SIGNIFICANCE TEST ONE




The regional total area is 99099.67

The regional extent of core remnant is 26875.45

The regional extent of core remnant is 27.12 percent

This level of regional fragmentation sets a local impact threshold of: 5.0 percent




The table below lists the local impact thresholds for categories of regional core remnant extent:




REGIONAL CORE CATEGORY                 LOCAL IMPACT THRESHOLD

< 10                  2.0

10 - 30               5.0

30 - 50               10.0

50 - 70               20.0

70 - 90               30.0

>90                   50.0




Area of core at the local scale (pre impact): 2386.69

Area of core at the local scale (post impact): 2386.57
