Ecological observation point

Ecological observation point From 1986 to 2000, a major ecological inventory program was carried out in the forests of southern Quebec in order to describe the diversity of forest ecosystems. In total, 28,425 ecological observation points (POE) were established on a territory covering 760,000 km2, located between 45° and 53° N latitude and 57° and 80° W longitude. The POE is a circular sampling unit that covers an area of 400 m². It collects data on the characteristics of forest stand (composition, structure), soil (texture, deposit, drainage), and topography, as well as location information. The coverage of each plant species in the plot is estimated visually. A detailed description of a soil profile is available in approximately 35% of POEs. The ecological classification elements of POEs (groups of indicator species, forest types, potential vegetation, ecological types, etc.) are determined using computerized identification keys using data on vegetation and the physical environment. The criteria used for this ecological classification are those presented in the guides for the recognition of ecological types. The levels of the ecological classification system of the territory are also determined for each POE.**This third party metadata element was translated using an automated translation tool (Amazon Translate).** 2025-05-01 Government and Municipalities of Québec inventaires.forestiers@mrnf.gouv.qc.ca Form DescriptorsNature and EnvironmentScience and Technology Ecological observation pointGPKG https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Points_observation_ecologique/Poe_prov_gpkg.zip Open forestHTML https://www.foretouverte.gouv.qc.ca/?context=_ecologie&zoom=9¢er=-72.50741,47.44859&invisiblelayers=*&visiblelayers=8a01f03f54fd7fff86bdd1ba1d79f341,1da64ddfeaf23710b8a9ad95133fb5d8 Open forestHTML https://www.foretouverte.gouv.qc.ca/?context=_telechargement&zoom=6¢er=-67.99891,48.9935&invisiblelayers=*&visiblelayers=634387214b14c87b4f78d72d2717829f,1da64ddfeaf23710b8a9ad95133fb5d8 Original metadata (https://www.donneesquebec.ca)HTML https://www.donneesquebec.ca/recherche/fr/dataset/7396a043-ee84-4068-9665-a22b509d8038 READ MEPDF https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Points_observation_ecologique/Documentation/LISEZ-MOI_POE.pdf The ecological point of view: technical standardsPDF https://mffp.gouv.qc.ca/documents/forets/inventaire/le-point-observation-ecologique-normes-tech-34.pdf Carrying out the samplingPDF https://mffp.gouv.qc.ca/documents/forets/inventaire/echantillonnage_POE.pdf Data downloadPDF https://mffp.gouv.qc.ca/documents/forets/inventaire/Telechargement_rapide.pdf Fact sheet of attributes and their areas of valueXLS https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Points_observation_ecologique/Documentation/DICTIONNAIRE_POE.xlsx Ecological observation pointother https://diffusion.mffp.gouv.qc.ca/Diffusion/DonneeGratuite/Foret/DONNEES_FOR_ECO_SUD/Points_observation_ecologique/Poe_prov_mdb.zip
