Despite the graphic, it seems like the uniform grids wouldn't work well on this image since the grass objects are not distributed very evenly in size or space (they're very rectangular)

I'm not sure what you mean by that - to me, it seems like each blade of grass looks almost exactly the same in terms of the size and shape of its bounding box, so as long as we're only interested in rendering this lower portion of the image and not the sky above, using uniform grids should do a pretty good job of evenly distributing objects throughout the grid.

I agree with moridin22; we have the grass fairly evenly distributed throughout the space with similar bounding boxes, so it seems that uniform grids should work well. The example on the next slide of the "teapot in a stadium" problem would be a case where uniform grids fail to perform well, given the large variation of objects in the scene.
