During earlier phases of research at the Woodward field station,
great attention was given to ornamental plants and windbreak plantings appropriate to the
Southern Plains. Although we no longer do this type of research, a large number of
interesting specimens still can be found here. Below is the text of a self-guided
tree tour available on the grounds of the SPRRS. This is not an exhaustive list of
the woody plants present here, but is intended to be an easily walked tour in the
immediate vicinity of the office building. There is an
accompanying map.
WELCOME
The USDA Southern Plains Range Research Station was established in 1914, and at
that time only two cottonwoods were present on the property. The large variety of trees
and shrubs present on the station today are the result of past areas of research which
have included tree and shrub investigations, windbreaks, dairy, fruit and vegetable,
sorghum, Weeping lovegrass, and Old World bluestem grass. Present research on the station
emphasizes various aspects of range research including studies on eastern gamagrass and
rangeland ecology and grazing management systems.
Plant materials collected from all over the world have been evaluated at Woodward for
their usefulness on the Southern Plains. Trees have been planted since the establishment
of the station, but the last major tree plantings were made around 1964. Due to this, many
of the tree plantings are showing their age.
Trees listed on the tour are labeled with a small green or yellow metal tag. The map on
the opposite side of this page shows the approximate location of the plants listed below
with a >+=

available.
