Prairie dogs are the rodents which make burrows. These prairie dogs live that burrows in large colonies in the grasslands. Prairie dogs are regarded as a “keystone” species because their habitats provide benefits to lot of other species. A number of species such as tiger salamander use their burrows as their homes. Most importantly prairie dogs aerate and fertilize the soil as their burrows act as conduits for rain water to seep into the ground, thereby promoting the growth of grass. This promote greater diversity of plants in that region.
D) Their tunnels act as conduits for rain water to seep into the ground, thereby promoting the growth of grass.
The tunnels that prairie dogs dig act as conduits for rain water to seep into the ground, thereby promoting the growth of grass. Because prairie dogs play the role of ecosystem engineers, they would be a keystone species in the grassland ecosystem.
