Abstract: 

This data set consists of periodic size measurements of permanently marked individual fluff grass plants. Measurements were taken in March, July, and September 1986.

Twenty 6 x 6 m plots were established with a 3 m buffer between plots. Five plots were randomly assigned to one of four treatments: (1) chlordane amendment 100ml AI (active ingredients) per 10,000 ml) to exclude microarthropods, (2) sprinkler irrigation (6 mm per week), (3) sprinkler irrigation (6 mm/week) plus chlordate amendment (as above), (4) control (no treatment). Three randomly located subsamples were taken from each plot.

Data file information for the following Jornada data set: Fluff grass plant growth

Methods: 

field data sheets

At each sampling date two diameters and one height were measured from permanently marked fluff grass plants (15 plants in each of 20 plots).

Additional information: 

This study was conducted in the Jornada del Muerto Basin on the NSF Long-Term Ecological Research (LTER) site, located on the New Mexico State University College Ranch 40 km NNE of Las Cruces, Dona Ana County, New Mexico. The site lies on an alluvial piedmont (bajada) sloping from west to the east and north. The non-arroyo areas of the upper bajada where this study was conducted have an essentially monospecific shrub cover of creosotebush and support a veriety of annuals and the small perennial grass Erioneuron pulchellum (fluff grass). Study plots were established in an area that is downslope from the LTER Upper Trailer and immediately downslope from the road running from the NMSU College Ranch headquarters SSE past the LTER Weather Station and exiting the College Ranch at the south boundary on the same powerline road that runs on along the north side of Mt. Summerford in the Dona Ana Mountains.

Maintenance: 

once per month for 3 months (March, July, September 1986)
