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 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 DECID_BROADLEAF_FOREST Comprised of medium/tall <FOREST>, having cold-deciduous <VEGETATION> and a mild-hot climate; deciduous broadleaf forest. Dominant taxa include Quercus, Carya, Liriodendron, Magnolia, Acer, and Juglans with <<<DECID_BROADLEAF_TREED_TRACT>>>. 32 IR [GEF1, Olson Ecosystem Type BROADLFOREST: 26 (broadleaf forest)]  
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 COLD_GRASSLAND Comprised of browsed meadow/steppe, having annual top <VEGETATION> and a cold, windy, dry-wet climate; cold grassland. Dominant taxa include Calamogrostis, Elymus, Eriophorum, other herbs, and Azorella. 12 IR [GEF1, Olson Ecosystem Type COLDGRASSLND: 42 (cold grassland)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COLD_IRRIGATED_CROP-
_LAND		 Comprised of tilled/hay pastured fields, having some irrigated crop <VEGETATION> and a snowy, long winter climate; cold irrigated crop land. Dominant taxa include Solanum tuberosa (potato), and Brassica (cabbage). 13 IR [GEF1, Olson Ecosystem Type COLDIRRIGATD: 39 (cold irrigated crops)]  
STD
2005/06/07		 ECOSYSTEM_TYPE_OLSON COMPOUND_COAST Comprised of a mixture of <<<HEATH_SCRUB>>>, <<<MANGROVE_FOREST_SCRUB>>>, <<<WATER_ISLAND_FRINGE>>>, <<<LAND_WATER_SHORE>>>, <<<LAND_WATER_RIVER>>> <<<CROP_LAND_WATER_MIXED>>>, <<<S_HMISPH_CONIFER>>>, <<<COAST_HINTERLAND>>>, and/or the other subtypes of <<<COAST_HINTERLAND>>>, having varied cover <VEGETATION> and a varied climate; compound coast. 14 IR [GEF1, Olson Ecosystem Type COMPOUNDCST: 85 (compound coast)]  
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
