1 CCVATCH Scoring Current Condition Sensitivity-Exposure Adaptive Capacity Overall

2 Instructions Instructions for Scoring 1 Describe habitats being assessed: Then, begin with Exposure X Sensitivity matrix and assign scores as follows: General Scoring [*Refer to guidance document for specific examples of how this scoring should be applied] a. Current Condition score (relative to non-climate stressor only) 0 Habitat is not impacted by non-climate stressor (=default value) 2 Habitat is currently impacted by non-climate stressor but to a limited degree (i.e. over a modest portion of its extent or no significant influence on habitat structure / function) 5 Habitat is currently moderately impacted by non-climate stressor (i.e. evidence of stressor impact over a majority portion of its extent or clear degradation of habitat structure / function) 10 Habitat is severely impacted by non-climate stressor b. Non-climate stressor interaction with CC stressors (i.e. with CO2, Temp, Precip, Sea Level, Storms) -2 Habitat may benefit 0 No anticipated change 2 Habitat will likely be impaired 5 Habitat persistence will be limited 10 Habitat will be lost *Note: The interaction of current condition and non-climate stressor interaction scores is captured in a relationship table [see Relationship Table worksheet]. Values in the relationship table are automatically extracted and contribute to the final score tally and weighted means.

3 Sensitivity-Exposure Habitat Current Cert. CO2 Cert. Temp Cert. Precip Cert. Sea Level Cert. Storms Cert. Direct Effects (Ecophysiological & Community Response) Invasive Species Nutrients (deficiency or excess) Sediments (Sedimentation or Erosion) Biological Contaminants (including HABs, pathogens, parasites) Chemical Contaminants Tool User Inputs: Current Condition, Sensitivity-Exposure Interactions,

4 Sensitivity-Exposure Current Condition Relates to non-climate stressor effect on habitat 0 Habitat is not impacted by non-climate stressor or extent of impact is unknown (= default value) 2 Habitat is currently impacted by non-climate stressor but to a limited degree (i.e. over a modest portion of its extent or no significant influence on habitat structure/function) 5 Habitat is currently moderately impacted by non-climate stressor (i.e. evidence of stressor impact over a majority portion of its extent or clear degradation of habitat structure/function) 10 Habitat is severely impacted by non-climate stressor

5 Sensitivity-Exposure Sensitivity-Exposure Interaction Relates to the direct effect of climate change and the interaction of climate-change on existing or anticipated non-climate stressors -2 Habitat may benefit 0 No anticipated change 2 Habitat will likely be impaired 5 Habitat persistence will be limited 10 Habitat will be lost

6 Relationship Table For each non-climate stressor, an output score is generated Sum of Sensitivity-Exposure Scores Current Condition <0 0 to 1 2 to 4 5 to The conversion of raw scores using the relationship table assumes: (1) the current condition of a habitat will influence its overall vulnerability (i.e. degraded habitats are potentially more vulnerable to the effects of climate change), and (2) the influence of multiple climate change stressors (e.g. CO2, temperature, precipitation) on habitat sensitivity is cumulative (i.e. habitats that are sensitive to a single CC stressor (based on anticipated exposure levels) are likely to be less vulnerable than those which are sensitive to multiple CC stressors.

7 Sensitivity-Exposure Relates to the basis and level of agreement among tool users for selected scores 4 Supported by multiple peer-reviewed literature which are in general agreement and directly apply to local habitats or there is unanimous agreement among the tool users and/or experts for the agreed-upon response based on the state of current knowledge 3 Supported by limited peer-reviewed literature which are assumed to apply locally or there is some uncertainty possible, but the team/experts feel confident in the chosen response 2 Based on expert opinion only and there is no unanimity among experts regarding the response chosen 1 Based on anecdotal observations or evidence and there is important disagreement among experts regarding the response chosen 0 No direct or anecdotal evidence is available, this is a best guess

8 Adaptive Capacity Habitat Degree of fragmentation Barriers to migration Dispersal and movement Recovery / regeneration Habitat Diversity of functional groups Management actions Institutional adaptive capacity Human responses

9 Adaptive Capacity Adaptive Capacity Relates to inherent traits or external factors that allows a habitat to adjust to a changing climate 5 No impediment to habitat persistence or dispersal (e.g. barriers, fragmentation) exists or innate community characteristics of the habitat are sufficient to overcome CC stressors or appropriate policy or management actions may be taken to fully offset CC stressors 2 Modest impediments to habitat persistence or dispersal (e.g. barriers, fragmentation) exist or innate community characteristics of the habitat are sufficient to partially overcome CC stressors or appropriate policy or management actions may be taken to partially offset CC stressors 0 Severe impediments to habitat persistence or dispersal (e.g. barriers, fragmentation exist or innate community characteristics of the habitat are not sufficient to compensate for CC stressors or policy or management actions to offset CC stressors are not possible or are likely to be implemented
