The experiment was implemented as a randomized complete block with 3 levels of grazing (summer, winter, and control) and 2 levels of shrub treatment (shrub removal and control) in each of 3 replicate blocks. The 18 experimental units are 0.5 ha (70 x 70 m) exclosures constructed in a mesquite-invaded black grama grassland in the southwest portion of the Jornada Experimental Range in Dona Ana County, New Mexico, USA. Vegetation sampling was conducted with the line-point intercept method. Initial pre-treatment sampling occurred in 1996. Grazing treatments removed 65-80% of aboveground perennial grass biomass over 24-36 hour periods in each of four years from summer 1996 to winter 2000; shrub removal occurred during this time as well. No livestock grazing or shrub removal have occurred since 2000. Post-treatment sampling occurred in 2002, 2009, and 2016. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: Website Pointer to html file.</p> <p>File Name: Web Page, url: <a href=\"https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210461001\">https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210461001</a> </p><p>Webpage with information and links to data files for download</p></li></ul><p></p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210461001", "mediaType": "text/html", "title": "https://portal.edirepository.org/nis/mapbrowse?scope=knb-lter-jrn&identifier=210461001"}], "identifier": "10.6073/pasta/cc0b40f7a34e52b612f384ff0f246e06", "keyword": ["ARS", "Jornada Basin LTER", "NP216", "NSF > LTER=Long-Term Ecological Research", "Pasture 9", "Plant-Animal Interactions", "Populations", "Stressor2", "Study 461", "black grama", "data.gov", "desertification", "disturbance", "early warning", "grasses", "grazing", "herbivory", "herbs", "honey mesquite", "long-term experiment", "patch size", "plant", "regime shift", "resilence", "sandy ecological site", "shrub encroachment", "shrub invasion", "shrubs", "state-transition model", "vascular plants"], "license": "https://creativecommons.org/licenses/by/4.0/", "modified": "2025-11-22", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "spatial": "{\"type\": \"Point\", \"coordinates\": [-106.833181, 32.589161]}", "temporal": "1996-01-24/2016-10-26", "title": "Perennial grass recovery following livestock overgazing and shrub removal: an experiment at the Jornada Experimental Range (Jornada Basin LTER), 1996-2016"}
