Vegetation Structure

Vegetation structure (VegStructure attribute in the database) identifies the tallest growth form that has at least 25% total cover. The four treed classes were forest, woodland, sparsely treed, or heterogeneous woodland and sparsely treed mixtures. The treed classes were determined according to the average estimated percent cover. To be considered a treed polygon, a minimum 10% cover of trees taller than 2 m was needed.

The untreed classes were tall shrub, low vegetation, emergent and non-vegetated (H = human; W = water) class. Young regenerating burns were assigned to the recent burn class if information regarding the current dominant growth form was unavailable from the source data. Some small islands in waterbodies were not classified. Table 6.3A-1 provides the photointerpretation criteria for each vegetation structure class.

Land Type and Ecosite Type

The ecosite classification used for ecosystem and habitat mapping was developed from soil sampling and photointerpretation conducted in the Keeyask, LNR downstream and Wuskwatim areas. The ecosite classes reflect important ecological differences in soil properties, hydrology and permafrost. The peatland classes are somewhat adapted from the Canadian Wetland Classification System (National Wetlands Working Group 1997). The site and ecosite classifications used to classify soil profile samples and map polygons were developed to be compatible with each other to the extent this made ecological sense given the differences in spatial scale. Land type represented a more general grouping of different ecosite types, for example, shallow and wet peatlands are grouped into “peatland”. The coarse ecosite type criteria and derived land type and broad ecosite types are provided in Table 6.3A-2.

Broad Vegetation Type

This derived variable identifies the leading vegetation species, and the degree of mixture with other types of species. For example, “black spruce mixedwood” refers to a treed stand with black spruce as the leading species, mixed with a broadleaf component greater than or equal to 30% of the canopy closure.

Vegetation Class

Vegetation class was derived by aggregating broad vegetation types into more general classes. For example, treed broad vegetation types with broadleaf species such as trembling aspen or white birch would be grouped into the vegetation class “Broadleaf Treed”.

Broad Habitat Type

The broad habitat variable is derived by combining broad vegetation type and coarse ecosite type. The resulting value indicates the vegetation composition of a polygon, along with the type of ecosite it occurs on (e.g., black spruce on shallow peatland). This classification is more detailed than coarse habitat, and is the variable that priority habitat types are based on.



Coarse Habitat Type

This derived variable combines broad habitat types into more general classes. It includes the specific

dominant conifer species and identifies mixedwoods, and provides a more detailed ecosite association,

such as “black spruce mixedwood on shallow peatland”.

Land Cover Type

This derived variable combines coarse habitat types into more general classes. It provides the general

vegetation cover type (e.g., needleleaf treed or broadleaf treed) and the land type association, such as

“peatland” or “mineral or thin peatlands”. This represents the most general habitat class in the ecological

land classification.

APPENDIX 6.4A:

WATERFOWL HABITAT MODEL METHODS



Two waterfowl habitat models were developed, a regional habitat model and an on-system habitat model.

The regional habitat model included data modified from the Forest Resource Inventory and National

Topographic System from both waterbodies regulated by Manitoba Hydro and not regulated. Details on

habitat mapping can be found in Terrestrial Habitat, Section 6.3.1.5. Waterfowl habitat was divided into

primary (high quality) and secondary (lower quality) classes based on general waterfowl habitat

requirements. The regional primary waterfowl habitat model included the Coarse Habitat types “Marsh”,

“Nelson River marsh”, and “Off-system marsh”. These habitat classes were chosen to be representative

of waterfowl breeding and brood-rearing habitat. The regional secondary waterfowl habitat model

included the Coarse Habitat types “Water” (Deep Water) and “Shallow water”. These habitat classes were

chosen to be representative of waterfowl staging habitat. Descriptions of the habitat types used in the

regional habitat models can be found in Terrestrial Habitat, Section 6.3.1.5.

The amount of waterfowl habitat that existed under infrastructure and flooding prior to human

development was unknown. To estimate the amount of waterfowl habitat lost in the post-hydroelectric

development period, the proportion of disturbance was calculated in each Terrestrial Region and

ecozone. This proportion of disturbance was considered the proportion of waterfowl habitat lost in the

Terrestrial Region or ecozone.

For the regional habitat model, multiple source datasets, using varying mapping standards and photo

years, were consolidated into a single detailed terrestrial habitat dataset, which encompassed the

southern two-third of the RCEA ROI. Due to the variability in the source data, primary and secondary

habitat quality could not be mapped on consistent basis throughout the detailed terrestrial habitat

mapping area. In some areas, the level of detail needed to classify waterfowl habitat was not available.

These limitations may explain why habitat may appear to be absent in portions of some regions. For

regional waterfowl habitat in northern zones and outside the mapped Forest Resource Inventory,

classified satellite imagery was used to define marsh habitat.

The on-system habitat models used data mapped from remotely-sensed imagery within waterbodies

regulated by Manitoba Hydro; details on habitat mapping can be found in Terrestrial Habitat, Section

6.3.1.5. As on-system habitat data were not complete in each Terrestrial Region, only areas that

contained data from the pre- and post-hydroelectric period were used. This method allowed for an

accurate representation of waterfowl habitat changes in each Terrestrial Region. Wetland habitat in the

on-system data were divided into two distinct zones: Shore Zone Wetland and Offshore Wetland

(Terrestrial Habitat, Section 6.3.1.5). The Shore Zone Wetland data classes were used to develop

primary and secondary waterfowl habitat models, and Offshore Wetland data classes were only used for

primary waterfowl habitat models. Both the Shore Zone and Offshore primary waterfowl habitat models

used “Marsh”, "Wide Marsh", “Very Wide Marsh”, "Marsh on sunken peat", “Pondweed”, and “Delta”

dominated habitat types. These habitat classes were chosen to be representative of waterfowl breeding

and brood-rearing habitat. The Shore Zone secondary waterfowl habitat used "Water" (Shallow Water)

dominated habitat types, and was representative of staging habitat. Descriptions of the habitat types in

the on-system habitat models can be found in Terrestrial Habitat, Section 6.3.1.5.

Examples of Shore Zone and Offshore primary waterfowl habitats are shown in Photos 6.4A-1 to 5.
