The Critically Endangered Caledon Conebush

25 Aug 2021

The critically endangered Caledon conebush, Leucadendron salteri subsp. elimense, occurs in an area of less than 9 km², in four small, severely fragmented subpopulations. It continues to decline due to alien plant invasion, ongoing habitat loss to agriculture, and wildflower harvesting. Most subpopulations are on isolated fragments among crop fields in the Bot River Valley, Hemel-en-Aarde Valley and Shaw’s Pass, and only one is formally conserved, the one found in Craigantlet Nature Reserve situated near the town of Bot River.

Leucadendron elimense subsp. salteri. elimense is a shrub growing up to 1.5m and is sparsely branched. It is a dioecious plant, meaning the female and male flowers are on separate plants. It flowers between August and September and is pollinated by insects. The parent plants are killed by fire, but the seeds are stimulated by fire to germinate.

Estuaries Between Drought and Flood

The Western Cape has just emerged from, in some areas, up to an eight-year drought cycle. This is linked to bigger global oceanic and climatic conditions. The poor rainfall resulted in low freshwater flows in the rivers and very little freshwater reaching the estuaries which are the receiving environment of the freshwater flows left in the rivers after abstraction and use in the catchment.
