DOI PLACE HOLDER

Abstract:

This data package contains rabbit survey data from grassland and creosote shrubland habitats on Jornada Experimental Range (JER) and Chihuahuan Desert Rangeland Research Center (CDRRC) lands. Two survey routes were established along Jornada Basin roads in 1996; one in black grama grassland and the other in creosotebush shrubland. Quarterly surveys are conducted on these roads at or near the full moon to measure the density of rabbits in the two vegetation types. Each route is about 6 miles long. Parallel studies were established at the Sevilleta LTER site (New Mexico, USA) and Mapimi Biosphere Reserve (Durango, Mexico). Data collection began in April 1996 and includes date and time lagomorphs are spotted, species identification, habitat type, distance/direction from vehicle, and comments on the weather, moon, and anything unusual. This study is ongoing with new data collected quarterly.

Description:

Two rabbit survey routes were established along Jornada Basin roads in 1996; one in black grama grassland and the other in creosotebush shrubland. These routes were chosen to pass through habitat resembling the vegetation at grassland and creosotebush sites in the Small Mammal Exclusion Study. Quarterly surveys are conducted on these roads at or near the full moon to measure the density of rabbits in the two vegetation types. Each route is about 6 miles long.

Night-time road surveys are conducted during or near a full moon event (+/- 3 days) in winter (January/February), spring (April/May), summer (July/August), and autumn (October/November). The counts can be conducted during the full moon in either month of each season, depending on when the weather is best. The portion of road surveyed through the creosotebush environment (Route 1) runs 6.2 miles (9.98 kilometers) across the east bajada of the Dona Ana Mountains (dominated with creosotebush with scattered mesquite), from the USDA, JER south entrance on Jornada Road at the rock pillars, to the power-line road, past the C-GRAV and C-SAND sites, to the Weather Trailer gate. The grassland portion of the road (Route 3) runs 6.3 miles (10.14 kilometers) from South Well to USDA Pasture 13, along the west boundary of Pasture 13, then along the north boundary of Pasture 13 to Jornada Road at the "wind tunnel" site. One open bed pickup truck is driven approximately 12 miles per hour along each road route. The driver (data recorder) of the truck sets the trip odometer to zero at the start of each of the road segments (creosotebush and grassland). Two people (observers) in the back of the truck scan each side of the road for rabbits, each using a 100,000 candle-power spotlight. The observers shine the light beam in a 90 degree arc from the road ahead to the area perpendicular to the truck. The observers should watch for rabbits, and the reddish reflection of rabbits eyes in the light. Each time a rabbit is observed, the truck stops, and the observer guides the truck to a position perpendicular to the rabbit. The observer then calls out information to the driver who records the following information in the data book:

In addition, the data recorder must record the road mileage from the odometer for the START and END points as well as the mileage and time for the GATE that is passed through along each route. The terms START, END, and GATE are entered into the species field on the data sheet. At the start of each route, Comments must be made by the data recorder on the Moon Phase (full moon) at the beginning of the first route. Weather conditions (for example, scattered high clouds, mostly clear, no wind) should be commented on at the beginning and end of each route since wind and cloud cover conditions may change.

NOTE: Rabbit surveys are conducted only when the moon is full, the skies are mostly clear, and winds are light (< 10 mph).

NOTE: Bushnell Yardage Pro Compact 800 rangefinder (laser rangefinder) used beginning January 2002.

Abstract:

The Jornada Basin Long-Term Ecological Research (LTER) program is part of a national network of long-term ecological research sites funded by the US National Science Foundation (NSF). The Jornada LTER program has been continuously funded since 1982 to develop general principles governing changes between grassland and shrubland ecosystems based on long-term data collected in the Chihuahuan Desert. We translate our findings to dryland ecosystems around the world, and forecast the dynamics of future ecosystem states in response to changing climate and land use.

Funding:

JRN LTER is funded by the National Science Foundation under award DEB 2025166.
