Scientific Name | Gladiolus insolens Goldblatt & J.C.Manning |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2015/05/04 |
Assessor(s) | N.A. Helme, P. Goldblatt, D. Raimondo & D. van der Colff |
Justification | A rare, localized habitat specialist (EOO and AOO less than 5.8 km²), only known from two locations where habitat loss to damming of streams was a past and remains a potential future threat. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Piketberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Piketberg Sandstone Fynbos |
Description | Seeps and streams that remain wet until December, always in rocky sites on higher slopes. |
Threats |
| The habitat of this species is vulnerable to flooding as a consequence of damming of mountain streams. A nearby stream was dammed some years ago, destroying about three hectares of streamside habitat (N.A. Helme pers. obs.). Further habitat loss to dam construction remains a potential threat. |
Population |
Population trend | Stable |
