Title:Soil disturbance cover data on 1m x 1m plots from the long-term Small Mammal Exclusion Study (SMES) at Jornada Basin LTER, 1995-2015
Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data package contains soil disturbance data from plots with various levels of herbivore exclusion on the Jornada Experimental Range (JER) and Chihuahuan Desert Rangeland Research Center (CDRRC) lands. Study sites were established in 1995; one in black grama grassland and the other in creosotebush shrubland to compare the impact of herbivores on ecosystem processes between these vegetation types. Parallel studies were established at the Sevilleta LTER site (New Mexico, USA) and Mapimi Biosphere Reserve (Durango, Mexico). Each study site is 1 km by 0.5 km in area. Four replicate experimental blocks were randomly located at each study site to measure vegetation responses using exclusion treatments including a) all mammalian herbivores, including cattle, lagomorphs, and rodents, b) lagomorphs and cattle only, c) cattle only, and d) control accessible to all herbivores. Thirty-six sampling points were positioned at 5.8-meter intervals on a systematically located 6 by 6 point grid within each plot. A permanent one-meter by one-meter vegetation measurement quadrat is located at each of the 36 points. Each year in spring and fall from 1995-2005, various forms of disturbances (human, rabbit, cow, antelope, rodent, etc) were measured by depth . After 2005, sampling frequency changed to every 5 years. This study is ongoing.

Description:

Each study site is 1 km by 0.5 km in area. Four replicate experimental blocks were randomly located at each study site depending on whether the site was grazed. The blocks are all oriented on a site in an X/Y coordinate system, with the access road to each site forming the X axis. The compass orientation at the Jornada grassland site is to the north, and Jornada creosotebush site is oriented to the south. Treatments within each block include one unfenced control plot (Treatment: C; control); one plot fenced with barbed wire, hardware cloth, and poultry wire to exclude rodents, rabbits, and cattle (Treatment: R; rodent); one plot fenced only with barbed and poultry wire to exclude cattle and rabbits (Treatment: L; lagomorph); and one plot fenced with barbed wire to exclude cattle (Treatment B; bovine). Cattle exclosure plots with barbed wire occur only at the black grama grassland site where cattle were present, for a total of 4 treatment plots at each of the four grassland site blocks. There are only 3 treatment plots at each of the creosotebush site blocks. The treatments were randomly assigned to each of the three or four possible plots in each block independently, and their arrangements differ from block to block. Each of the plots in a replicate block is separated by 20 meters. Each plot measures 36 meters by 36 meters. Thirty-six sampling points are positioned at 5.8-meter intervals on a systematically located 6 by 6 point grid within each plot. A permanent one-meter by one-meter vegetation measurement quadrat is located at each of the 36 points.

All cover values are measured using the vegetation measurement frame, which is 1 meter by 1 meter and partitioned into a grid of 100 10 cm by 10 cm squares. Percent cover of disturbances is estimated in minimum increments of 0.1 within each 10 cm square. The maximum vertical extent of each disturbance is measured as far as is visible (excluding long burrows for example) in centimeters. Total soil disturbance cover is then determined as the sum of disturbance areas in all 36 squares within the quadrat and converted to total percent cover (%). Detailed descriptions of measurement techniques are described in the protocol document attached to this package ("SMESvegquadprotocol.pdf").

These measurements were taken twice a year in the spring and fall from 1995-2005. After 2005, sampling frequency changed to once every 5 years in the fall. This study is ongoing.
