In the coastal part of southwestern Madagascar, herbaceous forage is scarce during the dry season. Despite this, transhumant herds of cattle and, to a lesser extent, small ruminants, from the even drier and politically insecure Mahafaly plateau populate the coastal plains during this period. Livestock keepers partly compensated the lack of herbaceous forage by harvesting branches of the succulent evergreen shrub Euphorbia stenoclada Baill. to feed the herds. In consequence, this endemic and protected (CITES Appendix II) plant is under very strong pressure.
