Turning trees into wonders

[uanime5]

I recently tried modifying the 'descr_climates.txt' to turn trees in unused climates into wonders. Though I was successful there were two problems.

Spoiler Alert, click show to read: 

1) I was unable to make an area with just one tree (for some reason each pixel has 3 trees).
2) The wonders swayed in the wind.

Does anyone have any ideas how to get around these problems. If successful it would mean that there could be additional wonders on the map without needing to use resources.

Question from an M2TW wonder newb. Can wonders, ala the ones from RTW be added to M2TW as vanilla at least doesn't use any that I recall.

You replaced the models, but not the configuration or the animation for it. Try using the 'sparse_tree' entry and experiment with the numbers at the end of the line.

If I remember correctly, then EB (RTW version) had little 3D rocks in the desert. Not sure if those came in clusters as well.
