you dont have to do anything with it (well you can go to the cliffs and break the level 4 stone to the right after you climb the first vines)
In Pokémon XD: Gale of Darkness, you can obtain Salamence by first catching a Bagon, which can be found in the Orre Region's Relic Forest. After capturing Bagon, you need to evolve it into Shelgon at level 30 and then evolve Shelgon into Salamence at level 50. Alternatively, you can also obtain a Salamence by purifying a Shadow Bagon, which is available from a trainer in the game.
You can catch it but you will be forced to release it. Salamence requires a certain ammount of strategy and skill to capture. Try to obtain a Pokemon with a Fighting-type PokeAssist and use it on Salamence. You will also need a full blast of Plusle or Minun's electric PokeAssist if you want a chance of capturing Salamence. As said above, you cannot keep Salamence and you will not be able to capture it after the first time you encounter it in the Jungle Relic. You can capture when it is flying. That is the most easy way to capture it. To make it fly, draw a loop around it once.

The trick to catching Salamence in Pokemon Ranger is strategy. You have noticed that Salamence flys alot and crashes down. The trick to capturing it is using various PokeAssists. Try capturing a Fighting-type Pokemon before hand - or if you can't capture or take a Pokemon into the challenge, use Plusle or Minum's Assist. Circle Salamence quickly while it is paralysed. The rest is all up to skill and chance. Update: Personally I don't find a reason to use your Poke Assist, just wait for it to jump into the air, if you really are scared of it coming down to early use Plusle or Minun, but otherwise you can see it's shadow and just circle it's shadow, the shadow becomes bigger as it comes crashing down (I think, it's been so long since I caught Salamence)
catch bagon at meteor falls and evolve it into shellgon then evolve it to SALAMENCE bagon lv31 shellgon lv50 salamence
Shelgon evolves into Salamence at LV. 50
you have to catch a bagon then evolve to shelgon then evolve to salamence
Salamence doesn't evolve, it's the final stage.
Salamence is the final form, it cannot evolve afterwards.
Salamence is a Dragon and Flying type pokemon.
Get a Bagon in the Safari Zone. From there, evolve it into Shelgon and then Salamence.
