Learn about sugar pines
Sugar pines are the world’s largest species of pine and have the longest cones, but they are dying from white pine blister rust, a non-native, invasive fungus.
Once comprising 25% of Lake Tahoe’s forests, sugar pines now make up less than 5% of the forest composition. We find trees that are resistant to the fungus, then we collect their cones and plant their progeny.
