Structural Stage1
1 Sparse/bryoid Substages 1a Sparse 1b Bryoid 2 Herb Substages 2a Forb-dominated 2b Graminoid-dominated 2c Aquatic 2d Dwarf shrub 3 Shrub/Herb Substages 3a Low shrub; less than 2 m. tall 3 Tall shrub; 2 – 10 m. tall 4 Pole/Sapling Trees > 10 m. tall; typically densely stocked
5 Young Forest
Generally 40 – 80 years old depending on species and ecological conditions; forest canopy has begun to differentiate
6 Mature Forest Generally 80 – 250 years since last disturbance; understory becomes well developed as canopy opens up; shade tolerant trees established
7 Old Forest Generally over 250 years since last disturbance; structurally complex stands; Coarse woody debris (CWD) common.
1 In the assessment of structural stage, structural features and age criteria are considered together. Broadleaf stands will generally be younger than coniferous stands belonging to the same structural stage.

Ecosystem Components
Some polygon labels will have class and subclass repeated up to three times. This is not an error; it reflects the variability in site units and structural stages occurring within a polygon. More than one site unit can be correlated to a SE class and subclass. Polygon labels on the map do not include the site units. The Sensitive and Terrestrial Ecosystem Labels on the left side of the map provide details about site units mapped in each polygon.
This cartographic product uses Dot Density to indicate where more than oneecosystem class is mapped in a polygon. The number of dots indicates theproportion of the polygon represented by the 2nd and 3rd ecosystem; the colourof the dots indicates the 2nd and 3rd ecosystem class.
The base colour represents the first ecosystem component.
Coloured dots overlaid upon the base colour indicate asecond ecosystem component.
Two colours of dots indicate a second and third ecosystem.

What is a Sensitive Ecosystem?
For the purpose of this study, an ecosystem is considered to be a portion of the landscape with
relatively uniform dominant vegetation.
Sensitive ecosystems are those which are fragile and/or rare, or those ecosystems which are
ecologically important because of the diversity of species they support.
Rationale Ecologically significant lands and important wildlife habitats are fast disappearing throughout the lowlands surrounding the Strait of Georgia. Intense development pressures fuelled by population and economic growth have fragmented and degraded many terrestrial ecosystems. A high proportion of these ecosystems are now designated as “at risk”. Sensitive ecosystems typically have high biological diversity and are a vital part of the landscape. They provide ecosystem services for a healthy economy and for social well being. They regulate climate, clean water, generate and clean soils, recycle nutrients and pollinate our crops. To protect these areas, sensitive ecosystems must be located, identified and mapped. Along the Sunshine Coast the wave-beaten shorelines, coastal plains, rugged mountain slopes, fjords and estuaries contribute to high biodiversity values. Here one finds coastal temperate rainforests, dry shoreline woodlands, herbaceous meadows and rocky coastal bluffs, wetlands and riparian ecosystems.
Purpose The purpose of the Sensitive Ecosystems Inventory (SEI) of the Sunshine Coast is to identify, classify and map sensitive terrestrial ecosystems along the coastal lowlands (including the adjacent islands) from Howe Sound to Desolation Sound. The goal of the SEI is to encourage informed land-use decisions that will conserve sensitive ecosystems. The SEI on Vancouver Island and Gulf Islands (1993 – 1997) shows that this information can be used in a variety of land-use planning processes and can contribute to the conservation of many sites. Decision makers, consultants and non-government organizations have found the SEI to be an effective planning and management tool. SEI data provides site-specific ecological information that can be used to flag sites of conservation concern, to prompt detailed field studies prior to development projects, and to provide input to Forest Stewardship Plans.
MethodologyThe mapping methods are based on the Vancouver Island SEI project and the Resources Information Standards Committee (RISC) Standard for Terrestrial Ecosystem Mapping (TEM) in BC. Ecosystem categories include six Sensitive Ecosystem (SE) classes, two Important Ecosystem classes, and one Other Ecosystem class. The legend to the right of the map provides definitions. Ecosystem classes, subclasses, the corresponding Terrestrial Ecosystem site units and structural stages, and stream and drainage corridors not included in TRIM, are mapped. Field survey protocols followed Describing Terrestrial Ecosystems in the Field (RISC 1998) with the addition of a conservation evaluation form to document ecosystem condition and viability. Approximately 20% of the polygons were field checked.
Data Limitations The SEI is a tool to alert decision makers to the existence of sensitive ecosystems, however when land-use changes are proposed detailed site-level assessments are necessary. For sites not field checked, the accuracy of the data depends heavily on the professional judgement of the mapper and the availability of source data. Because the area is changing rapidly, reference to the date of the information source is advised. Aerial photographs used were flown between 1994 and 1999, most are at 1:10,000 scale, some at 1:16,000 scale. Due to the mapping scale, minimum polygon size is usually ½ hectare. Minimum riparian polygon width is 20 metres regardless of the stream channel width. Enlargement of the data beyond the source scale may result in unacceptable distortion and faulty registration with other data sets.
What can be done to protect sensitive ecosystems? Direct and indirect impacts to these ecosystems can be avoided by: • Retaining or creating vegetated buffers around sensitive
ecosystems to isolate them from outside disturbance; • Controlling land and water access to fragile ecosystems; • Controlling invasive species; • Allowing natural disturbances to occur; • Maintaining water quality.
If development must occur, develop carefully!
Conduct an ecological inventory to identify the existing flora and fauna and to locate any threatened or endangered plant and animal species, plant communities, and habitat features needing protection;
Plan and implement all development activities in a manner that will not adversely affect or disturb the sensitive ecosystem.
Consult a qualified professional to interpret the ecological inventory data and work to incorporate designs that maintain the functions and values of the natural ecosystem.
If you are:
A property owner: learn more about the natural values of your land, including the location of any sensitive ecosystems. Find out how to protect, maintain, and enhance those values. Consider using conservation covenants or other measures to ensure that the natural features you value are protected in perpetuity.
A developer: consider a design for your project that is creative and flexible enough to protect and enhance sensitive ecosystems. Treed lots and neighbourhood greenspaces can increase market values.
A planner: ensure that conservation is given as high a priority asother community programs such as housing, transportation, recreation, employment, public works, and community services. Encourage use of the many legal and planning tools available, such as development permit areas, tree protection by-laws, and conservation covenants to protect sensitive ecosystems.
A decision-maker (such as a politician or resource manager): ensure that protection of remaining sensitive ecosystems is a priority at all levels, and support programs, plans and operational activity that will help protect sensitive ecosystems. Encourage and facilitate the development and implementation of biodiversity conservation strategies.
A member of an advocacy group: contribute your time and expertise to help locate and protect sensitive ecosystems. For example, ratepayers’ groups, service organizations, naturalist clubs, land trusts, and conservancies often provide a link between local landowners and voluntary stewardship programs. As a member of one of these groups, you can work cooperatively with local governments to promote land use decisions that protect sensitive ecosystems.
A volunteer: participate in educational programs, conservation fundraising, or in programs to remove invasive species.
A scientist: use your expertise to help identify sensitive ecosystems, define issues that need to be addressed, formulate conservation plans, contribute to the development of conservation andmanagement strategies and explain to other professionals and decision makers the importance of sensitive ecosystems.
