Signs of spring! Frogs calling.

 Spring is coming to the Northwest Branch Park. Video taken in the  evening does not show the Wood frogs, but you can hear them!   And on 3/15/19, a solid showing of wood frogs: 3 egg  masses. Sounds like there will be more tomorrow.  This is in a yard pond near the  confluence of Bel Pre Creek and the NW Branch. 



In just 7 minutes 4 seconds, here's the Northwest Branch and what we do.  Check it out.  Then join us.  The more people are engaged, the more we all can accomplish!  Special thanks to John Sullivan for creating this video!

Stream Monitoring
