Example of dominant Woodland ecosystem
with a secondary Herbaceous ecosystem
Ecosystem composition is complex and often contains a dominant ecosystem with 
secondary and tertiary ecosystems. In this map the dominant ecosystem has a solid
shading and the secondary and tertiary ecosystems are identified by hatched lines.
Sensitive ecosystems are fragile and/or rare, or are ecologically important because of the diversity of species they support.
Sensitive Ecosystems
Subclasses:
Importance:
Subclasses:
Non-forested ecosystems (less than 10% tree cover), generally with shallow soils. They include bedrock outcroppings, large 
openings within forested areas, spits, dunes and shorelines vegetetated with grasses and herbs.
Importance:
Subclasses:
Importance:
Areas adjacent to water bodies (rivers, lakes, ocean, wetlands) which are influenced by factors such as erosion,
sedimentation, flooding and/or subterranean irrigation due to proximity to the water body. Structural stages 1 - 7.
Areas that are saturated or inundated with water for long enough periods of time to develop vegetation. This may result from
flooding, fluctuating water tables, tidal influences or poor drainage conditions.
Importance:
Subclasses:
Importance:
Subclasses:
Very steep slope, often exposed bedrock, may include steep-sided sand bluffs.
Importance:
Subclasses:
Freshwater ecosystem includes bodies of water such as lakes and ponds that usually lack floating vegetation.
Importance:
Subclasses:
Areas that link the marine and terrestrial environments and generally consist of mudflats and beaches.
Importance:
Subclasses:
Other Important Ecosystems
Usually conifer-dominated, occasionally deciduous, dry to moist forest types, structural stage 6, generally >80yrs.
On this map, Young Forest ecosystems are depicted ONLY when they occur in a mosaic with other sensitive ecosystems. For example,
a Young Forest dominates the polygon but there is also a distinct wetland within the polygon boundary.
Other Mapped Ecosystems
Mature Forest (MF):
Other important ecosystems have high biodiversity values.
Woodlands are nationally, provincially and regionally rare and highly fragmented . A rich assemblage of plants, insects,
reptiles and birds are drawn to these ecosystems due to the food sources, habitat and proximity to the ocean. Garry oak
woodlands, for example support the highest plant species diversity of any terrestrial ecosystem in British Columbia and
are especially vulnerable to rural development.
Terrestrial Herbaceous ecosystems are characterized by thin
