Bromus tectorum Semi-natural Herbaceous Alliance

accession code: VB.CC.28471.BROMUSTECTORUMS
|
Western Ecology Working Group of... |
3
|
This alliance is found throughout much of western North America from the western Great Plains to intermountain and southwestern U.S. Elevation ranges from sea level to 2200 m. It occurs after disturbance of a natural shrub- or grass-dominated community resulting in the replacement of the natural vegetation by non-native, annual grass species of Bromus. Bromus tectorum typically dominates the community with over 80-90% of the total vegetation cover, making it difficult to determine what natural community was formerly present. This alliance also includes grasslands dominated or codominated by other Eurasian introduced annual Bromus species such as Bromus hordeaceus, Bromus madritensis, Bromus japonicus, Bromus rigidus, or Bromus rubens, but is distinct from the annual Bromus communities found along the Pacific Coast with Mediterranean or maritime climates. |

Cercocarpus montanus Woodland Alliance

This alliance is latitudinally widely distributed, known from the valleys of northwestern California to montane habitats in the southern part of the state. Depending upon local moisture conditions and fire history, this vegetation can occur on ridges with stony, excessively drained soils or moist swales with fine soils and subirrigation. Vegetation is this alliance is characterized by the presence of tree-sized Cercocarpus montanus var. glaber in the upper canopy. Tree associates include many different species of Quercus, Juniperus, and Pinus depending on location. The shrub layer is variable in density and species composition. Characteristic shrubs include several species of Ceanothus and Arctostaphylos, Adenostoma fasciculatum, Artemisia tridentata, Eriogonum fasciculatum, Frangula californica (= Rhamnus californica), Garrya fremontii, Purshia tridentata, Rhamnus ilicifolia, Quercus garryana var. breweri, and Quercus berberidifolia. Diagnostic of this woodland alliance is the presence of large (>5 m tall) Cercocarpus montanus var. glaber codominating the tree canopy. |

NY Heritage: Highbush blueberry bog thicket

Ecological Communities of New York, 2nd Ed. |

An ombrotrophic or weakly minerotrophic peatland dominated by tall, deciduous, ericaceous shrubs and peat mosses (Sphagnum spp.); the water is usually nutrient-poor and acidic.
The dominant shrub is usually highbush blueberry (Vaccinium corymbosum). At least three regional variants are recognized in New York. The first is found throughout central and western New York, the second is primarily a northern variant, and the third is a southern variant with coastal plain species.
Species characteristic of all three varieties, and typical of the central and western New York examples, include highbush blueberry (Vaccinium corymbosum), winterberry (Ilex verticillata), cinnamon fern (Osmunda cinnamomea), marsh fern (Thelypteris palustris), and Sphagnum spp. Stunted trees may be present at a low density and with less than 50% cover; red maple (Acer rubrum) occurs in many bog thickets. Other characteristic shrubs and herbs include black huckleberry (Gaylussacia baccata), false Solomon's-seal (Smilacina trifolia), and pitcher plant (Sarracenia purpurea).
Additional characteristic species in northern examples include mountain holly (Nemopanthus mucronatus) which may be codominant, sedge (Carex trisperma), and calla (Calla palustris). Scattered small small trees include tamarack (Larix laricina), black spruce (Picea mariana), and white pine (Pinus strobus).
The southern New York variant of this community contains substantially fewer northern taxa and numerous coastal indicator species such as swamp azalea (Rhododendron viscosum) which may become codominant, red chokeberry (Aronia arbutifolia), male-berry (Lyonia ligustrina), fetterbush (Leucothoe racemosa), sweet pepperbush (Clethra alnifolia), water willow (Decodon verticillatus), buttonbush (Cephalanthus occidentalis), marsh St. John's-wort (Triadenum virginicum), sedges (Carex trisperma, C. striata), three way sedge (Dulichium arundinaceum), and Virginia chain fern (Woodwardia virginica). Scattered small trees may include pitch pine (Pinus rigida) or Atlantic white cedar (Chamaecyparis thyoides) (MacDonald and Edinger 2000; Damman and French 1987).
Communities on Long Island with similar vegetation (i.e., dominated by tall shrubs such as Vaccinium corymbosum, Leucothoe racemosa, Clethra alnifolia, and Chamaedaphne calyculata) with shallow peat deposits (<20 cm) are treated as pine barrens shrub swamps. The two natural communities are separated by the fact that highbush blueberry bog thicket maintains a persistent hydrological regime, supports peat development, and often lacks "edge species" that are found in pine barrens shrub swamp, such as Lyonia mariana, Ilex glabra, and Myrica pensylvanica.
Characteristic peat mosses for all variants include Sphagnum magellanicum, S. centrale, S. capillifolium, and S. fimbriatum. Characteristic animals include common yellowthroat (Geothlypis trichas), swamp sparrow (Melospiza georgiana), song sparrow (Melospiza melodia), meadow jumping mouse (Zapus hudsonius), masked shrew (Sorex cinereus), southern red-backed vole (Clethrionomys gapperi), and green frog (Rana clamitans). |
