1. Background
The forest cover classification methodology was originally developed for the Landscape
Planning Pilot project (Olson and Diehl, 2000). There was a need to roll up the AVI
stand calls into a more general description in order to predict ecosite phase. That original
forest cover classification covered only the species and landscape classes found in the
Southern Rockies (FMU’s C5, CO1, and CO2). These classes were added to and
expanded to include species and classes found in other parts of Alberta.
The forest cover classification program is written in .AML and is intended to be run from
within ArcInfo workstation, from the Arc prompt. The .AML program anticipates that
the AVI attribute information is stored in INFO.
2. Input Data Requirements
The provincial AVI 2.1 data model is the required format for the input data set for the
forest cover classification. The required fields are as follows:

5. General Classification Methodology
The forest cover classification procedure is broken up into several different sections.
5.1. Species Roll-up
The Species Roll-up section is a preparatory section that tabulates the amount of each
species in both the understory and overstory of a stand call. These species percentage
fields facilitate the forest cover classification queries in the next four sections.
5.2. Forest Cover – No Structure
A first-cut classification is done on the overstory call of all stands, irregardless of stand
structure type and understory call. These queries are used to populate the field
FC_NOSTR.

6
5.3. Forest Cover – Horizontal Stands
All horizontal stands (STRUC = H) are examined. Those stands having an understory
call containing > 50% of the polygon and containing tree species will be classified. The
classification field is FC_H_STR.
5.4. Forest Cover – Multistory Stands
All multistory stands having an ‘A’ density overstory and a forested understory with a
density greater than ‘A’ will be examined and classified. The classification field is
FC_M_STR.
5.5. Forest Cover – Understory Grasslands
This classification is intended to target complex grassland structures of horizontal and
multistory stands. The classification field is UGRASS. The following types of stands are
examined:
Non-forested closed shrub lands where shrub coverage is < 60%, no structure
is noted, and no understory non-forested call is noted.
Horizontal and multistory stands where the overstory is forested, no
understory non-forested call is present, and understory anthropogenic
vegetation is either rough pasture or not populated.
Non-forested closed shrub lands where shrub coverage is < 60%, no structure
is noted, and an understory non-forested call is noted.
Understory shrub calls with an understory anthropogenic vegetation call.
Understory herbaceous grass calls with wet or aquatic moisture regimes.
Any understory call of anthropogenic vegetation.
Any understory call of herbaceous grass.
Any understory call of anthropogenic non-vegetated land.
Any understory call on naturally non-vegetated land.
5.6. Final Classification
The final classification step assigns the calls from FC_NOSTR, FC_H_STR, FC_M_STR, and
UGRASS to the dominant and sub-dominant forest cover classes. The dominant and sub-
dominant and then concatenated into a complex forest cover class.
Dominant forest cover was considered as:
FC_NOSTR where no horizontal or multistory call was made.
FC_H_STR where a horizontal class was calculated..
FC_M_STR where a multistory class was calculated.
Sub-dominant forest cover was considered as:
FC_NOSTR where a horizontal or multistory class was calculated.
UGRASS where an understory grass class was calculated.
6. Wetlands Prediction
The original Landscape Planning Pilot forest cover classification procedure (Olson and
Diehl, 2000) classified only shrub wetlands and a generic spruce wetland type. Upon
expanding the forest cover classification procedure to the rest of the province, the

7
opportunity presented itself to be able to predict additional types of wetlands, which
might represent distinct ecological land types. Personal communication with Grant
Klappstein and Leonard Barnhardt of the Forest Management Branch of Alberta
Sustainable Resource Development facilitated definition of four types of forested
wetlands that could be predicted from AVI stand calls: black spruce wetland, white
spruce wetland, larch tamarack wetland, black spruce/larch tamarack wetland. Although
all wetland classes have a “wet” or “aquatic” moisture regime, it should be noted that not
all “wet” forested stands receive a wetland-type classification.
The following criteria were used to define the forested wetland types:
Black Spruce Wetland
Dominant presence of Black Spruce
No presence of Larch
No presence of White Spruce
No presence of Fir species
≤ 20% Lodgepole/Jack Pine
No presence of Aspen
≤ 10% Poplar
≤ 20% Birch
Cumulative presence of deciduous species ≤ 20%
White Spruce Wetland
Presence of White Spruce (≥ 20%) in a spruce wetland
< 50% Larch present
≤ 10% Poplar
≤ 20% Birch
FC_NOSTR must not be already classified as “Black Spruce Wetland”
Larch Tamarack Wetland
Dominant Larch presence (≥ 80%)
< 50% Black Spruce in both the overstory and understory
< 50% White Spruce
≤ 10% Poplar
≤ 20% Birch
Black Spruce/Larch Tamarack Wetland

8
≤ 10% Poplar
≤ 20% Birch
AND
≥ 10% and < 80% Larch
≥ 10% Black Spruce
OR
Overstory or understory presence of Larch
Overstory presence of Black Spruce
OR
Overstory ≥ 30% Black Spruce or understory ≥ 50% Black Spruce
FC_NOSTR contains some type of Larch class
