What do the new symbols on the sniff bar mean?!

[Silver Arrow]

1. What are those palm tree thingy majigys and when you get to that that is all you see on the sides of the sniff thing?
2. What are those footprint marks that do the same as those palm trees?
3. There are like these circle things that look the same as the other ones

I haven’t played this in a long time so you can hopefully understand why I am confused. If you know what these are, please tell me in the comments. I also saw literally no one throughout the whole thing and I don’t know if that is because the map is huge but there were 92 players in the server so it can’t be so big that I can’t see anybody around. Thanks to those who can help me in the comments, until next time, bye

1. Sanctuary: A small area for hatch-lings and juvenile animals to receive a perfect diet (small red mushrooms that cant be sniffed out) to start out life. At least for herbivores and omnivores. Young carnivores have to hope herbs show up there to hunt and adult troodons and enter without repercussions. Once u get too big the mushrooms there wont give diets anymore. 2. Mass Migration: A location where multiple species of herbivores and omnivores can find diet plants there, carnivores have to hope herbs show up to eat there. 3. Patrol Zones: These are like mini migration zones for individual animals or groups, a much smaller amount of diet food can be found there. Hope this helps.
