Alternate Identifier:DOI PLACE HOLDER
Abstract:

This data was collected from 1984-1985 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 m2 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/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.

Sampling design

=======================================

This data was collected from 1984-1985 as part of the Jornada Basin LTER program.

This data was collected from 1984-1985 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 m2 quadrats. Annual plants were measured in the northeast 1 square meter of each quadrat by placing one square meter PVC pipe frame in the northeast cornor of each quadta. All individuals of each species that were present in the frame were counted and measured. A mean diameter, height, and the total number of individuals/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.

Additional Files

An additional metadata file - jgrashop.dsd.txt - from the earlier Jornada information management system is included and may contain useful metadata.

A list of species codes - JornadaGrasshopperDatasetCodes.txt - is included and should be used alongside the dataset to identify the plant species attribute codes.
