Discovering the Climate Change Resilience of Coast Redwood Forests

on

After a decade studying the impacts of climate change throughout redwood forests, Emily Burns, PhD, and Stephen Sillett, PhD, share new insight into how coast redwood trees are growing today. See the remarkable new findings about second-growth forests.

Watching Ferns in the Redwoods for Signs of Climate Change

on

The sword fern, one of the most common redwood forest plants, has become prominent in my life over the past few years. This is mostly due to the League’s Fern Watch project, which monitors the health of sword ferns throughout the redwood range. Even though these ferns are common, little is known about their ecology and how they respond to climatic change.

An Earth Day for Science

on

This year’s Earth Day theme was focused on environmental and climate literacy, which means that we need to make sure everyone is educated on the impacts of climate change on our planet and the actions we can take to protect and sustain our environment.

High School Students as Community Scientists

on

If you ask high school students what the impacts of climate change have been, they can tell you that the polar ice caps are melting, that we have extreme weather, and that California has been in a drought for the past few years. But if you ask them how climate change will affect our forests and the plants and animals that live in them, they find it harder to come up with an answer.

Future Coastal Climate Not Cool for Redwood Forests

on

In a study published in the research journal Global Change Biology, climate scientists from the University of California and NatureServe conclude that a warmer future with normal rainfall on California’s coast will leave coast redwoods south of San Francisco Bay with significantly different climate than they have experienced for decades.

New Study Provides Coast Redwood Climate Forecast

on

Understanding how climate change impacts the world’s tallest forest is like assembling an incredibly large jigsaw puzzle; the full picture emerges slowly, one piece at time. But occasionally, a critical piece falls into place…

Redwood Research Proposals Wanted

on

Save the Redwoods League uses redwood science to guide our conservation work and we are ready to invest in new studies that will help us save the redwoods. Since 1997, we have supported redwood and giant sequoia forest research on …

Lower Genetic Diversity Puts Giants at Risk

on

Recent League-funded research by Richard Dodd, an Environmental Science Professor at the University of California, Berkeley, confirms that northern groves (north of the Kings River drainage) have lower genetic diversity than central and southern groves. This could have profound consequences for long-term conservation strategies for the species, especially considering the changing global climate.

Redwood Weather

  RCCI researcher Wendy Baxter describes below why we are tracking weather in the woods: Monitoring the local weather and long-term climate is an integral part of the Redwoods and Climate Change Initiative (RCCI). Beginning in 2011, scientists from UC …

77% of Birds and Climate Change Studies Use Community Science

on

This study speaks to the incredible need to continue community science projects because they are critical to learning about the planet in a rapidly changing environment, and the volunteer contributions are significantly pushing the research field ahead.

Salamanders in the News

on

It’s not often that salamanders make the New York Times.  But last week, the ‘Science’ section featured an article on a study investigating the role of salamanders in the global carbon cycle. Basically, salamanders are among the top predators in …

Bay Area residents got a sneak peek into the hopes and dreams of the Department of the Interior last week when Secretary Sally Jewell came to Crissy Field (external link) to announce the department’s new campaign to connect the next …

A Redwood of a Blog: How the Giant Trees Grow

on

RCCI’s nursery experiments and tree ring analyses are essential to understanding the past and future of the redwood forest, but it is the trees themselves that tell us about its present. By establishing 16 large plots in old-growth forests throughout …
