Re: Gmelina arborea



Dr. Heaton,

We used 33 lb/ft3 at 45 % MC as a design basis for chipping gmelina for fuel
in Costa Rica (Turrialba region) some years ago. Average density was
0.42-0.45 with a maximum of 0.55

1.09m3 green = 1 m3 dry.

Typical plantation tree at 4 years was 30 cm dbh, 14 m 7.5%-10% bark.

Average log size was 25 cm diameter by 5 m

As a matter of historical interest Turrialba was the first location where DK
Ludwig started gmelina plantations in Latin America before embarking on the
massive plantations in Brazil (Jari Project) in the 1960s. I understand that
he tried to buy Costa Rica. Cost Rica was not for sale so Ludwig went to the
Amazon.

By the early 1970s my friends in Mexico had a preference for caribbean pine
over gmelina. As recently as 1990 Scott Paper (recently merged with Kimberly
Clark), Stone Container and others
were planting gmelina in Costa Rica. Yields were about 45 m3 dry per ha/year
or about 23 dry tonnes/ha/year.

Ston Forestal has about 14,500 ha of
gmelina still in Costa Rica. It looks like there only about 17,000 ha of
gmelina now in Brazil. (See the ITTO Newsletter
http://www.itto.or.jp/newsletter/v7n2/08industrial.html  and R. L. Flynn and
Associates, Latin America's Role in the International Woodfiber Markets, Nov
15, 1999, http://www.latco.org/flynn/China/sld018.htm )

Kind regards,

Tom Miles
