Sugar pines are the world’s largest species of pine and have the longest cones.

Once comprising 25% of Lake Tahoe’s forests, they are dying from white pine blister rust, a non-native, invasive fungus.

Sugar pines now make up less than 5% of our forests.

We find trees that can resist the fungus, collect their cones, and plant their seedlings.

How we help Tahoe’s forests

  • Person planting a small pine tree in the soil.

    Blister rust resistant tree identification and planting

    We find trees resistant to the blister rust fungus and plant them in our forests, building a generation of resilient white pines.

  • Mountain landscape with a hillside covered in burnt trees and rocks, with a green forest in the background under a cloudy sky.

    Burn scar restoration

    After a fire, we help encourage healthy diversity of trees by replanting within burn scars in the Tahoe area.

  • People snowshoeing in a wooded, snowy area with tall trees; the photo is taken from behind a bark-covered tree trunk.

    Educational Hikes

    We lead hiking and snowshoeing trips through Tahoe’s forests to educate the public about the natural beauty and value of our forests.

The Sugar Pine Foundation is honored to help steward the ancestral homelands of the Washoe and Nisenan people.

These tribes still actively care for the forests, waters and natural resources of the greater Lake Tahoe region to this day. We are grateful to partner with our Washoe friends on many events.
