A couple of years ago while the fire lane on the south tract was being maintained or something, the tractor tires dug deep ruts into an area that had the highest concentration of an endangered plant species called Polygonella basiramia that had been flagged in hopes the area might have been treated more gently.
There had been about 300 plants in this area.
Last year I checked the site and didn't find any plants there.
I checked recently and located a handful of plants, so perhaps they are gradually coming back.
I'll have to recheck next year to see what the status is.
