Status Attribute label Enumerant label ▾ Concept definition Code Ref type Reference Supplemental references
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BAMBOO_TREED_TRACT Comprised of woody tall <GRASS> <SHRUB>/woods, having evergreen <VEGETATION> and a moist-wet, hot-mild climate; bamboo treed tract. Dominant taxa include Bambusa (Asia) and Oxylenanthera (Africa). 1 IR [GEF1, Olson Ecosystem Type BAMBOO: 88 (bamboo wood/scrub)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BARE_COAST_DUNE Comprised of moving/reversible <SAND_DUNE>s, having sparse <VEGETATION> and a hot-cold, dry climate; bare coast dune. Dominant taxa include Cakile, Corispermum, Lathyrus, and Croton. This Olson ecosystem type occurs where the <WIND> limits <VEGETATION> to a small fraction of the land <<AREA>> (for example: less than ten percent over an <<AREA>> of more than one square kilometre). 2 IR [GEF1, Olson Ecosystem Type BARECOASTDUN: 83 (bare coast dune)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BARE_DESERT Comprised of ephemeral/sparse xerophytes, having low cover <VEGETATION> and an extreme drought hot-cold climate; bare desert. Dominant taxa include Salsola, Ambrosia, Cordylanthus, Lactuca, and Capparis. 3 IR [GEF1, Olson Ecosystem Type BAREDESERT: 8 (bare desert)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BARREN_TUNDRA Comprised of dwarf herb, <SHRUB>, moss, lichen, having variable <VEGETATION> and a cold permafrost climate; barren tundra. Dominant taxa include Oxyria, Alopecuris, Carex, and Eriophorum. 4 IR [GEF1, Olson Ecosystem Type TUNDRABARREN: 53 (tundra barren arctic)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BEACH_FOREDUNE_SHORELINE Comprised of low linear <SAND_DUNE>s, having pioneer <VEGETATION> and a wind-swept, storm-swept climate; beach foredune shoreline. Dominant taxa include Uniola, Elymus (Leymus), Ammophila, Andropogon, and Prunus. This Olson ecosystem type is a subtype of <<<COAST_HINTERLAND>>> that averages 0 to 3 metres above sea level in a <REGION> with an <<AREA>> of one square kilometre. Beach foredune shoreline can be more specifically separated into <<<SPARSE_DUNE_BUILDER>>>, <<<BARE_COAST_DUNE>>>, <<<RESIDUAL_DUNES_BEACH>>>, <<<COMPOUND_COAST>>>, and/or <<<ROCK_CLIFF_SLOPE>>>. 5 IR [GEF1, Olson Ecosystem Type BEACHFORDUNE: 81 (beach fore-dune)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON BROADLEAF_CROP_LAND Comprised of leafy rowcrops with/without <GRASS> and comprised of woody <VEGETATION>, having annual tops <VEGETATION> and a hot-cold climate; broadleaf crop land. Dominant taxa include Arachis (peanut), Solanum, Vitis (grape), and Humulus (hop). 6 IR [GEF1, Olson Ecosystem Type BROADLEAFCROP: 92 (broadleaf crops)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COAST_HINTERLAND Comprised of <BEACH>/<SAND_DUNE>/<ROCK>/slope, having variable <VEGETATION> and a marine climate; coast hinterland. Dominant taxa include Cakile and Lathyrus. This Olson ecosystem type has subtype <<<BEACH_FOREDUNE_SHORELINE>>>. 11 IR [GEF1, Olson Ecosystem Type COASTHINTLND: 80 (coast hinterland)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COAST_WETLAND_NE Comprised of mixed wet/dry <COAST> such that the principal land part, whether mainland or <ISLAND>, is in the north-east quadrant of the <REGION> being characterized, having variable <VEGETATION> and a hot-cold, windy climate; coast wetland-north-east. Dominant taxa include Spartina, Elymus, Ammophila, and Uniola. 7 IR [GEF1, Olson Ecosystem Type CSTWETLND-NE: 66 (coast wetland-NE)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COAST_WETLAND_NW Comprised of mixed wet/dry <COAST> such that the principal land part, whether mainland or <ISLAND>, is in the north-west quadrant of the <REGION> being characterized, having variable <VEGETATION> and a hot-cold, windy climate; coast wetland-north-west. Dominant taxa include Spartina, Elymus, Ammophila, and Uniola. 8 IR [GEF1, Olson Ecosystem Type CSTWETLND-NW: 65 (coast wetland-NW)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COAST_WETLAND_SE Comprised of mixed wet/dry <COAST> such that the principal land part, whether mainland or <ISLAND>, is in the south-east quadrant of the <REGION> being characterized, having variable <VEGETATION> and a hot-cold, windy climate; coast wetland-south-east. Dominant taxa include Spartina, Elymus, Ammophila, and Uniola. 9 IR [GEF1, Olson Ecosystem Type CSTWETLND-SE: 67 (coast wetland-SE)]  
Group membership:

In addition to the status and date information for each entry, a colour coding scheme highlights the database holding to which an entry belongs. The following highlight colours are used:

  • white - the entry is in the standard
  • yellow - the entry has been added to the register
  • pink - the entry has been submitted for inclusion in the register, but it is not approved
  • cyan - a deprecated entry that was originally either in the standard or was added to the register, but has since been deprecated

The following icons are used to identify items that have figures, modifications and/or clarification notes:

  • F n - has Figures and, if more than one figure, n figures
  • M - has Modifications
  • C - has Clarifications
