Scientific Name: Gladiolus pole-evansii
Species Authority: Verdoorn

Assessment Information [top]

Red List Category & Criteria: Vulnerable D2 ver 3.1
Year Published: 2003
Date Assessed: 2003-04-30
Assessor/s: Pfab, M.F. (Gauteng Nature Conservation) & Victor, J. (National Botanical Institute)
Reviewer/s: Golding, J. & Hilton-Taylor, C. (Southern African Plant Red List Authority)
Justification:
Gladiolus pole-evansii has a very restricted distribution with an area of occupancy of < 2 km², and is known from only two localities. The localities are in relatively remote rural areas where there are no significant threats at present. However, due to the very restricted distribution of this species it has been listed as Vulnerable under criterion D2, as it could easily be wiped out should, for example, a granite mining operation start in the future. The RAMAS® Red List software package was used to make this assessment.
History:
2000 Vulnerable

Geographic Range [top]

Range Description: Occurs in the Gauteng and Mpumalanga Provinces of South Africa from Bronkhorstspruit between Verena and Groblersdal. Has a very restricted distribution being known from only two localities. The plants are locally common, but do not occur outside of this area. Collections from Swaziland have allegedaly been named as this species, but these are probably misidentifications, and are more likely to be Gladiolus sericeovillous Hook.f.
