Please, I would like to understand the meaning of the expressions GONE SPOOR and GONE SCAT from the following Gary's Lawless poem:
I will be waiting for someone's help. Tks a lot....

Treat each bear as the last bear.
Each wolf the last, each caribou.
Each track the last track.
Gone spoor, gone scat.
There are no more deertrails,
no more flyways.
Treat each animal as sacred,
each minute our last.
Ghost hooves. Ghost skulls.
Death rattles and
dry bones.
Each bear walking alone
in warm night air.
