Species | Status | Ecological characteristics | Potential impacts of fire regimes |
---|---|---|---|
Brunia trigyna (Schltr.) Class.-Bockh. & E.G.H. Oliv. | Critically endangered5 | Slow-growing large woody shrub; subpopulations are extremely fragmented5 | Sensitive to frequent fires (grows in sites protected from fire)5 |
Watsonia pondoensis Goldblatt | Endangered5 | Geophyte | Sensitive to frequent fire and overgrazing5 |
Leucospermum innovans Rourke | Endangered5 | Resprouting shrub; myrmecochorous, thus requires high fire intensities to stimulate seed germination1 | Too-frequent fire may result in inadequate seed production and poor recruitment5 |
Kniphofia drepanophylla Baker | Vulnerable5 | Geophyte | Sensitive to frequent fires associated with heavy grazing and trampling5 |
Leucadendron spissifolium (Salisb. ex Knight) I. Williams ssp. oribinum | Vulnerable5 | Slow-growing woody shrub; dioecious; serotinous; resprouter1 | Too-frequent fire may result in inadequate seed production and poor recruitment5 |
Leucadendron spissifolium ssp. natalense (Thode & Gilg) I. Williams | Near threatened5 | Slow-growing woody shrub; dioecious; serotinous; resprouter1 | Too-frequent fire may result in inadequate seed production and poor recruitment5 |
Hyperolius poweri Loveridge | Not assessed (due to recent taxonomic change)8 | Frog associated with emergent vegetation on the margins of swamps8 | Sensitive to habitat loss as a result of regular fire (loss of cover)3 |
Breviceps bagginsi Minter | Endangered6 | Frog favoring habitat associated with grassland8,4 | Sensitive to habitat loss as a result of regular fire (loss of cover)3 |
Bradypodion caffer Boettger | Endangered8 | Chameleon represents a grassland ecomorph of B. caffer; only occurs in natural grassland8 | Require long fire free intervals to facilitate dispersal8 |
Insecta (73 species found are endemic to South Africa, and at least 18 species endemic to Mkambati) | 21 species not yet assessed by IUCN and thus listed as endangered2 | Burning is known to influence invertebrate communities, but further research is required in this diverse group2 | Burning positively influences species richness; highest numbers of endemic species were found in unburned vegetation2,7 |
