I can't answer all your questions. However, an article which ran in today's
The Oregonian (8/26/98, B7) might be helpful:
Potlatch Corp. Hopeful about harvesting hybrid poplars
BOARDMAN - The Potlatch Corp. hopes to harvest 22,000 acres of hybrid poplar
trees near Boardman for pulp by the year 2000 if the coyotes don't get them
The trees are kept alive by a drip irrigation system, which delivers water
through rubber hoses.
Coyotes, just like Rover at home, enjoy chewing on them, said Greg Uhlorn,
project manager at the Potlatch hybrid poplar probram.
The hoses provide drips of water mixed with fertilizers at the slow rate of
three-quarters of a gallon per hour.
Each poplar requires 12 to 15 gallons of water annually in the early years;
that figure stretches to 35 to 40 gallons as the trees grow.
Potlatch's poplars reach 65 feet in their fourth growing season.
Portland began its poplar project in 1994 with 800 acres of trees. By 1999
Potlatch hopes to have developed all of its 22,000 acres.
