Needs Your Help!
Cantigny is proud to have so many different types of
trees along the Hiking Trail and they need your help to
name each one. A special map has been made showing
where the trees are located and each tree has a
numbered tag attached to it.
Using the descriptions and pictures of the trees in this guide,
and the special map, list the names of each tree next to
their numbers from the map.
Answer key can be found on the inside back cover.

Before you head out to help identify some of
the trees along Cantigny’s Hiking Trail, let’s
take a minute to learn about the different
types of trees and how they grow.
Anatomy of a Tree
The outer bark is the tree’s protection from
the outside world. Continually renewed from
within, it helps keep out moisture in the rain, and
prevents the tree from losing moisture when the air
is dry. It insulates against cold and heat and wards
off insect enemies.

Inside of a Tree Trunk

E D
The inner bark, or “phloem”, is pipeline
C
B through which food is passed to the rest of the
tree. It lives for only a short time, then dies and turns to cork to become part of
the protective outer bark.
The cambium cell layer is the growing part of the trunk. It annually
produces new bark and new wood in response to hormones that pass
down through the phloem with food from the leaves. These hormones, called
“auxins”, stimulate growth in cells. Auxins are produced by leaf buds at the
ends of branches as soon as they start growing in spring.
C
Sapwood is the tree’s pipeline for water moving up to the leaves.
Sapwood is new wood. As newer rings of sapwood are laid down, inner
cells lose their vitality and turn to heartwood.
D
Heartwood is the central, supporting pillar of the tree. Although dead,
it will not decay or lose strength while the outer layers are intact. A
composite of hollow, needlelike cellulose fibers bound together by a chemical
glue called lignin, it is in many ways as strong as steel. A piece 12” long and
1” by 2” in cross section set vertically can support a weight of twenty tons!
E
Leaves Make Food for the Tree
And this tells us much about their shapes. For example, the narrow needles of a
Douglasfir can expose as much as three acres of chlorophyll surface to the sun.
The lobes, leaflets and jagged edges of many broad leaves have their uses, too.
They help evaporate the water used in food-building, reduce wind resistance — even
provide “drip tips” to shed rain that, left standing, could decay the leaf.
Tree Terms
Branches: These arms of the tree hold the leaves or needles up to receive the sun’s energy.
Cambium Cell: Is the growing part of the tree trunk.
Coniferous: Trees that have small waxy leaves, sometimes needles, which are usually
kept all year.
Deciduous: Trees which shed their leaves or fruit at seasonal intervals.
Gums: The trees sap contains food made by photosynthesis and other minerals and
nutrients. Sticky gums in the sap are used by the tree to protect it from invading
insects and wounds that cut through the bark. People use tree gums for many useful
products, such as adhesives, drying agents in paint and ink, and ingredients in soap
and cough syrup, to name a few.
Leaves or needles: The miracle of photosynthesis takes place here. Air and water come
together with energy from the sun. Food is the end product, which the tree uses to grow
bigger and reproduce. Oxygen is a welcome by-product of the process. Leaves or
needles also help filter pollutants, shelter wildlife and shade the homes of fish and people.
Palmate(ly): Leaves resembling fingers on a hand.
Pinnate(ly): Leaves that resemble feathers.
Roots: Serving as both anchor and sponge, the roots help to stabilize the tree and to
soak up water and nutrients for the tree to use in photosynthesis. Roots also serve as
a storage area for sugars made through photosynthesis, and help hold
precious forest soils in place.
Trunk: The woody trunk is what makes a plant a tree. It holds the
branches and leaves up to the sun. Wood in the trunk is used for
countless wood and paper products that people use every day. Tree
trunks also provide homes for animals.
Whorl(ed): Three or more leaves originating from the same point.

Recycling:
It starts with you!
Step 4.
The pulp is washed, refined
and cleaned, then turned to
slush with a beater. Because
there is a limit to the number
of times paper fibers can
be recycled before they
become weakened, new
wood fiber is often mixed
with recycled paper to
make new paper products.
Why is recycling so important? Can tossing
your used paper in a recycling bin instead of
the garbage really make much difference?
The answer is yes. Recycled paper supplies
more than 37 percent of the raw material
used to make new paper products. Recycling
paper also helps our community by diverting
it from landfills. So, every bit of paper
used for recycling helps improve tomorrow’s
environment today.
How does paper
recycling work?
Step 1.
After collection,
recovered
paper is
transported
to a recycling
center or
Material
Recovery Facility
(MRF), where contaminants such as plastics, glass,
aluminum, paper clips and staples are removed.
Step 5.
Dyes, coatings and other
additives are mixed into the pulp
slush to refine it, and then the mixture is pumped
onto a large moving screen.
Step 6.
As the pulp moves down the screen, water drains
away and leaves behind a paper sheet also known
as “web.” Giant rollers squeeze out still more water
to ensure that the paper is uniformly smooth and
thick. Finally, heated rollers evaporate any water
remaining in the paper.
Step 7.
The finished paper is wound into large rolls, which
can be up to 30 feet wide and weigh close
to 25 tons. Now the new paper is ready
for use in your school or community.
Step 2.
Once the recovered paper is free of contaminants,
it is then baled and transported to a paper mill where
the recycling and paper making process begins.
Step 3.
Recovered paper is shredded and mixed with
water to make a pulp. Printed papers, such as
newspapers and magazines, are de-inked
in a flotation device that helps
the ink separate from the
pulp. Air bubbles are blown
into the mixture, and the
ink attaches to the bubbles
and rises to the top, where
it is skimmed off, leaving the
pulp ink-free.
Recycle!
