Concerned citizens, Washington Co. Parks, Washington Conservation District, MNDNR, HerpMapper, UMN, and MN Herpetological Society joined forces to protect turtles, including the state threatened Blanding's Turtles.

Here are some photos from an experimental turtle underpass project. The project is using ACO barricades and silt fencing to funnel turtles (and other critters) to the underpass.

What is the long term plan for replacing the the silt fence? I don't imagine they plan on having that up permanently.

Don,

We are still discussing the long-term details. The silt fence has several benefits over the ACO brand barrier. To name a few...

1) Cheap.
2) Very easy to install (highway dept has a special machine).
3) Can be removed during the winter if necessary (to avoid impacting snowmobile traffic.

The ACO barrier does "look" nicer, but it was a pain in the a#$ to install. It is also somewhat "cheap" seeming, and it is tough to create an impenetrable barrier for small things like snakes, frogs, salamanders, etc. (lots of gaps because of uneven ground and the rigidness of the product).

This project is very experimental, and we plan to continue to adapt / modify as we continue to observe its efficacy.

-Chris
