1 2C1Forest and Science-based Conservation: Overview of Phase 1 Accomplishments Justina C. Ray, WCS Canada

2 2C1Forest reinventing conservation for 21st Century Science-based, transboundary, landscape-scale conservation

3 A 2C1Forest Collaborative Project Mark Anderson Science Team, TNC lead Rob Baldwin 2C1Forest Scientist, Future Trends/Maine lead Karen Beazley Science Team, Dalhousie/NS lead Graham Forbes Science Team, UNB/NB lead Louise Gratton Science Team, NCC/Que. lead Justina Ray Science Team, WCS lead Conrad Reining Science Team, Wildlands lead Steve Trombulak Science Director, 2C1Forest/VT,NH,NY lead Gillian Woolmer HF 2000 lead, lead GIS analyst

4 Phase 1: Laying foundation for landscape- scale conservation strategy: priority locations Phase 2: Planning for connectivity and climate change in focal linkage areas

5 Regional Initiatives 1.Ecoregional Assessment  The Nature Conservancy & Nature Conservancy Canada 2.Wildlands Network  Wildlands Project 3.Human Footprint WCS Canada 4.Future Human Footprint 2040  2C1Forest

6 Conservation Planning Components  Importance: the extent to which locations on the landscape are replaceable with respect to achieving the conservation goals we have specified.  Vulnerabilility: extent and threat of conversion/transformation both now and in the future.

7 Measuring Importance Special ecosystems Representative land units Focal species Rare species

8 Ecoregional Planning Select Conservation Targets Fine Filter:Species Coarse Filter: Ecological Communities, Systems, and Physical Diversity Assess Viability of Target Occurrences Size Condition Landscape Context Set Representation and Redundancy Goals Number and Distribution

9 Geology Landforms Climate Elevation Landcover (ELU’s)

11 Irreplaceability  MARXAN site selection tool  1000 ha planning units  Protected Areas locked-in, Urban areas locked-out  Preference for public lands (incld. crown lands)  Conservation elements Focal species – lynx, marten and Wolf (Carroll, 2003 & 2005) Ecological variation (TNC/NCC)) Rare element occurrences (TNC/NCC)

23 Noss et al A Multicriteria Assessment of Irreplaceability and Vulnerability of Sites in the Greater Yellowstone ecosystem. Conservation Biology CONSERVATION PLANNING: SPATIAL PRIORITIZATION

24 3 Units of Analysis

25 Each planning unit has: 1 score for importance 4 scores for HF scenarios High Importance, Low Threat High Importance, High Threat Low importance, High Threat Low importance, Low Threat CUT-OFF Hi/Lo: MEDIAN SCORES URGENCY & OPPORTUNITY

26 Importance vs. Threat (current) at 10 km 2 scale

27 Importance vs. Threat (current) at Watershed scale

28 Importance vs. Threat (current) at Ecological Unit scale

29 Importance vs. Threat (Current HF) at 10 km 2 scale Importance vs. Threat (transition) at 10 km 2 scale

30 KEY PATTERNS  large areas that still retain characteristics of “wild” landscapes and that have not yet experienced permanent transformation to settlement,  large areas of permanent transformation that threaten and increasingly fragment the “wild” landscapes,  an increase in transformation in most locations under most future scenarios, and  areas of high irreplaceability and vulnerability across the region that are not currently protected or targeted for protection.

31 TAKE-HOME MESSAGES  Identifies the most urgent priorities in the form of conservation triage.  Identifies sites that are most likely to increase in vulnerability status, many of which lie within zones of connectivity between important relatively intact areas.  The selection of the planning unit has great bearing on the ultimate results in priority ranking, and must therefore be chosen carefully.  Individual layers that collectively contribute to assessments of irreplaceability and vulnerability should not disappear from view, and will be equally valuable to planners characterizing the landscape in question.
