Abstract:

This dataset contains archived overhead photos collected from microplots in a long-term experiment (2013-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, and control without manipulations. Repeat, overhead (downward-looking) photographs of ten "microplots" in each plot were taken for estimation of litter, soil, and vegetation cover in the experimental treatment and control plots over time. Photographs have been cropped, and in some cases rotated, to provide standardized areas for this analysis. The photographs are archived by year in Zip files. This study is ongoing and new photos will be added annually. Cover estimates derived from these photos are in EDI dataset knb-lter-jrn.210413005.

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 15m x 25m plots were identified with similar percentage grass and shrub cover with a focal patch in the center. Plots were arrayed perpendicular lengthwise to the dominant southwest to northeast wind direction, and were >15 m apart to minimize between-plot treatment effects.

Each 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 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 file "csis_treatment_key.csv".

Overhead photo collection

In each plot (4 per block), repeat overhead photos of ten randomly selected microplots were photographed annually. Photos were taken from directly above the microplot (overhead, or downward-looking orientation) from a height of approximately 85cm above ground level using a 12.1 megapixel digital camera, resulting in image dimensions of 4,000 x 3,000 pixels. In ConMod-only and ConMod + Herbicide treatments, photos were centered over the center post of the ConMod structure, and in Control and Herbicide-only plots photos were centered over a marker nail affixed to the soil surface. Annual photos were taken in winter (Jan-Feb) from 2013-2016 to try to better distinguish perennial grass from annual plant biomass. In 2017 the method changed and photos were taken near peak biomass during the growing season (July-Sept) in order to better capture and identify living biomass. Images were archived for later analysis of plant growth and litter accumulation within the microplots.

Before cover analysis, photos were standardized by cropping, and in some cases by rotating, for use in USDA SamplePoint software (Booth et al. 2006, Peters et al. 2020). Photos in this dataset are the ones used in these later analyses in the study and are archived by year in zip archives. A directory to the photos is provided in the file "jrn413004_photo_archive_dir.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.

Funding:

The Jornada LTER program has been continuously funded by the U.S. National Science Foundation since 1982 (Current NSF award: DEB-2025166)
