ENTS,

Greetings from Germany! This is my first message to the entstrees
group. Or actually second, as I tried to send this yesterday but I
think I did something wrong... Sorry, if this comes twice. I hope this
forum is open for forest/tree lovers outside of North America as well;
I have been in this mailing list already couple of weeks. As here in
Europe there are only very few tiny remnants of old growth forests, I
have done some hiking trips to other parts of the world, including USA
and Canada, and love to read about your great old growth forests and
trees.

What encouraged me to write my first message... I read from this
mailing list that Liriodendron puts now first leaves in the Smokies,
and I saw yesterday (April 2) here in eastern Germany (latitude of 51
degrees) the first tulip tree leaves! The species is planted quite
often here.

Kouta,

Welcome aboard...I am doing a study with Liriodendron and I would love
to get some data from Germany regarding maximum height, CBH, age,
etc. Do you have access to any numbers like that?
Also, I am interested in first leaf and first flower times in other
areas of the world outside the U.S.
Would be happy to share data with you..

Than you Kouta. As far as I know, there are no native populations of
Liriodendron in Germany. Is this correct? Has it become naturalized
anywhere?

The yellow poplar leaves down here are different than what I see in
the mountains or even the piedmont for that matter. The leaves are
smaller and the "keystone" shape seems to be less pronounced. I would
say our leaves to be more "squarish" if there is such a word. But I
see that smaller leaf shape in a number of species that are
widespread. Red Maples especially. The maple leaves here have very
indestinct lobes almost round while those in the mountains are twice
the size and have a destinctive maple leaf shape. White oaks too, the
few we have down here are generally with shallow sinuses and lobes and
those above the fall line having very deep sinuses.

Gary, Did you look at the photo I posted the other day? Do you have
photos of all three? Also, what Will posted is so true. Many times I
see leaves that are similar to a species with small differences. I
guess these may be caused by several factors, location, climate,
pollination, genectics, etc? Curious Larry

From: "Gary A. Beluzo"

Larry,

Hmmm...variation in leaf morphology. Leaves on any particular tree
can vary for a number of reasons. For example, the leaves on the
lower limbs that are in the shade tend to be larger, darker from a
higher concentration of chlorophyll, higher dendricity (a unitless
value indicating the amount of deviation from circular), while the
leaves at the top of the tree tend to be smaller, thinner, lighter in
color, and lower dendricity. This of course has to do with light
availablilty. Some trees vary the color of their leaves based on the
proximity to the top, the accessory colors acting as "sunscreen".
This is an interesting topic; perhaps we can start a new thread about
it.

Gary, Excellent! Ed has so much going on maybe we can talk him in

Igneous Pine, he would consider adding leaf morphology to the Webpage!
I'll see about photographing Tulip leaves in several locations. For
comparison purpose, I'd like to know the difference in appearance.
Tulip Trees have always been one of my favorites. Found this link

Gary;

I am in coastal Georgia which shares many species with Fla to the
south and the Carolinas to the north. I didn't realize there where
subspecies of Lirodendron, so I really can't answer the question in
regards to Yellow Poplar. Our Yellow poplars grow in springheads like
Florida's so I would guess they would be more like Floridas and our
soils are lighter like Floridas rather than the heavier soils of the
western Gulf Coast. I will go out an photograph some of the leaves and
maybe you can determine where they fall. I am not a taxonomist and
sometimes really wonder, as Larry and others have posted, how much is
actually a subspecies and what is climate or soils driven.

South Georgia Red Maple - non glaucous April 05, 2008

Trees such as the Post oak are vastly different down here from those of the
Piedmont and mountains and even locally trees like Live Oaks should
tremendous variation depending on the soils and exposure. We have one
called the Sand Live Oak (Q. geminata) that is very common with small
strongly revolute leaves that grow on the sandhills and I really
wonder if they are truly a different species from Q. virginiana with
leaves three times wider and longer which grow on the better soils.
Also the maritime Live Oak (Q. maritima) which grows on the barrier
islands adjacent to the dunes is not more an adaptation rather than a
true species. We have the same thing with red cedar (J. virginiana) as
opposed to the southern red cedar (J. silicola) which I honestly can't
tell apart in many instances.

Gary,

I haven't seen (or read about) naturalized Liriodenron anywhere in
Europe, although it grows well here. In Central Europe there are two
extensively naturalized tree species from your area: Quercus rubra and
Robinia pseudoacacia.

Q. rubra is a common park tree and is planted also for timber. There
is often plentiful regeneration on the forest floor, and the species
has become one of the commonest trees in broadleaf forests.

Robinia is planted here in parks and gardens, and in southern Europe
also for timber. Its natural pest are missing in Europe; this and the
nitrogen fixing bacteria of its roots give it a competition advantage
over the natural tree species on less fertile soils, and it is now one
of the commonest pioneer tree species in disturbed areas.

Also Acer negundo is naturalized locally.

Few days ago there was writings about Ailanthus in the ENTS forum.
Ailanthus spreads in Central Europe as well, but is not yet so bad
problem as in southern Europe. For example, in Italy it is present
everywhere. Really everywhere!

Gary and Will B.

After checking out the floridata website on the east coast and gulf
coast varieties, I made a trip out to a stand of Yellow Poplar to see
what ours in SE GA looked like. I feel like ours are more closely
alligned with the Florida East Coast variety. The photo of the Gulf
Coast variety favored what I see up in the N. GA mountains and
piedmont. I have uploaded a photo to the files section. I also
uploaded two Red Maple photos taken in the same springhead, one
showing a bright red petioles and a strongly glaucous backside to the
leaf and another tree right next to it with a more reddish green
petiole and a non glaucous greenish backside to the leaf. Both
variations are quite common in the area, with the glaucous variety
probably more common. Even in Jan and Feb when they flower, the
glaucous ones will have bright red flowers and seeds while the non
glaucous will bloom a brownish yellow color.

And also if you are keeping record, the Yellow Poplar are now in
flower here. I haven't been there in several weeks, but I would guess
they have been in flower at least a week. They leaved out in late Feb
so that would put flowering about 4-5 weeks after leaf out.

ENTS:

Yesterday we had the first day of the year in central WV where the
temperatures got solidly above 70 and the first signs of green started to appear on
the yellow poplar trees as the buds broke open. I have been in the woods every
day of the past three weeks and yesterday was the first poplar leaves to
show green and nothing was showing less than 24 hours before. The first trees
to open are on upper slopes of coves that have northwesterly exposures.

The spice bush started flowering in earnest last week and any place with
spice bush is so thick with pollen that it can be hard to breathe.

On Sunday, April 6 the first of the understory buckeye trees sprouted their
leaves and multifloral rose leaves reached 1/4 inch in length. Also on
Sunday pear trees started to flower and bats started to hit the skies.

On Wednesday, April 2 Microstegium vimineum (Japanese stiltgrass) a lethal
invasive grass started to germinate on warmer forested sites with eastern
exposures.

I have not seen any snakes yet but my wildlife encounters for the past week
include almost stepping on a woodcock yesterday...I came within a foot of it
and it took off just before I placed my foot where it had been sitting. It
was a little more surprising that a ruffed grouse because it matched the leaves
on the forest floor so closely that the bird was nearly invisible prior to
exploding in flight.

Ruffed grouse are drumming everywhere they have habitat and tadpoles are
starting to show up in any body of water with no fish.

Last Wednesday was a cool day but it was warm enough to bring out the box
turtles and I came across one in the woods that was all covered with mud and
dirt as it was emerging from the hole on a steeply sloping hillside where it had
taken up winter residence.

The ramps are now about 6" tall and ready for eating.

Russ,

Great report on the first signs of Liriodendron budburst and other
plants. Thank you.
I have a backyard Liriodendron (12') that is just starting to open its
buds (I suspect it is a cultivar from further south because the native
trees won't start for another 3 weeks or so).

Now if we can get a report from Ohio and other states to the west that
would be super! ENTS?

Hi All,

One of the two Liriodendron I'm observing made leaf burst on Friday, April
4th. Interestingly, the one next to it is a few days behind.

These trees are on the NW edge of the Richmond's Dollar Parking Lot next to
Eastern Kentucky University - *http://tinyurl.com/57cdn4 *[you can see the
shadow of these two trees just N of the green arrow on the map]. During last
yr's early warm up and severe, 5-day April frost, the tree that has opened
the most this yr was completely devastated and took longer to recover than
the tree still somewhat in bud; makes for a great plant phys lecture 'A yr
in the life of a tulip-poplar'.

Even though Richmond is relatively small, it has a significant urban heat
island effect. Don Yow has found some surprising difference between downtown
and city-edge temperatures in our small town of 30,000:
http://people.eku.edu/yowd//uhisite/index.htm - it is warmed than expected
in Richmond vs its outskirts.

For example, I took my Ecology For Teachers class to Maywoods, 23 miles
southwest of Richmond last Saturday. The sugar maple next to my office is in
full bloom. The maples at Maywoods were still in winter slumber.

Related - in Maywoods, serviceberry was in full bloom, too. At Pioneer
Mothers Memorial Forest in southern Indiana, bloodroot was blooming this
past Sunday. [I'll be happy to send pix of this forest if ya'd like, Ed -

I hope to make it up to MA some time later this year and I will definitely
give a heads up on my travel to the North country.

I have to drive so much for work that I have almost no money left for any
pleasure travel so I don't see myself coming to the meeting you mentioned next
week. Sometimes it is a little hard living and working in a place where
travel distance in measured in hours instead of miles. I work on property close
to home that is only ten miles away but well over an hour in travel time and
I also work on property that is over 160 miles away and less than a 2 1/2
hours drive from home. I get 20 miles per gallon on the 160 drive but I sure
don't get it on the 10 mile drive!

Yesterday I had to drive about 60 miles from home and can report that
opening of the yellow poplar buds has become widespread in WV. Also, yesterday,
April 7 beech buds started to open. Just a couple of days ago the swelling of
the beech buds was barely noticeable but the high temperature yesterday
(approaching 80 degrees) forced some major changes in the beech. Morel mushrooms
have started to show up but I have yet to pick my first ones of the year.

Carolina wrens are checking out every small opening they can find to locate
nesting sites and squirrels are actively digging up the last remaining walnuts
still on our lawn from last year. It drives the cats crazy but it has been
a couple of years since they have caught one. From my computer I look out
across the yard and have noticed that the harder it rains the more active the
squirrels get....in a raging downpour there might be as many as 4 of the bushy
tailed rodents digging up walnuts on the lawn while the cats are sitting on
the porch ledge and window sills wag their tails and utter feline obscenities
at the brash interlopers.

Yesterday the white ash trees also started to flower.

Now I gotta get to the woods for the day.

The two Liriodendron are planted. As they are in a park, it is hard to
say if they are cultivars. A larger and certainly older Lirio in the
campus Ravine [amphitheater & park] leafed out on Monday, the 7th. If
the two I was watching are not local, this one is more likely to be of
more native stock. Lirio in the forest outside of town were not moving
too much.

Notwithstanding the winter storm watch we have for Thursday and Friday,
silver maple is in full bloom (its always the first tree species to show
any sign of spring) in southern Minnesota (45 degrees latitude). It looks
like the main part of the approaching storm will go north of Minneapolis;
10-20 inches of snow, sustained winds of 40-50 mph, and 20 foot waves on
Lake Superior are predicted for Duluth.

The boreal forest of northeastern MN (48 degrees latitude) currently has a
snow pack of 40-50 inches, which was greatly enlarged by the historic storm
April 5-7, where as much as 32 inches of snow fell near Virginia, MN, and
it will get at least a foot deeper with the coming storm. We need not be in
any hurry to get field work on tree regeneration in the areas burned by the
big fires of 2006 and 2007 in the Boundary Waters underway--the snow on our
study areas probably won't melt until the semester is over in mid may. Its
going to be quite the flood when that snowpack is liquidated and comes
rushing down the Mississippi through Minneapolis in a few weeks.

Typical La Nina winter--we won't see any leaves on the trees until mid May
in Minneapolis and early June in the north.

I have been in the woods so much marveling at our spring that I forgot the
actual date of the poplar leaf out. General leaf out in central WV for the YP
was between April 9 and 11.

The peak flowering of sugar maple was on April 20 and chestnut oak started
to flower on April 24 and white oak started to flower like crazy on April 26.

Goldenseal emerged and started to flower on Sunday, April 27 and American
ginseng emerged on April 27, the same day as Virginia snakeroot came out. Red
elm seed has now matured and it is raining down every time a breeze hits.
There are no flowers yet on the yellow poplar and the leaves are now about 70%
out.

Red oak and scarlet oak started to flower on April 27.

April 27 was a big day because on the night of April 26 we had our first
decent rain in a week and the foliage and understory exploded.

We are in the midst of the mother of all morel seasons in WV. They are
growing in profusion every place you can find yellow poplar and have been so
plentiful that I have been frying up a large skillet full every night for over a
week to have with our supper. My neighbors have been selling them for
$100/gallon but we are keeping and cooking all we can. I was amazed to find out
that there are almost 200 listings of fresh morels on Ebay.

Gary,

my mom checked leafout and flowering of three tuliptrees that I planted on their property. All three had not leafed out on the 23rd of April, but on the 26th all three of them had open leaves at all four cardinal directions. It seems likely that all three had open leaves a day earlier than the 26th. Two of the three tuliptrees were flowering on the 2nd of June. They were not checked the day before, but only about 6 or 7 flowers were open on each tree near the top. These were the two larger trees and both were transplanted from Hillsdale County, Michigan. This location is about halfway between North Adams and Pittsford and 15 miles north of the Ohio border. My parents home is located in Milford and it is about 57 miles north of the Ohio border and about 90 miles or so northeast of the origin of the tuliptrees. The other tuliptree was not flowering on the 2nd of June and it was purchased from the state of Michigan. I have no idea of the origin of
this plant, but I always thought it might be from south of Michigan since it always holds its leaves significantly longer in the fall. This tuliptree was flowering on the 9th of June, but not on the 6th. My mom seems to think it might have been flowering a day or even two days before the 9th, but she did not check it on these days.

Last year I missed leafout of the tuliptrees, but I tried to determine first flowering. I was there in late May for my dad's 70th birthday party, but the trees were not flowering at that time. My parents were on vacation during the first week of June and when they came back (I think it was around the 10th) all of the trees were flowering. So it seems that they also began flowering during the first week of June last year as well.

Thanks very much Doug, very helpful.

Is there anyone on the ENTS list from Ontario?
