Every year, our property management company performs a controlled (prescribed) burn of our prairie grass areas. I filmed this burn today at Glynn Village in Waukee, Iowa. The burn is done to help promote growth of native grasses and wildflowers. The prairie acts as a natural stormwater filtration and retention system. I shot this aerial video with my DJI Phantom 3 Pro in 4K.
Here is a little video filmed from the ground in our neighborhood from about six years ago.
