My institution doesn't put their name on most of those types of vehicles. That way when it's parked in front of a bar there's less chance of embarrassing consequences.

Students in my summer natural resources class with the Florida champion longleaf pine (*Pinus palustris*). On private property near Newberry, Florida. Students choose from field trips focused on private land management, ecosystem services, invasive species management, and ecosystem restoration.

Pine stand

Pine stand

Longleaf pine (*P. palustris*) / slash pine (*P. elliottii*) stand on a spodosol in N. Florida. Understory primarily wiregrass (*Aristida beyrichiana*), saw palmetto (*Serenoa repens*), gallberry (*Ilex glabra*). Prescribed fire every other year, it will burn again this summer.

I mentioned naval stores last week. Here’s another industrial use. Subfossilized resin from Agathis trees (#Araucariaceae) in New Zealand was prized for varnishes. Gum-diggers excavated tons of the stuff. πŸ“·: An Old Gum Digger of Houhora, North Auckland, Archives of NZ CCBY2 #resin #Botany 🌾πŸ§ͺ🌱

I'm not an expert but generally growing season burns are preferred for restoring and maintaining wiregrass and other understory plants. That's ~ start of thunderstorms in June until August-ish. Dormant season / winter burns I think are preferred for more difficult situations like high fuel load.

If you're waiting on a reply, a peer review, or other effort from me--please be patient. I urgently left to document a developing forest die-off event more intense than any I've seen. No obvious biotic agents, dead & dying include multiple Pinus & Juniperus, many Quercus, & shrubs. #WhatKillsTrees
