Justification
The population of Encephalartos longifolius has declined by about 20% in the past three generations, thus it approaches the thresholds for Vulnerable under criterion A2. It would also qualify as Vulnerable under criterion B1ab(v) if there were fewer localities. The species is therefore listed as Near Threatened.
Distribution
Endemism
South African endemic
Provincial distribution
Eastern Cape
Range
This species is widely distributed in the Eastern Cape from west of Joubertina in the Kouga mountains, along the Suuranys mountains, in the Baviaans Kloof, the Elandsberge, the Zuurberge and then on to near Grahamstown. Large subpopulations occur in the Kouga Mountains, Baviaanskloof, Groot Winterhoek mountains, and the Zuurberg. It has been recorded from 200 up to 700 m asl.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Algoa Sandstone Fynbos, Kouga Grassy Sandstone Fynbos, Suurberg Shale Fynbos, Vanstadens Forest Thicket, Sundays Mesic Thicket
Description
It occurs in a variety of habitats with large differences in soil and climate. In some areas west of Port Elizabeth plants grow in acid sands with fynbos vegetation whereas in the Zuurberg they occur in grasslands. Near Kirkwood and in the Paardepoort plants grow amongst succulent thicket. They are also found in dense scleromorphic shrubland on steep rocky slopes.
Threats
The only real threat to this species is over-collection due to poaching of plants from the wild.
