Significance of the sectorPlantation area in Parana´
695.790 ha yellow pine
157.920 eucalyptus totaling 853.710 ha
Target 2 millions ha in 5 years
Exports - 5% of the total of Paraná (just behind car industry ), totalling US$ 155 million/year
6,6 million m3 logs - 83% from planted forests - 3 million m3 sawn wood
3.700 companies, 75,6% of which saw mills 24,5% processing 38.000 jobs.
Pulp and paper 1.039 .000 ton/year (6,5%) of national production

Sylviculture
Yellow Pine (Pinus taeda, Pinus elliottii): Lots of knots and
relatively low mechanical properties
And
Eucalyptus: few knots but high dimensional instability
Species developed essentially for pulp and paper
Historical Yield increment
Eucalyptus 14 in the 70’s up to 38 m3/ha/year after 90’s
Pine 18 in the 70’s up to 33 m3/ha/year after 90’s
Development of native species :
Açoita-cavalo , ANGICO-VERMELHO (Parapiptadenia rigida
Bent. Bren.), ,Cabreúva , CANAFÍSTULA (Peltophorum dubium
(Sprengel) Taubert) ,Canjerana, Caroba, Grápia, Guajuvira, Ipê-
amarelo, Ipê-roxo ,Louro-pardo,Marmeleiro, Pau-marfim, Peroba

Drying
Humid wood :
Increases transportation cost
Cause dimensional instability
Lower mechanical properties
Low cost kilns
Market demand for dry lumber
Drying operational control needs technical training

Residue management
Eucalyptus Bark:
Too acid to leave on the soil
Too harming to be used as chicken beds
Too low energy potential to burn
