Abstract:

This data package contains weights of windblown dust collected by BSNE collectors at long-term vegetation-removal plots that are part of the Jornada Basin LTER Nutrient and Ecosystem impacts of Aeolian Transport (NEAT) study located at the Jornada Experimental Range. The dataset can be used to estimate horizontal dust flux in vegetation removal treatment plots (different percentage vegetation removed) and contiguous downwind plots. Year 2008 was the initial collection and collections in subsequent years occur before and after the windy season. The experiment was designed to test the effects of increases in wind erosion on soil and vegetation properties on the sand sheet geomorphic unit for different levels of herbaceous cover. In order to increase wind erosion rates, vegetation was removed each spring to increase bare surface area and stimulate erosion (the less vegetation present the greater the wind erosion). The experimental design includes three blocks located in one pasture, each with four treatment plots that are maintained at one of four levels of herbaceous vegetation and small shrubs removed (25, 50, 75, 100%) and a control. Treatment plots are 25x50m with 25m buffers between. The vegetation removal includes grasses and small shrubs (like Gutierrezia sarothrae and Zinnia grandiflora), but not mesquite or yucca or any of the larger shrubs. Also, contiguous downwind plots are monitored for soil and vegetation properties, but no removal treatments are performed in these areas. A control treatment where no vegetation was removed that was not downwind of any treatment is also included. This study is ongoing and is updated twice per year - before and after the spring windy season.

Description:

Basic Experimental Design

The experiment was designed to test the effects of increasing wind erosion on soil and vegetation properties at the Jornada. In order to increase wind erosion rates, vegetation was removed to increase bare surface area and stimulate erosion (the less vegetation present the greater the wind erosion). The basic experimental design includes three treatment blocks. Each block has four treatment plots with different levels of vegetation removed (25-100%) and a control treatment. Treatment plots are 25x50 meters with 25 meter buffers between. The vegetation removal includes grasses and small shrubs (like Gutierrezia sarothrae and Zinnia grandiflora), but not mesquite, yucca, or any of the larger shrubs. Also, adjacent downwind plots are included in the design. These plots are strictly for monitoring of soil and vegetation properties, so no maintenance is required on these areas.

Each treatment area (upwind) and adjacent downwind area has 6 BSNE stands, each with 6 or 4 dust collectors per vertical stand. There are two exceptions: Block 1, Treatment C has 3 downwind stands; Block 2, Treatment 3 has 4 downwind BSNE stands. On the Treatment 4 Upwind plots (the area with the most vegetation removal) these stands are 3m tall with 6 traps at heights 15, 30, 60, 90, 160, 250 cm respectively. All the other stands, including Treatment 4 Downwind, the dust collectors are 1 meter tall. The heights on these are 15, 30, 60, 120 cm. Heights are based on distance from ground to bottom of BSNE opening when collector is pointing 250° from true North (the prevailing wind direction).

A schematic of the plots is provided in "NEAT_BSNE_map.tif". Please note that the number, arrangement, and/or height of BSNE stands and collectors in NEAT plots has changed somewhat over time. Most of these changes are evident in the data or metadata, and complete historical details are available upon request from the JRN LTER data manager.

BSNE sampling and maintenance

Except for 2008 when it was an annual collection, BSNEs are collected twice a year, typically February (before windy season) and June (after windy season). As part of the biannual collection, the trap heights need to be measured and adjusted accordingly, along with any other maintenance that needs to be done (such as rewiring the traps, rebalancing the 3 meter stands, veg clipping, etc.). Vegetation is clipped as needed to allow BSNEs to freely rotate 360º. The dust from each trap gets placed in a 6x4 inch, 4-mil Ziploc-style bag and appropriately labeled and dated.

The air dry weight in grams of the dust sample in each collector is calculated from the mass of the sample and the bag minus the average mass of all bags used during the collection ( (Bag + Sample) - Avg_Bag_Wt ).

The general protocol and guidelines for BSNE data collection are described in detail in the attached "BSNE-protocol.pdf" document. This document is not specific to the NEAT study.

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.

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