2
Resiliency: large populations able to withstand stochastic eventsAdequate water quality and quantity; sufficient herbaceous groundcover and sufficient habitats with suitable soils.Of the 13 known populations, 4 highly and 5 moderately resilient populations.Overall:Loss of 4-6 high and moderately resilient populations by 2070
Status quo:3 highly and 2 moderately resilient populations by 2070
Intermediate:2 highly and 2 moderately resilient populations by 2070
High:1 highly and 2 moderately resilient populations by 2070
3
Redundancy: number and distribution of populations to withstand catastrophic eventsMultiple resilient populations throughout the eastern and western portions of range of the species.Overall, 54% reduction in habitat throughout range from historic levels. 1 highly and 3 moderately resilient populations in the west; 3 highly and 2 moderately resilient populations in the east.Overall:By 2030, 33-44% reduction in resilient populations; by 2050 and 2070, 44-66% reduction in resilient populations
Status quo:By 2070, 0 highly and 1 moderately resilient populations in the west; 3 highly and 1 moderately resilient populations in the east
Intermediate:By 2070, 0 highly and 1 moderately resilient populations in the west; 2 highly and 1 moderately resilient populations in the east
High:By 2070, 0 resilient populations in the west; 1 highly and 2 moderately resilient populations in the east
4
Representation: genetic and ecological diversity to maintain adaptive potentialDecreased genetic inbreeding and less population isolationLocal endemic species historically functioning as one metapopulation but now fragmented into 13 known populations with genetically distinct groups in the eastern and western portions of range.Overall:By 2070, 44-67% reduction in representation.
Status quo:By 2070, 75% reduction in representation in the western group; 20% reduction in representation in the eastern group
Intermediate:By 2070, 75% reduction in representation in the western group; 40% reduction in representation in the eastern group
High:By 2070, 100% reduction in representation in the western group; 40% reduction in representation in the eastern group
