I’m apparently not the only one favoring large-plated hard pines in these east KY woods
Super cool and valuable Ozark fire history video by Denise Henderson Vaughn, including helpful context for the very (very) freq fire shown in shortleaf pine scar records from the region. @oakfirescience @FireScienceGOV

!! TEASER ALERT !! Watch "Remembering Fire," a short video on Ozark #firehistory featured in a new ArcGIS StoryMap about the history and use of fire in the Ozarks by @oakfirescience. Stay tuned for tomorrow's StoryMap release! #firescience Video link: vimeo.com/918345147
Unloading fire scars on #firescarfriday, great way to wrap up an awesome/incredible week of sampling #shortleafpine in the Missouri Ozarks!
Stoked to run into this monster Sierra Nevada ponderosa pine (#firescarfriday)this week, with cool (multiple episodes?) modifications as a bonus. Note the notepad for scale 👀
#firescarfriday eye candy? Missouri Ozark shortleaf pine during a late winter rx fire.
munewsarchives.missouri.edu/news-releases/… Have you heard of the infamous 'New England Dark Day' of 1780? Smart colleagues of mine used tree rings to shed light on this mystery, in an article from 2008- maybe even more relevant today.
Our lab has non-fire history work in the northern CA woods this summer, but we’re constantly running into awesome fire scarred remnants like this one. I must admit to being a little relieved to not have to collect this giant, even on a #firescarfriday 😂 @kyle_rolfes
Nope-rope (western ratsnake, right?) warning me (very successfully) with a cool faux rattle today while mushroom hunting. A likely sign, along with numerous ticks, that the season is wrapping up.
Flagging and tagging fire scars IRL on #FireScarsFriday, a rare treat! #centralAppalachiansRock! and #wherewasntfrequentfire?
What’s the best time of year to be in the woods, and why is it early-spring for you?
