Significant Woodlands & Significant Wildlife Habitat Study
STUDY RATIONALE
1. Provincial Policy Statements (1997, 2005) identify Significant Woodlands (SW) and Significant Wildlife Habitat (SWH) as features for which municipalities are required to identify and develop policies
2. Current Regional Official Plan and Town of Caledon Official Plan:• Significant Woodlands policies require review and updating• No specific policies for Significant Wildlife Habitat
3. To provide a technical basis to support and guide policy development in both the Region and Town of Caledon
Significant Woodlands & Significant Wildlife Habitat Study
STUDY DELIVERABLES
• Analysis of woodland cover and wildlife habitat on a Region and Town-wide basis
• Criteria and thresholds for mapping significant woodlands and significant wildlife habitat
• Guidance for policy development at Regional and Town levels
• Technical Study Report (October 2008)
Significant Woodlands & Significant Wildlife Habitat Study
CONSULTATION
1. Caledon Council Workshops• Apr. 9th and May 13th
2. Stakeholder Workshops• Apr. 7th and June 13th
3. Presentations to Community Groups• PFA, Caledon Agricultural Advisory Committee
(CAAC), Etobicoke-Mimico River Coalition and Humber River Alliance

Significant Woodlands Component
Long List of Preliminary Criteria• Started with 18 preliminary criteria derived from consultations
& background review
• Consideration of Evaluation Questions• Is criterion defensible?• Can criterion be quantified?• Are data available to apply criterion?• Are there known thresholds?• Are field data required to apply criterion?
• Input from MSWG, TAT, Stakeholders & Caledon Council
• 6 criteria are recommended for the identification of SWResults of Evaluation

KEY CHALLENGES
1. Developing thresholds for criteria that are:• appropriate for Caledon and / or Peel in the absence
of comprehensive data, and• defensible in the absence of comprehensive data.
2. Developing thresholds or approach to criteria implementation that are practical (i.e., can be applied with existing data or confirmed with site-specific data).
3. Ensuring consistency with Provincial direction (through ongoing consultations with OMNR).
Significant Wildlife Habitat Component
41 CRITERIA CONSIDERED

with ROP policies and PPS• Developed “Proposed Methodology to
Update Mapping of Core Valley and Stream Corridors”– Jointly developed with Area Municipal Staff– Provides basis/criteria for identification
Natural Heritage Policy Review
Policy 2.1.4
Development and site alteration shall not be permitted in:
c) significant valleylands south and east of the Canadian Shield.
Valleylands : means a natural area that occurs in a valley or other landform depression that has water flowing through or standing for some period of the year.
Significant means:
d) in regard to other features and areas in policy 2.1, ecologiallyimportant in terms of features, functions, representation or amount, and contributing to the quality and diversity of an identifiable geographic area or natural heritage system.
Criteria for determining significance for the resources identified in sections (c) – (g) are recommended by the Province, but municipal approaches that achieve or exceed the same objective may also be used.
Provincial Policy Statement
Natural Heritage Policy Review
ROP PolicyPolicy 2.3.2.2 (Core Valley and Stream Corridors)
Define the Core Areas of the Greenlands System in Peel as:
g) Only those valley and stream corridors shown on Schedule A associated with the main branches of the Credit River, the EtobicokeCreek, the Mimico Creek, the West Humber River, and the Humber River and with the other identified watercourses draining directly to Lake Ontario; except for those portions of the Rural Service Centresand the rural settlements in the Rural System as designated in an area municipal official plan. These valley and stream corridors are continuous linkages connecting to other elements of the GreenlandsSystem Core Areas. The width of all of these valley and stream corridors shall be determined in accordance with the definition in the Glossary of this Plan. Their length shall be determined in accordance with Schedule A.
Natural Heritage Policy Review
ROP PolicyGlossary Definition
Valley and Stream Corridors: valley and stream corridors are the natural resources associated with the river systems characterized by their landform, features and functions, and include associated ravines. Valley corridors and ravines are distinguished from stream corridors by the presence of a distinct landform. The limit of valley and stream corridors shall be determined, jointly with the area municipalties, on a site specific basis by the conservation authorities.
Natural Heritage Policy Review
Core Valleylands• Identified for their Regional significance
based on:– providing important ecological functions that
are regional in scale;– containing habitat (aquatic) for endangered
or threatened species; and– providing linkages to other Core Areas of
the Greenlands System across municipal boundaries
Natural Heritage Policy Review
• Consistent with ROPA 13• Policy revisions, criteria and
mapping to identify Core valleylands:– Main branches, major tributaries,
other tributaries and urban ravines
– Identifies defined valley system meeting criteria for Core valleylands (Crest of Slope)

Regional Official PlanGreenlands System
Policies
Policy 2.3.2.1It is the policy of Regional Council to define the GreenlandsSystem in Peel as being made up of:
• Core Areas
- protected in ROP and area municipal official plans
- “development and site alteration” is not permitted
- are considered “Regionally significant”
•Natural Areas and Corridors (NACs)
- ROP provides guidance to area municipalities
- NACs are interpreted, identified and protected through area municipal official plans
•Potential Natural Areas and Corridors (PNACs)
- require studies to determine significance
- PNACs are interpreted, identified and protected through area municipal official plans
- could be identified as Core Areas or NACs or not significant
• unevaluated wetlands• all other woodlands• provincial earth science ANSIs• sensitive groundwater recharge areas• valley and stream corridors < 125 ha drainage area• historic shorelines• open space portions of the Parkway Belt West Plan• potential ESAs
• Class 4 to 7 wetlands• woodlands 3 ha to 30 ha• Lake Ontario shoreline and littoral zone• non-Core valley and stream corridors > 125 ha drainage area• Escarpment Protection Areas• headwater source and discharge areas• other natural features interpreted by the area municipalities
• provincially significant wetlands (Class 1 to 3)• woodlands > 30 ha• ESAs• provincial life science ANSIs• habitat of vulnerable, threatened and endangered species• Escarpment Natural Areas• valley and stream corridors shown on Schedule A
