From the Redwoods Forest to the Gulf Stream Waters: Mapping Redwoods Helps Conservation Efforts

This post is part of this week’s featured projects about other tree projects. Branch out into citizen science and take a look!

RedwoodsStanding among Redwood trees is truly a humbling experience – driving amidst these giants of the plant kingdom, I couldn’t help imagining I had time-travelled back to Earth’s Mesozoic Era when dinosaurs roamed the earth. Yet, in the throes of climate change, even these titans are threatened as their ecosystem changes. To address this, Save the Redwoods League (SLR) has launched the Redwoods Watch project to harness the power of citizen scientists to map these trees across the globe.

By understanding the climate in which redwoods currently exist, the scientists at SLR can figure out how their habitat has been altered in the last century and predict where it will shift as a result of climate change. This is critical information for SLR, as their Science Director Dr. Emily Burns states, “If we know where the trees are, we’re going to make better decisions as we’re doing our other conservation activities.”

To participate, citizens need only to download the easy-to-use iphone app, snap a photo of the specimen, and submit the evidence. The app uses the phone’s GPS to record the location of the tree, and this info is correlated to produce a map of the redwoods. To help new users, SLR has produced a short video informational video:


Dr. Burns describes that one of the reasons for taking the citizen science approach to tree mapping is that SLR is “hoping to get folks out into corners of the redwood forest that we don’t visit frequently.” However, you can still help even if do not live near a native forest – SLR is curious about horticultural redwoods too, the data are just used differently. Whereas redwoods mapped in their natural areas help with climate modeling predictions, the redwoods mapped in horticultural settings help to understand the extremes in which the trees can exist.

So don’t worry if you’ve never stepped foot in a redwood forest. Dr. Burns asserts, “We encourage people to, when they see a redwood, let us know about it.”

She received her BS and MS degrees from Northeastern University, and her thesis work examined fuel cell catalysts under real operating conditions. She loves learning about energy and the environment, exploring science communication, and investigating the intersection of these topics with the policy world. When she’s not writing or in the lab, you’ll probably spot Emily at the summit of one of the White Mountains in NH. Follow her: @lewisbase,
