We’ve reached that time of year when my weekly posts switch from plants and fungi to wildlife tracks and sign. Here’s a nice reminder that not all tracks are made by feet! The dry summer weather made for great tracking conditions along PEI’s unpaved roads. This site near Mount Stewart had all sorts of footprints from insects, birds, and mammals, along with the unmistakable undulating trail of a snake. The size of the snake track told me which of our three species was the culp

Welcome to the final Mushroom Monday of 2025. We’ll end with a large and easy-to-identify species that hasn’t been recorded all that often on the Island: Northern Tooth ( Climacodon septentrionalis ).   As we’ve seen throughout this series, mushrooms come in all shapes and sizes, and can share physical traits without being closely related. The spore-bearing surface of Northern Tooth has spine-like ‘teeth’ rather than gills, folds, or pores (inset photo). Despite this, it is m

If I had to design vegetation for a movie set on an alien planet, I’d take inspiration from this PEI plant: the odd-looking Rough Cocklebur ( Xanthium strumarium ).    Cocklebur gets its name from spine-covered fruit (burs) that look a bit like Burdocks but have two distinctive beaks at the end (inset photo). Like Burdock ( Arctium minus ), Cocklebur’s Velcro-like fruits are distributed by hitch-hiking on animals, including humans. Those burs also float, allowing them to be r

Welcome back to Ask a Naturalist, your own personal Google for information on all things natural on PEI. Today we have an insect that people often mistake for a fungus. Meet Woolly Alder Aphids ( Prociphilus tessellatus ).   From a distance, Woolly Aphids do look like some sort of fluffy, fungal mould on the branch of a tree. But take a closer look and you’ll see that those fuzzy clusters are actually dozens – sometimes hundreds – of individual insects crowded together.   The

PEI has more than 30 native, wild plants with edible berries, but here’s one of the lesser-known: Bearberry ( Arctostaphylos uva-ursi ).     Bearberry doesn’t compete taste-wise with some of our other wild fruit. Raw, the berries are dry and bland (but that’s probably just as well, because too many raw berries can have a laxative effect). Cooking improves their flavour and texture, and Bearberries make pleasant preserves, interesting additions to soups or stews, and excellent

This fall, we’ve been exploring some of PEI’s least-common trees, including Balsam Poplar, Ironwood, and Jack Pine. Today it’s one many people haven’t even heard of: Bog Birch ( Betula pumila ).   We often think of Birch as among the majestic trees of PEI’s early forests. Nineteenth century writers told of Yellow Birch ( Betula alleghaniensis ) three to four feet in diameter, and it was said that Mi’kmaq people were able to make a six-person canoe from the bark of a single Wh

You may think of summer as peak season for PEI’s wild berries, but a few tasty treats are at their best this time of year. One of my fall favourites is Wild Lily-of-the-Valley (aka Canada Mayflower, Maianthemum canadense).   Wild Lily-of-the-Valley is NOT the same as the popular garden plant of the same name. The sweet-smelling European Lily-of-the-Valley ( Convallaria majalis ) contains toxic cardiac glycosides that can cause nausea, vomiting, diarrhoea, and irregular heart
