Hinsdale has a long history of maintaining and fostering
our Village's natural beauty. The Village has combated the
Dutch elm disease(DED) since it arrived 50 years ago. There
is an on-going elm maintenance program that encompasses
early detection, task pruning to remove infected limbs as
warranted, timely removal of infected trees, and inoculation
of healthy trees with a preventative fungicide.

Exactly one month after state officials announced
the first emerald ash borer (Agrilus planipennis)
infestation in Illinois, officials revealed the pest
has been found in Wilmette, a suburb north of Chicago.
Also, Wilmette village foresters have found 16 trees
in a five-block area with symptoms of emerald ash
borer (EAB) infestation. On June 13, 2006 the Illinois
Department of Agriculture (IDOA) announced that a
beetle found in the yard of a Kane County home east
of Lily Lake was EAB. The Morton Arboretum was out
in front as an advocate for developing prevention
and readiness plans to prepare for the inevitable.
Officials believe the borer arrived in Illinois
on ash firewood transported from a quarantined area
in Michigan. Firewood transport is the primary means
of introducing pests into new geographic areas. EAB
threatens to destroy one-fifth of all Chicago-area
trees, which are ash, and could destroy the 130-million
ash trees in Illinois. For more information, please
go to The
Morton Arboretum - Emerald Ash Borer Section or
go to The Morton
Arboretum website.
On February 22, 2011, the Illinois Department of
Agriculture (IDOA) confirmed an infestation of Emerald
Ash Borer (EAB) in Hinsdale. EAB is a small, metallic
green beetle native to Asia. Since EAB was discovered
in Michigan in 2002, more than 20 million ash trees
have been lost. The Village of Hinsdale has an estimated
15,500 trees on public property. Read more

letter about the Emerald Ash Borer.

The Village of Hinsdale is continually updating its forestry
program. The goal is to establish and maintain a safe, healthy,
energy efficient and aesthetically attractive community
forest, using cost effective and professional management
techniques.
The forestry program is apart of the Department of Public
Services. Its objective is to manage healthy, suitable and
vigorous trees on parkways and Village properties, and provide
current information and expertise to homeowners regarding
both public and private property trees.

There have been reports of coyotes in forested sites around
Hinsdale. According to the DuPage County Forest Preserve (DCFP),
there is no need to be frightened. There has been no reported
incidents of coyotes biting a human. However, residents should
avoid making food sources available to these or other unwanted
animal visitors. Keep pet food and watering dishes inside.
Keep garbage cans indoors or secure. Do not allow spillage
to accumulate around bird feeders. For further information

CHAMPAIGN, IL (May 3, 2006) - Many homeowners choose to mulch
because they enjoy the well-cared-for look it gives their
landscape. But, they may not realize they are also providing
many benefits for their trees. With mulch the result can be
a better growing environment for trees and their roots.
-----
Homeowners
should be aware that, generally, the root system of a tree
spreads out not down. "The roots of most trees extend out
a significant distance from the trunk. Most of the fine absorbing
roots of trees are located within inches of the soil surface,"
says Jim Skiera, Executive Director of the International Society
of Arboriculture. These shallow roots are essential for taking
up water and minerals for trees, and they require oxygen to
survive. A thin layer of mulch, spread widely, can provide
a healthier environment where these roots grow.
Mulch
Benefits
Properly
applied mulch provides many benefits to the health of a tree.
Unlike trees growing in a forested environment, urban trees
are not typically planted in an optimal environment for root
growth and mineral uptake. Typically, urban environments are
harsher with poor soil conditions and large fluctuations in
moisture and temperature. Applying mulch can help reduce the
stress of such conditions through these benefits:
- Helping
to maintain soil moisture with less evaporation
- Reducing
the number of weeds
- Providing
insulation by keeping soil cooler in the summer and warmer
in the winter
- Protecting
from damage caused by lawn equipment such as weed-eaters
and lawn mowers
- Improving
soil fertility, aeration, and drainage
Organic
or Inorganic
Mulches are either organic or inorganic material mixtures
that are placed over the soil surface around the base of a
tree. Mixtures consisting of various types of stone, rock,
pulverized rubber, and other materials are labeled as inorganic.
Because these types of mixtures do not decompose, they need
replenishing less often. However, this also means they do
not improve soil structure, provide nutrients, or add organic
materials to the soil. Inorganic mulches do still provide
other benefits such as insulation, and protection.
Organic mulches consist of wood chips, pine needles, bark,
leaves, and other products derived from plants. These mulches
decompose, thus are very beneficial in improving soil quality
by replenishing nutrients. They do however require more maintenance
because decomposition creates the need to replenish more often.

Woodchips here.
Mulching
Do's and Don'ts
In order for mulch to be beneficial, it must be applied correctly.
"All things in moderation should be a homeowner's mulching
motto," says Skiera. "As beneficial as mulch is, too much
can be harmful in more ways than one." Too much mulch can
create excess moisture that may lead to root rot. Other problems
created by over mulching include insect and disease problems,
weed growth, sour smelling planting beds, and chewing rodents.
To ensure the health of your trees and plants, follow these
practical mulching tips to landscape like the pros:
- Thin
is better. Apply a 2 to 4-inch layer of mulch unless a
drainage problems exist then a thinner layer is recommended.
Do not add mulch if there is already a sufficient layer.
Instead, rake the old mulch to break up any matted layers
and refresh the appearance.
- No
volcano mulching. Avoid placing mulch against the tree
trunks. If mulch is already piled against the stems or
tree trunks, pull it back several inches so that the base
of the trunk and the root crown are exposed.
- Mulch
Wide. Mulch out to the tree's drip line or beyond if possible.

Champaign,
IL (January 16, 2006) - The tree-filled landscapes of winter
can be mistakenly thought to be asleep. Wintering trees
are not sleeping; they are simply still - counting the days
until spring. Only then will it be apparent whether the
tree has saved enough resources to respond to the new season
of growth.
Winter
is a difficult time for trees which must stand alone against
all circumstances that the season can generate. Trees have
some internal methods of protection. Most of the growing
points in the tree are protected inside jackets called buds,
and food reserves are carefully conserved for the coming
needs of spring. Also water continues to move through the
tree until it freezes. However, these protective stages
may breed other problems. For example, creatures needing
a meal may chew and nibble on the resting buds and twigs.
What
can you do to help your valuable trees? A few things can
help a tree be more efficient and effective in surviving
the winter and thriving in spring.
These small winter investments can pay off in a large way,
yielding healthy and structurally sound trees.
The
"Critical Six" things to do for your tree this
winter are:
- Add
a thin layer of composted organic mulch to blanket the
soil surface.
Mulch protects and conserves tree resources and recycles
valuable materials.
- Properly
wrap new trees that have not developed a corky bark and
could easily be damaged. Mechanical injury from the environment,
including chewing and rubbing by animals, must be prevented.
- Remove
or correct clearly visible structural faults and deadwood.
Try to make small pruning cuts that minimize the exposure
of the central heartwood core on branches.
- Perform
limited greenwood pruning of declining and poorly placed
branches.
Pruning should conserve as many living branches as possible,
with only a few selective cuts.
- Fertilize
with elements needed in small quantities. Essential elements
added over a mulch layer will help provide a healthy soil
environment for root growth.
- Water
where soils and trees are cool but not frozen, and where
there has been little precipitation. Winter droughts need
treatment with waters the same as summer droughts. However,
it is easy to over water in winter, so be careful.
Invest
in great trees by helping them over a difficult time. For
trees, wonderful springs come from well-tended winters.
