CENTRAL INTERIOR ERA: Map 2: Central Interior Freshwater Study Area Ecological drainage units (EDU) are comprised of river ecosystems that share a common zoogeographic history and therefore likely have a distinct set of freshwater assemblages and habitats. The freshwater study area includes EDUs that have the majority of their area within the terrestrial boundary. Complete drainage systems were included in the analysis rather than cutting them at the terrestrial boundary and this resulted in a study area that is larger than its terrestrial counterpart. The area of the freshwater study area is 38,729,060 ha.

CENTRAL INTERIOR ERA: Map 13: Terrestrial Suitability Index / Vulnerability The objective of a suitability index is to prompt Marxan to select areas of lower threat to conservation when all other factors are equal, rather than randomly selecting less intact, fragmented, or less viable areas. The suitability index is a measure of human influence on the landscape and the level of threat from associated activities (logging, oil and gas development, urbanization, etc). Linear features (roads, railways, pipelines), which are directly linked to human activities and threats to conservation, were used to develop the suitability index layer. The areas of low suitability index value Scale 1:3,000,000 are areas with higher threats to conservation (higher density / proximity to roads). 0306015 Kilometres August 2010 Vulnerability is another way to view the suitability index. Areas that are Projection: BC Albers Equal Area highly suitable for conservation will have low vulnerability i.e. they are less vulnerable to threats. 0306015 Miles 133°W 132°W 131°W 130°W 129°W 128°W 127°W 126°W 125°W 124°W 123°W 122°W 121°W 120°W 119°W 118°W 117°W 59°N 59°N

CENTRAL INTERIOR ERA: Map 14: Freshwater Suitability Index / Vulnerability The objective of a suitability index is to prompt Marxan to select areas of lower threat to conservation when all other factors are equal, rather than randomly selecting less intact, fragmented, or less viable areas. The suitability index is a measure of human influence on the landscape and the level of associated threat to conservation value. Three threats to freshwater conservation value were used to develop the freshwater suitability index: road-stream crossings, water demand, and physical obstructions. The number of road-stream crossings was determined by intersecting streams with roads. Water demand was determined by subtracting the amount of Scale 1:3,700,000 water licenced from the amount of water available per watershed. The number of physical obstructions is from the dams and other diversion August 2010 datasets. The three factors were weighted according to the methods 0408020 Kilometres described in Holt et al. (2003) to obtain a single suitability index value for Projection: BC Albers Equal Area each watershed.
Vulnerability is another way to view the suitability index. Areas that are 0408020 Miles highly suitable for conservation will have low vulnerability i.e. they are less vulnerable to threats. 132°W 131°W 130°W 129°W 128°W 127°W 126°W 125°W 124°W 123°W 122°W 121°W 120°W 119°W 58°N 58°N

CENTRAL INTERIOR ERA: Map 15: Terrestrial Conservation Value
Conservation value is a measure of the rarity, diversity, richness, and irreplaceability of species targets located within the study area.
• Rarity is the average of global rank (GRank) scores for targets within each assessment unit. • Diversity is the number of different types of targets within each assessment unit divided by the total number of different types of targets within the ecoprovince. • Richness is the number of different targets per planning unit divided by the Scale 1:3,000,000 total number of different targets within the ecoprovince. • Irreplaceability is the average summed solution value for each assessment unit from six different Marxan runs without suitability index as cost layer 0306015 Kilometres August 2010 with all targets set at 5%, 10%, 20%, 30%, 40%, and 50% goals Projection: BC Albers Equal Area respectively.
These four factors were calculated, scaled between 0 and 1, and summed 0306015 Miles together to create the overall conservation value for each assessment unit. 133°W 132°W 131°W 130°W 129°W 128°W 127°W 126°W 125°W 124°W 123°W 122°W 121°W 120°W 119°W 118°W 117°W 59°N 59°N

CENTRAL INTERIOR ERA: Map 18: Terrestrial Summed Solution NCC Marxan Output
The summed solution output is the summation of the number of times an assessment unit was included in each of the 500 Marxan runs that were performed to determine the “best” NCC Marxan output. The summed solution is a good measure of hotspots across the landscape. It should be used alongside the “best” output.

Conservation value (map 16) and Vulnerability (map 14) were combined using a 4x4 matrix (see map legend) to prioritize the portfolio. Portfolio sites are numbered and ranked according to value and vulnerability.
The sites can be divided further into four categories: • Priority/Tier 1: high value, high vulnerability • Priority/Tier 2: high value, low vulnerability • Priority/Tier 3: low value, high vulnerability • Priority/Tier 4: low value, low vulnerability Scale 1:3,700,000

Dark red areas were selected more for climate change runs, and dark blue areas were selected more for NCC runs.

CENTRAL INTERIOR ERA: Map 30: Freshwater Climate Change Comparison with NCC Output This map shows the result of subtracting the climate change summed solution from the NCC summed solution output. Areas with higher (positive) value are areas that were selected more in NCC runs than Climate Change, and vice versa. Dark red areas were selected more for climate change runs, and dark blue areas were selected more for NCC runs.
Please note that grey areas (no change in selection between NCC and Climate Change runs) include any locked in planning units (protected areas). Scale 1:3,700,000

CENTRAL INTERIOR ERA: Map 31: Comparative Analysis - Terrestrial Portfolio & Climate Corridors
Climate corridors are locations where current habitat or species are predicted to persist throughout climate change. Climate modelling software (ClimateBC and ClimatePP) were used to generate future climate models to the 2080s. Areas called “suitable climate spaces” were identified; these are areas where climate is predicted to persist from the baseline (1961-1990s) to the 2080s. Areas where suitable climate spaces overlap with current distribution are the persistent climate corridors. Corridors were developed for both biogeoclimatic zones (based on BEC mapping) and rare plant species (based on occurrence data). All corridors are show on this map overlaid on the terrestrial portfolio. Scale 1:3,000,000

CENTRAL INTERIOR ERA: Map 34: Comparative Analysis - Wolverine Probability of Occupancy Model
Wolverine probability of occurrence models were developed for the Mackenzie, Fort St. James, Vanderhoof, and Prince George Forest Districts. These models show high value areas that are predicted to contain Wolverine.
This map shows the terrestrial portfolio overlaid with the Wolverine model.
