Where HWWD does foliage, I do birds. Here's an old post on how Calypte anna or Anna's Hummingbird has been gradually expanding its range into the interior of Vancouver Island. And here's another on how the Northern Mockingbird (Mimus polyglottos) has been pushing North into the GTA, its numbers, if you go by the Toronto Ornithological Club's Xmas bird count, having tripled in the past ten years.

Sounds good. More birds and trees.
Not so good, see a nice presentation:

*You* get to have kudzu, a plant species you will not like much.
See page 45 for when.

Sure, look carefully at a 25 year old photo, shot either as a slide or a color negative, likely faded with time, saturation and contrast unknown, with a recent, and likely digital photo.
Next, shoot the photos at different times of day (notice difference in shadows) under undetermined level of cloud cover and . . . eureka!!! Global warming!
PS. Note carefully how dramatically AGW has affected the colour of the water too.
The point, Paul, is that the vegfetation is quite bit thicker today, esp. on the Northern(?) most island.
