Title:

Ground cover data from line-point and canopy gap intercept transects at the Cross-Scale Interactions Study (CSIS) at Jornada Basin LTER, 2011-ongoing

Alternate Identifier:

DOI PLACE HOLDER

Abstract:

This dataset contains ground cover and canopy gap data collected along transects in a long-term experiment (2011-present) of cross-scale interactions (CSIs) at the Jornada Basin LTER site in southern New Mexico, U.S.A. Experimental treatments were initiated in 2013 at 15 experimental blocks, each with 4 treatment plots: plant-scale herbicide of mesquite shrubs, patch-scale connectivity modifiers (ConMods), herbicide + ConMods, control without manipulations. Plant cover was measured along three 25 meter transects in each plot using the line-point intercept (LPI) method. The data table contains cover type occurrences (species or cover type) and status (dead, seedling, etc.) every 25 centimeters along the transect. Canopy gap intercepts were measured along the same transects and the resulting data table contains gap start, end, and interval data. This study is ongoing.

Description:

Experimental design

The experimental design for the Cross-Scale Interactions study (CSIs) consists of 15 - 1 ha blocks spatially distributed across the study area selected to have similar total percentage vegetation cover within a block, but to vary in the proportion of perennial grass and mesquite cover among blocks. At each block location, four 15 x 25 meter experimental plots were identified with similar percentage grass and shrub cover. Within an experimental plot was a buffer area, an 8 x 8 meter treatment or control subplot (the "focal patch"), and 8 x 8 meter upwind and downwind subplots. Each experimental plot was arrayed perpendicular lengthwise to the dominant southwest to northeast wind direction, and was placed > 15 meters away from the other experimental plots to minimize between-plot treatment effects. Excluding the buffer zones, the distance between focal patches and subplots in different experimental plots ranges from > 20 to ~40 meters.

Each experimental plot within a block was randomly assigned to one of four connectivity treatments: (1) plant scale where all mesquite plants within and surrounding the focal patch were killed in place with herbicide to modify competitive interactions between woody plants and recovery of perennial grasses and other herbaceous plants with no direct effects on horizontal transport by wind and water, (2) patch scale where Connectivity Modifiers (ConMods, Okin et al. 2015) were located in bare soil interspaces between plants in the focal patch to reduce gap size and to modify transport of water, soil, nutrients, litter, and herbaceous seeds, (3) both patch- and plant-scale manipulations were conducted in each focal patch, and (4) no manipulations [controls]. Block and plot selection were completed in June 2012 followed by the characterization of initial vegetation cover in all plots in June 2013 when treatments were initiated.

Assignment of treatments to experimental plots (by block) is described in the attached files "csis_treatment_key.csv" and "Study413_CSIS_Plot_Treatments.pdf".

Line-point intercept and gap fraction measurements

In each plot (4 per block), two 25-meter transects were established in 2011. Plant cover was measured along the transects in each plot using the line-point intercept method (Herrick et al. 2017) in spring and fall each year thereafter. The resulting data table contains cover type occurrence (species or cover type) every 25 centimeters along the transect. In 2014 an additional transect was added to each plot and canopy gap intercept measurements were initiated. Canopy gap fraction was measured along the same transects and at the same times as LPI, also using a method desribed in Herrick et al. (2017).

Vegetation and other ground cover codes are described in the included file "CSIS_LPI_cover_codes.csv".

Abstract:

Dryland ecosystems occupy nearly half of the Earth's land surface and provide goods and services for more than 1 billion people. The goal of the Jornada Basin Long Term Ecological Research (LTER) program is to understand what factors determine the structure and function of drylands, and to develop general principles governing changes between grassland and shrubland ecosystems. This research is 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.
