| Abstract: |
| Prairie dogs are keystone species that impact both animals and plants in grassland
habitats. They are a food resource for secondary consumers such as badgers, foxes,
and raptors. Also, the mounds that they construct are home to many arthropod and reptile
species that otherwise might not survive in grasslands. Both Gunnison’s and black-tailed
prairie dogs can increase the number of plant species in grasslands and landscape
heterogeneity with their ecosystem engineering that creates disturbed patches on the
landscape. Gunnison’s prairie dogs, which were native herbivores at the Sevilleta
National Wildlife Refuge (NWR) before their populations disappeared, were reintroduced
at the Sevilleta NWR in 1997, 2005, and 2008. In 1998, a Gunnison’s prairie dog
colony naturally established along the northern border on the east side of the Refuge.
The naturally occurring colony and the colony that was reintroduced in 1997 have since
then severely declined or gone locally extinct. Still, with the removal of cattle
from the Sevilleta in 1973, the reintroductions of Gunnison’s prairie dogs in 2005
and 2008 provides an interesting opportunity to study how a native keystone herbivore
affects a grassland habitat without the pressures and competition from livestock.

| Description: |
| Data were qa/qced and obvious errors were corrected. A column for height was added
to the data since we added to the protocol a height measurement in 2009. We also added
in 2008 prairie dog fecal counts and in 2009 prairie dog disturbance measurements.
Previous data were explored to renter past height measurements along with adding disturbance
and prairie dog fecal pellet counts to the data. These measurements were not recorded
for all years. 11 January 2010 tlk

| Method Step: |
| Description: |
| Experimental Design Three psuedo-replicates in a paired plot design: 1)plots where
prairie dogs have been reintroduced and 2)control plots.Sampling Design Each 100 x
100m plot contains 36 sample units (quads) that are 20m apart in a 6 x 6 grid. These
quads are numbered in a zig zag pattern starting in the NE corner of the plot where
the first six quads go north to south, the next six plots that are west of the first
quads go south to north, and so on for the remaining quads on the plot. These quads
are marked by a numbered rebar stake.Field/laboratory Procedures A 50 x 50 cm quadrat
separated into twenty-five 10 x 10 cm squares are placed southeast of a small white
pvc pipe that marks permanent subplots. Then, percent covers and highest height are
estimated for each plant species into palmtop computers. Species occupying less than
1%, a quarter of a 10 x 10 cm square, are recorded 0.1 %. When estimating plant species
percent covers yellow and green plant material are included in the measurement. Individual
plants that are completely gray, containing no yellow or green foliage, are not assessed
in the percent cover estimate. For highest height, the ‘average’ height of the
foliage for perennialspecies is recorded and for annual plant species the height to
the top of the inflorescence, flowers and fruits,is recorded. The estimate of percent
cover of disturbance from prairie dogs is the same as the plant cover estimates. Finally,
all prairie dog fecal pellets that are in the quadrat, subplot, are counted.
