Name:
Quercus alba - Carya ovata / Carex pensylvanica - Heuchera richardsonii Quartzite Glade Woodland
Reference:
NatureServe Biotics 2019
Description:
This quartzite woodland is found on rocky, hilly regions in the upper midwestern United States, particularly in the Baraboo Hills of Wisconsin. Stands occur on the brow of steep slopes that overlay quartzite, rhyolite or sandstone bedrock that contains some fractures. The stands themselves have gently slopes (2-11%), mostly with a southwestern aspect, but ranging from due east to due west. Glade soils are thin (10-30 cm deep) silt loams, acidic (pH of 4.5-5.0), fertile, and rich in organic matter (10-15% organic matter). These glades represent forest openings dominated by relatively even-spaced, small-statured trees and a sparse shrub and sapling layer. The tree canopy is fairly closed, averaging about 75% (range of 57-82%). Either <i>Quercus alba</i> or <i>Carya ovata</i> dominate the canopy. <i>Quercus velutina</i> and <i>Quercus rubra</i> are much less common. Shrubs are nearly absent from all glades, with <i>Ribes</i> spp. and <i>Viburnum rafinesqueanum</i> the more common species. The most abundant saplings are <i>Fraxinus pennsylvanica, Ostrya virginiana</i>, and <i>Quercus rubra</i>. Excluding tree seedlings, the ten most common understory species found in these glades are <i>Carex pensylvanica, Antennaria plantaginifolia, Poa compressa, Anemone quinquefolia, Solidago ulmifolia, Maianthemum racemosum, Heuchera richardsonii, Dodecatheon meadia, Geranium maculatum</i>, and <i>Helianthus strumosus</i>. No vascular plant species were restricted in distribution to the glades but several may be modal within the context of Wisconsin, including <i>Carex pensylvanica, Heuchera richardsonii, Antennaria plantaginifolia, Solidago ulmifolia, Lespedeza virginica, Lespedeza violacea</i>, and <i>Agalinis gattingeri</i>.
