Abstract:

The North Desert Village (NDV) landscape experiment at the Arizona State University Polytechnic campus was designed to give a platform for CAP LTER researchers to study human–landscape interactions. Four residential landscape design and water-delivery types established in blocks of six households each (mini-neighborhoods) mirrored the four prevailing residential yardscape types found across the greater Phoenix metropolitan area: (1) Mesic: a mixture of exotic high water-use vegetation and shade trees with turf grass, (2) Oasis: a mixture of drip-watered, high and low water-use plants on granite substrate, and sprinkler-irrigated turf grass, (3) Xeric: individually watered, low water-use exotic and native plants on granite substrate, and (4) Native: native Sonoran desert plants on granite substrate without supplemental water. Six additional households are monitored in a control treatment area that did not receive landscaping treatment or supplemental water. Major research questions include: How do landscape design and irrigation methods affect net primary productivity and under-canopy microclimate, and soil nutrient pools and fluxes. In addition, the mini-neighborhoods at NDV were incorporated into CAP LTER biodiversity monitoring programs, facilitating insights into insect abundance and diversity, and bird activity in these experimental treatment areas. During summer 2005, the landscape and irrigation systems for each of the treatment areas were completed. During spring 2006, micrometeorological (micromet) stations were installed in the central common area of each treatment area. Data continually monitored included soil temperature, soil heat flux, and volumetric water content of soil at 30-cm depth. Air temperature at 2-m height and soil-surface temperature (recorded by an infrared thermometer at 2-m height) were also monitored regularly. Landscape irrigation water application volumes were recorded approximately monthly, and the electric meters of treatment-area dwellings were monitored for a period. These data allowed scientists working at NDV insight into research questions involving water conservation and urban heating, undercanopy layer microclimates, and water-use efficiency.

Column Description Type Units
treatment type of landscaping characteristic of that site
Enumeration:
  • mesic: a mixture of exotic high water-use vegetation and shade trees with turf grass
  • xeric: individually watered, low water-use exotic and native plants on granite substrate
  • control: mini-neighborhood where a landscaping treatment was not applied
  • native: native Sonoran desert plants on granite substrate and no supplemental water
  • oasis: a mixture of drip-watered, high and low water-use plants on granite substrate, and sprinkler-irrigated turf grass
sample sample location in the form of the first letter of the treatment type, habitat code, and replicate number
habitat general habitat from which the sample was collected
Enumeration:
  • canopy: sample collected beneath the canopy of a tree or shrub
  • open: sample collected from a location with an open canopy
  • turf (at oasis): sample collected from the turf covered area of the oasis treatment area

Description: This zipped file contains the programs that run the Campbell Scientific CR1000 data loggers that are continuously recording data about micrometeorological and subsurface conditions at the CAP LTER North Desert Village Experiment. Sensors and loggers are positioned in the common area of four mini-neighborhoods each refleting a unique landscaping treatment.
