CAT OF THE WEEK
SAMMIE
Do you need a little “pick me up”?
Sammie is the purr-fect answer!
Sammie is a sweet and cuddly female
tabby, age 8 mos. She is fun and
very playful, but can also be mellow
and will love to fall asleep in your
arms. She gets along great with
other cats, too. Sammie will come
current on vaccines, healthy, and
neutered. Please call her foster mom
at 626-991-6619. You can see more pictures of Sammie at www.
lifelineforpets.org, the More Cats page. We would be so thankful
to get this sweetheart into a forever home by Thanksgiving!
Pet of the Week
Meadow came to the shelter as a nursing mom of
EIGHT puppies. They’ve all been adopted, and now
it’s Meadow’s turn to find a forever home and enjoy
her post-motherhood life! Meadow’s puppies were
beautiful, and they definitely got their looks from their
mom. This gorgeous two-year-old gal is a little shy in
her kennel, but comes out of her shell when she’s given
room to run and play. She’s particular about treats, but
if you give her the good stuff (hot dogs) she’ll love you.
All her kids have gone off to college, and Meadow is
ready to join a book club, take up cross-stitch, and live
her best life!
The adoption fee for dogs is $140. All dogs are spayed or neutered, microchipped, and
vaccinated before going to their new home.
New adopters will receive a complimentary health-and-wellness exam from VCA Animal
Hospitals, as well as a goody bag filled with information about how to care for your pet.
View photos of adoptable pets at pasadenahumane.org. Adoption hours are 11 a.m. to 4 p.m.
Sunday; 9 a.m. to 5 p.m. Tuesday through Friday; and 9 a.m. to 4 p.m. Saturday.
Pets may not be available for adoption and cannot be held for potential adopters by phone

Eucalyptus is a tree with a
mixed reputation. This stately
tree is renown for the “forest effect”
due to the high transpiration rate of its leaves.
According to one report, “In Sydney, a large gum
tree [eucalyptus] transpires up to 200 litres of water
a day. A well-maintained garden in Sydney will
transpire nearly twice the volume of water as the
total rainfall.”
The tree was included in my Guide to Wild Foods
book since it was so useful in its native Australia
by the Aboriginees: the leaves for various medicines
(mostly upper bronchial issues), the bark for infections
and many other uses, and even the little psyllid
bugs can be harvested and eaten like a backwoods
sugar. And the honey produced from eucalyptus
flowers is a dark almost-medicinal honey.
So is it wise to remove the eucalyptus trees and replace
them with natives? In order to fully grasp the
effects of eucalypti on the environment, let’s look at
its effect in other parts of the world.
Eucalyptus is a fast-growing tree. When you cut
them down, they will sprout right back up again.
Because of this, there have been major plantations
in various countries throughout the world from Europe
to China to Africa in order to supply the wood
for lumber, paper products, and firewood. If the
eucalyptus trees are planted in non-agricultural areas
where nothing else will grow, they survive quite
well. A eucalyptus tree in a plantation can be cut as
little as every four years.
Around the time that the U.S. was experiencing long
gas lines during the 1970s ”energy crisis,” many
countries around the world discovered that the eucalyptus
tree seemed like a miracle tree. It grew easily
anywhere, and could be regularly harvested for
fuel wood, building materials, and pulp for paper.
It was also a financial boom to the public and private
businesses in various countries who grew these
plantations. Today, eucalyptus is the number one
tree planted in plantations around the world. With
so many undeniable benefits, what could go wrong?
Over the last 30 to 40 years, countless business, governmental,
and academic studies have been done to
weigh the pros and cons of the largescale use of the
eucalyptus tree. I’ve spent time over the last year
compiling hard data on the eucalyptus tree.
There were very real worries about deforestation
and desertification that began in the 1980s. Eucalyptus
trees, with its obvious economic benefits,
were planted in ever-greater numbers. Today we
can analyze the ecological effects of over 30 years of
eucalyptus plantations.
Because the eucalyptus tree is such a great transpirer,
it follows that it generally consumes far more
water than other native or non-native trees. In fact,
one of the stated reasons that eucalyptus is planted
in certain countries is to dry up swamps and wet areas,
either for development or because the wet area
was believed to be a source of malaria. The deep
roots of eucalyptus, and their extensive network of
small surface roots, has been noted to extend deep
to the water table.
Although a eucalyptus plantation does very well in
dry areas where nothing else is growing, in areas as
diverse as China, Ethiopia, Vietnam, etc, local villagers
of these diverse places have noted that their
water wells run dry. In fact, this seems to be one
of the main objections to eucalyptus plantations:
it dries up the local sources since it generally consumes
more water than is received by rain in any
given area, which then means there is far less water
for agricultural crops and orchards.
In studies done to determine if the leaf drop from
eucalyptus is "allelopathic" (exuding soil toxins),
various plants grown in a mixture of eucalyptus
mulch and soil have exhibited a germination rate as
low as 3%, compared to normal rates of germination
with an oak mulch.
Another argument against the eucalyptus plantations
is that there is a great depletion of soil nutrients.
In general, eucapytus take up more nutrients
(and water) from the soil than other native or non-
native trees because they are fast-growing. And, in
theory, if all the leafy matter was left on the ground
(as opposed to cleaning it up), those nutrients
would degrade and enrich the soil. But unfortunately,
eucalyptus mulch takes a very long time to be
degraded by bacteria and fungus due to its oils, and
so in actual practice, the soils around eucalyptus
tend to be very desert-like due to the unavailability
of nutrients. [Source: The Effect of Eucalyptus and
Oak Leaf Extract on California Native Plants, Kam
Watson, UC Berkley]
This effect results in the lack of biodiversity and
understory that is commonly observed under and
around eucalyptus trees, in stark contrast to native
forests.
One study was also done with soil under the eucalyptus
trees, along with a soil sample not influenced
by eucalyptus. Soil samples from under eucalyptus
trees proved to be less able to absorb water.
This meant that though eucalyptus trees have been
planted in areas to reduce runoff and flooding, this
result is not usually successful because of the effect
of the tree’s oil on the soil. These same results have
been documented in eucalyptus plantations in China,
Kenya, Ethiopia, Vietnam, and other sites.
Kenya Forest Service has published guidelines, basically
aimed at promoting eucalyptus plantations
in the country, called “A Guide to On-Farm Eucalyptus
Growing in Kenya”, December 2009. They
advise not growing eucalyptus in wetlands and
marshy areas, and riparian areas. They advise not
growing eucalyptus closer than 30 meters from rivers,
and ideally 50 meters, so that the trees do not
adversely interfere with the water source.
They add that other areas where eucalyptus should
not be planted include around lakes, ponds,
swamps, estuary and any other body of standing
water. They advice that eucalyptus not be planted
closer than 50 meters to farm lands, and other measures.
In other words, even those who are pro-eucalyptus
recognize the adverse effects of eucalyptus on
the environment, and offer ways to minimize those
effects.
Though there are medicinal benefits to the eucalyptus
tree, there are better native trees to plant which
provide the same benefit.
