Quick Answer
Ground squirrels are considered agricultural pests because they cause significant damage to crops, primarily potatoes, alfalfa, and other root vegetables, through their burrowing activities and feeding habits, resulting in substantial economic losses for farmers.
Ground Squirrel Burrowing Habits
Ground squirrels are notorious for their extensive burrowing activities, which can lead to significant damage to crops. They dig complex networks of tunnels and burrows, often close to agricultural fields, causing soil compaction and erosion. According to a study in California, a single ground squirrel can excavate up to 700 pounds of soil in a single year, leading to reduced soil quality and increased risk of soil-borne diseases.
Ground Squirrel Feeding Habits
Ground squirrels are herbivores and feed on a wide range of crops, including potatoes, alfalfa, and other root vegetables. They can cause significant damage to these crops by eating them, as well as by damaging the plants through their burrowing activities. In California, ground squirrels are known to cause up to 30% losses in potato yields, resulting in substantial economic losses for farmers.
Ground Squirrel Control Methods
Effective control methods for ground squirrels include using repellents, trapping, and shooting. Repellents can be used to deter ground squirrels from entering agricultural fields, while trapping and shooting can be used to control populations. In California, the California Department of Fish and Wildlife recommends using a combination of these methods to control ground squirrel populations, as well as implementing good agricultural practices, such as crop rotation and soil conservation, to reduce the impact of ground squirrel damage.
