Changes in landscape and colonization by various plants as glaciers retreat is a very, very well-documented process. The vegetation changes in the picture shown are unambiguously due to the retreat of the glacier.
Global changes aside, it takes awhile to form soils that will support plant life. Near the foot of a retreating glacier, you'll always have till and moraines. If they've been recently exposed, they'll always be bare. It takes a few decades for forests, etc to get established.

I just say this because humanity really did horrible environmental things throughout our history. For example the ceders of Lebanon being completly cut down by 800 BC and the deforestation of Israel during the crusades which never came back.
- jofer 11y agoThat's all very true, but for that particular picture, the lack of vegetation is because the area was covered by ice only a few years before. Note the lack of soil in the older photo. There's only rocks and silt.
