Precision, accuracy, and costs of survey methods for giraffe Giraffa camelopardalis

Giraffes Giraffa camelopardalis are megafaunal browsers and keystone species in African savanna ecosystems. Range-wide population declines are suspected, but robust data are lacking. Tanzania holds the largest population of giraffe of any range state, and aerial surveys constitute most of Tanzania’s giraffe population monitoring data, but their accuracy has not yet been assessed. An IUCN status assessment for giraffe is currently underway, and calibrating aerial surveys with ground-based surveys can quantify accuracy of the aerial surveys to ensure more reliable

Observations on field immobilization of free-ranging giraffe (Giraffa camelopardalis) using carfentanil and xylazine

This report describes immobilization techniques used in free-living giraffes for studies of reproductive physiology and ecology. The ecological studies involved minor manipulation for blood sampling and radio-collaring, and a quiet sedated giraffe in lateral recumbency was required. The reproductive studies required anesthesia for semen collection by electroejaculation.

Seasonal chemical composition of the diet of Transvaal lowveld giraffe

Rumen contents of giraffe (Giraffa camelopardalis) were collected over a 1-year period in the eastern Transvaal lowveld and crude protein, ether extract (fat), crude fibre, ash and gross energy content were determined. Variations in crude protein, ash and gross energy content of the diet could be related to changes in the composition of the diet of the giraffe and to seasonal phonological changes of the vegetation. There was no evident correlation for crude fibre or fat, but this could have
