Ponderosa Pine Woodland
This community occupies 93 acres (6%) and is most often associated with seasonal creeks,
although small patches are scattered over more variable terrain. Stands typically consist of widely
scattered ponderosa pine with shrubs clustered around the tree bases and open grassland
between trees. The principal tree and shrub species in this community are ponderosa pine,
Gambel oak, and three -leaf sumac (Rhus trilobata). Rocky Mountain juniper occurs scattered in
some stands. Other shrub species present include poison ivy (Toxicodendron rydbergil), currant
(Ribes sp.), and in stands near riparian woodland, chokecherry (Prunus virginiana). In the
northern third of the property, Douglas fir occurs scattered in this community. Principal forbs
include wild tarragon (Artemisia dracunculus) and fringed sage (Artemisia frigida), with associated
giant hyssop (Agastache sp.), yarrow (Achillea millefolium), pussytoes, and Bigelow's gentian
(Gentiana bigelovii). The principal grass is blue gramma (Bouteloua gracilis), with associated
brome (Bromus sp.) and needle and thread (Hesperostipa comata). Average cover and height
estimates for the principal plant species in this community are provided in Table 2.

Pinyon -Juniper Woodland

ridgelines, and south -facing slopes. Principal tree species are moderately dense Rocky Mountain
juniper, one -seed juniper (Juniperus monosperma), and pinyon pine (Pinus edulis). Rocky
Mountain juniper is generally more common than one -seed juniper, except in some areas in the
southern two-thirds of the property where one -seed predominates. Pinyon pine is most common
