General vigor of population: fair; probably reproducing, but scarcity 

 of potential cavity trees may be limiting. Some good quality foraging 

 habitat is present on both natural areas.

 extensive cutting of younger stands would reduce suitability of habitat. 

 The continued occurrence of fire is needed to control shrub growth and 

 maintain structure of vegetation preferred by this species.
