Likes Your Post

I added a nee MOD and gave everyone permission to use it. It is much like the "Like" button on Facebook, for those of you familiar with Facebook. There is a button on the upper right corner of the message that vaguely looks like a "Thumbs Up" icon. Just click on it. The "Likes your message" count appearing below the posters name and icon will go up by one, and your name will be added to a list of people who liked the post at the bottom of the message. The button doesn't really do anything more than that. It is just an acknowledgment that the post was read and found interesting. The button doesn't appear on announcements, but should be there for everyone in every post. After you click the thumbs up the icon changes to a thumbs down icon. Clicking again will take away your likes. This in effects allows you to acknowledge you read the post and like it even if you do not have any specific comment to add.


Links to Between the ENTS website and the ENTS BBS

I have been doing some other upgrades to the BBS over the past couple of days. First you may have noticed I placed links on every forum on the BBS to the equivalent index page on the ENTS and WNTS website, and I also placed links on every index page on the websites to the corresponding forum on the BBS so that navigation between the two will be as seamless as possible.


Daily Digest

I also want to encourage people to subscribe to the "Daily Digest" which sends a summary of all of the posts made each day out as a single email to subscribers. In this way you can be sure that you will not miss a post and have an opportunity to see what everyone is talking about even if you do not browse all of the forums. It is a great asset and I want people to use it. The options for the Digest are under the User Control Panel page that can be accessed by clicking on the User Control Panel link at the upper left side of the BBS . Then click on the Digest tab to set your options.

MTSF - Four Graces

ENTS,

On Friday DCR District Manager and friend Tim Zelazo visited the north section of MTSF and named a cluster of 4 trees for members of DCR who stand tall in the protection of our precious natural, historical, and cultural heritages located on public lands. After I named the new 150 for Robert Campanile, the naming event for the remaining 3 trees went to Tim. Tim photographed two of the 4 trees. Light conditions did not allow for all 4 to be captured on film at the time we were there. Although we did not discuss the overall potential significance of the naming of the Four Graces, I think we both sensed that it was an important step. We didn't know how those being honored would react. For example, would they feel self-conscious or awkward? Finding out was Tim's assignment. I was most thankful for that.

Friday's dedication has since given me pause to reflect on the meaning of the event. I am only now coming to realize its potential significance. It takes dedicated people inside and outside government to value and protect our heritage. Often there are selfless warriors for the environment inside government who work everyday for the protection of the resource entrusted to them, yet receive no public recognition or appreciation. They sometimes are forced to make compromises to keeping the wheels turning, but they never lose sight of the resource or its value. I am thinking of writing an essay about the Four Graces and making it the basis for a submission to a future edition of the Bulletin of the Eastern Native Tree Society. I also want to undertake this assignment out of appreciation to my friends who enjoy my articles and descriptions. At this moment, I am thinking of Larry, James, Ed, and Marc who regularly comment on the articles I write. Dis Bud's for you guys!

Early Spring, Western PA

ENTS,

I went out for a short drive yesterday to catch a few images of the early spring colors. We often think of the fal foliae in terms of color, but there is color in the spring as well. Beyond the pale green of youg leaves are the bright white bursts of cherry flowers, red maple flowers, and even the red leaves of the maples as the first burst out of their buds. We still have the grays of the winter bark. The brown beech leaves still cloth the tree. The bright green of hemlock and white pine stand in contrast to the bare branches and teh first hnts of spring color. I wanted to try and capture some of these things before this passing momment of the spring season passed.

Aldo Leopold

Aldo Leopold

Aldoleopold.jpg

The following text is from http://en.wikipedia.org/wiki/Aldo_Leopold
Aldo Leopold (January 11, 1887 – April 21, 1948) was an American ecologist, forester, and environmentalist. He was a professor at the University of Wisconsin and is best known for his book A Sand County Almanac (1949), which sold over a million copies. Influential in the development of modern environmental ethics and in the movement for wilderness conservation, his ethics of nature and wildlife preservation had a profound impact on the radical wing of the environmental movement, with his biocentric or holistic ethics regarding land. He emphasized biodiversity and ecology and was a founder of the science of wildlife management.

His nature writing is notable for its simple directness. His portrayals of various natural environments through which he had moved, or had known for many years, displayed impressive intimacy with what exists and happens in nature. Leopold offered frank criticism of the harm he believed was frequently done to natural systems (such as land) out of a sense of a culture or society's sovereign ownership over the land base – eclipsing any sense of a community of life to which humans belong. A Sand County Almanac
The book was published in 1949, shortly after Leopold's death. One of the well-known quotes from the book which clarifies his land ethic is
A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise. (p.240)

Back to Mohawk

ENTS,

Earlier today I led a group from the Springfield Naturalist Club on a guided tour of the more accessible big tree sections of MTSF. We reached our destinations mostly by trail, a not typical course for me, but trails do serve useful purposes. A big one is to minimize damage to fragile vegetation. Another is to get people to scenic areas without fear of accident. Since the age of the majority of participants equaled my own, today was no time for off trail excursions through boulder fields with tricky footing.

Today's program allowed me to reconnect with old friends - one from over 30 years ago. We stared at each other's thinning gray hair and accumulation of wrinkles. Could we be the same people? After sharing memories, we concluded that we were. Others I hadn't seen for over a decade. It was quite a reunion.

I'd done programs for the Springfield Naturalist Club in the past and I like those folks very much. On my last program, I had taken them to Monroe State Forest. It had made an impact. However, I had never done a program for the Club in Mohawk. Naturally, I wanted the members to take to my forest Mecca, and they did. Mohawk's wealth of beautiful trees began working their magic. They always do. I see people leave in what I've come to call the woodland trance. As evidence of the forest elixir, at the end of the walk, every single member shook my hand - the first time that has happened for so large a group. Were I in the mood to indulge my modest ego, I might think in a self-congratulatory way, but on deeper reflection, I would have to acknowledge that it wasn't me they were thanking - other than to lead them to spots. They certainly weren't applauding my endless spewing out of numbers: tree measurements, the altitudes of surrounding peaks, acreages, dates, climate statistics - you name it. No, it was the trees that wowed them - and in particular, the great whites. The charismatic pines of Mohawk always impress visitors, at least those who are tree savvy and appreciative. Never fails.

At our parting, the members of the club pledged to come to the aid of Mohawk should anything ever threaten that irreplaceable forest icon. In hearing their words, I felt a deep sense of relief, knowing that Mohawk has powerful allies. I hadn't forgotten that the Springfield Naturalist Club came to the aid of Mount Tom State Reservation in the mid-1980s and halted a foolish timber sale then planned by the Department of Environmental Management. Mass Audubon and other mainstream environmental organizations had thrown in the towel, but the Naturalist Club persevered and won.

Back to the present, it was especially good to see Mohawk today after Monica's and my return from Virginia. I needed a reaffirmation. On the Madison Estate, I was constantly cognizant that I was in the domain of the lordly tuliptree--tallest of all native eastern hardwoods and the tree of my youth. In MTSF, I had returned to the kingdom of the great whites, tallest of all native eastern species, including the tulips. That said, in fairness, I should point out that the white pine eclipses the tulip by only a few feet in today's growing environment and there are far more towering tulips than pines. Additionally, in the southern Appalachians, the tulips and white pines often go head to head. However, the battles don't end that way elsewhere. In northern climes, the great whites win hands down. But in the mid-west, the tulips win just as handily. It is nip and tuck - a worthy contest. So is measuring both species. Each has its special challenges that can leave the measurer mumbling in single syllable words of four letters each.

For comparison of the species, today, my memories of Virginia were still fresh. At Montpelier, I struggled to find the tops of towering tulips with the three lasers I used. I was in their world and they were not going to reveal their dimensions without a battle, or at least a test of my will power--I like to think the latter. It was as if Montpelier's tulips were silently whispering, "measure me, Bob Leverett, if you can, but beware, I will not divulge my stature to you readily. I will never allow you to take me for granted. You must work and work hard, for I am lord of my domain. You must be humble in my presence."

In Mohawk, I don't get a similar feeling of resistance when measuring the white pines, although I often must take a lot of time to measure individual trees. I attribute measuring difficulties to the crowded configuration of many pine groves, as opposed to a resistance to being measured. I account for the difference in my perception this way - another flight of imagination, I suppose.

It is no secret that I like to compare and contrast the tulips and great whites. But it isn't a simple comparison of statures, as readers might expect from my frequent postings on tree measuring. Comparisons form along many lines of perception, straightforward and subtle. For instance, in Montpelier, I found the light green foliage of the tulips uplifting to my spirit. The almost iridescent green of tulip leaves imparts a spring-like feeling long after spring has bowed to summer. When the tulips bloom, it is easy to imagine oneself in a tropical setting. But there is more to the effect than leaves and flowers. The light-colored bark of the tulips seems to air out the forest. The tulips lift do our spirits, whether the trees are young or old and whether we are junior or senior. How about the pines?

In Mohawk, the dark green foliage of the lofty pines imparts a slight somber or stern sense to the woodlands, though not always. One does feel oneself in a more northerly clime, though, and that connotes rugged character. In mixed stands of conifers and deciduous trees, the white pines often thrust their crowns through the shorter canopy of hardwoods. In doing that they communicate their great heights and give meaning to the ecological concept of super canopy. In the regions where these two charismatic species dominate, they create energy gestalts that leave their imprints on the surrounding countryside. I am loathe to place one imprint, tulip or white pine, on a higher pedestal than the other. I am thankful for both, but alas, I cannot help perpetually contrasting and comparing, searching for the right words to convey what will always remain elusive. For me, comparison is in the genes, but so is my undying admiration for these two noble species. They are so different and that has made me think about what makes each so powerful. When I am among the tall tulips of my native South, I acknowledge that their energy signature is distinctly their own. No other species leaves the same imprint on its surroundings and the sheer dominance of the tuliptree's size insures that the energy imprint is intense. But, the same can be said of the great whites of the northeastern states. They dominate their surroundings as thoroughly as the tulips. Maybe it is partly my fixation on stature.

Both species tower to dizzying heights. They leave their competitors to gaze longingly upward. In direct dimensional comparisons, the tulips are more massive, but the whites have an oddly reassuring presence that seems to counterbalance what they give up in girth. I think it has to do with their darker, deeply furrowed bark. An then there is the unconscious awareness of the immensely historical role of the great whites in New England. But no sooner have I called the white pine's cards to the table than tulip awareness surges in my frontal lobes. Remember me, I am the tree of your youth. I am the true giant of the forest. In the end, I pronounce the contest a draw. No losers. Only winners.

Thinking in a different direction, I think of the white pines of the north and the tulips of the south as somehow being aware of the other. This probably sounds foolish, a product of a bizarre, overworked imagination, but in a distant, multi-dimensional way, maybe the two species are connected as mutually respectful arboreal relatives, each content to rule in its distinctive domain - one to the north and the other to the south. But, if the climate continues to warm, will the tulips establish a stronger presence in the north? What will happen to the great whites. That's a worry I will gladly put off for another day.

If this contorted comparing and contrasting seems excessive to any of you reading this essay, others would agree. I recall a young woman on a walk who had absorbed all the comparing and contrasting she could handle and timidly explained that she liked all trees, large and small, old and young. I sheepishly acknowledged her point and agreed with her. It was my way of making her feel that she hadn't crossed any boundaries. However, on subsequently thinking more deeply on the subject, I realized that I didn't like all trees the same. To do so would be to deny their individuality. It would be as though I liked all people the same, which I don't. Trees are individuals. Were I to feel compelled to like them all, then I'd have to like those little ornamental pear trees that people plant in their yards after removing perfectly fine native species. It is as though people must leave their territorial marks and force conformity. I have a hard time accepting those little human engineered forms as true trees. So, my acknowledgment to myself is that some trees inspire me. Some don't. I feel no need to apologize for that. All trees are not created equal.

Well, I've rambled enough. Back to Mohawk. I took only one photo today. It was a shot of three of the Council Pines, some of Monica's favorites trees. She has a spot among them where she sits quietly and meditates while I scurry around measuring. It is a special spot for both of us and one today that I felt like sharing with the group. It also afforded me the opportunity to continue my efforts at capturing the different looks of important places and trees. As the seasons change, as the light increases or decreases, as the amount of green waxes or wanes, and forest moods become strikingly different. I want to capture those differences. Today, the pines were seen through brighter light. As a consequence, they looked appreciably different from the last time I saw them. So, I tried to capture today's look. To mercifully end my rambling, I present the single image of the Council Pines in the Pocumtuck Grove.

FFVP Report

ENTS,

Today I went to a briefing on the end of the Forest Futures Visioning Process held by Commissioner Rick Sullivan of DCR and EOEEA Secretary Ian Bowles. It looks like we will get 60% of the 308,000 acres under DCR's control set aside for reserves and parklands. Some of the DFW and Reservoir lands totaling an additional 250,000 acres will also be set aside in reserves. I believe the final reserves and parklands acreages will exceed 200,000 acres. That amounts to at least 80,000 more than we thought we were getting on the initial establishment of the reserves. We currently are at just under 50,000 acres. Give the amount of opposition to parklands and reserves, I consider this a major victory.

I also had a discussion with the Secretary and he wants me to contact him for possible tours of the special forests sites. That is a big leap forward. I also had a good talk with Commissioner Sullivan and gave him a copy of the ENTS Bulletin. I think he may just read it. I have infrequent communications with Sullivan and they've all been satisfactory.

Toward the end of the gathering I spent time shmoozing with DCR's recreational arm. That went very well. They like ENTS and support us. So, the good news is that our (ENTS) stock is definitely on the rise. I do believe we will be called upon to help identify more forest reserves. Wicked cool! If I were a drinking man, I'd be gulping old fashions, martinis, or Jack Daniels on the rocks. But I'm not, so this Kool Aid will have to do. Maybe the rest of you can guzzle a brew or two in celebration of ENTS accomplishments in protecting great forest sites like Mohawk and Monroe. Life is good. Life is good.

Re: Claremont NH

ENTS

Monica and I got a very late start for Claremont, but we did go. As a mix of snow and rain pelted us, Monica and I trekked through the private site. Our time was very limited, so we went straight to the area where the tallest trees grow. I spent my time measuring trees in two ravines. Here are the 9 pines I measured:

Pine# Height Girth

1 147.5 ft
2 150.1 ft
3 155.3 ft
4 157.5 ft
5 159.8 ft
6 162.3 ft
7 162.9 ft
8 164.1 ft 9.4 ft
9 166.2 ft 8.2 ft (tallest known tree in New Hampshire)

There are many 150s on the site, perhaps as many as 70 and I think there are between 8 and 10 160s. I will return in late October to intensively measure the stand. Great site. Tree #8 was climbed by will Blozan back in 2003, I think.

Monica was operating the camera, but something went amiss, so we don't have any images of the tall trees. We'll make up for it in October. The two images I do have show a huge pine near our friend's house. It measures 12.7 feet in girth and is 116.0 feet tall.

Buckland SF

ENTS:

Last winter I visited a small state forest holding in Buckland , which has a small but impressive softwood plantation consisting mostly of Norway Spruce and Eastern Mountain Larch. (Thanks to Tim Zelazo for identifying this tree, which I for some reason thought was dead red spruce! I assume it is larix decidua: http://www.conifers.org/pi/la/decidua.htm) I revisited the site today to confirm the two tallest trees, and connect with the site in its springtime state.

The larches are leafing out nicely. I was able to find the tallest one and remeasured it carefully, getting 147.2'h x 7.05'c (at 4.5'). Another example nearby measured 140.8' h x 5.8'c. I haven't seen any other reports on this species. For Massachusetts I believe it is the third tallest species of tree.

And, the fourth tallest species would be Norway spruce. In the same grove are two of them that reach 145'. I relocated one of them today, and remeasured it to 145.0'h x 7.35'c. I have found quite a few in this stand that exceed 130'.

I remeasured the tall white ash, getting 129.5'h x 7.3'c, and nearby found the surprise of the day, a black cherry that measured 124.5'h x 5.2'c. It is possible that this is the tallest cherry in Massachusetts, since neither of the 125'ers from MTSF have been relocated recently.

This is quite a site. I hope to return soon to take photos and fill out a Rucker index.

John

p.s. I have attached a chart of data from this site, and a draft of a historical all-species Rucker index for Massachusetts. Two trees from this site are on that list.

Bryant Homstead Visit

ENTS,

Earlier today, I met my buddy Gary Beluzo at the William Cullen Bryant Homestead in Cummington, MA. Gary wanted to test mehtods for photographic stitching of images in horizontal layout format and I wanted to build a better library of simple images for the Bryant forest, and measure a few trees. I suppose the latter goes without saying.

The Bryant Homestead was constructed in 1785 and is the boyhood home of William Cullen Bryant (1794-1878). The homestead is managed by the Trustees of Reservations, a very worthy conservation organization that I fully support. TTOR manages nearly 25,000 acres spread over more than 100 properties and is generally considered to be one of the oldest conservation organizations in the nation. TTOR has some real jewels and the Bryant Homestead is one of the jewels. The property contains a small area of old growth and one of the truly great white pines stands in New England. As was introduced to the pines around 1990 by my friend Jack Sobon. We've since monitored the growth of the pines. We have records extending overly nearly 20 years. Unfortunately, the pines were hit pretty hard by last winter's ice storm, but though many limbs were lost, the big trees survived. It will take a few years to heal the wounds, but I have faith. The Bryant pines get pummeled every few years, but continue to grow.

As we started down the Rivulet Trail, a hobble bush caught my eye. The image below shows the bright green leaves and snowy white flowers - a sure sight of the progression of spring. Soon the hobble bush and other shrubs and deciduous trees will complete leaf out and the canopy will close and tree measuring season will end. Realizing that, I needed to take full advantage of the opportunity to take some last measurements of the tall pines while I could still see their tops. But first, the flowers were demanding my attention.

HobbeleBush.jpg

A treat for any visit to the Bryant woods is a chance to commune with the old hemlocks. They, more than any other species carry the theme of old growth and heritage trees for the Homestead. There is presently no adelgid in Bryant so the hemlocks look splendid. The image below shows a group of hemlocks that we've dated to between 230 and 270 years of age. There are many hemlocks over 175 years and I expect a few over 300, but most of the old ones appear to be in the age interval cited above.

Hemlocks.jpg

The main walking trail on the Bryant property is the Rivulet Trail. For years that was the primary nature trail. However there is now a loop trail off the Rivulet Trail called the Pine Loop Trail. I had the honor of laying it out a number of years ago. I will always be beholding to the Trustrees in following through in acknowledging the value of a pine stand adjacent to the area with the Rivulet Trail and accepting my recommendations. The treasure of the trail is the stand of gargantuan white pines that the trail passes through. There are a number of pines over 11 feet in girth and 3 or 4 over 150 feet in height. At one time, there were 6 over 150, but the winters pare back their crowns. There are many over 10 feet in girth and 140 feet in height. The following image is of a big pine measuring 11.7 feet in girth, but only 120 feet in height, thanks to that miserable ice storm.

Giant1.jpg

A short distance farther, I reached the second of the huge pines at the west end of the property. It measures 13.1 feet in girth and 142.4 feet in girth. I have its trunk volume calculated to be 739 cubic feet. I originally had its girth even more, but using the Will Blozan method for determining girth, I have settled on 13.1 feet. The first of the following two images shows the Patriarch Pine - its new name. The second image shows Gary Beluzo among other big bruisers in the process of photographing the Patriarch.

BigBoy.jpg

GaryPhotographingtheBigBoy.jpg

A short distance from Gary in the preceding image stands a magnificent pine that we both photographed. I think the name Centurion fits that pine. So the Centurion it is. The next two images show Centurion.

MajesticPine.jpg

MajesticPine2.jpg

Oh yes, Centurion's dimensions. Hmm, now what were they? Oh yes, Girth = 12.0 feet and height = 149.3 feet. That is a higher number than I previously got. The answer apparently lies in last winter's ice storm. It thinned the crown enough for me to hit spots in the crown's interior that I could not previously measure with the laser. Finding the absolute top of tall white pines is a task not for the feint of heart. You often have to climb them. Otherwise you get lucky if measuring from the ground.

I once confirmed 6 white pines in Bryant to over 150. However, the winters do damage. They pare back the crowns of many. What about Bryant's flagship tree? No problem. It came through the ice storm with crown entirely intact. Bryant's tallest pines is appropriately enough, the Bryant Pine. It is shown in the following two images.

BryantPine1.jpg

BryantPine2.jpg

Today, I remeasured the Bryant Pine at 156.7 feet in height and 10.3 feet in girth. My last measurement was 156.6, so I'm within the range. It is unquestionablly the tallest tree on the Bryant property and I'm confident on all TTOR properties. Jack Sobon measured it in 1991 with a transit to 149 feet and a few inches.

The big Bryant Pines should not be an exclusive old boy's club. The next image shows the Emily Dickinson Pine (far right) and other trees in the vicinity. It's Emily's family. The Emily Dickinson Pine is one of those that has lost crown due to teh ravages of winter. At one time Will Blozan gt 154 feet for Emily. Now the big tree just exceeds 148 feet. Its girth is 10.8 feet.

EmilyAndFamily.jpg

Gary and I also measured an impressive pine on the opposite side and down trail from Emily's pine, which we decided to name the Lynn Margulis Pine, in honor of that great scientist who lives on part of the Emily Dickinson property. Lynn was Gary's mentor. Dr. Margulis is one of the truly great scientific thinkers of our time. She was once married to astronomer Carl Sagan. The dimension of Lynn's tree are Girth = 10.6 feet and height = 143.7 feet. Gary took the images.

As a last image, I present a lovely unnamed old yellow birch. There are many old birches on the Bryant property and I expect they are around the same age as the oldest hemlocks. None are exceptionally large or tall, but they have a commanding presence.

Re: Tall European trees

Kouta,

To evaluate the accuracy of the measurements of the Slovakian reserve Hrončokovský grúň whe should have to visit it with laser equipment. To measure hardwood / broadleaf trees in a forest its much easier to measure without leafs.
Personally I think some of these heights will be a bit exaggerated.

I've bought a Nikon Forestry 550 laser ranger last September, its working fine. Before that I did height measurement with a Suunto clinometer and a tape. Because I had contact for several years with ENTS I knew the problems with tangential measuring. So most of my Suunto measurements were rather good, but took a lot of time. The laser is much easier and more accurate. A friend of mine, Leo Goudzwaard, is working for the Forestry research group of Wageningen University (Netherlands). Till recently, he did height measuring with the Suunto clinometer as well as with a Digital Hypsometer Forestor Vertex, I think it is the same type as the Haglöf Vertex III Ultrasonic Hypsometer used by Holeksa et al.
When testing all methodes together it was easily seen that great mismeasurements could be made with the Hypsometer when one did not recognise the real horizontal distance to the measured top. Before Leo realised this, he made mismeasurements up to 12 %. This has been said many, many times by Robert Leverett, Will Blozan and others.
So, I think the measurements of Holeksa easily can be wrong for over 10 %.

Leo Goudzwaard now has bought also a Nikon Forestry laser ranger.

The measurements of Fraxinus excelsior reported by Waldherr probably have been done with a clinometer and also could be wrong for over 10%.

A Polish measurer, Thomasz Niechoda, has measured recently with Suunto clinometer Fraxinus excelsior of 45 - 46 m in Bialowieza, Poland. I have warned him for the risks of this kind of measurement. Till now he has measured maxima in Bialowieza of 48 to 50 m for Picea abies, 41 m for Quercus robur and 36 m for Tilia cordata. This seems to be trusted, so I think he measures as good as possible with this method.

About Fagus sylvatica: with the Nikon Forestry 550 I have measured hundreds of them in the Netherlands at many locations. Only at three places near Arnhem I found beeches of 42 to 43 m (138 - 141 ft). At the Middachten Estate there are still 2 beeches of 43 m (141 ft). In a lane cut in nov. 2005 I measured a fallen beech with a lenght of 44,25 m (145,18 ft). Next to it had stood a taller one, probably 2 m taller, what could be seen from outside the lane. It had been measured by Leo Goudzwaard with the Digital Hypsometer Forestor Vertex as 48,5 m (159,12 ft), but by the forestor of the estate with a clinometer as 46 m (150,9 ft). This seemed to be right. Another beech of 47,3 m (155,18 ft) has been measured a few years ago when blown over in the estate of Amelisweerd near Utrecht. I have doubts about this, the tallest beech I have measured in that forest with the Nikon is 40,5 m (132,87 ft).
A acquaintance of mine has climbed and tape-dropped a beech in eastern Germany (former GDR) of 49 m. This seems accurate, but it was done several years ago in a climbing competition and perhaps not with the greatest possible accuracy.

I updated the list for the Netherlands in April 2013. There are few substantial changes found in the three years since I posted this list. For the whole of Europe there have been found many more new record heights.

My own list of tallest trees in the Netherlands measured by Nikon Forestry 550 laser:
Scientific name - English name - records 2010 - Update 12-04-2013
Pseudotsuga menziesii - Douglas fir - 50,3 m (laser) - 49,75 m (climbing + tapedrop; lasermeasurement in 2010 was
without direct view of the base)
Fagus sylvatica - European beech - 43,0 m - 43,2 m
Picea abies - Norway spruce - 42,1 m - 42,1 m
Abies grandis - Grand fir - 42,0 m - 42,0 m
Populus x canadensis - Hybrid poplar - 41,2 m - 41,7 m
Quercus robur - English oak - 41,2 m - 41,8 m
Sequoiadendron gig. - Giant sequoia - 41,0 m - 41,5 m
Quercus rubra - N. red oak - 39,6 m - 39,6 m
Thuja plicata - Western red cedar - 39,4 m - 39,8 m
Populus x canescens - Grey poplar - 39,1 m - 39,1 m
Larix decidua - European Larch - 39,0 m - 40,0 m
Platanus x hispanica - London plane - 39,0 m - 39,0 m
Fraxinus excelsior - European white ash - 38,6 m - 39,5 m
Liriodendron tulipifera - Tulip tree - 38,0 m - 37,6 m
Acer pseudoplatanus - Sycamore maple - 37,0 m - 37,0 m
Aesculus hippocastanum - Horse chestnut - 36,0 m - 36,8 m
Tilia platyphyllos - Broadleafed lime - 35,2 m - 35,2 m
Ulmus glabra - Wych elm - 35,0 m - 35,0 m
Salix alba - white willow - 34,6 m - 34,6 m
Tilia x europea - common lime - 34,6 m - 36,8 m
Tilia tomentosa - silver lime - 34,4 m - 34,4 m
Taxodium distichum - swamp cypress - 34,0 m - 34,6 m
Tsuga heterophylla - western hemlock - 34,0 m - 34,5 m
Quercus cerris - Turkey oak - 34,0 m - 34,2 m
Juglans nigra - black walnut - 33,8 m - 35,2 m
Pinus sylvestris - Scots pine - 33,6 m - 33,6 m
Quercus petraea - Sessile oak - 33,5 m - 33,5 m
Quercus palustris - Pin oak - 33,0 m - 33,8 m
Platanus orientalis - oriental plane - 33,0 m - 33,0 m
Alnus glutinosa - common alder - 33,0 m - 33,0 m
Castanea sativa - European sweet chestnut - 33,0 m - 34,6 m
Quercus frainetto - Hungarian oak - 32,6 m - 32,6 m
Metasequoia glyptostr. - dawn redwood - 32,0 m - 32,8 m
Pinus nigra - black pine - 32,0 m - 34,8 m
Prunus avium - wild cherry - 31,6 m - 31,6 m
Acer platanoides - Norway maple - 30,2 m - 32,0 m
Betula pendula - silver birch - 30,0 m - 32,4 m
Cryptomeria japonica - Japanese red cedar - 30,0 m - 30,8 m
Carpinus betulus - common hornbeam - 29,0 m - 32,2 m

For some species these records will be very near the real maximum for Holland, for others not yet.

In the UK there are now done very accururate height measurements by the British Tree Register with laser and climbing with tape drop. In Germany some of these accurate measuring has also been done recently. Still I did not see accurate listings of Germany of the whole country for many species. Its sure in Germany many species will have taller individuals compared to Holland.

It should be nice if you could persuade Holeksa et al. to use laser equipment to meassure this forest.

Re: Why do we find trees so rapturous?

I suggest that Huxley's concept of a "reducing valve" is more than that- it's an "interpretation valve"- if all it did was reduce input, that might not do much for us, but as we live, we keep building and modifying an interpretation valve- so that all the input is not just filtered but transformed into meaning, which is just as often wrong as right- so that it adds confusion and misunderstanding- so by reducing that valve, we can clear some of the fog out of our brains- the fog of religion, racism, nationalism, and propaganda of all sorts- along with our own false theories of reality. Of course some people can't bear facing "the ground of their being" as some philosophers say.

Regarding trees, seeing them for what they are, living creatures, can be an epiphany, or so those who've experimented often say.

White Pine Crowns, Cook Forest SP, PA

Yesterday, March 17, 2013 I led a group on a hike through the Forest Cathedral Area of Cook Forest State Park. I paused before the hike to take a few shots of the old growth white pine crowns on the hillside above the Clarion River and above the Seneca Trail. The broken and gnarled nature of the crowns of these trees sticking up in the weather for hundreds of years is very impressive.

A final shot along the Ancient Forest Trail.

The park was beautiful with fresh snow hanging on the hemlock branches. It is sad to think how the park will change with the coming of the hemlock wooly adelgid over the next few years. I was leading a good sized group on a hike, and afterward was pressed for time afterward, so I did not get a chance to do the photography I would have liked. These really are color photos.
