Giraffe

The giraffe (Giraffa camelopardalis) is an artiodactyl mammal within the Giraffidae family. From an agronomic perspective, it acts as a significant herbivorous pest, particularly within agroforestry systems where it exerts strong pressure on woody plant species through selective browsing and defoliation.

The giraffe's diet consists primarily of leaves and young shoots from trees and shrubs. They are particularly known for their impact on Acacia spp. and other leguminous trees. By utilizing their specialized anatomy, giraffes can forage at canopy levels inaccessible to smaller herbivores, making them a unique threat to the crown development of commercial forest stands.

Regarding biological behavior, giraffes exhibit high foraging efficiency throughout their active cycle. Their feeding patterns are highly selective, targeting nutrient-dense new growth. This intensive browsing behavior, especially during the dry season, can significantly alter the physiological state of the plants and disrupt their annual growth cycles.

The damage caused by giraffes includes physical removal of vegetative tissue, leading to stunted growth, distorted crown architecture, and decreased carbon sequestration capacity. In extreme cases, repeated heavy browsing leads to the dieback of saplings, which prevents natural regeneration and limits the establishment of new tree plantations in their home range.

Control measures for minimizing giraffe damage in agricultural areas focus on spatial exclusion and habitat management. Key strategies include:

• Erection of high-tensile wire fencing and physical barriers.
• Installation of individual tree guards to protect terminal buds.
• Selection of browse-resistant plant varieties for new plantations.
• Strategic placement of alternative forage resources to divert animals away from sensitive zones.
