Center for Native Grasslands Management
-
The Center for Native Grasslands Management provides a scientific background to producers and land managers, enabling them to effectively establish and manage native grasslands. The Center’s second major focus is to make findings from our research widely available throughout the eastern United States. We work through Extension and partner organizations to share these results with producers, land management agencies, other researchers, and wildlife conservation organizations through publications, workshops, trainings, and field days.

Native Grass College: Video series
-
The Native Grass College offers short videos and resources for practitioner and landowners to learn how to 1) Establish Native Grasses, 2) Control Grass Competition, and 3) Manage grazing. Native grasses are better for grazing and for wildlife. Developed by Dr. Pat Keyser, Center for Native Grasslands Management at the University of Tennessee.

Map of NRCS States Opting In/Out of WLFW Northern bobwhite
-
In February 2021, NRCS requested that 30 state offices within the northern bobwhite current or historic range submit a final decision to National Headquarters on opting in or out of WLFW Northern bobwhite, Grasslands and Savannas. The decisions were completely voluntary and dependent on each states interest and ability to commit. These maps depict the distribution of states and their responses. Note that Oklahoma has now joined (and we need to updated this map)!

Worldwide evidence of a unimodal relationship between productivity and plant species richness
-
The search for predictions of species diversity across environmental gradients has challenged ecologists for decades. The humped-back model (HBM) suggests that plant diversity peaks at intermediate productivity; at low productivity few species can tolerate the environmental stresses, and at high productivity a few highly competitive species dominate. Over time the HBM has become increasingly controversial, and recent studies claim to have refuted it. Here, by using data from coordinated surveys conducted throughout grasslands worldwide and comprising a wide range of site productivities, we provide evidence in support of the HBM pattern at both global and regional extents. The relationships described here provide a foundation for further research into the local, landscape, and historical factors that maintain biodiversity.

Aeolian process effects on vegetation communities in an arid grassland ecosystem
-
Many arid grassland communities are changing from grass dominance to shrub
dominance, but the mechanisms involved in this conversion process are not completely
understood. Aeolian processes likely contribute to this conversion from
grassland to shrubland. The purpose of this research is to provide information
regarding how vegetation changes occur in an arid grassland as a result of aeolian
sediment transport. The experimental design included three treatment blocks, each
with a 25 × 50 m area where all grasses, semi-shrubs, and perennial forbs were
hand removed, a 25 × 50 m control area with no manipulation of vegetation cover,
and two 10 × 25 m plots immediately downwind of the grass-removal and control
areas in the prevailing wind direction, 19◦ north of east, for measuring vegetation
cover. Aeolian sediment flux, soil nutrients, and soil seed bank were monitored on
each treatment area and downwind plot. Grass and shrub cover were measured on
each grass-removal, control, and downwind plot along continuous line transects as
well as on 5 × 10 m subplots within each downwind area over four years following
grass removal. On grass-removal areas, sediment flux increased significantly, soil
nutrients and seed bank were depleted, and Prosopis glandulosa shrub cover increased
compared to controls. Additionally, differential changes for grass and shrub
cover were observed for plots downwind of vegetation-removal and control areas.
Grass cover on plots downwind of vegetation-removal areas decreased over time
(2004–2007) despite above average rainfall throughout the period of observation,
while grass cover increased downwind of control areas; P. glandulosa cover increased
on plots downwind of vegetation-removal areas, while decreasing on plots downwind
of control areas. The relationships between vegetation changes and aeolian
sediment flux were significant and were best described by a logarithmic function,
with decreases in grass cover and increases in shrub cover occurring with small
increases in aeolian sediment flux
