Cenarion Expedition

The Cenarion Expedition is a faction of night elves and tauren based in Zangarmarsh and led by Ysiel Windsinger. The Expedition was sent by the Cenarion Circle to Outland shortly after the Dark Portal was reopened in order to study the surviving life forms of that uncharted world. Although it began as a small organization directly controlled by the Circle, the Expedition has grown to become an autonomous organization, independent of the Circle's leadership on Azeroth. In fact, Circle reputation (regardless of how good or bad) bears no weight with the Expedition, and all characters begin at neutral with them.
The primary base of operations for the Cenarion Expedition is Cenarion Refuge in eastern Zangarmarsh. Additional Expedition outposts are located in Hellfire Peninsula, Terokkar Forest and Blade's Edge Mountains.
The Druid organization D.E.H.T.A. in Northrend is also aligned with the Cenarion Expedition, and their quests give reputation with this faction.
At some point, the Cenarion Expedition requested help from the Omenai at the Temple of Telhamat, in order to study what happened in the region and help reverse any damage possible. Amaan the Wise accepted and later sent the adventurers in support.Helping the Cenarion Post (Alliance)

===Neutral to Honored===
As soon as you reach Level 62, head to Zangarmarsh and look for Darkcrest and Bloodscale Naga (and their slaves) to grind. Run Slave Pens or Underbog whenever you can; a good instance run with a capable group will get you more reputation faster than soloing mobs outside the instance.
Alternatively, at level 60, you can start turning in . Every time you complete a turn-in, Lauranna Thar'well will give you a . These packages have the chance to contain an , an item which begins a repeatable quest. Each Uncatalogued Species you hand in gives 500 reputation. Save these for later, as they continue to give reputation after reaching Honored. The more of these you can turn in, the more chance you will have of getting an Uncatalogued Species, which will make it a shorter grind to /. 
This quest is no longer available once you reach Honored, so make the most of it while you can. Ideally, you will want to do this quest 36 times, turning in 360 Unidentified Plant Parts (last turn-in can be done at 5999/6000 ). You may even want to avoid Slave Pens or Underbog runs before you reach , to make sure you can have all the 36 turn-in, so that the chance of getting is maximized. It is possible to get as many as 7 or 8 if you are lucky. This can save you a few Steamvault reputation runs later. (Together with the other reputation quests, it is even possible to reach Revered without a single instance reputation run!)
 
If you are an herbalist, and interested in Sporeggar faction, you may want to grind the Bog Lords which can be found in each of the corners of Zangarmarsh (Northeast, Southeast, Southwest). Their bodies can be "picked" by herbalists and often yield Unidentified Plant Parts, while every kill yields 15 reputation with Sporeggar.
Between running Slave Pens and Underbog and handing in Unidentified Plant Parts, it is very easy to reach Honored.
===Honored to Exalted===
Once you are running Slave Pens and most of Underbog on normal mode will no longer grant reputation.
Now is the best time to do the Cenarion Expedition quests. There are quests in Hellfire Peninsula, Zangarmarsh, Terokkar Forest, Blade's Edge Mountains and Netherstorm. 
It is also the time to turn in any Uncatalogued Species you have found. Doing this should get you part of the way into Honored.
Apart from quests and Uncatalogued Species, you have multiple options for reaching :
* Run normal Steamvault, either in a group or solo once you reach the level cap. Each run gives 1,100-1,662 reputation depending on how thoroughly you clear the mobs.
* You may also run Slave Pens, Underbog, and Steamvault on Heroic Mode once you are Honored. Regular mobs are worth 15 reputation, 2 for non-elites, and 150-250 for bosses, for a total of 2,500-2,750 reputation for a full clear. The reputation gain in Heroics is about 50% more than running regular Steamvault, but Heroics are much harder and each Heroic instance can only be done once per day. However, Heroic bosses also give Justice Points to players in the relevant level range. These can be spent toward pre-raid epic gear.
* D.E.H.T.A. offers the Repeatable Quest Can't Get Ear-nough... in Borean Tundra. This quest asks the player to kill Nesingwary-affiliated NPC's and collect Nesingwary Lackey Ears. Fifteen ears yield require 20-25 kills, and provide 150 repuatation before perks.
* Until Patch 4.3, there was a Repeatable Quest from the Steamvault for the hand-in of . This quest, along with a handful of other Outland repeatable quests, appears to have been removed as an undocumented change in Patch 4.3.
