APPENDIX 1 : RARE SPECIES STATUS .108 1. PROGRAM ORGANIZATION AND FUNDING: The Muskoka Heritage Areas Program was established to identify the best examples of the District's natural and cultural heritage, using a systematic, 6bjective evaluation process, and to seek mechanisms for the protection of these heritage landscapes. 1992 was the third year of a planned three-year program, with field activities relating to natural heritage features, both biotic and scenic. Evaluation of cultural heritage also began in 1992. This report provides a preliminary analysis of the significance of biotic candidates studied in 1992 by the Heritage Areas field crew. The final evaluation of all candidates will t~ke place early in 1993, after field work has been completed. A review of technical measures such as regional rarity of species, the diversity/area index, and the percentage of introduced species will be carried out in preparation for this final evaluation. Evaluation of heritage areas is guid~d by a series of selection criteria, approved by District Council in March 1990 after review by various agency staff and interest groups. (Table 1) Program direction is provided by a Technical Steering Committee, with representation from the District Municipality, the Muskoka Heritage Foundation, the Ministry of Natural Resources Bracebridge Area office and Central Region (Huntsville). The 1992 field program had two major components: i) A Muskoka Scenic Evaluation was carried out by staff of the Heritage Areas Program, primarily through an Environmental Youth Corps grant. This project measured public responses to a "Scenic Muskoka" questionnaire, to determine public preferences for various landscape types, and to solicit specific nominations for sceni~ areas. A second part of the project used field surveys to evaluate and document the nominated areas, and to identify additional similar landscapes that would meet the expressed public preferences. Resu'l ts of th i s study have been sunmar i zed ina separate report. ii) The third year of the biological field program, at a cost of approximately $65,000, was co-sponsored by the District Municipality, the Ministry of Natural - 1 Resources, and the Muskoka Heritage Foundation. Additional support for this program included: * The provision of an Environmental Youth Corps grant from the Ontario Ministry of Environment to hire one field assistant and one data input person; * A three-year grant provided by Wildlife Habitat Canada to assist with landowner contact and stewardship components of the program. * A supporting grant provided by World Wildlife Fund (Canada) under the Endangered Spaces program; * A supporting grant from The McLean Foundation, through the Muskoka Heritage Foundation. The 1992 biological field program was carried out by a seasonal field crew based in Bracebridge. Field work included ten candidate areas, plus more limited reconnaissance of another twelve areas. Results of this field work are included in this report. Field staff for 1992 included: Project Coordinator: Ron Reid, Bobolink Enterprises Field Chief: Bonnie Bergsma Field Assistant: Terry Rasmussen Data Input: Genevieve Taeger Field work and specimen identification was also assisted on several occasions by the volunteer input of Bill Crins, Jan McDonnell, Adriane Pollard, Dan Whittam, and several members of the Muskoka Field Natura.lists. - 2 Table DISTRICT OF MUSKOKA HERITAGE AREAS SELECTION CRITERIA January 1990 AS/OTIC CRITERIA: Objective: To identify a system of physical landscapes that incorporate the full diversity of bedrock, surficial, and aquatic landform types and features within Muskoka. 1. The area has landform features or elements that are distinctive or unusual in the District, Ontario, or Canada. 2. The area is representative of at least one landform type, process, or phase of development not adequately represented within existing protected areas. 3. The area exhibits unusually high diversity of landform features or types. 4. The area contributes to regional hydrological systems through ground or surface water storage or protection or enhancement of water quality. BIOTIC CRITERIA: Objective: To identify in a systematic way the best examples of the full range of Muskoka's biological heritage, including both aquatic and terrestrial habitats critical to the survival of healthy populations of native wild species. 1. The area is representative of at least one biotic community type not adequately represented within existing protected areas. 2. The area exhibits high diversity of native flora and fauna, either at the species or community level. 3. The area contains biotic communities of unusually high quality or showing little recent disturbance, or remnants of community types greatly reduced from their earlier distribution. - 3 4. The area provides habitat for species of plants or animals that are rare, threatened, endangered, or vulnerable in the District, Ontario, or Canada. 5. The area serves as a breeding, shelter, or feeding site for seasonal concentrations of wildlife or fish. 6. The area is large enough to support species requiring extensive undisturbed habitats, or provides linkages between other significant natural areas. CULTURAL CRITERIA: Objective: To identify a system of significant cultural landscapes and features within Muskoka, including historic and contemporary elements. 1. The area is representative of an historic or prehistoric theme or process significant to the development of Muskoka. 2. The area contains sites or landscapes associated with well-known events or people, or distinctive ethnic groups. 3. The area contains buildings, artifacts, travel routes, or landscape'patterns of relative antiquity or duration. 4. The area exhibits cultural characteristics unusual or unique to Muskoka, possessing high artistic values, or embodying distinctive examples of a type, period, or method of construction. s. The area contains elements that reflect the distinctive values, attitudes, traditions, and lifeways of the people of Muskoka. 6. The area has high archaeological potential, or known archaeological significance. 7. The area contains sites or landscapes with patterns of form, line, colour, or texture that together present outstanding scenic value. - 4 2. METHODOLOGY FOR BIOTIC FIELD PROGRAM: 2.1 Selection of Candidate study Areas: Candidate study areas were selected on the basis of: i) local knowledge of significant or interesting features; ii) previous records of rare species from the National Museum Atlas of Rare Vascular Plants, the Ontario Herpetofaunal Summary, or the Ontario Breeding Bird Atla~; iii) distinctive or unusual landform features which could be combined with potential biotic significance; iv) representation of biotic types not adequately represented within existing protected areas; v) candidates identified during previous studies for potential park status, ANSI designation, or Atlantic coastal plain species. 2.2 Boundary Delineation: Tentative site boundaries were established using air photo analysis and preliminary site visits. Boundaries were refined and confirmed during field study. Limited buffers were added where it was necessary to protect sensitive ecological areas (such as wetlands, habitat for sensitive species, forest interiors) by increasing their margins. On the individual Heritage Area maps, buffers have been noted with broken dash lines. Although final boundary and buffer delineation was made on Ontario Base Maps at a 1:10,000 scale~ all boundaries must be considered as approximate. In defining boundaries, the following guidelines were used: i) boundaries should incorporate the full range of natural heritage features present; ii) boundaries should follow the edge of significant geological features or habitat types; iii) where no habitat boundary is apparant, - 5 boundaries should follow watershed or sub watershed limits, ridges, or other distinctive topographical features recognizable in the field; iv) where appropriate, boundaries should follow cultural delineations such as roads, railways, or hydro lines; v) in some cases, boundaries may be influenced by property boundaries, particularly between Crown and private lands, although this is a secondary consideration; vi) boundaries should generally exclude developed and agricultural areas, although scattered
