KANSAS CITY, Mo. For the fourth year in a row, nature's natural lawn mowers are back in the Kansas City metro.

Effective immediately, over 40 goats can be found off the Heritage Riverfront Trail for the next month, grazing away at two acres worth of invasive, overgrown weeds. Consisting of babies and their mothers, the goats are provided by Kyle Alvis, the owner of Goats Gone Green and the Alvis Goat Ranch in La Tour, Missouri.

In a three-pronged partnership overseen by Port KC, Alvis Goat Ranch collaborated with CERES Tag to attach accelerometer-equipped solar panel tags to roughly 10 of the goats.

According to CERES Tag Kansas City sales lead Matthew Randerson, this means Alvis can monitor the herd's health from the comfort of his cellular devices.

"That's how we're able to understand all those different behaviors, grazing, resting, ruminating, drinking, and walking," Randerson said. "We can extrapolate how much they're eating, and based off that, we can extrapolate their farts or how much methane they're emitting."

"It has been very beneficial when you can get on your tablet and look and you can go to that individual animal," Alvis said.
