Climate Change Vulnerability Index
Table 1: Vulnerability to climate change of 37 species included in the State Wildlife Action Plan for Pennsylvania and 29 plant species found in Pennsylvania. The species are ordered by preliminary CCVI score then S-rank. Please refer to the definitions of index scores when interpreting the results (located at the Table’s end).
Definitions of CCVI Scores
Extremely Vulnerable: Abundance and/or range extent within geographical area assessed extremely likely to substantially decrease or disappear by 2050.
Highly Vulnerable: Abundance and/or range extent within geographical area assessed likely to decrease significantly by 2050.
Moderately Vulnerable: Abundance and/or range extent within geographical area assessed likely to decrease by 2050.
Not Vulnerable/Presumed Stable: Available evidence does not suggest that abundance and/or range extent within the geographic area assessed will change (increase/decrease) substantially by 2050. Actual range boundaries may change.
Not Vulnerable/Increase Likely: Available evidence suggests that abundance and/or range extent within geographic area assessed is likely to increase by 2050.
