I believe that it's 1999. The latest year directly referenced in it is 1998.
The last page says "On the other hand, faculty and researchers at the Michigan
Technological University (MTU) School of Forestry and Wood Products
have found that the Project ELF’s antenna grid makes the trees grow faster.
MTU foresters have been studying the effects ever since the system became
operational ten years ago."
1989 is when the Project ELF system started operating, so "ten years ago" indicates 1999 for the document.
- MandieD 3y agoThe PDF itself was created in 2005 and the file date in the parent directory the same date as the PDF, so that's the absolute latest date, but I'd also guess 1999 for the original paper. Not sticking a date on it without a bit more certainty, though.
- dang 3y agoThanks to you both! Let's be conservative and go with 2005.
