St. Croix Valley

St. Croix Chapter is located in an area that at one time included large dry prairies. Today there are small oak savanna remnants that still contain some uncommon plants associated with those historic prairies. Our chapter works on a few of these, visits others to appreciate what is left, and educates folks on fire-dependent ecosystems. 

The St. Croix chapter covers Pierce, Polk and St. Croix Counties in Wisconsin. We invite you to join us!

Is there an Insect Apocalypse in Wisconsin?

Date: Tuesday, January 21

Time:  6:30 pm

Location:  River Falls Public Library.

Our speaker, Kevyn Juneau, UW-River Falls professor, describes the results of his team's insect diversity survey of the Kinnickinnic watershed in Summer 2019. He also compares the results with what is happening around the world.


Winter work parties

Get outside and help restore a native oak savanna!  We typically cut buckthorn and other invasive woody plants to clear the canopy over native plants.

Dress for the weather and bring some drinking water.  We will provide hot dogs for lunch and beverages.  (Feel free to bring your own lunch if hot dogs are not your thing.)

Date:  Saturday, January 25, 2020

Time:  10am to 2pm.  Come for one, two, or three hours -- whatever time you can volunteer is very welcome!

Location:  Alexander oak savanna


From River Falls, take highway 65 south (35 turns into 65) toward Ellsworth.  Park at the Town Hall.  It is on the left side, just past 770th Avenue. We will walk to the site from there.  

The site is on the right side (east).  If you have 4-wheel drive, you can drive on the farm field.

Chapter meeting -- February 8



Live near the Rush River?

In the 170 years since government surveyors first crossed the lower Rush River in 1849, the landscape is threatened with loss of water quality, invasive species and deer overpopulation, fragmentation and decline of hardwood forests, the disappearance of prairies, and a loss of biodiversity. Now, in 2019, the fate of the Rush and other rivers hangs in the balance.

To preserve what is left, current landowners, as stewards of the land must understand the threats and what can be done to combat them. 

TPE member and Rush River resident Carl Nelson is forming an exploratory group of three to five individuals to discuss and reach a consensus on priorities and a plan of action. 

You can read his report here.  Contact Carl if you want to help (cnelso96 at
