Alternate Identifier:DOI PLACE HOLDER
Abstract:

This dataset contains annual herbaceous plant data collected in association with grasshopper surveys during 1984 and 1985 as part of the Jornada Basin LTER program. Annual herbaceous plant data was collected from Jornada grasshopper plots on the east bajada of the Dona Ana Mts. Three plots were situated on the bajada parallel to and 200 m south of the LTER-I transect. Two additional sets of three plots were located 5 km and 10 km south of the LTER transect. Each plot is composed of two 50 m belt transects, each divided into ten 5-meter-squared quadrats. Annual plants were measured in the northeast 1 square meter of each quadrat. All individuals of each species were counted and measured. A mean diameter, height, and the total number of individuals per 1-square-meter quadrat were recorded. Measurements were taken in May, July, and September of 1984, and in May and September of 1985. This dataset consists of the date of collection, plot number, transect number, quadrat number, plant species code, mean plant diameter, and mean plant height. This dataset is complete.

Description:

Locations and data collection

Three plots were situated on the bajada of the Dona Ana mountains, parallel to and 200 m south of the LTER-I transect. Two additional sets of three plots were located 5 km and 10 km south of the LTER transect. Each plot is composed of two 50 meter belt transects, each divided into ten 5-square-meter quadrats. Annual plants were measured in the northeast one square meter of each quadrat once in May, July and September in 1984, and again in May and September of 1985. All individuals of each species were counted and measured. A mean diameter, height, and the total number of individuals per square-meter quadrat were recorded.

The protocol for observations was to place a one square meter PVC pipe frame in the northeast corner of each quadrat (see abstract), then record all herbaceous plant species present in the frame, record mean diameter (cm), height (cm), and total number of individuals for each species.

Additional files

Two additional files are included with this dataset. The first - jgrashop.lst.txt - describes the codes for grasshopper species and vegetation observed in the data file. The other - jveg.dsd.txt - is a metadata text file from the earlier Jornada information management system and may contain useful metadata.

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.

Funding:

At the time of this study, JRN LTER was funded by the National Science Foundation under award DEB 8114466 (LTER-I).
