Description: The Primary Land and Vegetation Inventory (PLVI) is a photo-based digital inventory developed to identify the type, extent and conditions of vegetation in the forested and parkland areas of the province of Alberta. This includes portions of both the Green and White areas of the province. It will include areas of the province extending north from the extent of the Grassland Vegetation Inventory (GVI) and will include areas where the detail and expense of Alberta Vegetation Inventory (AVI) are not warranted, or time and resources are limiting constraints. Ecological site phase (ecosite phase) is the main level of classification used in PLVI. A polygon may be attributed with up to 3 ecological site phases, depending on complexity and extent. PLVI captures range site attributes only within the Central Parkland Natural Subregion. The most up to date ecological site phases can be found in the Plant Community Guides. Guides are broken into individual Natural Subregions. See the Cross Reference Section for additional information.
