Giants Grove – Data for the Future
The worlds first forest management school was founded in the University of Giessen, the Holy Roman Empire, in 1778. For the majority of those almost 250 years the basic forest management tools were the humble pencil & paper. Data collected in the field was meticulously recorded with such detail and precision that the finished result often looked more like art than a working file to my modern eyes. One of the finest, oldest, and most beautiful of these documents is the Birr Castle Demesne Tree Inventory which is kept safe in the Archives of Birr Castle.
Considering my handwriting, things have luckily changed a lot since then, particularly in recent years. Today the basic tool of forest mapping is the Geographic Information System. Put (very) simply, G.I.S. is a type of database containing geographic data (boundaries, plots, locations, etc.) combined with computer software to analyse and manage that data. Basically, the map and the data are now one document, and although it is not as beautifully presented it is far more efficient, easier to create, simpler to use, and a lot more useful than the paper documents of old.
So, considering the history of such detailed forest mapping in the past at Birr Castle, and the long 1200-year future ahead of the Redwoods at the Giants Grove, we recently decided to completely overhaul and update our GIS using the most modern, advanced, Global Positioning System (GPS) available. Now every Giant’s position in the largest Redwood Forest outside of the United States is accurate to within 2cm. The decision was made as we believed it was essential to provide a strong foundation for all the future data yet to be collected from the Grove.
Right now, individual trees can be assessed and highlighted for management inputs such as fertiliser and vegetation control, or problems can be recorded, measured, and instantly shared from the field to anyone involved. However, the real advantage will be how the current data will be used as a basis in future experiments. For example, the soil will be analysed at regular intervals to see how the Redwoods impact carbon sequestration, microbes, and nutrition, over time. Or the growth rates will be examined to see how the Redwoods respond to the various site types and nurse species influencing them.
Perhaps the most important data will come from studying the effects of climate change, particularly as this is a very real threat to the Redwoods in their native sites. Every little detail of this project will be studied, and the more accurate our information is today, the more accurate and effective our data will be tomorrow. Hopefully it can make a difference.
Of course there’s always a down-side, and unfortunately now anyone visiting their tree at Giants Grove will find that it’s coordinates have changed as the old system was only accurate to within 4 meters on a cloudy day. But don’t worry, the new system will allow you to enter the coordinates into Google Earth, and you can be directed straight to within 2cm of your tree.
Young Redwood forests are very rare, not many people have seen one, so come visit Giants Grove.
The Giants Grove Project is an Partnership between Birr Castle Estate and Crann – Trees for Ireland , it is managed by Ecoplan Forestry. It is the largest Sequoia / Redwood forest outside of the United States.

This is an inspirational and very timely voluntary initiative. As the redwood trees in California are being damaged and devastated by drought and wildlifes, Giants Grove in Birr is seeking to put down sturdy roots. People all over the world are now sponsoring these redwoods to help protect our planet’s future.

Hi Clara, thanks for your comment. Yes, protecting the Redwood species is one of our top priorities at Giants Grove, and in fact representatives from Save the Redwoods League recently visited us while the Redwoods were being devastated by wildfires in their native California

Fascinating, and we are lucky to have archives going back many years in the Estate Office and the castle which may help in the future to track all our trees. These include trees grown from seed from China over the last century as well as our own old Redwoods. Alison Rosse

Hi Sean, will we be notified of the new GPS co ordinates by letter ?
Sean McGinnisPosted at 11:52h, 24 July
We didn’t intend to write letters about the changes to all sponsors, as the changes were quite small and it would take time and expense, but it is something we could look into for you
