I will not provide any more Updates to this.
There is a new and much better version of this, that will not replace your current setup: http://www.nexusmods.com/oblivion/mods/46118/

--------------Elbethien's Jungle of Namriel overhaul--------------
                              Tamriel goes jungle
Namriel is not a typo :D
            A tropical overhaul that is inspired by pictures of Vietnam and a little bit Far Cry and Battlefield


I often got requests for my personal setup and it is always sad to say it is nowhere to get.
I wanted to give it away, but I could not get around to really do it. Work, work, work XD and suddenly I did it in three days oO
Carrotferret already published a jungle overhaul recently with many of my changes, but it does not even come close to my vision.
I was even a little bit shocked to see my first attempts again. Those changes/attempts sadly got a little dated.
My vision of a jungle is dark (less tropical island flair I mean) and green, and almost only green, with just a few dots of other colors here and there.

Brittainy started all this, and I'm so glad she did! She made my dream come true.
She provided the base to start with and all the hard work of placing all those palm trees, wow!
After her release I started to heavily alter things, and I did that for a very long time.
My main goal was to get rid of the white spaces on leaf textures from Brittainy's, to better match other tree and grass textures,
but I still use some of them (2 ferns, flowers and some shrubs) .
As you might know, I released a few things already, but that is just not the same...
Now finally it is nearly perfect for me. I hope you like it too :)

You will find a world of thicket in some places, where you might get attacked by something (no creatures added in this mod)
that really startled you, or you'll have a hard time to localize its position. It is really very dense.
I don't want to give away too many spoilers on how regions look. Just explore it and get amazed or annoyed ;)

There are optional downloads to get rid of annoying things, if you don't like too dense. In that case use both optional dls.
----------------
Update Main File:
2 new Ferns, 2 new leafs, more optional banana trees. This work is never done^^

Added a Ubanga patch to be used along with the main Namriel esp (not the esp for Ubanga). It will overwrite the mud roads of northern Ubanga with sand roads. Sometimes land editing was not possible because of a game limit, so there are some spots that still have mud road, but I think this workaround is still the best solution to keep the elephant grass and the rice. It is growing into water and looks amazing in Ubanga.

Optional grass and bamboo leaves:
The grass looks rather ugly and glowing in the distance, so I made something more realistic (in my opinion) Bamboo leaves have a better pattern now.
----------------

Not here:
This overhaul is not high resolution. It is based on Brittainy's medium Res.
It does not include landscape textures. Only the jungle sand-roads. Use Qarl's (best matching) or even vanilla if you like.

To get the palm trees, you have to either use Brittainy's (replacer by me http://www.nexusmods.com/oblivion/download/1000008475 )
or carrotferret's.
I don’t want to provide it, since it has many compatibility issues.
I use it myself, and can live with some floating trees in UL. Unlike the floating, I even love it!
This has changed now! You can find a Unique Landscapes compatible esp under my optional downloads. It is still not complete but most incompatibility issues are solved.

Install:
To install, drop everything in the proper folders, Data/textures/plants into Data/textures/plants
and so on. Overwrite when prompted.
In Oblivion.ini change "iMaxGrassTypesPerTexure" to 3 or more, if you don't have it.
ESP is cleaned with TES4Edit.

ETC and Optional:
Sand-road replacer and tree-shadows are included.
You will find an optional folder in the zip. It contains changes that alter some mushrooms into banana trees.
Only install it, if you don't mind that a mushroom looks BANANA :D
I also made a second esp for Ubanga users (optional download). Ubanga would have no roads in some northern regions (mud-roads).
Talking about Ubanga, maybe I just got used to it, but I find this fantastic in Ubanga! Alimals and my texures mix well together,
I even use some here too.

One Family:
Here are some recommendations. They are my mods, and actually all belong together, into my jungle-monster.
Tropical Weather Spell:http://www.nexusmods.com/oblivion/mods/45638 compatible with all weather mods!
Additional Groundcover:http://www.nexusmods.com/oblivion/mods/45589
Jungle Ambiance: http://www.nexusmods.com/oblivion/mods/45568

My overhaul looks different in color:
That is normal. Weather mods/conditions can have a great impact on colors.
Also ENB, OBGE and OR and other settings can make big differences.

If you have something to complain about, complain. I will listen and most likely help, if it isn't too much work.
I will not make everything darker, or less green or such things, but if you see a unfitting/missing texture, I can provide solution quite quickly.

My water settings in OBGE or OR if anyone is interested:
shoreFactor            to 1.0
turbidity                 to 11.0 test also lower settings
ScattCoe                to 0.12
ExtCoeff_R             to 0.12
ExtCoeff                to 0.14
ExtCoeff                to 0.34
depthDarknes         to 0.3
