Construction Status for this Site
Overview Site history & management
Land use at Jornada has contrasting livestock grazing histories (including ungrazed lands), dating back to 1902, which are representative of the pervasive land use in desert-southwest wildlands. Historical accounts of the region report significant changes in vegetation starting in the late 1800s coincident with the expansion of livestock grazing. By 1912, sufficiently dramatic changes lead area scientists and private landowners to convince the U.S. government to set aside Public Domain Lands for the Jornada Range Reserve for the purpose of scientific investigation on shrub invasion and subsequent loss of forage grasses. Much of this early research focused on quantifying utilization levels for forage species, developing livestock production strategies to deal with drought, and developing methods for shrub control and grass recovery. Exclosures were constructed and long-term plots were established throughout the range to monitor the continued expansion of shrubs across the landscape. Over the decades, numerous trials of various remediation approaches were implemented, from manual and mechanical shrub removal to herbicide application to construction of terraces or other means of redirecting surface flow of runoff.

Data Collection Types
Airborne Remote Sensing Surveys
Remote sensing surveys of this field site collect lidar, spectrometer and high-resolution RGB camera data.
The flux/meteorological tower at this site is 26’ with 4 measurement levels. The tower top extends above the vegetation canopy to allow sensors mounted at the top and along the tower to capture the full profile of atmospheric conditions from the top of the vegetation canopy to the ground. The tower collects physical and chemical properties of atmosphere-related processes, such as humidity, wind, and net ecosystem gas exchange. Precipitation data are collected by a tipping bucket at the top of the tower and a series of throughfalls located in the soil array.
This site has one phenocam on the top of the flux tower and one near the bottom of the tower.
Soil Sensor Measurements
This site has five soil plots placed in an array within the airshed of the flux tower. The following measurements may be collected at the soil surface in each soil plot:
Photosynthetically Active Radiation (PAR) at soil surface
Soil heat flux
The following measurements are collected at multiple depths in each soil plot:
