Ecological land classification

From Wikipedia, the free encyclopedia
Jump to: navigation, search


Ecological land classification is defined as being a cartographical delineation of distinct ecological areas, identified by their geology, topography, soils, vegetation, climate conditions, living species, habitats, water resources, as well as anthropic factors (corroborated by ref).[1] These factors control and influence biotic composition and ecological processes.

Types[edit]

Many different lists and ecological land classification schemes have been developed.[2][3]

In Canada ecological land classification schemes are commonly used. Provincial authorities have adopted methods to classify ecosystems within various ecoregions of the province. Ontario is one such province that uses an extensive method to define ecological units. Improvements in hand held technology have allowed for more efficient collection of vegetation and physiological data in the field, such as with the ELC eTool.

Hierarchy of classification levels in ecology compared to other fields[edit]

This classification table shows the parallel classification terms in similar spatial scales used in the study of the biotic and abiotic components of ecosystems and the Earth.

From largest at top to the smallest at bottom the classification levels are:
CLASSIFICATION LEVELS IN ECOLOGY COMPARED TO OTHER FIELDS
Biotic Abiotic
ECOLOGY BIOGEOGRAPHY ZOOGEOGRAPHY PHYTOGEOGRAPHY PHYSIOGRAPHY GEOLOGY PEDOLOGY
ecosphere biosphere zoosphere phytosphere physiosphere geosphere pedosphere
ecozone biome zoozone (zoogeographic region) [4][5] floristic kingdom
ecoprovince bioprovince zooprovince[6] floristic region geoprovince
ecoregion bioregion zooregion floristic province physioregion georegion pedoregion
ecodistrict biodistrict floristic sector
ecosection biosection floristic district
ecosite biosite
ecotope (ecosystem sensu stricto?)[citation needed] biotope zootope phytotope physiotope geotope pedotope
ecoelement bioelement geoelement
