Today, Redwoods and Climate Change Initiative scientist, Allyson Carroll, shares her perspective on how she decodes the history of redwoods from tree rings. Imagine finishing a massive puzzle, one involving nearly half a million pieces and taking years to complete… it feels …
I stumbled across a sea of sword fern that is showing signs of drought during my annual field campaign last month. Along the Damnation Creek Trail at Del Norte Redwoods State Park, the typically green carpet of sword fern was undeniably …
This week, I celebrated 10 years of coast redwood forest research and had the pleasure of climbing into an old redwood at the Grove of Old Trees in Sonoma County. This little-known forest is where I learned to climb …
Climbers took to the coast redwood treetops at Muir Woods National Monument for the first time this spring. Their canopy exploration was part of BioBlitz 2014, a massive effort to learn about and celebrate the biodiversity of Golden Gate National Recreation. …
All the elements combine to shape the trees we walk among every day. We see the result in glorious towering and sometimes twisting trees that curve and arc above us. Deep within the trunk and branches of every tree, wooded …
There are certain animals in the redwood forest that easily call attention to themselves. The banana slug is bright yellow, the Pacific giant salamander barks, the spotted owl hoots, and the yellow-spotted centipede has distinctive yellow spots on the sides …
With the heatwave we are experiencing in California this week, it’s hard to not think about drought. All this dry weather, combined with below-average rainfall, must pose serious challenges for local trees. What’s amazing to me, is that the fantastically …
It’s National Environmental Education Week! This week is a celebration of environmental education and a special time to inspire learning and stewardship among students. I can’t say enough about how important outdoor education is to complete the circle of land …
Lichens contribute such beautiful colors to our redwood forests, growing elegantly on trees, fallen logs, and rocks. Each lichen you see is actually a symbiotic partnership — algae or cyanobacteria wrapped up in a fungal package. Thanks to canopy biologists Rikke Reese Næsborg, Cameron Williams, Marie Antoine, and …
This time last week, our intrepid research partners were ascending up into the tall trees of Cathedral Grove at Muir Woods National Monument. This historic first climb was part of BioBlitz 2014, a massive effort throughout the Golden Gate National …
The time we have been preparing for during the past few months, BioBlitz 2014, is finally here! For the next two days you will find us at Muir Woods National Monument and the Crissy Field Center as we explore, learn, …
Humans have walked through the redwood forest for millennia, but we first journeyed into the redwood canopy mere decades ago. Recent advances in climbing technology now enable canopy researchers to safely access the highest reaches of the redwood tree tops …
These days, I think it’s a pretty safe bet that many people spend more time on their cell phones — checking email, posting to Facebook, playing games— than they do out in nature. This trend seems especially prevalent among our …
Finally, with the onset of rain, we have amazing mushrooms pushing up throughout the coast redwood forest. One of my favorites is the shaggy mane mushroom, Coprinus comatus. This is a gilled mushroom that emerges with a white scaly cap …
The last 12 months in California have been the driest on record since weather records began in 1885. NASA’s Earth Observatory recently showed us just how seriously the drought is impacting Californian vegetation statewide from the redwood forest to grassy …
Last week I traveled northwards up the coast redwood range to check on weather conditions in the forest at Humboldt Redwoods, Prairie Creek, and Jedediah Smith Redwoods State Parks. Through our Redwoods and Climate Change Initiative, we are studying how …
This week, Nate Stephenson and his colleagues published a new study showing that 97% of tree species grow faster as they age. Unlike in animals whose growth clearly plateaus with maturity, older trees just keep getting bigger and bigger. Large …
If you’ve driven around the country in recent years, it’s likely you’ve seen vast stretches of pine forest wiped out by the mountain pine beetle. This beetle naturally occurs in North American forests, but changing climatic conditions are causing outbreaks …
During a recent walk through Sam MacDonald Park in San Mateo County, I noticed many downed, brown-leafed tanoak trees amongst the towering redwoods. At first I wondered why the county would cut down so many trees, but then I realized …
This fall and winter has definitely been a dry one for us here in California. One thing I’ve noticed is that with limited rainfall comes fewer mushrooms. I have always associated the rainy fall with prime mushroom time. I love …
