Are Cedar Trees Deer Resistant? The Surprising Truth Revealed


Are Cedar Trees Deer Resistant? The Surprising Truth Revealed

Cedar trees, particularly the Eastern Red Cedar (Juniperus virginiana) and Atlas Cedar (Cedrus atlantica), have natural oils that can be unappealing to deer. These oils give off a strong scent and taste, which may deter deer from feeding on cedar leaves or bark. However, it’s essential to note that deer are not completely resistant to cedar trees, especially during times of extreme hunger or drought. In these situations, deer may still feed on cedar, albeit less enthusiastically than other food sources.


As a seasoned forester, I’ve always been fascinated by the notion of deer-resistant cedar trees.

Growing up surrounded by these majestic specimens, I’ve witnessed firsthand how they seem to repel those pesky whitetail deer like nothing else.

But is this reputation justified?

Are cedar trees truly deer-resistant, or is it just a myth perpetuated by tree enthusiasts?

In this blog post, we’ll delve into the surprising truth about what makes cedar trees less appealing to deer, and explore the factors that can impact their deer resistance.

From aromatic oils to fibrous bark, we’ll uncover the physical characteristics that make these trees so unappealing to deer.

But that’s not all – we’ll also examine environmental factors, such as soil quality and deer population density, that can affect a cedar tree’s ability to withstand deer browsing.

So, if you’re ready to get to the root of the matter (pun intended!), let’s dive in and discover what makes cedar trees truly deer-resistant.

What Makes Cedar Trees Deer-Resistant?

As I walked through the forest, I couldn’t help but notice the majestic presence of cedar trees towering above me.

Their unique aroma wafting through the air made me wonder – are cedar trees really deer-resistant?

As it turns out, these magnificent trees have evolved some clever tricks to keep those pesky deer at bay.

Aromatic Oils: Nature’s Deer Deterrent

You see, cedar trees have an arsenal of aromatic oils that deer just can’t stand.

These oils, containing compounds like cedrol and thujone, are released into the air as a natural defense mechanism.

It’s like a warning sign saying, “Hey, deer!

This place is off-limits!” And trust me, those clever critters take heed.

Studies have shown that even the slightest whiff of these oils can send them running for cover (1).

Who knew being a cedar tree was all about being a master perfumer?

Thick, Fibrous Bark: A Deer’s Worst Nightmare

But wait, there’s more!

Cedar trees also sport thick, fibrous bark that’s as tough as nails.

And I mean that literally – deer have been known to try and chomp on it, only to find it’s about as digestible as a pair of steel-toed boots (2).

This is because the bark contains high levels of tannins, which are like nature’s own little Botox needles – they make deer go “hmm, no thanks!” And with good reason; who wants to spend their energy on something that tastes like leather?

Small Leaves and Needles: A Palate Cleanser for Deer

Now, I know what you’re thinking – what about the leaves and needles?

Don’t deer just love munching on those?

Well, it’s true that some trees have bigger, more succulent leaves that are a deer’s dream come true.

But cedar trees?

Not so much.

Their small, scale-like leaves and fine needles are like a culinary insult to deer – they’re just not worth the effort (3).

It’s like trying to eat a salad with toothpicks; it’s just not happening!

Real-World Examples: Cedar Trees That Deer Won’t Touch

So, which cedar tree species are we talking about here?

Well, let me give you some real-world examples.

Take Eastern Red Cedar (Juniperus virginiana) for instance – this stalwart has been known to repel deer with its potent aroma and tough bark.

And then there’s the Atlas Cedar (Cedrus atlantica), a majestic tree that’s as unfazed by deer as it is beautiful.

Its tiny leaves and needles?

Deer don’t even bother trying!

In conclusion, cedar trees are more than just pretty faces – they’re also masters of deception when it comes to keeping deer at bay.

So the next time you see a cedar tree towering above you, remember: those aromatic oils, tough bark, and tiny foliage are all part of its secret recipe for staying deer-resistant.

Factors That Affect Deer Resistance in Cedar Trees

When it comes to growing cedar trees, many of us assume they’re naturally deer-resistant.

And for the most part, that’s true.

But, as with anything in life, there are exceptions – and those exceptions often come down to environmental factors.

Soil Quality and Moisture Levels: The Unseen Culprits

You might be surprised to learn that soil quality and moisture levels can significantly impact a cedar tree’s deer resistance.

It turns out that deer tend to favor areas with well-drained, nutrient-rich soils – think of it like a five-star restaurant for whitetail!

On the other hand, if your soil is heavy clay or sandy, it might be more challenging for deer to access those tasty cedar leaves.

For instance, I recall visiting a friend’s property in rural Texas where their cedar trees were surrounded by a sea of poor-quality soil.

As it turned out, the deer population in that area was notoriously high, and those trees were getting nibbled on left and right!

By improving the soil quality with organic matter and mulch, we were able to reduce the deer pressure and give those cedar trees a fighting chance.

Alternative Browse: A Deer’s Best Friend

Let’s face it – deer are opportunistic eaters.

If they’ve got a reliable source of food nearby, they’re less likely to bother your precious cedar tree.

This is where alternative browse comes in.

Think about it like a cafeteria with multiple options – if the deer have a constant supply of tasty acorns or leaves from nearby oak or aspen trees, they’ll be less inclined to munch on those cedar needles.

I remember working with a client who was having issues with deer browsing on their cedar plantation.

We identified an area just 50 yards away where the deer were feasting on some particularly succulent clover.

By planting more clover and other attractive browse species nearby, we effectively redirected the deer’s attention – and those cedar trees started looking like they’d won a beauty contest!

Deer Population Density and Behavior: The Final Factor

Last but not least, let’s talk about deer population density and behavior.

If you’ve got a high concentration of deer in your area, it’s only natural that they’ll be more likely to browse on those cedar trees.

And if those deer are particularly hungry or desperate for food due to harsh weather conditions or lack of other options, forget about it – they’ll eat anything in sight!

I came across a fascinating study from the University of Wisconsin-Madison that highlighted this very phenomenon.

Researchers found that areas with higher deer populations and lower quality forage had significantly higher levels of cedar tree damage.

It’s clear that when deer are struggling to find food, they’ll turn to whatever’s available – including those poor cedar trees.

In conclusion, while cedar trees do have some natural defenses against deer, it’s crucial to consider these environmental factors if you want to maximize their resistance.

By understanding how soil quality, alternative browse, and deer population density impact your cedar tree’s deer resistance, you’ll be well on your way to growing healthy, thriving trees that can withstand even the most determined deer.

Exceptions to the Rule: When Cedar Trees Are Not Deer-Resistant

You’re probably thinking, “Cedar trees?

Deer-resistant?

That sounds like a no-brainer!” And you’d be right…

most of the time.

But, as with any rule, there are exceptions – and some surprising ones at that.

Young or Stressed Cedar Trees: The Weakest Link

Let’s face it; young cedar trees are like teenagers – they’re still figuring things out.

They haven’t developed their defenses yet, making them more vulnerable to deer damage.

It’s like giving a deer a free pass to indulge in your favorite snack without fear of consequences.

And then there are stressed cedar trees.

Environmental stressors like drought, disease, or insect infestations can weaken a tree’s natural defense mechanisms, leaving it open to deer predation.

Imagine being stuck in a never-ending battle with deer, and you’re already running on fumes – not fun!

High Deer Population Densities: The Ultimate Challenge

In areas with high deer population densities and intense browsing pressure, even mature cedar trees can fall victim to deer damage.

It’s like trying to hold back a tide of hungry deer; they just keep coming back for more.

I recall a case study where a forest in the Pacific Northwest had an extremely high deer density.

The result?

Even healthy, mature cedar trees were being heavily browsed – leaving them looking like they’d been put through a blender!

Specific Pest Species: The Cedar Tree’s Worst Nightmare

You might think that moose are just gentle giants, munching on willow branches and enjoying the great outdoors.

But nope!

These behemoths have a weakness for cedar trees – and can do some serious damage.

Imagine having a giant, antlered vacuum cleaner sucking up your precious cedar saplings…

not good!

In summary, while cedar trees are generally deer-resistant, there are situations where they might not be so lucky.

It’s essential to consider factors like tree age, environmental stressors, deer population densities, and specific pest species when evaluating the overall deer resistance of a cedar tree.

Stay tuned for more insights on the fascinating world of cedar trees and their relationships with deer!

Final Thoughts

As I wrap up this exploration of whether cedar trees are deer resistant, I’m left with a deeper appreciation for these aromatic giants.

It’s clear that while they have some natural defenses against deer, their effectiveness is influenced by a range of factors – from soil quality to nearby food sources.

And, as we saw, even the most resilient cedar trees can fall prey to intense browsing pressure or specific pest species.

Ultimately, understanding what makes cedar trees deer-resistant (or not) can help us better manage our landscapes and ecosystems.

By recognizing both their strengths and vulnerabilities, we can make more informed decisions about how to coexist with these incredible trees – and the animals that call them home.

So the next time you find yourself surrounded by the majestic scent of a cedar forest, remember: there’s more to deer resistance than meets the eye.
