Andy is leading the field campaign, over 6 or 7 weeks, with Matheus, myself, Ewan and Joanna coming in and out over the duration. We've had huge help from ANPN Gabon, via Kath Jeffrey, Lee White, David Lehmann and others in organising permits, kit and logistics. Without them it's safe to say this wouldn't be happening. And they've also organised great local help, Leandre and Hector in particular, who are really helping to make the operation much more efficient.
Day 1 and we had this visitor following us on the road!
|No you can't have my lunch.|
|A 'typical' view of the second GEM plot.|
|Leandre carrying the Riegl out of the plot. A job for a younger man than me these days!|
|One of the giants we're here to scan, in the centre of our plot. Photos just don't do these trees justice - this one is 50+ m tall, with the enormous buttressed root system and a canopy that seems to be in the clouds.|
|A very small slice through the 1ha ZEB scan of the plot.|
I also scanned a single large tree in the corner of the plot, looping around it 3 times. The results from this are also very encouraging indeed. Here's a slice showing the tree with 2 slightly smaller (but still huge!) trees next to it. The white points are a second horizontal slice through the cloud, shown in plan view below.
|Scan of single large tree (well, 3 really).|
|A slice through the trunk of the large tree, at about 4m above the ground, with the other two smaller trees next to it, and the rest of the point cloud in gray around them. The larger tree diameter is around 1m.|
