If you’ve been thinking about landscaping your yard, you should know things have
changed. The climate is warming so quickly that one organization has changed the
plant hardiness zone map. That’s the little map you sometimes see on the back of
seed packets. Lester Graham reports… you might want to check out the new map
before you spend hundreds of dollars on a tree that might not live long in your
warmer zone:


You know, I’ve talked to a lot of gardeners and homeowners who do their own
landscaping about this plant hardiness zone map change, and at first they’re
kind of astounded. The growing zones are changing? Because it’s getting warmer?


But then, they sort of pause and think for a moment… and usually say something like,
“That makes sense.”


The United States Department of Agriculture issues the plant hardiness zone map.
It’s basically a map of the annual average low temperatures that helps folks figure
out what they can plant and expect to survive. But the USDA hasn’t updated its map
since 1990.


The spokesman at the National Arbor Day Foundation, Woody Nelson – I kid you not,
the Arbor Day guy’s name is Woody – Woody says his organization issued a new
map because it really needed to be updated:


“You know, people were asking us to help out, you know, ‘This old USDA map just doesn’t
seem to work for us anymore. I don’t think it’s accurate. What can you do to help?’
So we took it upon ourselves to give tree-planters the most up-to-date information
that we could.”


So the National Arbor Day Foundation looked at the low temperature data gathered
by the National Oceanic and Atmospheric Administration since 1990, and the people
were right: things are warming up:


“And over that 15-year span that we used, much of the country had warmed a full
hardiness zone.”


And there’s a ten degree difference from one zone to the next. It shows a real on-
the-ground trend.


Richard Andres is with Tantre Farm. They grow organic produce for farmers’
markets like this one in Michigan. Andres didn’t know about the new Arbor Day
Hardiness Zone map, but it makes sense to him. He says he’s seeing more
extremes:


“You know, last winter was unusually warm. The winter before, unusually warm.
So, we really didn’t even get a decent freeze. We had a huge amount of bugs the
following spring. So we are noticing more extremes.”


But a farmer or gardener can adjust things for annual plants. Long term, you’re
probably wondering whether you can now plant that dogwood or whether you
should plant that spruce from up north.

Phil Walsh sells a lot of trees at Lodi Farms nursery. He knew about the new Arbor
Day Hardiness Zone map. But, he says there’s a lot more to think about than just
the annual average low temperature when you’re thinking about planting:


“Cold is not the only, or really the most, important factor when determining plant
hardiness. Questions like soil: is it well-drained; is it not; is it wet; is it dry; is it acid
or is it alkaline; do you have wind; do you have shade? Questions like this: is it high
in organic material or low in organic material? These tend to have more impact on
whether or not plants survive than strictly the zone rating.”


Walsh says the trees are pretty tough, and most of them can adapt:


“Yes, things have warmed up over the last 15 years and they may well continue or it may change and it may go down. Pick a good, hardy plant that’s well-suited for your soil
and typically one that’s native here, that’s gone through these temperature changes
in the past and I don’t expect anybody’s going to have any problems with them.”


That’s not to say that every kind of tree is taking this in stride. For example, black
spruce trees adapted to Canadian and upper New England cold might not be such a
good choice as far south as it’s been grown in the past.


Woody Nelson at the National Arbor Day Foundation says trees native to the North
are starting to be affected by the warming climate:


“There’s a whole lot of white pines that have been planted in Georgia, in the South
as a nice landscape tree over the years. And now those white pines are coming
under a little bit of stress. The native lodge pole pines, the native loblolly pines in the
deep South, again native species are something that we want to promote and stick
with.”


So, the basic rule is: if the plant hardiness zone map has shifted one growing zone
warmer in just 15 years, you’ll probably want to stick to trees native to your area, or
from just a little south of you just in case this warming trend sticks around for a while.

Raw Pet Food Junkies

Reports of contaminated pet foods,
causing illness and even death, have pet owners
scurrying for safe alternatives to feed their
animals. Joyce Kryszak reports that’s opening
a door of opportunity for advocates of holistic
pet feeding:


“This is Woody.”


You’d never guess that Woody is 11 to look at her. The mid-sized
mixed breed is as spry as a puppy. And as hungry as one, too, since we
rudely showed up at her dinner time. But Woody’s owner, Alexandra
Murphy says this is a good time to get a peek at Woody’s menu.


“Today, for breakfast she got two chicken wings, and she got a couple
of chicken gizzards. She’s going to have that for dinner and before she goes to bed tonight she’s going to have two
to three ounces of ground up veggies.”


Murphy says she’s a “raw feeder.” That means her dog Woody and 11-year-old cat, TJ, only eat raw meat and veggies. No kibble food from a
bag for these guys:


“Okay, I start with vegetables that I like. I like broccoli a lot because
nutritionally, it’s a very dense food.”


Murphy says she began feeding raw about seven
years ago after a doing a lot of research. And after getting a lot of
flack from fellow pet owners and skeptical veterinarians:


“I’m looking to give them something that is as close to what their species would get in nature.
I know my dog’s not a wolf. But I also know that pet food has only been made for the last fifty years. They
didn’t go through such a drastic change, that all of a sudden all of
this real food is going to make them sick.”

Murphy is certainly not alone in her passion for holistic feeding.
There’s almost a cult following of pet owners who spend hours grinding
or cooking their own pet food. And there are some vets out there who
whole-heartily support them.


Cynthia Lankenau is a holistic veterinarian. Lankenau says commercial
foods have never been good for pets – even before the tainted food
scare. She says dogs and cats simply can’t digest grain very well.
But grain is the main ingredient in most commercial pet foods. So, why
do most vets still promote them? For starters, Lankenau says it was a
major pet food-maker that taught nutrition at her vet school:


“Yeah, just about any vet that graduates is truly, honestly, strongly
believing that that’s the best nutrition that’s available. But we were
brainwashed.”


But some vets are breaking free of traditional training. Jim Albert is
a small animal veterinarian and a vet for the Buffalo, New York zoo.
Albert’s still not sure how he feels about raw meat diets for pets. But
Albert admits that the nutritional requirements are quite similar, no
matter the size of the canine or the cat.


“Small animals have small canine teeth for a reason, dogs and
cats. And those were typically used to apprehend and hold prey, so I
guess you could make the argument that meat should certainly constitute
a percentage of their diet.”


Albert concedes there are plenty of good options out there. And
there’s good reason for people to be exploring those options. Albert
says he’s treated half a dozen pets that became very sick from tainted
commercial foods. And he says that has even some of his busiest
clients are trading in their processed food and making their own in
food processors.


“It certainly wasn’t feasible for a lot of our clients in the past, but
I think they’re taking these kind of matters into their own hands.”


Back in Alexandra Murphy’s kitchen it’s pretty obvious how much work
homemade pet food can be. Murphy says her pets are worth it. But she
admits making homemade pet food isn’t for everyone:


“Although I love doing this, I would say to someone, if you’re the
kind of person who says, ‘Oh, I really don’t want to have to do this,
can I cut this corner, can I cut that corner,’ you may not be cut out
for it. Because if you can’t do it right, you shouldn’t be doing it at
all.”


She says one of the best ways to find out is to find a good mentor.
And they are out there. You can find them by calling a local holistic
vet. Or, go online and you’ll find packs of natural feeders who love
to share their philosophies… and their recipes.
