Data collected here help scientists understand the functions of desert ecosystems; deserts are uniquely sensitive to human disturbances. SRER is located in NEON\u0027s Desert Southwest Domain (D14). D14 has one other terrestrial field site and one aquatic field site. SRER is not colocated with an aquatic site.","citation":null,"relatedIdentifiers":null,"status":{"label":"Operational","uri":"http:\/\/vocabs.lter-europe.net\/elter_cl\/10772"},"yearEstablished":2015,"yearClosed":null,"relatedSites":null,"siteName":"Santa Rita Experimental Range NEON","shortName":"SRER","siteType":"Platform","protectionLevel":null,"landUse":null,"images":[{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-06\/48790215963_c25b285352_b.jpg","alt":"ecoforecasting Workshop 2019 at SRER, photo by Abe Karam"},{"url":"https:\/\/deims.org\/sites\/default\/files\/2020-06\/49803443151_46fc713b9c_b.jpg","alt":"Monsoon at SRER.

The range itself consists of some isolated foothills but is mostly comprised of gently sloped alluvial fans cut by canyons and arroyos. The geology of SRER is characterized by undivided sand and gravels.","hydrology":"Arroyos and gullies are common within the experimental range, representing the alluvial fan dominated area. Runoff flows to the west and northwest into the Santa Cruz River.","soils":"The soils found at SRER are those typical of desert regions - they are mostly composed of alluvial deposits from the Santa Rita Mountains, with alluvial caps covering approximately 95% of the region. The soil subgroup Typic Torrifluvents, within Entisols, are commonly found in NEON plots at SRER. Higher-elevation soils have higher organic content, less salt, and lower temperature than soils at lower elevations.","vegetation":"The dominant vegetation found in an area is highly dependent on elevation. For example, densities of velvet mesquite (Prosopis velutina) and cholla cactus (Cylindropuntia spp.) are greatest at elevations between 975 - 1100 m (3200 - 3600 ft.), but creosote bush (Larrea tridentata) dominates at elevations lower than 975 m (3200 ft.). Vegetation at the site is dominated by drought-resistant, thorny species. This includes a mix of short trees, shrubs, cacti and other succulents, perennial grasses, and annual forbs."},"geographic":{"boundaries":"POLYGON ((-110.807025444 31.875114991, -110.806977857 31.861805246, -110.806845531 31.847315716, -110.7899196 31.847252802, -110.781423848 31.847193378, -110.781431309 31.839966763, -110.789958166 31.83999917, -110.798807396 31.840022494, -110.798850477 31.818180223, -110.79896047 31.818162353, -110.798959647 31.804060875, -110.798963361 31.789535336, -110.807131742 31.789566014, -110.815622282 31.789605657, -110.815652484 31.782369979, -110.824128475 31.782427077, -110.824093732 31.774974767, -110.841058679 31.775033156, -110.84108025 31.768013971, -110.836856095 31.767990587, -110.836845439 31.760709712, -110.84110234 31.760688026, -110.841081003 31.756952833, -110.849587787 31.756954138, -110.849550984 31.760734372, -110.855645797 31.760795557, -110.855658426 31.7703049, -110.872648803 31.770232799, -110.872719423 31.755770378, -110.875689498 31.75577331, -110.889654961 31.755732038, -110.889644367 31.759376978, -110.893903108 31.759416684, -110.893956109 31.770234275, -110.906561699 31.770226101, -110.92402927 31.770129451, -110.92394472 31.784727202, -110.923816613 31.799261738, -110.940744175 31.799297808, -110.959998511 31.799280503, -110.960306453 31.812561114, -110.977271819 31.812466031, -110.977147425 31.820179883, -110.974058266 31.826530824, -110.966727653 31.841180927, -110.960488642 31.853800962, -110.960557424 31.84120623, -110.943856161 31.841515727, -110.926681503 31.84182276, -110.926769604 31.856140765, -110.926991749 31.870603166, -110.927152104 31.875069144, -110.927256733 31.884876098, -110.927230561 31.899248072, -110.927242133 31.913944824, -110.910265579 31.913852772, -110.893038861 31.913749219, -110.876678681 31.913770482, -110.875795505 31.9137606, -110.875595862 31.913760405, -110.858914446 31.913752, -110.858910853 31.919571134, -110.84060473 31.919549487, -110.823613955 31.919499969, -110.806576838 31.919493218, -110.789513912 31.919502184, -110.789615832 31.905365018, -110.790060069 31.905347708, -110.789944204 31.890731987, -110.806963085 31.890758971, -110.80703109 31.876369053, -110.807049563 31.875115028, -110.807025444 31.875114991))","coordinates":"POINT (-110.83549 31.91068)","country":["United States of America"],"elevation":{"avg":983,"min":897,"max":1461,"unit":"msl"},"size":{"value":21490,"unit":"ha"},"relatedLocations":null},"focusDesignScale":{"experiments":{"design":"mainly experimentation","scale":"beyond catchment scale"},"observations":{"design":"mainly observation","scale":"beyond catchment"},"observedProperties":[{"label":"DNA sequence","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/21400"},{"label":"above ground biomass","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22025"},{"label":"air temperature","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22035"},{"label":"atmospheric parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20937"},{"label":"biological parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20940"},{"label":"chemical parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10333"},{"label":"ecosystem parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20939"},{"label":"genetic parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20942"},{"label":"heat flux","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22130"},{"label":"land cover","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22142"},{"label":"landscape parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20943"},{"label":"latent heat","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22154"},{"label":"leaf area index","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22157"},{"label":"ozone concentration","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22178"},{"label":"plant diversity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22191"},{"label":"precipitation intensity","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/22204"},{"label":"soil carbon dioxyde flux","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/21939"},{"label":"soil moisture content","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10039"},{"label":"soil parameter","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/20944"},{"label":"species abundance","uri":"http:\/\/vocabs.lter-europe.net\/EnvThes\/10018"}]},"infrastructure":{"accessibleAllYear":true,"accessType":null,"allPartsAccessible":null,"maintenanceInterval":null,"permanentPowerSupply":true,"operation":{"permanent":true,"notes":null,"siteVisitInterval":null},"notes":null,"collection":null,"data":{"policy":{"url":null,"rights":null,"notes":null}}},"relatedResources":null,"projectRelated":{"lter":{"lterSiteClassification":null}}}}
