The storm drain is an outlet for a small river that regularly floods its banks in rainy weather. The drain is unfortunately dry at the moment, just a small trickle there - but when there is rain, the overflowing river water irrigates the wild grasses and other vegetation in this little area.
I'm happy to see that the environmental authorities pretty much let nature do its thing. For now, anyway.
Just now they'll think it a grand idea to slather the area with concrete for a carpark.
Nice to see and hear about. I've often thought it would be fun to let my lawn (which is pretty green but more weeds than grass) grow during May. I figure the guy who cuts it would kill me. He's already mown twice this spring.
I'll bet the pollinators love that place, along with small reptiles and the birds. =) Thank you for the follow. Very happy to reciprocate and thank you for participating in No Mow May.
