Nature lovers rejoice! We’re coming at you with a complete guide to how to identify a tree in Alberta.
With about 180 tree species in Canada, 28 of which are found in Alberta, and over 318 billion individual trees, our country knows dendrology.
What’s even more impressive is that with close to 362 million hectares of woodland area, Canada is home to 10% of the world’s forests.
How to identify a tree: Start by learning the 2 main types
Trees, whether they’re in Alberta or anywhere else in Canada, are divided into two broad categories:
- Deciduous: Also called broadleaf or hardwood trees, most deciduous trees drop their leaves in the fall.
- Conifers: Also known as evergreens, softwoods, or needle-leaved trees (with some exceptions), most coniferous trees keep their needles year-round.
Now that we’ve defined tree types, let’s cover how to identify a tree starting from these two broad categories. Our team of professional arborists have put together expert tips and tricks for tree recognition that you can use year-round.
A quick guide for how to identify common tree species in Alberta
What if you’re an Albertan who can’t identify a tree? Not to worry. There’s a quick way to do it.
Use the Guide to the Common Native Trees and Shrubs of Alberta key to help you quickly master the art of identifying trees:
- Leaf type:
- Broadleaf (deciduous trees),
- Leaf arrangement:
- Simple: one main leaf per stem.
- Compound: many small leaves (called leaflets) per stem.
- Leaf arrangement:
- Broadleaf (deciduous trees),

- Leaf pattern:
- Opposite: Leaves are attached opposite each other along a stem.
- Alternate: Leaflets are attached alternately to one another along the stem.

- Needle (coniferous trees)
- Needle arrangement:
- Sheathed Needles: Two needles attach together at the same point on the stem.
- Unsheathed Needles: One needle attaches on its own on the stem.

9 of the best tree identification guides
If you’re the type that likes to kick it old school, then a physical guide is for you.
With dozens of options of guides, some of which are hardcover books the size of a phonebook, we’ve narrowed down the list for you to 9 of the best paperbacks:
- National Geographic Pocket Guide to Trees and Shrubs of North America by Bland Crowder
- National Audubon Society Trees of North America
- The Sibley Guide to Trees
- A Peterson Field Guide To Western Trees
- What’s that Tree? A Beginner’s Guide by DK
- Trees of Western North America
- Trees and Shrubs of Alberta by Lone Pine
- Trees and Shrubs of Alberta by Kathleen Wilkinson
- Plants Of The Western Forest: Alberta, Saskatchewan And Manitoba Boreal And Aspen Parkland
Or, you can save trees and choose a tree ID app instead. We’ll leaf through these options next.
Easy tree identification: There’s an app for that
Say goodbye to telephone book-sized plant identification guides. Now you can get the same amount of information in the form of a tiny app.
In the age of smartphones, a germinating arborist can have the power of plant recognition at their fingertips. (Or, is it at their thumbs?)
Stop carrying around heavy field guides and start downloading digital tree field guides.
Next up: we’ll share a list of tree ID apps to get you started.
The 10 best apps for identifying trees
Here are 10 of our favourite tree identification apps. Most come in a basic free version and a more extensive paid version. All are available to download from the Apple and/or Google app stores.
- Deciduous Trees 2.0
- Identitree Starter Kit
- iNaturalist (& Seek by iNaturalist) for Android/iOS
- LeafSnap-Plant Identification – Android/iOS
- MyTree App
- My Tree ID by Texas A&M Forest Service (TFS)
- PlantNet Plant Identification for Android/iOS
- vTree Virginia Tech Tree ID by Virginia Tech Dendrology
What if you’re not interested in rifling through an app to figure out what plant you’re looking at, why not get your phone to do it for you? Find out what we mean next.
How to identify a tree with a photo
Photo identification is another option for tree lovers. It works like Shazam for photos. The principle is simple:
- Snap a picture with your phone of a tree you want to ID,
- Upload the pic to a photo ID site,
- Click identify, and
- Wait for your answer to arrive!
If you’re wondering where to get started with photo recognition software, here are two options:
- Google Lens: Technically an app, Google Lens lets users use their desktop smartphone camera or an existing image to search for what they want.
- Snap a photo of a tree you’d like to ID and—Bam!—Lens will tell you what it is.
- Lens is available on all devices, by typing google.ca in your website browser, and in your favourite apps.
- [email protected]: This is a website that works in a similar way to Lens. The big difference: it’s plant-specific and covers more than trees.
If you’re a tech nerd who doesn’t want to go the retro field book route but wants to do more than use click-n-name photo identification, we recommend using an online interactive key.
Read on to discover our list of favourites.
How to identify a tree using an interactive online field guide
Somewhere between paperback field guides, apps, and photo identification tools are online field guides. These interactive tree identification keys are step-by-step tools you can use to ID plants.
A few examples include:
- Interactive Tree Identification Key by Iowa State University
- What Tree Is It? by OPLIN
- Tree Guide to Trees by National Geographic Kids
- Tree Identification Guide by Discover Life – very dated in terms of design but still helpful!
- Guide to the Common Native Trees and Shrubs of Alberta – although more of a manual user guide than an interactive tool.
What if you’re out in the wild without your field guide, manual, or phone? Gasp! Or, what if you’re the type who wants to learn how to ID trees using simple tips all year long?
We can help there, too. Keep reading for our seasonal tree ID’ing tips.
Tree identification tips for every season
Budding horticultural experts can use the following seasonal-tips to name any tree no matter the weather.
Keep these main characteristics in mind when naming Alberta trees:
- Location & Distribution
Different characteristics will help you name trees during different seasons.
We’ll begin with the trickiest season for plan identification: winter.
1. Winter: All about the bark
The best way to identify Alberta trees in the winter is by 3 things:
A quick way to narrow down which tree species you’re looking at in the wintertime is whether or not it’s missing leaves (deciduous) or whether it still has its needles* (coniferous).
*The one exception to this rule: the larch, a coniferous tree that is not an evergreen because it drops its needles in the fall.
After Alberta broadleaf trees have dropped their leaves, the best way to identify them easily is by the colour and texture of their bark. Is it pale or dark? Furrowed or smooth? Papery or flaky?
What about colour? Is the bark:
- Greenish-white (aspen)
- Silver (beech)
- White (birch)
Scan the trees in your neighbourhood and on your property and you’ll quickly be able to pick out distinct shapes.
If a tree is conical, or shaped like an inverted cone, it’s most likely an evergreen.
If the tree is a hardwood, look at the branches. Do the branches grow out from the trunk horizontally or more vertically? Does the overall shape bend gracefully upward, like a curved funnel, or does it appear more angular and thick throughout?
2. Spring: Buds and flowers for the win
In the spring, two these two details to give a name to Alberta tree species:
Buds are great details to help ID trees. They can be used throughout the winter and spring and look the same regardless of how old a tree is.
What is the shape, size, colour, and form of the buds? Are they scaly or smooth? Bare or covered in peach fuzz? Do you notice a larger bud at the end of the twig (terminal buds) or only buds along the twig (lateral buds)?
Twigs can be used all year to ID trees as well. Take note of their texture (are they smooth or ribbed?), and whether or not they have hair or spines.
Alberta trees only bloom in the spring. Their flowers are a great help with tree identification because they vary so much in their colour, scent, arrangement, bloom timing, and reproductive structures.
- Broadleaf trees have flowers for reproduction, and
- Conifers generally have cones for reproduction.
3. Summer: Leaves, please
Finally! It’s summer. Arguably the easiest season for ID’ing trees, novice horticulturalists can finally use leaves to help name their local trees.
Here are the characteristics to look for when identifying broadleaf species via their leaves:
- Shape. Common leaf shapes include:
- Cordate (heart-shaped)
- Deltoid (triangular)
- Lanceolate (long and narrow)
- Lobbed (oak)
- Round (orbicular)
- Ovate (egg-shaped)
- Palm-shaped (maple)
Similar species of trees may have the exact same shape of leaf but their size is different.
Similarly to flowers, the type of fruit a species has first depends on whether you’re looking at a deciduous or evergreen tree.
- Acorns (oak)
- Catkins (willows)
- Cones (alder)
- Large fleshy fruits with seeds (e.g., crabapples, pears).
- Papery winged fruits of maple,
- Nuts (chestnut)
- Cones are the fruit of conifers and contain the seeds needed for reproduction
4. Fall: Colour me identified
For our last season of the year, we bring in colour again as a tree identical tool.
- From golden larch needles to vibrant orange ash leaves, fall gives a beautiful way to spot various trees.
- Timing of colour change
- Ash trees tend to change colour later in the fall compared to, say, mayday species.
- Keep in mind factors like moisture levels, latitude, and altitude also affect the timing of when leaves change colour. In drier years, leaves will turn faster compared to wetter years.
- When leaves drop
- As with when leaves change colour you can also identify Alberta trees from when leaves fall. Some species will drop theirs weeks before other species.
