There have been millions of dollars of timber, jobs, along with other resources riding on figuring out the limits of its variety. As a result, it was imperative to ascertain if there have been 1? species or subspecies to become regarded as for protection beneath the U.S. Endangered Species Act. In two studies (B) making use of 3 markers (mtDNA, microsatellites, and RAPDs), we discovered agreement for 3 subspecies: Northern (S. o. caurina), California (S. o. occidentalis), and Mexican (S. o. lucida) with evidence for subspecies hybridization exactly where taxa met geographically (Haig et al. 2001, 2004a,b).

This became a larger concern when we discovered proof that Northern Spotted Owls were hybridizing with Barred Owls (Strix varia) that had been rapidly expanding their variety in to the Pacific Northwest. Not recognizing how in depth this hybridization might be, we created mtDNA, microsatellite, and AFLP markers to differentiate these taxa for use by law enforcement laboratories (Haig et al. 2004a,b; Funk et al. 2006, 2008a).

A little-used clause in the ESA (section four(e)) supplied a potential option (Haig and Allendorf 2006). This `similarity of appearance' clause provides protection for species that are not listed but closely resemble an ESA-listed species.
