Snow on spruce trees is a hallmark of the Canadian winter. While most PEI plants lose their leaves or disappear altogether as temperatures drop, you may not have thought about how and why conifers take a different approach. Today, we take a look!     Broad-leaved trees like Maple, Beech, and Birch produce big leaves with huge surface areas that are very efficient at catching sunlight and turning it into food for the tree. Even if those leaves didn’t freeze, they lose water an

Few PEI scenes are more beautiful than frosty winter mornings like the one we had last week. Under certain conditions, ice crystals coat trees, twigs, and fence lines, turning the landscape into something magical. We call this ‘hoar frost’, but there are actually two very different types of ice that cause this phenomenon. Let’s take a look!   ‘Hoar’ is an old word for feathery white, like a beard. It’s an apt description for the delicate, feathery ice crystals that form true

The Island’s winter landscape is mostly monochrome, making the occasional burst of colour all that more beautiful. One of my favourite bright spots is the aptly-named Maritime Sunburst Lichen ( Xanthoria parietina ). Lichens are interesting in many ways, including how they survive our coldest months. Most living things go to great lengths to protect themselves from drying out or freezing: two major (and usually lethal) side effects of winter. That’s why PEI’s trees, plants, f

There have been some bitterly cold days this winter, with temperatures well into the minus teens and twenties Celsius. Clear, cold days are great times to be in the woods, but you may notice some unusual noises: the snap, crackle and pop of trees! Media have been having fun with sensational ‘exploding tree’ headlines, but let’s look beyond the clickbait. A clear, bitterly cold day in the woods on PEI. Trees do their best to prepare for winter. This includes getting rid of tho
