Five Amazing Tree Facts with Archie the Arborist
Summary
TLDRIn this video, arborist Archie shares five fascinating facts about trees. Did you know deciduous trees reabsorb nutrients from fallen leaves through a process called nutrient cycling? Tree roots spread wider than they grow deep, often extending two to three times the canopy's length. Trees communicate with each other through a network called the 'wood wide web,' facilitated by mycorrhizal fungi. Trees don't heal like humans; they form permanent scars from wounds. Lastly, only one in a billion tree seeds survives to old age, emphasizing the need to protect and nurture them.
Takeaways
- 🌳 Trees are everywhere, with an estimated 3 trillion on Earth.
- 🍂 Deciduous trees lose their leaves in the fall, but only half the nutrients in the leaves are reabsorbed before they fall off.
- ♻️ The fallen leaves decompose and become part of the nutrient cycle, benefiting the tree again.
- 🍷 A tree's roots grow more outward than downward, extending 2-3 times the length of its canopy.
- 🌱 Tree roots mainly exist in the first foot and a half of soil, spreading far beyond the visible tree.
- 🌐 Trees communicate with each other through their roots with the help of mycorrhizal fungi, known as the 'wood wide web.'
- 💔 Trees don't heal like humans; they compartmentalize and scars from wounds become permanent.
- 🎰 Trees face incredible odds for survival—only one in a billion seeds grows to maturity.
- 🛡️ Trees in your yard need care to thrive and overcome challenges just like trees in the forest.
- 💚 Trees are complex, fascinating organisms that deserve care and attention, not just to be planted and forgotten.
Q & A
How many trees are estimated to be on Earth?
-There are an estimated 3 trillion trees on the face of the Earth.
What are the trees that lose their leaves during the fall called?
-The trees that lose their leaves during the fall are called deciduous trees.
What is the process by which trees reabsorb nutrients from fallen leaves?
-The process by which trees reabsorb nutrients from fallen leaves is called nutrient cycling.
How do tree roots typically grow in relation to the tree's canopy?
-Tree roots grow more outwards than downwards, often extending two to three times the length of the canopy.
What is the term used to describe the communication network between trees through their root systems?
-The term used to describe the communication network between trees through their root systems is the 'wood wide web'.
How do trees communicate with each other through their root systems?
-Trees communicate with each other through their root systems with the help of a special type of fungi called mycorrhizal fungi.
What is the significance of the 'wood wide web' in a forest ecosystem?
-The 'wood wide web' is significant as it allows trees to share information, exchange resources, and help defend against pests and other stressors.
How do trees respond to wounds or damage?
-Trees do not heal like humans; instead, they compartmentalize and form a permanent mark or scar when they receive a wound.
What is the survival rate of tree seeds to reach old age?
-The survival rate of tree seeds to reach old age is extremely low, with only one in every billion seeds making it to old age.
Why is it important to protect trees in our surroundings?
-It is important to protect trees in our surroundings because they have fought against the odds to survive and are complex organisms with their own stories.
What is the role of mycorrhizal fungi in the communication between trees?
-Mycorrhizal fungi play a crucial role in the communication between trees by facilitating the exchange of resources and information through the 'wood wide web'.

Highlights
There are an estimated 3 trillion trees on Earth.
Deciduous trees reabsorb half of the nutrients in their leaves before they fall.
Nutrient cycling is the process by which trees reabsorb nutrients from decomposing leaves.
Tree roots grow more laterally than vertically, often extending two to three times the canopy's length.
Trees communicate through a network called the 'wood wide web' facilitated by mycorrhizal fungi.
The 'wood wide web' allows trees to share information and resources.
Trees do not heal like humans; they compartmentalize wounds, which become permanent scars.
Only one in a billion tree seeds will reach old age, highlighting the importance of protecting trees.
Trees are complex organisms with their own stories, not just commodities to be planted and forgotten.
Trees should be left to their natural processes, such as nutrient cycling, for optimal health.
The majority of a tree's roots are in the top foot and a half of soil.
Mycorrhizal fungi play a crucial role in the communication and support network among trees.
Trees can extend their roots far beyond their canopy, showing their expansive underground networks.
The 'wood wide web' is a subterranean communication system that operates beneath our feet.
Trees can be affected by wounds, which can lead to permanent damage if not properly managed.
The survival rate of trees is extremely low, emphasizing the need for care and protection.
Each tree has a unique story, reflecting the fascinating complexity of these organisms.
The speaker's passion for trees is evident, aiming to inspire a similar appreciation in the audience.
Transcripts
today we're going to talk about trees
trees
they're amazing and they're everywhere
too there's an estimated 3
trillion trees on the face of the earth
they're in parks
they're in your backyard sometimes they
might even be in your own house
but there's a lot of cool things about
trees that you may not have heard of i'm
archie
i'm an arborist and today we're going to
talk about five awesome facts about
trees that you may not have heard of
during the fall some trees will lose
their leaves these are called deciduous
trees
but did you know that the tree will only
reabsorb half of the nutrients in the
leaves before they fall off
that means there's a lot of food left on
the ground these leaves will rot and
decompose and then get reabsorbed by the
tree
this process is called nutrient cycling
which means you should leave your leaves
for the tree the tree's form is shaped
like a wine glass tree roots grow out
more than they grow down
most of the trees roots exist in the
first foot and a half of soil
and they can extend two to three times
the length of the canopy
that means that this tree's roots can go
all the way out
to about right here trees talk to each
other
just listen
[Music]
okay well they don't talk to each other
but they do communicate through their
root systems with the help of a special
type of fungi called
mycorrhizal fungi they share information
exchange resources
and help defend against pests and other
stressors they may encounter we call
this the wood wide web and it's
happening under your feet
every time you walk through the forest
oh look a mushroom
[Music]
tell the trees i love them they'll get
it eventually
trees don't heal like we do they
compartmentalize
time a tree receives a wound it can
callous over and become a permanent mark
so this means anytime a tree sustains
damage like this pine right here
it can become a permanent scar this is
all the more reason to protect the trees
around us
and if you like hurting trees we can't
be friends
every mature tree that you see in the
woods has fought against the odds for
every billion
seeds a tree has dropped only one will
make it to old age
think of it like a forest lottery and
this guy right here
he's a winner like billionaire winner
but this means that the trees in your
yard
need as much help as they can get so
that they too can fight against the odds
trees are amazing and beautiful just
like you
but they're not commodities that we just
place in the ground and forget about
they're fascinating complex organisms
with their own stories to tell
my passion is for trees and i hope i've
given you a glimpse into how amazing
trees
really are
yes
