Giraffids
Taxonomic position: The family Giraffidae belongs to the order Artiodactyla. While they are often viewed as wildlife, their feeding behavior in proximity to agricultural developments classifies them as significant herbivores that can impact local forestry and agroforestry systems.

Giraffids
Crops damaged: These animals primarily target trees and shrubs. In agricultural settings, they cause damage to commercial orchard seedlings, acacia plantations, and young canopy species. Their ability to reach high branches makes them unique pests that bypass traditional low-level protection methods.
Biology and life cycle: Giraffids are large mammals with long gestation periods and a social structure that supports wide-ranging foraging. Their physiology requires a constant intake of foliage, which compels them to visit high-quality vegetation patches regularly, leading to sustained pressure on preferred plant species.
Damage and harmfulness: The primary harm is the destruction of apical dominance in young trees. Browsing leads to stunted growth, distorted shapes, and reduced yields. Excessive foliage loss weakens the tree's immune system, making it more susceptible to secondary environmental stressors and opportunistic pathogens.
Control measures: Managing their impact involves physical and non-lethal deterrents to protect high-value crops. Key strategies include:
- Installation of tall, reinforced exclusion fencing.
- Deployment of sensory deterrents (noise or light).
- Application of taste-based repellents on tree bark and leaves.
- Implementation of landscape management to discourage entry into high-risk zones.
