One field hazard that is a particular problem when going off trail are ticks.
I was a very aware I might be in a tick zone having been near this place about a year ago and finding nearly a dozen ticks on my legs. It has been a long time since I have been bitten in part due to vigilance.
An irritating but significant less threat are the seeds that attached to my socks. June is rather bad for various grass seeds. I had a range of species that I was aiding by moving them to other territory. I try to avoid cheat grass entirely as their seeds are thick and very hard to remove. I believe these were mostly if not all native including the aptly named needle-and-thread grass (Hesperostipa comata). A bit early for the seeds, but it has been very warm.
Typhoon, a favorite band, has several songs inspired by Kyle Morton's encounter with a tick.
