Title: Derived Ecosite Phase
Dataset Publication Date: 2017-07-18
Abstract: The Derived Ecosite Phase (DEP) is a digital and spatial representation of ecological sites and phases in those areas of Alberta where both Alberta Vegetation Inventory (AVI) and LiDAR are available. The AVI is an imagery-based digital inventory developed to identify the type, extent and conditions of vegetation, where it exists and what changes are occurring. 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. This dataset is produced for the Government of Alberta and is available to the general public. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset.This dataset covers the areas of Alberta where there is both AVI and LiDAR coverage (mainly in the Green Area). AVIE and LiDAR-derived slope position were created by the Forest Resource Analysis Section, Forest Management Branch, Agriculture and Forestry. Rules used to classify the data were developed by the Range Resource Stewardship Section, Land Policy Branch, Environment and Parks.

Data Quality Information
Scope (quality information applies to): Dataset
Data History: Forest Management Branch (FMB) consolidated all available AVI into a single feature class, with a set of extended attributes (AVIE). Using a LiDAR derived 5m DEM, the landscape was classified into 6 slope position classes (1=valley, 2=lower slope, 3=flat slope, 4=mid slope, 5=upper slope and 6=ridge).Using attributes from AVIE (NSR2005, MOIST_REG, SP1, SP2, USP1, NFL, UNFL, ANTH_VEG, UANTH_VEG, ANTH_NON, UANTH_NON, NAT_NON, UNAT_NON, PCT_CONIF, UPCT_CONIF, MOD1) and a 6-class slope position dataset derived from a 5m LiDAR DEM (or Base Features 25M DEM), rules were created to derive mapcode and ecosite phase within the AVI polygons.
