Local Cedar Glade


Today I visited a local cedar glade for the first time.  I was expecting to find many of the important prairie grasses and associated forbs at this site since it appeared to be in an ideal location, surrounded by forest on a difficult to access slope.  I assumed that such isolation would would ensure unsual or rare native plants would abound.   Unfortunately this was not the case.  The glade habitat appeared depauperate from past land use.  The glade was surrounded by barbed wire and had been used as pasture many decades ago.  Exotic grasses such as, timothy, canada bluegrass, kentukey bluegrass, Bromus tectorum and orchard grass have invaded and persisted since this area was pastured.  Simalarly exotic forbs like oxeye daisy, viper's bugloss, spotted knapweed were detected.

Poverty oatgrass, a native grass was by far the most abundant graminoid.  Dichanthlium acuminatum, D. linearifolium, Andropogon virginicus and Tridens flavus were also present. 


These pleasant woodlands developed atop the slope.  The grass cover here is a mixture of virginia wildrye, orchardgrass and bottlebrush (listed in decreasing abundance).  Tree species included black walnut, eastern redcedar and honey locust.


In areas of sparse vegetation reindeer moss (Cladonia sp.) thrives.  The blue flowered plant is viper's bugloss (Echium vulgare) a exotic weed that seems particularly suited to these dry, sunny, limestone sites.


Monarda fistulosa was the most abundant native forb at this site.  None of these plants seemed to exhibit the densely hairy leaves and petioles found on the big hollow plants.

A XLP along Spring Creek


This high quality priairie remnant has persisted on a small powerline right of way.  The site is small in size covering approximently 5000 square feet.  While casual botanical surveys of the site have yet to reveal any state listed species, the site is remarkabley free of troublesome exotic herbaceous plants like spotted knapweed, ox eye daisey, sweet clovers and crown vetch which plague that majority of the states limestone prairie remnants.  Even the the woody plant species invading the grassland is composed mostly of native plants, such as, Yellow oak, fragrant sumac, black walnut, ash and ironwood (dominant).  The problematic Morrow's and Amur honeysuckles are present at this site as well as autumn olive albeit in small amonts.

Below is a list of some of the native species observed at this site.

Graminoids:
Sorgastrum nutans
Andropogon gerardii
Schizachyrium scoparium
Bouteloua curtipendula
Danthonia spicata
Carex spp.

Forbs:
Hepatica sp.
Blephilia ciliata
Zizia aptera
Pycnanthemum incanum
Calystegia spithamaea
Monarda fistulosa var. mollis
Monarda clinopodia
Mianthemum racemosum
Uvularia spp.
Helianthus spp.
Lespedeza spp.
Solidago juncea
Solidago nemoralis
 Allium cernuum

Woody plants (within grassland area):
Quercus muhlenbergii
Quercus alba
Fraxinus sp.
Rhus aromatica
Ostrya virginiana
Juniperus virginiana
Ceanothus americana
Tilia americana

Plus many other species.  I hope to eventually get the time to completely survey the grassland.

A recent visit revealed many Rosa carolina plants in bloom
Another large flowered plant currently in bloom is Calystegia spithamaea
Blephilia ciliata
