Name: Pinus ponderosa / Forestiera pubescens Riparian Woodland
Reference: NatureServe Biotics 2019
Description: This association is only known to occur at Bandelier National Monument in north-central New Mexico. The current description is based on data received from there and will be updated when additional inventory data are available. This riparian association occurs at elevations between 1660 and 2035 m (5450-6675 feet) along canyon bottoms with low to moderate solar exposure. Stands occur on alluvial terraces and bars adjacent to perennial stream channels with gradients between 5 and 10% (in a few cases, stands are found along moist ephemeral or intermittent channels). Soils are mapped as loamy Mollisols derived from latite, dacite, and rhyolitic alluvium, or simply as rock outcrop. The ground surface is characterized by shrubs rooted in exposed gravels and soil intermixed with grass and litter patches. This mixed broadleaf and conifer riparian forest is dominated by <i>Pinus ponderosa</i> with broadleaf deciduous riparian trees such as <i>Acer negundo</i> or <i>Populus angustifolia</i> as codominants that form open to closed canopies (10-80% canopy cover). <i>Juniperus monosperma</i> or <i>Juniperus scopulorum</i> along with <i>Alnus incana ssp. tenuifolia</i> or <i>Betula occidentalis</i> can be found in the subcanopy or as understory shrubs. The shrub layer is characterized by abundant <i>Forestiera pubescens</i> with a mix of other mesic shrubs and vines such as <i>Brickellia californica, Ptelea trifoliata, Rhus trilobata, Ribes leptanthum, Robinia neomexicana, Rosa woodsii, Rubus parviflorus, Toxicodendron rydbergii</i>, and <i>Vitis arizonica</i>. The herbaceous layer is a rich assortment of mesic-trending species (26 graminoids and 35 forbs) but variable in composition and cover (5-30% total cover). Common species include facultative and obligate wetland species such as <i>Agrostis exarata, Agrostis stolonifera, Carex hystericina</i>, and <i>Juncus dudleyi</i> among graminoids, and <i>Aralia racemosa, Berula erecta, Brickellia brachyphylla, Equisetum arvense, Lobelia cardinalis, Prunella vulgaris</i>, and <i>Rudbeckia laciniata</i> among forbs.
