We are currently updating our information about all the programmes in which students can participate. In the meantime below are some of the current projects and a selection from the 114 peer-reviewed publications illustrating the wealth of research that has been based on or included Lajuma.

Behavioural ecology of Crested Guinea-fowl (Guttera edouardi).

Targeting a well-habituated population of this poorly-researched forest specialist, this long-term project investigates their biology and ecology including diet, ranging and social behaviour. A behavioural catalogue has been generated and a flock are to be captured and ringed to enable individual identification.

Forest biodiversity conservation.

The focus is on various aspects of forest biodiversity, ecology and threats within the Lajuma forests and subsequently across forests in the Soutpansberg, many in the east being highly degraded through anthropogenic disturbances. Initial work on the relatively pristine forests of Lajuma provides a baseline for comparison. Mammal diversity and densities, how these change according to forest structure and the role they play in seed dispersal and thus forest maintenance are key research areas and results inform regional conservation planning.

The project involves collecting data on tracks, droppings, feeding signs, actual sightings and vocalisations of mammals along transects, monitored directly and also with cameras. Mammal seed dispersal involves transect monitoring of fruiting trees and identification, quantification and determination of viability (germination experiments) of seeds collected from droppings, the aim being to compare the role different mammal species play in forest plant seed dispersal.

Samango monkey behaviour and ecology

The samango monkey (Cercopithecus albogularis) is South Africa's only exclusively forest dwelling primate and represents the southernmost extent of the range of arboreal guenons in Africa. The local subspecies is listed as Endangered in the Red Data Book of the Mammals of South Africa and considered a rare species.

Camera trap monitoring

A 40 camera grid is in operation monitoring mammal diversity and density with five years of data available for analysis by researchers.
