Why wasn't Safari Zone in the Johto location guide?

Question

I only saw Safari Zone Gate instead of Safari Zone.

Okay so if you were going to make it now, here are the Pokemon that appear:

Plains

Walking

Rattata Lv 15-17 (Morning, Day)
Abra Lv 15-17 (Morning, Day, Night)
Girafarig Lv 15-17 (Morning, Day, Night)
Smeargle Lv 17 (Morning, Day)
Raticate Lv 15-17 (Night)
Stantler Lv17 (Night)

I'll edit when I find more Pokemon that appear. Plus this is for Pokemon HG/SS.

Ledian, we need to battle LC for our gym tourney battle, so make a team if you haven't already, and get to chat. I should be there pretty much most of today.
