Celebrate Earth Day: Adopt an Oak!

Adobt an oak

This is your chance to be part of creating an oak woodland.  You can adopt an oak and watch it grow too.  When you “adopt” your tree you will receive a Google Earth link that shows the tree assigned to you.  As the years go by, you can view the progress of your adopted tree with every Google Earth image update. Imagine the changes you might see as the oak sapling becomes a mighty oak and habitat for wildlife.  You’ll even receive your “Virtual Oak Adoption Certificate.”  And you will know your oak is protected on the conserved lands of the Elkhorn Slough Foundation.

We want these little oaks grow into sturdy trees so that future generations can admire the ancient oaks of our watershed.  Throughout their lives, these trees will provide habitat for birds and shelter for a variety of wildlife. 

What a great way to Celebrate Earth Day!

Adopt an Oak Today!


Ron Eby On Volunteering...

Elkhorn Slough Reserve and Foundation depend on the generosity of volunteers to help accomplish our mission. 

At a recent event updating volunteers on the science being conducted at the slough, volunteer Ron Eby inspired the group as he talked about the joy of volunteering at Elkhorn Slough and we caught it on video. 

If you're interested in volunteering, join us for a special work day on June 4th.
We will be collecting seed for future restoration projects.

Teachers, Get Muddy in an Estuary

TOTE postcard

This summer the Elkhorn Slough Reserve will offer a new workshop for middle school and high school teachers. 

The Teachers on the Estuary (TOTE) is a two day workshop that introduces teachers to the research on the reserve through hands on data collection and monitoring with Reserve scientists.  It is an opportunity to get in the mud and experience the science first hand.  Lessons for the classroom will be explored and developed, and training on NOAA data access and use will be provided.

Let's #getmuddy
