We are excited to share not one but 2 new resources we've been working on quite a bit the last few months around wildland fire smoke--one is a synthesis on public opinion on prescribed fire and associated smoke, and the other is a long-form research brief that summarizes 6 review articles on wildland fire smoke risk communication (yes, a long brief is a bit of an oxymoron but we think its a valuable resource nonetheless!). There is also the regular recap of all the new pubs, resources, and news below as usual. Read on for all the deets, and as a reminder, if you've missed any of our recent newsletters and the breaking resources they contain, you can always find them all here. As always, please don't hesitate to reach out if you have any questions, resources to highlight in future newsletters, or other news to share; we are always happy to hear from you.
