Musk deer

The musk deer (genus Moschus) is a small deer-like mammal belonging to the family Moschidae of the order Artiodactyla. Unlike true deer, musk deer lack antlers, but males possess elongated tusks and a gland that produces musk. While these animals primarily inhabit mountain forests, they can cause significant damage to forestry nurseries and young agricultural plantings located in fringe zones.

This species primarily targets young coniferous trees, nursery seedlings, and certain types of shrubs. During winter, when natural food sources are scarce, musk deer may feed on the shoots of various young plants near forest edges. The damage is most acute in foothill regions where agroecosystems intersect with natural wild habitats.

The biology of the musk deer is characterized by a solitary and secretive lifestyle, supported by remarkable agility and jumping ability. Breeding occurs once a year during the spring. They are sedentary animals that occupy specific home ranges, which allows for local monitoring of their activity. Winter food shortages are the primary driver behind their movement into cultivated areas to browse on vegetation.

Damage symptoms include the browsing of terminal shoots and stripping of bark from young saplings, which leads to stunted growth, structural deformities, and potential mortality of the plants. Beyond the direct loss of biomass, damaged bark serves as an entry point for various fungal pathogens and wood-boring insects, further compromising the vitality of the forestry or nursery stock.

To protect crops from musk deer, a combination of exclusion and deterrent strategies is recommended:

• Installation of high-tensile wire or mesh fencing around nurseries and young plantations.
• Application of chemical repellents on tree trunks and shoots to deter feeding.
• Implementation of visual and acoustic scare devices to discourage animal entry.
• Management of surrounding vegetation to reduce cover and shelter near high-value crop areas.
