Tallest Tree South Of SF Bay Confirmed

I finally measured the tall redwoods Zane Moore reported from Big Basin State Park a few months ago.

With the help of Zane, his father Steve and Big Basin park ranger Susan Blake, I came up with 327.39 (99.7m) feet for the tallest and 323.8 feet for the nearby 2nd tallest redwood which grows in the same grove. I measured to under the duff layer at the tree's base. Zane went to above the duff layer. The prism/pole with Impulse200LR "leap-frog" survey was used. The numbers were not added up until the very end. The window to the top was from way up on a nearby hill. Judging by the attached picture I hit the true top of the trees. I used the same window Zane found and used earlier where he got 326.8 for the tall one. This grove also has other trees over 300 feet. It was very dark and shady in there. Seemed to be rather dense forest for the soutern range.

The tallest redwood or any tree of any species known to grow south of SF Bay (the region considered the southern range for the species) was Old Tree at 305 feet. Centurion, a eucalyptus regnans in Tasmania was 326.9 feet (99.6 meters) when last measured by Steve Sillett by direct tape drop a few years ago. Centurion could be taller by added growth since the 2007 measurement, but this is not yet confirmed.

As usual, Zane continues to shatter tree height records.

Zane's spot-on measurements for these two redwoods would indicate to me that his other tree height measurements are accurate too.

Re: Tallest Tree South Of SF Bay Confirmed


Steve Sillett and Jim Spickler climbed the tall redwood in Big Basin State Park recently. Their direct tape drop measurement was 100.01 meters, or 328.12 feet. Zane and I missed the very "tippy" top of the highest leader, which was obscured a little from our view. Nevertheless, we got fairly close to Steve's direct tape drop measurement. His interpretation of ground level was a little lower than ours though.

This redwood is the only known 100m southern population redwood (those south of San Francisco) and the only known 100m+ tree south of 38 degrees latitude. Centurion, a eucalyptus regnans in Tasmania was last measured at 327.6 feet in 2006. This tree may, or may not be over 100 meters now.

"The President" giant sequioa, SNP, CA

The December 2012 issue of National Geographic Magazine features as its cover story an article on "The President," a giant sequoia in Sequoia National Park California.


The text of the article can be viewed online, but by doing so you will miss some the beautiful images from the print version of the article and a large scale poster of the entire tree also available in the print edition. The article is by David Quammen, and the photographs are by Micheal Nichols who did the December 2009 portraits of giant redwoods in National Geographic


The web version of the poster is here:

The article describes Steve Sillett's teams effort to map the detailed branch structure of one of the world's largest trees by volume. Will Blozan was one of the team hired to do the mapping.

NOt all the redwoods have been LiDAR'ed. The world's tallest tree may still be out there !

Re: The Floyd Otter Sequoia, third largest?? Never heard of

Floyd Otter is on the hillside just above King Arthur in Garfield Grove. Wendell Flint never got the chance to measure the Floyd Otter volume with transit. Bob VP has not measured this tree as far as I know. I have never seen it.

This June I plan to go in there with a few friends and put the Solo RT on it's massive bole for a volume estimate. Get good photographs. Generate a point cloud map of the lower trunk to get further refine volume estiamte. The fire scar creates an estreme "out of round state". Radii type models may not properly account for the missing wood.

Hope to have a volume estimate on Floyd Otter in about 4 months.

White Fir

Hi All,

Mark Rouw discovered a big white fir near the bottom of Wolf Creek Pass 15 years ago. He revisited the tree on this years WNTS rendezvous and confirmed that it had grown. He gave me directions to it. So on leaving Durango, Monica and I stopped at the foot of the pass and went up the Windy Pass Trail 0.72 miles and there it was. Here are two images.



So how big is it? Well I got 13.9 feet around and 142.0 feet in height. So Mark has the NTS height record for the white fir. So far our Colorado list of tall species is as follows. This is off the top of my head.

Species Height Girth Measurer

Doug fir 163+ 17.0 Mark Rouw
Ponderosa P. 160.3 9.3 Bob Leverett
Colorado Blue 160.2 8.6 Bob Leverett
Englemann S. 142.5 10+ Bob Leverett
White fir 142.0 13.9 Mark Rouw
S.W. white pine 127.0 6.3 Bob Leverett
Narrowleaf CW 114.0 Bob Leverett

Mark also has the record for the subalpine fir and quaking aspen. I need to get the figures from him on them. But as you can see, the Colorado tall tree list is starting to get pretty darned impressive.

Albinism in a Sitka Spruce Sapling

Deep in the redwood forest in Prairie Creek there are, what appears to be, several albino Sitka Spruce saplings growing near one another!

Coast Redwood bigger than average

Found a particularly large Coast Redwood with Chris Atkins, the past few days. I won't be listing the dimensions or name. It appears to be the largest single Coast Redwood trunk known. More about it and other redwoods found are on the following link:

Read more at >

One reason for omitting the trunk diameter in this post, is it will be tape wrapped again, possibly climbed and measured. We plan to explore more this summer, in several parks. Even repeating areas that have been explored. Its evident how possible it can be to pass by something this big first time through an area.

Updates will be added to that page, or possibly here in replies following.

New dbh champ for SESE

On May 15, 2014, Joseph Hall and I discovered a giant single-stem redwood while bushwhacking through a remote area in Northern California. Our preliminary measurements suggested this SESE's diameter was larger than Lost Monarch.

For independent verification, I returned to the tree with Zane Moore and Luke Adams. The difference between upslope ground level and downslope ground level was 16', so we painstakingly performed an even tape wrap at upper ground level. The result was 23.95'. This measurement was treated as 8' above average ground level, and Zane then plugged in Bob Van Pelt's functional dbh equation. This yielded a functional dbh of 27.2'.

In our opinion 27.2' is a conservative number, because the functional dbh equation accounts for an average SESE taper, and the taper between 4.5' and 8' on this tree is well above average.

We can say with confidence that it is a new dbh champ for redwoods.

Joseph and I have named the tree "Crocodile".

259' - New California Height Champion For Ponderosa

Yesterday, while hiking through some prime forest along Eagle Creek (Shasta-Trinity National Forest), I encountered a towering ponderosa. It was tapping a spring on a 30 degree hillside. I left my Trupulse laser in my backpack the entire day until this point as I as I saw nothing but scrappy trees. But then I dropped into this shady glen and the trees became exceptional.

This is one of many extremely tall ponderosa pine that grow in the intermediate ranges, which is the mountain range between the Coast Ranges and the Sierra Nevada or Southern Cascade Range in extreme Northern California and Oregon. The intermediate ranges of northern California have large areas of prime forest in the 4000-5000 foot elevation band with deep top soil. Unfortunately this region was more heavily logged than the Sierra Ranges. Nevertheless, exceptional specimens remain well hidden in a few isolated pockets here and there. That tallest ponderosa known, 268.3' also grows in the intermediate ranges which extend into Southern Oregon.

This tree has a dead top and was likely pushing 270' at one time.

Statistics for tall ponderosa pine:

Height: 259 ft
cbh: 16 ft

new dbh champ for SESE (and other records)

On May 8th, I found a redwood with a monster base in Redwood National and State Parks. My initial numbers suggested a new champion for both SESE dbh and ground perimeter.

On May 20th, I returned to the tree with Zane and Steve Moore for verification and further study. Here are the numbers:

Dbh: 29.2' (8.9m) functional dbh
This bests the previous record by 1.8', making that mythical 30' redwood seem like a real possibility!

ground perimeter: 116' (35.36m)
Another record for SESE, and it even tops Boole by 3'!

ground axis: 43.3' (13.2m)
To my knowledge, this is the longest single stem axis of any tree on Earth.

official ground footprint: 864 sq feet. (80.3 sq m)
Record for SESE

Initial volume estimate based on lower tape wraps and relescope readings from a single angle: 27,959K
Basically, the main trunk is in the ballpark of 28K, a much higher number than I initially expected. It's not particularly tall or thick on the upper trunk.

Initial height estimate: 254' (77.4m)

There is also reason to believe this tree is a candidate for oldest SESE. Further study would be required.

As some of you know, I enjoy assigning names to notable trees. This tree goes by the name of "Jupiter".

Special thanks to Zane and Steve Moore for their help, and for an awesome day in the forest!

I'll keep everyone posted, as Jupiter is studied further.

Re: Measuring Fusions


Zane Moore's approach to evening the playing field in big tree volume competitions may have applicability to the more customary point competitions by showing us the way to reducing the circumference points from fused trunks of coppice forms.

If we have a tree that we definitely believe to be from one root system, but subordinate trunks have developed from the root collar and fused with a main trunk, each up to some height, do we exclude all of subordinate trunks, include those that make contact with the main trunk at 4.5 feet, or roll dice? Remember, here we assume on tree - just a complex form. The following formula discounts subordinate stems and is set up for basic reticle measurement of the diameters of each stem an the point of splitting from the main trunk plus the measurement of the whole structure at 4.5 feet or lower if that is where they all come together. In the formula below, Di represents the ith diameter where i=1 is for the main trunk. si=height where the ith trunk splits from the main trunk, h = total height of main stem to top of tree. s1=h to include the whole contribution of the main stem, n =total number of stems including the main trunk.


Note that this approach follows Zane's lead. It is algebraically equivalent to: computing the cross-sectional areas of each stem at the point of separation and the apportioning the total cross-sectional area at 4.5 feet or lower, if that is where they all are fused, between the n stems. Then the areas of the subordinate stems are discounted by the factors si/h, remembering that s1=h. The areas of the main and discounted subordinate stems are added together and then the equivalent circumference computed from that combined area. The process can be expressed in terms of diameters since my assumption is that they will be measured via the reticle, except possibly for the combined group at 4.5 feet or lower. The composite measurement may be done with a tape in terms of circumference and then converted into equivalent area based on a circle.

When I return to Massachusetts, I'm going to test the formula out on some eastern deciduous trees. We owe Zane a vote of thanks for pointing the way to possibly solving a thorny problem that has heretofore had no satisfactory solution.

Sugar Pine Height Record Oblitterated

I measured a super tall sugar pine today in the western foothills of the Sierra Nevada ranges. Site elevation was 4600 feet which is the prime elevation band for the species.

The height of this tree is 273' feet !!

The diameter at breast height is 7.7 feet.

This is now the tallest known pine in the world, even topping the Yosemite Giant and Phalanx. Oregon now loses its status as having the tallest pine tree. The height record goes back to sugar pine, not ponderosa.

More Big Trees To Report From The Sierra Nevada

In late July, Mike Hanuschik and I visited the Central & then Southern Sierra Nevada for a weekend in search of extreme trees. We explored the El Dorado National Forest , Freeman Creek Basin and Dorrington-Calaveras area. We also checked out the Whelan Sugar Pine. This tree is unbelievable !

See attached photographs.

Whelan is 20% bigger than its closest rival in terms of volume with about 9,000 cubic feet of trunk volume. At 50 feet off the ground, Whelan Tree is still over 9.4 ft in diameter.

Also, this tree was rumored to be dying from bark beetle attack but I saw no such evidence of this. I counted only 1 possible bark beetle "pitch tube" on the entire lower trunk surface. The top of Whelan is looking vigorous as well. New height is 208 ft.

John Muir was the original big tree hunter and he considered Whelan to be one of the largest sugar pines, if not the largest...see attached pictures of John Muir under Whelan on or about 1900, Camp Sugar Pine Administrator Megan and Mike Hanuschik under the Whelan.

In the same general area we located a gigantic ponderosa pine that was 7.7' dbh and another sugar pine that was 9' dbh in the Northern rim of Calaveras Grove.

On day 1 we also explored the El Dorado National Forest for big pines and we found a few. We also checked out the new AFA champion ponderosa pine in El Dorado National Forest. The top of this tree just died recently...see attached pictures. This tree is a co-champino to the big ponderosa in Trinity County in terms of AFA points. The Trinity ponderosa has a bulkier trunk and is a little bigger in volume at about 5,100 cubic feet vs. 4,650 for the El Dorado Ponderosa. Towards the end of Day 1, we measured another large sugar pine at 8.7' dbh and 5,200 cubic feet of wood...big enough to make Bob Van Pelt's Forest Giants Book.

On Day 2 of the expedition we explored the Freeman Creek Basin in Sequoia National Forest in search of tall giant sequoia. We found no giant sequoia over 300ft, but we did manage to find a super sized specimen off the beaten path that has no apparent name. Its dbh was 26.5ft and this was taken on the high side ! The volume of this tree is surely over 30,000 cubic feet. Nearby is another giant of near equal size.

No world records were found in our last Sierra expedition, but we did find some notable trees. See attached pictures.

Sempervirens, even after death...

I came across something pretty fascinating yesterday in Big Basin. Two old growth trees have fused into each other but not before a large log had fallen between them. The trees continued to fuse for....a very long time around this log. Obviously the logs of most species would have decayed long before the trees fused. It shows how long even dead wood lasts in these forests and it also shows how some trees that appear as single stem are actually multiple trees. One photo shows the log from the other side where the tress have not fused yet.

The only example of a weeping sequoia living in the forest?!

In contrast to the Tunnel Tree, the record wide giant sequoia in my previous post, follow photos of a slender weeping sequoia growing in Alder Creek Grove, according to Wendell Flint: “the only living example of a weeping sequoia living in the forest. Other weeping sequoias are cultivated in nurseries. The branches of this tree fall directly downward, so that the tree is a skinny column. It is a juvenile tree, and since it is so rare and so easily harmed, I’m not saying where it is.” (To Find the Biggest Tree, 2002, Alder Creek Grove chapter, page 79). Wendell Flint credits his cousin and hiking companion Robert Bergen for spotting the weeping sequoia.

As with the Tunnel Tree I haven’t seen photos of this one before. Hope you find them interesting. Giant sequoia adjectives such as majestic seem out of place when looking at the weeping sequoia. I read in The Giant Sequoia of the Sierra Nevada (1975) that a specimen in Roath Park in Cardiff, Wales was labeled “the ugliest tree in Britain” :)

Have you seen or heard of a weeping sequoia growing wild someplace else?
Or could this be the singular one?

New Tallest Sierra Lodgepole Pine


Today, I had the chance to head over to the other side of Calpine Pass, to the north of Calpine, CA (where I live), to a magnificent Lodgepole Pine grove ( Pinus contorta var. murrayana ). There are many extremely tall specimens in the grove, which spans both sides of CA-89 and covers nearly 50 acres. I have had my eye on the area for some time, and I got the chance to measure a particular eye-catcher today. The tree is 131.10' tall, a new world record by 7 feet! It does not appear, however, that this tree is the tallest in the grove. The area has very good chances for producing a 140' class Lodgepole.

BlackFox Sugar Pine, Possible Volume Champion

I recently visited the BlackFox Sugar Pine from Michael Oxman's climbing video posted on youtube.

The tree is claimed to be 250' tall and 9' diameter. This behemoth is indeed over 9' dbh and it has a slow taper. The top is dead but completely intact. Despite being 52 feet shorter than reported I was still not disappointed. Not sure why the loggers left this lone giant standing ? Perhaps due to fear of rot so cutting the tree would be a safetly issue ? Perhaps as a landmark, heritage type tree, similar to the Collins Pine ? Or perhaps as a seed tree.

This is a rare giant sugar pine from the Cascade Ranges, which had some of the biggest sugar pines of any place but were mostly logged.

Here are the stats on BlackFox sugar pine:

height: 198 ft
dbh: 9.17 ft
trunk volume: 5339 cubic ft
d50: 7.2 ft

Despite its stoutness, the volume is nearly equal to my estimated volume of the newly appointed and much more slender American Forests champion in Calaveras County. With the error range in my relascope measurements I would say this tree could be even the largest by volume. Climbing and tape wrapping this tree's trunk and all significant branches would be the best way to prove which is really the largest known sugar pine.

Current volume and American Forests point champion sugar pine:

height: 241 ft
dbh 9.1 ft
trunk volume 5,486
d50: 6.4 ft

New Champion Mahogany FOUND


Yesterday, I went with my grandfather Bill Harnach on a trip to meet a local named John Preschutti. John knew where to find a huge Mountain Mahogany, that we figured might become a new National Champion. We drove several miles down a back road to a small drainage, which we hiked up. Upon reaching the top of a ridge to the west of the drainage, we found the Mahogany. This tree is huge: 12'0" CBH, 22' H, 36' averaged crown spread! It is huge! The AFA Point total was 175 Points, making it the largest of the three Co-Champs!

This is the first tree I have measured as the newest member of the American Forests Association's National Cadre of Expert Tree Measurers. I was made a member yesterday after Michael Taylor sent out a "thumbs up" email to Bob Leverett, Don Bertolette, Matt Ritter, and the staff at American Forests.
