Editor's note
A planting tube, a traffic camera, a satellite.
Three instruments this week, and all three are being asked to prove something rather than to discover it. The GPS on the planting tube tells nobody anything new about forestry. It exists because a contract says a number of seedlings went into particular places, and until now nobody could show that they had. The Maryland paper is an adjudication: two measurement systems disagreed about whether old forests are still growing, and someone had to say which one to believe.
Proof is a different engineering problem from discovery. It rewards dull reliability, five to six working days per charge, agreement with an accelerometer to a hundredth of a hertz. It punishes the clever demo.
That is where the money goes this week too, into the instruments and into a market for what they find. The open question is who ends up paying for proof: the buyer, the regulator, or the insurer.

A GPS unit on the planting tube logs every seedling
We covered TerraLab's STA system from New Zealand in #026, one of three routes to seedling-level data. Sweden has its own now, built by Daniel Nilsson at Umeå University and Jonas Bohlin at SLU rather than by a company. It runs five to six working days per charge and turns a day of planting into a work report. The point is contract verification: proving the agreed seedlings went into the agreed places. Still a prototype.
DRI reads tree sway from video to within 0.03 hertz
Joe Ammatelli's team models a tree as a cantilever beam, so sway frequency tracks mass and stiffness, and a drier tree sways slower. Video lands within 0.03 hertz of accelerometers, and Caltrans and Nevada DOT cameras already point at trees all day. The catch is in their own paper: diurnal water change is still too subtle to read, with drought results due in 2027. Flagged by Johan Ekenstedt of Arboreal.
A Maryland team finds mature forests growing off the satellite record
Optical sensors read a forest from above, and once a canopy closes and passes roughly 16 metres there is little left in the picture to change. Wood added underneath does not show up. Ground crews measuring trees across the United States record 102 million tonnes of carbon a year of growth in older stands where the satellite record sits flat. Lidar, which measures structure rather than colour, sides with the crews.
Europe's new growth fund picks a radar satellite company first
The European Commission built a fund to stop large European companies raising their late-stage money abroad, handed EQT the job of running it, and pointed it at 5 billion euros. Its first cheque goes into a round ICEYE closed back in June. The Finnish company flies radar satellites that see through cloud and smoke, which is what puts it in a forestry newsletter: fire monitoring, extended to Canada in July, and the deforestation service from #041.
The US Forest Service puts 105.5 million dollars into wood markets
That is 177 projects across 44 states and the District of Columbia: 31 million for wood innovation, 17 million for community wood, 57 million for processing infrastructure. Thinning and restoration work produces small logs and residue that nobody wants to buy, so the material stays in the forest as fire fuel. Chief Tom Schultz calls that missing market the greatest threat facing forest landowners.
