We quantified pine-forested habitat suitable for Red-cockaded Woodpecker Picoides borealis in the former historic range of the species to assess the potential for possible re-colonization.  We used a remotely-sensed image and geographic information systems (GIS) to create a land-use/land (LU/LC) binary cover map, from which we calculated the habitat suitability index (HSI) based on an estimated home range of 50ha.  A sensitivity analysis revealed the necessity for more data to make an accurate estimate, but our analysis of landscape metrics indicates more than 930ha of suitable habitat patches.  These patches are heavily fragmented and mostly located on private lands.  They can be assessed for understory and herbaceous vegetation and can be restored for possible re-establishment of approximately 18 groups/colonies of Red-cockaded Woodpeckers.
