Jan 2011 Newsletter - 23rd Jan 2011

Jan 2011 Newsletter Dear Notable Tree Enthusiasts,

The New Year is well underway with many of us here in New Zealand still in holiday mode.  2010 ended on a high following another successful joint NZAA/NZNTT conference in Auckland where attendees enjoyed the mix of social gatherings held over a comprehensive 3-day programme.  Kauri Dieback was the subject of the free public Tane Mahuta Lecture where Dr. Nick Waipara presented the audience with a grim account of the potential loss of our iconic tree to Phytophthora taxon Agathis (PTA).  This was, in effect, a timely reminder of the importance of recording our current tree heritage so that, in the event of decline or loss, future generations can at least marvel at what we were able to experience.

There have been a number of interesting trees added to the database in the past few months.  In addition to this we are pleased to release more improvements to the database.  More below but first,

A note about measuring the girth of trees on slopes

In the last newsletter we talked in general terms about measuring tree girth.  Trees growing on sloping ground create problems in relation to where to place the baseline of your tape to determine breast height (1.4m).  Do you measure from the bottom of the slope at ground level, or on the top side?  For consistency and accuracy we prefer breast height to be taken from the mid-slope position.  To do this, sight down the centerline of the stem to where it comes in contact with the ground.  Place the baseline of your tape here and then take your 1.4m measurement.

On very steep slopes you may need to measure the tree above 1.4m to clear the ground on the topside.  As examples, tree 778 was measured at 2m and tree 779 was measured at 1.6m.  In the notes a reference has been made to the height of girth relative to the topside of the tree.  This provides good reference information to other tree measurers who may re-measure the tree in the future.

register.notabletrees.org.nz/tree/view/779

An update – The Pahi Moreton Bay fig in Northland

This tree was considered by Bob Burstall in 1971 to be the finest looking specimen in the country.  Updated measurements and images have been recently entered into the database – and, from the new information, you can see that Burstall’s comment is still true today.  Check out register.notabletrees.org.nz/tree/view/501
A new listing of the Moreton Bay specimen at Monte Cecilia Park, in Hillsborough, Auckland, shows that this tree is still the largest tree of this species recorded in New Zealand register.notabletrees.org.nz/tree/view/783.  To view the full potential of these trees go to the Australian Big Tree Register www.nationalregisterofbigtrees.com.au/listing_view.php

New listings
Two standout trees have been listed along with many other new trees. In brief – firstly, the Caucasian fir (Abies nordmanniana) at Mararewa, near Tapawera in Tasman is an exceptional specimen – particularly since it has come to light that it is the largest recorded specimen outside its natural range register.notabletrees.org.nz/tree/view/696 .  The second tree is the Coulter pine (Pinus coulteri) located at Otekaieke, North Otago.  The institution where this tree is located has a very interesting history.  Despite the tree record being dated 1984 (S.W. Burstall) it is still the largest known Coulter pine in the world.  Images on the Internet of the Campbell Park Estate appear to show that the tree still exists and one wonders at how much it has grown over the past 30 years. register.notabletrees.org.nz/tree/view/776

New features
We have had lots of feedback regarding the new database features reported in the last newsletter.  The map feature and tree dimension format on the search results table have been well received.  The ‘recent changes’ report, located on the database home page, has also been very popular.  Thank you all for your feedback.

Text Search
The tree notes are now fully searchable.  This development was made possible by the Ministry for Culture and Heritage and the Trust thanks them for their assistance and support.  The feature will be of particular interest to historians and writers.  To use this feature select ‘Text Based Search’ located at the top of the search page.  Enter your key word/s and click ‘Enter’. For example, to see how the feature works, try searching ‘Prince or ‘World War’.


Quick Search By Region
You will note the new map on the home page of the database and the ‘drop down’ for each region in New Zealand.  This enables users to quickly search trees listed within given area.

Regional Sponsors
Users will notice sponsor banners showing up on the tree file pages.  The Trust is pleased to offer individuals and organisations the opportunity to support the project and in return gain some recognition.  Anyone wishing to sponsor all the trees of a particular region in New Zealand should contact the Trust via the website.

Mark Your Calendar!

The NZNTT will be hosting an informal information event at Cornwall Park in Auckland on Friday 18 February.  A brief presentation on using the database and listing new trees will be given.  This will be followed by measuring trees in the field. Bring a lunch and come join us in the park.  Meet at the Education Room at the Cornwall Park visitor’s information centre at 9.00am.

Thank you to those that have sent in updates and new tree records.  For those of you who would like to get in on the action to update tree records or register new trees, simply go to the website and follow the instructions.


Kind regards,

Sept 2010 Newsletter - 24th Sep 2010

Sept 2010 Newsletter Dear Notable Tree Enthusiasts,

We have had some exceptional trees added to the database in the past few months.  In addition to this we are pleased to release several new database features that we have been developing.  The new features will enable easier interpretation of data and also make it easier to find the latest tree updates and new listings.  More below but first,

A Note About Measuring Tree Girth

Whilst tree girth or circumference is generally taken at 1.4m in New Zealand (C or GBH) certain latitude is required when measuring trees that deviate from the norm.  Trees that have huge swollen buttresses should be measured above the buttress and this height noted.  The following is a good example register.notabletrees.org.nz/tree/view/695  Additional measurements can be taken of the buttress for the record.

Low branching trees can also create challenges for measuring GBH.  When measurements are unduly influenced by branch swellings, or even burls, then take your measurement above or below the swollen area and record this height.  A girth height of 1.15m was recorded in this example register.notabletrees.org.nz/tree/view/665

Remember ‘less is more’ when it comes to taking girth measurements.  Slide your tape around to obtain the smallest measurement then record the height so that subsequent records can be taken from the same reference point.

In the next newsletter we will talk about measuring girth of trees growing on sloping ground.

An Update – New Zealand’s Largest English Oak

For many years the Rotorua ‘Arawa oak’ has been considered New Zealand’s largest recorded English oak (Burstall 1984). Recent comparative measurements have found a larger oak near Motueka in the Top of the South register.notabletrees.org.nz/tree/view/694 .  There are several older records on the database that may be strong contenders now and we are certain other large trees exist.  If you have a local tree you wish to add to the database we’d be happy to see it.  If you are located in Hastings we would be keen to have an update on the Frimley Park tree that was last measured in 1983. register.notabletrees.org.nz/tree/view/213

New Listings

A standout new listing is the ‘Grange’ Norfolk Island pine (NIp) located near Warkworth (pictured, photo credit: Lyn Wade).   This tree was missed from early tree surveys and first measured by S. W. Burstall just after he completed his unpublished forest mensuration reports and his subsequent book, ‘Great Trees of New Zealand’.   The tree has the largest girth of any NIp in the world and, whilst not the tallest, is the current world champion with 526 points.

New Features

Map Feature – this feature is not exactly new but it transpires that the majority of people have not found it yet!  We have made it easier to locate. Try searching Norfolk Island pines, select ‘All Trees’ and search.   At the top right of the column of search results is ‘Click to view all results on a map’.  This will take you a Google map with a marker for each tree shown in a distribution view.  You can click to view any tree.  Searching and viewing all our records with this feature makes for a very interesting picture!

Tree Dimension Format – here is a really functional format.  This allows users to compare search results with ease without having to jump from one record to another.  Try searching blue gum, select all records and click search.  At the top left of the column of search results is ‘View Results by Tree Dimension’.  You will now see the data is showing in height, girth, diameter and spread format.   Each column header can be clicked to ‘sort by’ largest to smallest.  Give it a go – its great.

Recent Updates and New Trees – we appreciate finding new trees was easy, as these were always added to the end of the register.  Locating newly updated trees was a bit more of a challenge, so we have created a ‘Recent Changes’ report that users can quickly scan to see the most recent changes to the database.   This can be found on the right-hand side of the Home view page register.notabletrees.org.nz/

Ten Year Report – this feature is also located on the Home page view.  This report allows a user to quickly locate any trees in their area that require a measurement or verification update.   Simply click the link and scroll to your region then, grab your notebook and measuring gear - and off you go!

Thank you to those that have sent in updates and new tree records.  For those of you who would like to get in on the action to update tree records or register as a tree recorder simply go to our website and follow the instructions.

May 2010 Newsletter - 21st May 2010

Angophora costata - Hobsonville. Image credit: Brad Cadwallader Dear Notable Tree Enthusiasts,

Our last newsletter stimulated some considerable discussions! Many people seem to have encountered larger radiata pines that our New Plymouth Tree 714 and quite a few of you seem have cut larger ones down. A 'report' of 80m trees being cut down near the Bridge-To-Nowhere on the Whanganui River was most interesting! Alas, there appears to be no evidence or formal record. Several trees claimed to be larger in diameter were found to be multiple stemmed trees and so do not qualify. Even the Awaroa macrocarpa 686 was challenged, but we are confident that it is a single stem.

A Note About Champion Trees

Only single stemmed trees are considered for champion tree status and will have scores automatically calculated on the database. In other words, only trees that contain a single pith within the girth measurement will qualify. Champion tree scores are not calculated for trees with multiple or fused stems although we still recognise the historical and cultural significance of these trees on the database.

An Update - A World Class Angophora!

Our pick of newly updated records is the Angophora costata at Hobsonville (pictured, image credit: Brad Cadwallader). This tree has long been considered as our second largest tree of this species in New Zealand. It has been recently found to be the largest in the country and may well be the largest in the world. This extraordinary tree is well worth a visit if you are ever in the Auckland area. register.notabletrees.org.nz/tree/view/334

New Listings

Of note amongst our new tree listings are 10 dawn redwood records from around the country. Some of the tallest and largest can be seen by using the genus/species search or our NEW FEATURE, the common name search. Try searching ‘dawn redwood’, ‘water fir’ or ‘shui-shan’. If you then click on the 'Score' at the top of the column you are able to further sort your selected data to find the current National Champion and top 5 specimens of this species identified in a recent national survey undertaken by Brad Cadwallader. Some of the other trees listed, whilst not large, are significant because they are some of the first trees on record to be cultivated in New Zealand.

Several Norfolk Island pine trees have been added to our records. These Northland trees were amongst the first of the species introduced into New Zealand in 1836. The Waitangi tree is quite outstanding and despite the presence of multiple tops, so too are the Wahapu Reserve and Scandrett Regional Park trees.

Thank you to those that have sent in updates and new tree records. For those of you who would like to get in on the action to update tree records or register as a tree recorder simply go to our website and follow the instructions.

Christmas Greetings from the New Zealand Notable Trees Trust (NZNTT)

The NZNTT Database is Open
For those of you that did not attend the New Zealand Arboricultural Association conference in Blenheim last month, the Trustees wish to inform you that the NZNTT database is now open for viewing.

The database is accessible through the NZNTT website at www.notabletrees.org.nz
Here you will find a link to The New Zealand Tree Register on the Tree Register page or you can follow this link register.notabletrees.org.nz/tree/search . You do not need to log in to view the tree files.

The information contained on the database is searchable in various formats i.e. genus, city, region etc. After you have made your initial search, further sorting can be achieved by clicking on the column headers i.e champion tree score. To open a tree file simply click on 'view'.

Much of the existing tree data requires updating. Records shown as unverified requires confirmation the tree still exists or needs to be re-measured. If one of these trees is in your area you can assist the Trust by sending an update via the information submission form which is located at the top of each online tree record.

Register as a Tree Recorder register.notabletrees.org.nz/user/register
If you would like to submit new trees to the NZNTT, click on the link above to open an account. You will be sent a message when your account has been enabled. A guide to measuring, recording additional information and the submission of new trees online are contained on the NZNTT website.
