I know this site is normally reserved for tall and giant Eucalypts, however, I couldn't let the opportunity of showcasing this old relic slip by. While bushwalking along Bluff track in Victoria's High Country between Mt Magdela and The Bluff at around 1600m in altitude, we came across this amazing snow gum Eucalyptus pauciflora subsp niphophila. It is perhaps the gnarliest snow gum I've ever seen in many a trip to the area - It has been named the 'King Billy Tree' and has Heritage listing on Victoria's National Trust register. Having no laser or tape measure with me, I didn't obtain any girth or height statistics - but the National Trust lists it at 9.4m girth and a wind restricted 6.7m tall! Snow gums at this altitude grow very slowly and are often covered in snow for 3-4 months of the year. They are also subject to extreme winds and bushfires. Miraculously, this locality had somehow missed the serious bushfires in 2003 and 2007 that burnt tens of thousands of hectares of alpine snow gum country. Nevertheless this tree appeared centuries older than all its nearby unburnt mature companions and all the other snow gums we saw over the three days of hiking.

Autumn in Tasmania's tall forests
Autumn is an ideal time to visit Tasmania's tall forests with often stable weather patterns that include cool nights, crisp mornings, calm days and excellent light for photos. So I took the opportunity to team up with some old friends to check out some special trees and also follow up on some potential tall trees identified by LiDAR.

An unexpected surprise greeted us when we opened the bin at the Arve River Camping ground: a spotted quoll snacking on discarded chicken!

R.I.P Wayatinah Giant
When walking up Heald Spur in January 2017 I noticed from afar that the familiar crown of the Wayatinah Giant was missing from the skyline. This tree had been severely damaged by a fire in 2010. (for comparative photos see http://tasmaniasgianttrees.weebly.com/florentine-and-upper-derwent.html ) Although growing 50m above the road, it had collapsed and tumbled a little way downhill before falling and the top section had shattered, completely obliterating a section of the regrowth below the road and 80m from the tree base. This tree was pretty special to me as it was the first truly giant tree I found in Tasmania in 1992. It was 17.4m in girth and was 85m tall - it's trunk remained massive for a long way up, with the tree having the largest diameter for a living eucalypt at the 45-50m height range where it was still 6m in girth.

Introducing some 'new' Tasmanian giants...
In January 2017 a number of amazing trees were uncovered when searching through a few areas where there had been LiDAR hits above 85m. 'Countess Basie' is over 16m girth and is very photogenic having an unusually clear view to its base. 'Brutus Maximus' is an 86m tall Eucalyptus regnans and while it has large rather than huge girth of 13.8m, it still may push 280m³ in volume due to its huge, slow tapering trunk. 'Shield Maiden' at 17.4m girth and 87m tall is a show stopping, classic 500 year old Eucalyptus regnans, clean of branches for a considerable way up on its southern side. However, these trees were almost upstaged by a pair of ancient Eucalyptus obliqua trees growing 30m apart. 'Obnificent' has a redwood like lower trunk and is 14.8m girth and around 77m tall. Its neighbour 'Obli-Wan Kenobi' has a slightly larger girth at 15.8 and an amazing gnarly fluted trunk and complex crown.

The gnarly trunk of 'Obli-Wan Kenobi'
An eight hour off track walk through the gullies and ridges of the headwaters of the Upper Franklin river in early January 2017 has uncovered some very gnarly giant old trees. As is the case with most old Eucalyptus regnans in the Strzelecki Ranges, all of the 300-400 year old trees we saw had long ago lost their original crowns. Although some, like 'Octopia' (photographed below), had re-developed a complex lower branch structure and a full crown. While older trees were scattered throughout the area, 'Octopia' was found in a small patch of very old forest which produced all the largest girthed trees of the day: 'Benedict' 14.3m, 'Franklinstein' 13.2m, 'Octopia' 13.1m with many more over 10m. This part of the Strzelecki Ranges is also the only place on earth where the otherwise very rare slender tree fern, Cyathea cunninghamii, is actually abundant and was seen thriving in all the gullies we traversed.

Google earth helps locate big trees in logging regrowth
Recent improvements in the quality of the satellite images on google maps in some areas has helped me locate some impressive old trees amongst 20-30 year old logging regrowth off Nolans Road near Toolangi. The largest tree located I called 'Boss Nolan' - it is 10.5m girth but has a slow taper and a very large lower 25m of trunk including a 'fire window' about 20m up. In all there would be over 40 old trees surviving amongst the regrowth in the area and as they all have survived both the 1939 and 2009 fires, virtually all of them having fire scars and broken, decaying tops.
Above: 'Boss Nolan' crown and base

A different concept of time!
Two photos of 'Velvetine' taken 25 years apart show how little the tree appears to have changed in the time I first saw it - unfortunately the same can't be said about the person in both photos!
Giants survive Kobiolke Fire
A fire that started in a nearby logging coupe in February 2015 impacted on a number of old growth trees growing along Kobiolke Fireline in the Latrobe State Forest near Powelltown. Even though the fire killed most of the understorey shrubs and wattles, the steep southerly aspect of the forest meant the fire did not burn fiercely enough to kill the old E. regnans trees that make this such a special place. Below are a few photos of the the 11.7m girth, 65m tall 'Belladonna' taken after recent (June 2016) snowfalls.
1939 regrowth reaching for the sky
In mid-May I re-measured the tallest known 1939 regrowth tree 'Ferguson's Ghost'. The laser measurement indicated the tree is now at least 85m tall.The tree is in excellent health and shows no ill effects of having an under-storey burn in February 2009 (the fires killed a number of nearby trees as can be seen in the photo below) Late autumn is a great time to visit the mountain ash forests, the temperature is generally cool, the forest is damp and lush and there is a profusion of different fungi species that can be seen.
Victoria's largest trees paper published in the Victorian Naturalist:
Grant Harris and I have had a paper on Victoria's largest trees published in The Victorian Naturalist, April 2016, volume 133 (2). This is a paper 25 years in the making! We are grateful to the Victorian Naturalist for giving us permission to reproduce it below:
Giant Tasmanian Trees
In late December 2015 some previously unknown giant trees were discovered near 'Rullah Longatyle' the giant Blue Gum off Johns road in the Esperence Forests in Southern Tasmania. This remnant patch of forest is unusual as it contains giant Eucalyptus regnans, obliqua, delegatensis and globulus as well as large examples of myrtle beech and sassafras all growing within a 3 hectare area. Pictured below is Yoav Bar-ness next to 'The Spiral Claw', a giant Eucalyptus obliqua. Further examples can be seen at http://tasmaniasgianttrees.weebly.com/esperence-and-dover.html
Big Grey Gum found
A large grey gum Eucalyptus cypellocarpa has been discovered in the Toolangi State forest by local conservationist Harley Sanderson. Named 'Ramah' the tree is 10.15m girth and 54m tall and boasts an impressive lower trunk as the picture below demonstrates. With an estimated volume of around 150-165m³ the tree will likely rank in the top 2-3 grey gums known. Hopefully the discovery of this tree and other nearby large, old hollow bearing grey gums will mean that planned logging in the vicinity will not proceed.
Double Decker Dindi not able to be saved
A recent assessment (August 2015) of the 87.6m tall tree 'Double Decker Dindi' revealed a further deterioration of its condition. The taller uphill fork is now leaning into a neighbouring tree and the split from the fork 14m up now almost goes right to the ground. In this condition it is not able to be saved using bolts and cables. It will be interesting to see what will happen to the downhill side fork once the uphill fork falls right away. At the moment this fork is not leaning and is around 86.5m tall.
Blackbeard loses his crown
Until recently 'Blackbeard' was regarded as Victoria's largest living tree with a volume of 245m³.However, a winter storm back in 2014 sheared off part of Blackbeard's upper trunk. Recently I went to assess the damage and found that the tree was now 57m to where the trunk was broken - a loss of 16m of trunk from it's original height of 73m. While this part of the tree was not massive it still meant a loss of around 15m³ of wood volume, so the tree is now around 230m³ and ranks about 4th or 5th in the state.
The dead top of 'Blackbeard' taken in 2010 - this whole section has since fallen, taking a considerable amount of living branches with it when it fell.
Hidden treasures of the Otway National park
In late June 2015, an off track search of forest in the Great Otway National Park uncovered some wonderful 'new' giants. At least twelve trees between 12m and 14.9m girth were measured and many more in the 10m+ girth range. Highlights of the trek included the discovery of 'Grumpkins' with its enormous lower trunk, the 'Vim Vitale', possibly the equal largest Eucalyptus viminalis in the state and 'Sammy Spreadwell', with a girth of 14.9m. Off track walking in the Otway ranges is often a nightmare with devilishly steep and slippery gullies combined with dense vegetation making progress very slow. However, in this particular case, the fact that we covered only 1.5km in 6 hours was more due to the fact that there were so many great trees to measure and photograph because the terrain, vegetation and weather were pretty friendly by midwinter Otway standards.

Climbing the Lonely Tanjil Titan,
In late March 2015, a dedicated team of four climbers lugged their packs 4km up an overgrown track to climb and measure the Lonely Tanjil Titan - a huge mountain grey gum, Eucalyptus cypellocarpa, located a few kilometres east of the tiny locality of Tanjil Bren. We found the tree had decayed significantly since I first noted it in 1992. I re-measured it in 2006 where the top of the trunk was dead but still reached 64m tall. Now its main trunk is broken at about 33m up, however, a huge but dead original branch that is still hanging onto the shell of the trunk rises up to height of 44m. Despite the loss of about 25m of the main trunk, the tree still contained 163m³ in its reduced state due to its stove-pipe like lower trunk. This makes it the largest measured Eucalyptus cypellocarpa, however, the huge mountain grey gum at Ellery Camp has not been accurately measured for volume (see East Gippsland). Interestingly, once again there was an abundance of arboreal lizards that had made their home high up in the canopy of this aged hulk of a tree.

Good news ...... and bad news
The good: Today, March 8th, Tom Greenwood and I went back to Double Decker Dindi to climb and measure it. The tape came down and the tree came in at 87.66m tall – currently the tallest living measured tree in mainland Australia!
The bad: The tree has a major and apparently recent split at its bifurcation that runs for about 6m down from where the two trunks originally separated (see photo below). It is unclear how long the tree will remain upright – there is a possibility we could get a team together and cable together the upper trunks and then perhaps bolt the tree at the split.
The Tallest tree in Mainland Australia – A new Contender!
On February 8th 2015, I measured a ‘new’ contender for the title of tallest living tree on the Australian mainland. This tree appeared on old (2007) LiDAR mapping from Vicforests at over 84m tall, but no one had actually gone to the tree to get a more accurate height using a laser. This regrowth tree with a healthy live top is located in the Toolangi State Forest, on the lower section of a gentle ridge not far from a small gully and creek – it is around 1km off a primary gravel road. This mountain ash tree is a stunner – forking at around 20m up with both boles remaining pretty clear for a long way up. Using the photo below as a reference, the left fork was lasered at 87m tall while the right fork was at least 86m tall. My companion on the day Pat, while scratched from some of the wire-grass thickets we had to walk through, definately approved of the name I have given the tree: ‘Double Decker Dindi' (see second photo below). Double Decker Dindi's DBH is 1.62m making it highly likely that the tree originates from fires in 1919, like other large regrowth Eucalyptus regnans trees in the vicinity.
'Double Decker Dindi' each fork is over 86m tall

'Prince William' tree over 85m tall
In October 2014 the tallest known tree in the patch of forest below William Ricketts Sanctuary off the Mt Dandenong Tourist Road was climbed and measured by Tom Greenwood and Grant Harris. I had lasered this tree from the ground a number of times in the past - at 82m in 2001 and 84.5 in 2011 - and was pleasantly surprised with the current total height of 85.68m which makes it 5th on the mainland's tallest measured, living trees. The site appears to be exceptionally fertile with at least 5 other trees in the stand exceeding 80m in height with 2 of them having a girth greater than 8m. As the morning light filtered through the surrounding forest I took the photo below.
We were also visited by some noisy rainbow lorikeets (Trichoglossus haematodus) high up in the canopy (photo Grant Harris)
Uncovering Strzelecki giants
A September 2014 expedition to uncover giant remnant Eucalyptus regnans in the Strzelecki Ranges unearthed a half dozen previously unknown large trees between 11m and 12.5m girth - the largest in volume was the 'Ridgie Ruin' pictured below. It had a probable wood volume over 170m³, despite it being a hulk with a broken trunk at about 33m up.
'His Royal Antechinus' a giant home for greater gliders
In late April 2014 a team of climbers measured the newly named and discovered tree, 'His Royal Antechinus'. The tree turned out to be considerably larger than first thought and, at 206.5m³, it now ranks as the 10th largest tree measured in Victoria. What was perhaps more impressive on the day was the appearance of two greater gliders (Petauroides volans) in the tree. One of which we had the privilege of seeing glide from the top of the tree down to the lower branches. The other stayed high up on a small outer branch, warily watching the activities of the strange noisy creatures who had interrupted his daytime sleep.

Skinks discovered living high up in old mountain ash trees
Environmental scientist Grant Harris has written up a paper on our sightings of Spencers Skink in very large, old Eucalyptus regnans trees in the Central Highlands. Furthermore, the editors of the Victorian Naturalist journal have gratefully given us permission to publish the paper below.
'New' Toolangi Giant
Recently, Toolangi naturalist Don Butcher measured a large Eucalyptus regnans tree, located in the Toolangi State Forest. It came in at 14.1m girth and 65m tall. Its trunk was broken at around 55m up; nevertheless it was still quite healthy with a fully developed mid-trunk crown composed of many large branches. The tree has a fire scar on its northern side, not from the recent 2009 fires but more likely from the 1939 bushfires and a mostly clear bole for the first 30m. We have named the tree 'His Royal Antechinus' after a small male of the species was found dead at the base of the tree - Presumably having 'mated' himself to death as is the fate of all males of the species!

Tasmanian tall tree LiDAR finds
In 2013, Forestry Tasmania’s ongoing LiDAR* survey of State Forests uncovered nine potentially 90m+ trees in the Huon and Styx areas. In December 2013 I was able to check out 7 of the LiDAR hits - of which 6 turned out to be genuinely tall, old growth Eucalyptus regnans trees between 88m and 92m in height. The most impressive tree was a 92m tall tree deep within the Kermandie block. This wonderfully formed tree is branchless for 45m and has living top rising above an original crown. This is unusual in this area where most of the very old trees have broken crowns and are composed of epicormic or secondary branches which form lower on the trunks as a response to crown dieback or loss higher up. I have nicknamed this tree ‘Kermajesty’. Other impressive trees included a 90m tree off Arve spur 2 and an 89m tall tree high up on the Maydena range.
* LiDAR is short for Light Detection and Ranging. It is a technology that uses a stream of laser pulses, in this case taken from an aeroplane, to generate three dimensional structural data of the landscape you are flying over.
Giant Shining Gums climbed
In late November 2013, two giant shining gums, Eucalyptus denticulata, were climbed and their volumes measured. The largest, 'The Whitelaw Tree' came in at an impressive 229m³ in wood volume. This makes it the 5th largest tree in Victoria. Its girth was 14.9m at breast height while its trunk was broken at 50m. The second tree, named 'Hairy Maclary' due to its very shaggy appearance, contained 187m³ in trunk wood volume. These shining gums are growing at 1000m asl: winters are long and cold with regular snow falls, summers are mild. It is therefore highly likely they are between 450 and 500 years old. Below, my climbing companions, Grant, Julia, Ewan and Dan are enjoying doing the final tape wraps on the Whitelaw Tree.
Wotan's Spear height confirmed
In late October 2013, 'Wotan's Spear' was climbed by Tom Greenwood and Grant Harris and its height confirmed at 85.2m. The photo below shows a view of the magnificent 1926 regrowth forest taken from the tree.
Giants in the Strzelecki ranges
A recent (September 2013) off-track trip deep into the Gunyah area of the Strzelecki Ranges uncovered a surprising number of ancient mountain ash trees with very large girths. While most of them had lost their tops generations ago, what they lacked in height they made up for in their gnarly, buttressed bases, often lined with moss and filmy ferns. The biggest tree of the day came in at an impressive 15.7m girth, making it one of the largest bases in the State.
'Dr McCavity', while only 45m to a broken top, makes up for it's lack of height with a girth of 15.7m and some unusual features, including the 'toothed' cavity for which it is named and what appears to be a suppressed regrowth tree growing out of the front buttress (Photo: Grant Harris)
Kalatha Tree walk
The walking track to the Kalatha Giant was officially opened by Mark Butler, the Federal Minister for the Environment on Sunday 28th August 2013. The well graded 250m track forms a loop and takes visitors both above and below the tree. I first noted this tree back in 1992 and it is fantastic that many people can now easily appreciate this magnificant mountain ash tree.
Directions from Healesville: Take Meyers Creek rd, head north 10km through some fantastic 1926 regrowth mountain ash forest along Meyers creek scenic Reserve. Turn right into Sylvia Creek Rd, travel along 10km, passing WirraWilla Rainforest walk and just past Tanglefoot Picnic ground. take Kalatha rd on the left. The car park for the walk is about 1.5km down Kalatha Road.
Tall tree measurement
In early July 2013 I measured a tree along the Tomahawk Creek, Beenak, at over 85m tall. This tree is 2km further upstream from the 'Bunjil's Spear' tree and associated patch of very tall trees. The tree is superbly formed and only about 1.2m in diameter (see below). My companion on the day, Brian Walters, gave it the evocative name 'Wotan's Spear' It appears to be of 1926 origin and hopefully has many years of growth left in it.
I recently remeasured a tree I had originally noted back in 1992 - I called it the Fireline Beauty and it grows off Kobiolke road, south of Powelltown. It is the tallest known of the trees that exceed 175m³ in volume. The tree is on a steep slope and the height is around 83m - a number I hope to get more accurate when the tree is climbed.
Large Shining Gum
An impressively large shining gum, Eucalyptus denticulata, was found not far from the Whitelaw tree (same species). It grows at around 1000m above sea level. It is 10.7m girth and about 58m tall. It has an incredibly gnarly and shaggy appearance - so I have named it 'Hairy McClary'.
