75- to 100-year flood-recurrence interval). The type is known to occur at upper elevations ranging between 2350 and 2775 m (7725-9100 feet). It is characterized by an open canopy of <i>Picea pungens</i> with a grassy understory dominated by <i>Poa pratensis</i>, with only scattered, if any, shrubs. Overall species diversity is moderately high with 67 species recorded for the type, of which 14 are introduced exotics, and 12 are native wetland indicators.
