2020 FLOAT SURVEYS UPDATE:

After much deliberation, JHWF and our partner Jackson Hole Vintage Adventures have decided to not undertake Nature Mapping Jackson Hole’s Snake River Float Surveys this year due to the Covid-19 pandemic. Unfortunately, we cannot guarantee proper social distancing while on the river and since this project involves the participation of volunteers and staff from multiple households, our primary concern is not being able to provide a safe environment in which to work. Additional considerations due to time and costs have also played a factor in our decision-making. We hope to hit the water again next year. In the meantime, we will be using the months ahead to evaluate the project, work through years of data collection, and share the results.

We appreciate your patience and understanding surrounding this challenging time. Please feel free to reach out with any questions. – JHWF Staff

About our Snake River Floats Project:

The Snake River Floats Project is designed to gain a better idea of what species of mammals, birds and amphibians use the section of river between Wilson Bridge and South Park. In this section, the river flows mostly through private land where wildlife professionals do not conduct a systematic census.

The Snake River Float project helps to provide a more complete picture of the species that use the river corridor between Wilson Bridge and South Park. It has recorded the locations of nests of osprey, bald eagle, and great blue heron, along with ducks and shorebird nesting areas. This project has recorded thousands of individual birds. Mammals observed range from least chipmunk to moose.

The float also provides a wonderful opportunity to enjoy AJ DeRosa’s wooden boat adventures. AJ’s Jackson Hole Vintage Adventures generously offers this opportunity in support of our citizen science program. Please note: Float trips are canceled for the 2020 season.

Snake River Float Trip Details

When

Floats take place every Sunday morning from May through September and include about 3 hours on the river. Float participants typically meet at the Stilson Ranch parking lot at 7 am, but those details will be confirmed by the trip leader. Jackson Hole Wildlife Foundation ensures that there is at least one trained Nature Mapper on every trip, and has advanced and expert birders on each trip.

Who

Float trips for this section of the river are offered courtesy of AJ DeRosa’s Wooden Boat Tours. Special thanks to AJ and his boatmen! A $30 per person fee for the trips for the shuttle is suggested and you may elect to offer a tip to the guide(s).
