It is in the Caribou-Poker Creeks Research Watershed and contained within the Bonanza Creek LTER research area. The land at the Bonanza Creek LTER site is managed by the University of Alaska and has been set aside for scientific study. Parts of the NEON site also overlap land managed by the Alaska Department of Natural Resources. The 49.6 km2 (12,300 acre) site features a mix of hardwood forest, shrubland, wetlands, and scattered permafrost. The Caribou-Poker Creeks Research Watershed spans an elevation of 200 - 773 m (650 - 2500 ft.), with valleys and steep mountains within the watershed. BONA is one of four NEON sites (three terrestrial and one aquatic) in the Alaskan Taiga Domain (D19), which comprises Alaska\u2019s interior and the Alaska Peninsula. It is colocated with the aquatic site CARI.

Quartzite is also found here, and aeolian silts derived from the Tanana Flats overlay the area.","hydrology":"The Caribou-Poker Creeks Research Watershed is characterized as a typical upland headwater stream basin in subarctic Alaska. During peak melt times, the discharge in Caribou Creek can reach upwards of 1000 liters per second. Key hydro-biological research topics conducted in CPCRW include how permafrost thaws and how wildfires affect fresh water stream ecology.","soils":"Soils within BONA are typically silty alluvium and colluvium materials, with layers of permafrost on the surface. Gilmore silt loam, Typic Cryochrepts and Histic Pergelic Cryaquepts are some of the major soil types within the site. The soils within BONA are affected by the cycle of ice thawing and freezing, resulting in cryoturbation (). ","vegetation":"The BONA area contains areas of permafrost, hardwood forest, wetlands, and shrublands. Moss covers patches of permafrost throughout the Caribou-Poker Creeks Research Watershed area. The hydrology and drainage of the area influences dominant vegetation types, with areas of poor drainage dominated by moss, sedge, and shrub species. Evergreen forest constitutes the majority of land area within the site. Black spruce (Picea mariana), lingonberry (Vaccinium vitis-idaea), and bog Labrador tea (Ledum groenlandicum) are some dominant species."},"geographic":{"boundaries":"POLYGON ((-147.43979028 65.180762317, -147.43979028 65.14501832, -147.465725841 65.145136171, -147.466286609 65.140716372, -147.492923131 65.141011048, -147.493343707 65.137356832, -147.508204082 65.137180003, -147.50806389 65.180644623, -147.43979028 65.180762317))","coordinates":"POINT (-147.50258 65.15401)","country":["United States of America"],"elevation":{"avg":230,"min":212,"max":728,"unit":"msl"},"size":{"value":3570,"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}}}}
