Cabrera's vole

Cabrera's vole (Microtus cabrerae) is a distinct rodent species belonging to the family Cricetidae, order Rodentia. While recognized for its specific habitat requirements as an Iberian endemic, in an agricultural context, it acts as a pest capable of significantly impacting forage crops and cereals grown in humid or marshy areas where its natural populations expand into cultivated land.

The diet of Cabrera's vole consists primarily of grasses, cereals, and legumes. The economic damage caused by this rodent is significant, as it consumes both the green foliage and the roots of young plants. This feeding activity results in sparse crop stands, reduction in forage quality, and significant biomass loss, which directly affects the profitability of agricultural enterprises.

Regarding its biology and lifecycle, Microtus cabrerae is characterized by high activity levels in damp environments. Unlike some other vole species, it maintains a year-round presence, with its reproductive rate strictly correlated to the availability of lush, moisture-rich vegetation. Their ability to form dense colonies makes them a resilient pest that can quickly colonize adjacent agricultural fields.

The damage caused by the vole is characterized by patches of decimated crops, underground tunneling that disrupts soil structure, and damage to the root systems. This voles' pest potential is enhanced by their ability to thrive in undisturbed margins of fields, from where they migrate to destroy crops, often leading to secondary weed infestations due to soil disturbance and plant mortality.

Effective management and protection strategies include:

• Maintaining field margins and preventing excessive weed growth near water sources.
• Utilizing tillage operations to disrupt burrow networks and breeding habitats.
• Deploying integrated pest management (IPM) practices, including the use of targeted rodenticides.
• Encouraging natural predators such as raptors through the installation of perch poles in fields.
