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