ECOLOGICAL REGION
#21 COLUMBIAN PACIFIC.UTM— to —-?(The Columbian Pacific region stretches along the Pacific coast from Cape Mendocino in the South, northward to include the Straight of Juan de Fuca and end at northern tip ofVancouver Island, in the North. The region is home to abundant plant and wildlife, but also has one of the fastest growing human populations in North America. )

From the NatureServe website, a brief description of the BIOTOPE:
The finest level of the classification is the Biotope. The biotope is a specific area of a habitat that
includes recurring, persistent, and predictable biological associations. The biological associations can
include plants, attached sessile fauna and unattached but relatively non-motile fauna and bacterial
colonies. A biotope is environmentally uniform in structure, environment, and is defined by the dominant
biota. The primary characteristic of the biotope is the relationship between the physical habitat and a
strongly associated or fixed “high fidelity” plant and animal species. “Fixed” is defined as an individual
organism that cannot move beyond the frame of reference of the habitat boundary within one day.
Epibenthic,( on the surface of the ocean bottom) organisms like anemones, sponges, hydroids, and benthic infauna (buried in the bottom sediments) such as polychaetes would be considered part of a biotope complex.While much of the sedentary or fixed biota defines a particular biotope, other organisms demonstrate less
fidelity to any specific biotope. More motile or vagile organisms can be associated with multiple biotopes or
interact with the physical structure of the environment at any number of classification levels and spatial or
temporal scales. Larger animals, such as blue whales, may interact with elements defined in the
classification at a level of Formations, such as the shelf break or submarine canyon. Smaller animals
interact with Macrohabitats, Habitats or Biotopes. As the classification matures, the linkages of species and biological
associations to different classification units at different levels will become better known and documented.Detailed Description and Rationale
The biotope concept has been employed for several years in Europe and is defined as the “physical
habitat… and its community of animals and plants (Costello, 2003).” This refers to the dominant
biological inhabitant(s) of a specific habitat, whether the species are “diagnostic,” as in the terminology of
Cowardin (1979) and Dethier (1990), or if they are “commonly associated.” A species is considered to be
part of a biotope if it is conspicuous, dominant, and physically linked to the habitat. The concept and
nomenclature for the biotope follow the BioMar system (Costello, 2003; Connor, 1997), which has been
integrated into the EUNIS classification for European habitats (Davies and Moss 1999) and into this
classification, although some of the terminology has been changed here. |
