The distribution, habitat, and current status of Oncorhynchus mykiss nelsoni (Evermann) were evaluated in the two main drainages of the western slope of the Sierra San Pedro Martir (Santo Domingo and San Rafael), Baja California, Mexico. The known localities of distribution (type locality and transplant sites), as well as other previously unsurveyed localities, were monitored during a period of seven years (January 1987 to March 1994) to document occurrence of the trout and to evaluate their habitat characteristics. The conservation status for this subspecies was determined as stable in the two main drainages, which range in altitude from 540 to 2030 m above sea level. Recommendations for future con- servation and management of the trout and their habitats are provided.
