Look up Valley Creek Rd. at Bielenberg Dr in Woodbury in Google maps to see what we're looking at! |
Things may seem a little hazy in this mystery of the month photo.
The burning question – what is happening here, and why?
Can you guess what staff member(s) were caught in this Google maps image?
You’re getting warmer…
Recently a staff member was using an on-line map service to create directions to an event, when she noticed this interesting phenomenon: the aerial image of the Valley Creek Road Infiltration Basin was taken while our contractor was conducting a prescribed burn of the 7 acre site.
We aren’t just blowing smoke – burning is an excellent way to give a prairie patch a jump start on spring. Burning a prairie removes the thatch layer and darkens the soil. This gives warm-season prairie plants a boost early in their growth cycle. Burning has other benefits as well – reduction of weeds is a prime example. Seeds of annual weeds are often damaged or destroyed, and many biennial and perennial cool-season weeds are set back by an early toasting. Nutrients locked up in dead plant material are also released by a burn.
Burning is done in the early spring (which is when this photo was taken) or in the late fall.
The Natural Resources staff at RWMWD attempts to schedule burns every 2-3 years in our restored sites. In the growing season following a prescribed burn these prairies amply demonstrate their appreciation, producing an abundance of colorful blooms and lush grasses.
