Firewood Survey and Exchange Questions May we discuss firewood pests with you? Did you cut it yourself? EXPERIENCE YOUR Did you get it near Yosemite? AMERICA Are you aware of California quarantines on host materials for sudden oak death and pitch pine canker diseases? Do you know what kind of tree this came from and where and why it was originally cut? Where has it been stored (indoors/outdoors what county)? Did you notice any sawdust-like frass under it when you loaded or moved it? Have you noticed anything crawling/flying that might have come from the wood? If you squashed any bugs do you still have them or can you describe them? May we check for loose bark or frass in your open vehicle or storage container?

Do you plan to burn all of your wood here or take leftovers back home or to other camping location(s)?
