The Real Beaver Science Behind Pixar’s "Hoppers" Pixar’s Hoppers is grounded in real beaver science. Discover how beavers reshape rivers, protect ecosystems from fire and drought, and inspired the film’s accuracy.

Oh no! Lemme try again!

If you want to learn more about the science behind the movie, you can read about it here: www.laughingplace.com/.../pixar-ho...

Hoppers is a stellar example of telling a hilarious story while also clearly communicating real environmental science and beaver ecology to the general public.

...the coolest of which was taking Pixar's art team into the field for a week and showing them how incredible, beautiful, and chaotic beaver ponds are in real life. I'd visited these sites many times before for research, but never with a team of exceptionally talented artists in tow.

What started with a zoom talk for a handful of Pixar people ended up with a character named after me (shoutout to Dr. Samantha E. Fairfax) and walking the red carpet at the world premiere!

My role as a science consultant and "beaver expert" involved a variety of things...

After about 5 years (!) of keeping secrets, I am so excited that Disney Pixar's Hoppers is finally coming out on March 6th!

Back in 2021, Pixar emailed me asking if I could give a talk about my research to their employees. Then another talk. And another.

I’d recommend switching to a black flexible pipe (rather than rigid white pipes) and submerging the ends in the downstream creek! The black color helps with heat retention and keeping the ends in flowing water limits ice build up.

Beavers can boost water storage, wildlife habitat, and carbon capture. A new mapping tool helps identify sites where beaver reintroduction programs could deliver ecological benefits.

A great example of compromising with beavers!

Beavs are stubborn little engineers and don’t particularly care to pull permits or share their design plans with us. Luckily, humans are clever engineers too and can share (not take!) control of the water with a bit of fencing and some pipes!

As nature’s β€˜ecosystem engineers,’ beavers could help fight effects of climate change Beaver dams reduce flooding, create wetlands that boost biodiversity and can even slow wildfires. But bringing back beavers would require a shift in public attitude β€” and finding ways for humans and beavers to coexist.

In Minnesota, beavers have long been considered a nuisance, thanks to their ability to gnaw trees and construct dams that sometimes clog culverts, raise lake levels or flood roads. But among scientists, there’s a growing recognition that these engineers bring a host of environmental benefits.

How beavers could help fight wildfires | CBC News New research out of the western U.S. suggests dams and ponds built by beavers can slow floods, store water and even create green firebreaks in wildfire-prone landscapes.

Beavers are admittedly chaotic and work their ecosystem magic in sometimes mysterious ways.

But we’re trying our best to understand them & work together to fight wildfires!

Check out this article covering Luwen’s recent paper and some of my previous fire + beavs work!

A four panel figure from the paper showing a dam made with trash, a dam made with invasive blackberry, a cut burnt pine tree, and a dam made of mud and grass.

The solution? Use field work and community observations to make note of what your local beavers are *actually* building with, and then update the models to reflect that.

In a new peer-reviewed perspective article led by my postdoc Jessie Moravek and with contributions from many members of the Fairfax lab, we summarized existing popular beaver occupancy models and highlight how beavers like to "break the rules," and then in turn, the models.

Can you predict where a beaver will build a dam? Or how many dams they will build?

There are many models for beaver habitat availability & dam building potential. One thing they all have in common? They need to be calibrated with local knowledge of place-based beaver behavioral adaptations!
