Ancient Forest Society

Did you know bark beetles threaten our forests, including giant sequoias? CAL FIRE’s Forest Health Research Grant Program supports @AFSociety in studying these pests. As part of the Giant Sequoia Lands Coalition, we're committed to protecting these majestic trees.

Watch #AncientForestSociety researchers in #SequoiaNationalPark make the first-ever climb🌲🧗‍♂️  of the #GeneralShermanTree (the world's largest tree) to check for bark beetles! 🐞✨ Incredible footage! Here's why: i.mtr.cool/wbdsqvwuyr 📹@NationalParkService #GiantSequoia

@PattyLievense that's for sure!

@AFSociety 🌳 Beats climbing Mount Everest

Honored to climb and inspect the General Sherman giant sequoia tree - the largest in the world - for potential beetle attack. We found some beetle activity but the tree appeared to be healthy and successfully fending off attack. Other sequoias are not so lucky.

@dudney_joan Thanks Joan!

@AFSociety You AFS people are the coolest!

Probably the first climb ever of the General Sherman Tree, the world's largest tree. Researchers with the @AFSociety ascended the 275-foot giant sequoia this week to look for bark beetles, the latest threat to sequoia trees: sfchronicle.com/climate/articl… Video from @NatlParkService

We're hiring a Program Associate to join our team working to study and protect ancient trees and forests. For more information and to apply: ancientforestsociety.org/careers

Just wow. Last night in Yosemite #CAwx

Gentle fire in the giant sequoias. Thank you YNP Fire and Arrowhead hot shots. #goodfire

This is an absolutely terrifying, and educational video. We have nearly a 20 foot base. Tree wells are DEEP AND DANGEROUS! This rescuer was textbook in his procedure. Saved that boarder's life. Hats off. youtube.com/watch?v=wQ8Kgb…

We had a great visit to Giant Forest to download treetop sapflow and weather data, which we are using to learn how giant sequoia trees respond to fire, drought, and beetle attack. The solid snowpack so far this winter is a welcome relief for these thirsty trees.

Some pics from a recent trip collecting giant sequoia cones to preserve their genetic heritage and assist with reforestation efforts in high-severity burn areas. #conehunters #Sequoia #kingscanyonnationalpark #CAfire

We're excited to share our new logo #AncientForest #BigTrees

Fog has long been recognized as an important water source for coast redwoods trees, which have the ability to absorb water through their leaves. We've recently discovered that giant sequoias also have this ability, such as during periods when low clouds roll through the canopy.
