Bakersfield saltbush, Bakersfield smallscale, Tulare saltbush, Tulare orach

 

 

Taxonomy & Nomenclature

 

 

Conservation Status

Extinct (Rejmánek, 2018; Smith, 2018; Knapp et al., 2020, 2021; Albani Rocchetti et al., 2022); erroneously considered rediscovered by (Humphreys et al., 2019:SD1) (see Knapp et al., 2020)

Last record: 1891 (Knapp et al., 2021); 1934 (Smith, 2018); 1991 (Rejmánek, 2018 [error for 1891?])

 

This species has been identified as one of the 50 best candidates for de-extinction, ranking 49/50 (Albani Rocchetti et al., 2022).

 

"Besides dramatic reduction of suitable habitats, hybridization with Atriplex serenana Nelson ex Abrams (a native species better adapted to dry conditions) resulted in swamping of the A. tularensis gene pool (Freas & Murphy, 1988, 1991; Rhymer & Simberloff, 1996; R. Tollifson, personal communication, March 1, 2017)."
