I made a thread asking about this and nobody could reply substantially, so I spent a couple hours this morning and did some testing.

Some generalizations:
Tall Grass and Brambles are not functionally different.
Negative terrain under contiguous plant cover doesn't slow pawns down further.
Plants do not have "clamber," unlike stone chunks.

Notice in test 1, lane 13 is identical to 9-11. With the lack of clamber, we can say that walk speed in marshy soil is equal to walk speed in brambles.
Notice in test 2, Lane 11 and 2 are equal. Grass and soil are both 87%.
Notice in test 2, lanes 12 and 7 are equal. Berry bushes and marsh are both 30%.

Conclusions:
A newborn(5% grown) plant and a fully mature one have the same walk speed.

The exact walk speed of bushes is 30%.
   - Needs testing for alternating bush/trees if possible.

The exact walk speed of tall grass and bramble is 46%, equal to marshy soil.
   - The answer to my original question. Less effective than alternating chunks but free in materials and labor, so sometimes worth it after all.

The exact walk speed of grass is 87%, equal to soil.
   - There's no point removing normal grass from soil, stony soil, rich soil etc.

The walk speed of trees is approximately 10%, but they cannot be grown in a solid row. The walk speed of alternating trees is approximately 15%.
   -Compared to chunks, trees give half the cover and impede movement around twice as much, making a corridor of alternating trees technically superior to one of alternating chunks, as long as they don't burn down. Obviously requires major planning ahead and fire control systems, but frees up stone supplies.

Speaking of fire control systems, I forgot firefoam. It might interact with some of these cases.

12 "baby" poplar
13 "baby" tall grass



My game is modded to hell, but I don't think anything changes movement speed. I also likely made some sort of mistake. Feel free to try to falsify these results or test further. Feel free to put this on the wiki if I don't get around to it.
