The world still seems to generate less foliage compared to Java Edition even after the parity changes introduced in the 1.21.60.23 Preview. Not only is this especially noticeable in the plains biome and other generally flat areas, but less or almost no foliage can also be observed in underwater areas.

Steps to reproduce:

1. Launch Minecraft Preview (1.21.60.23 and above)
2. Create a new world in creative mode
3. Navigate to a plains biome
4. Observe your surroundings.

Expected Result:

Like Java Edition, both tall and short grass are significantly more present and generate frequently in large clumps. The oceans are also filled with more kelp, and flowers are more prevalent in Flower Forests or in other biomes known for having a lot of Flowers. There is generally more foliage in general across all locations in the world.

Observed result:

There is more grass present compared to previous previews or release versions, but unlike Java edition, there is significantly less of both tall and short grass which is also more spread out. Oceans can sometimes have almost no kelp and consist of only seaweed (Fixed in 1.21.60.27) . Flowers are also less common in many flower-bearing biomes. There is generally less foliage in general across all locations in the world.

Notes:

To be clear, this is not meant to be a duplicate of MCPE-141364. Rather, this post is directed toward the changes made in 1.21.60.23 that do improve the overall generation of grass, kelp, flowers, and other plants in their respective biomes and locations. While foliage generation is better, it still needs some fine tuning, and it would be best to give generation more tweaks over the next couple of Previews until the community is satisfied.
