Help Us Restore Sand Hill Farm

Yes, dramatic progress has been made at Sand Hill Farm, but there is still much work to be done.  While the hills look green and the cover crop is holding the sediment, there is still trash and plastic to be removed ... and then there is the restoration planting too. 

Your contribution to ESF funds the amazing transformation of this key property that rises from the slough.

Newborn Otter Pup on OtterCam!

On December 28, 2016 near the end of the day we focused our OtterCam on a lone otter. Moments later, to our surprise a pup was born!

Our staff quickly scrambled into action and captured mom's first moments with her tiny pup on our first Facebook Live event. You can see the whole video on our Facebook Page.

Visit our OtterCam today. You never know what will happen out at the Slough!
