When visiting Andis Wines, do you notice the white boxes sitting on poles positioned throughout the vineyards? Part of our sustainability program involves using birds of prey to control the rodent population.
As you walk through the vineyards, you will notice small holes in the ground, typically caused by gophers and voles. Voles will eat roots and bark and can be harmful to grape vines, and controlling their populating is critical as a pair can produce 100 baby voles in a year.
As you view the Andis Estate Vineyard, you will see owl boxes, those white boxes perched on tall poles. Owls will find these boxes, create a nest, usually in winter and early spring, and have their young. All four boxes on the property have been used. A family of owls can hunt as much as 3,000 moles a year. By May, the baby owls are gone, and the boxes remain empty until the following year. Eating so many voles, gophers, and even rabbits create quite a mess with bones stacking up, so we must clean the boxes out after harvest in preparation for the next season.
