Systematic thinning, removing

Due to problems with stem form and excessive branching, by

1939 Andrade advocated planting 2x2 m and frequent application of light thinnings

- 1960: First forestry graduate course in Forestry engineering established inViçosa, Minas Gerais. Later moved to Curitiba, Paraná.

- 1966: Law of tax incentives (Lei no5.106-02/09/66)

Allowed the use of up to 50% of owed taxes in reforestation programs.

Consolidation of Eucalyptus in Brazil

Requirements:- Must own or rend the land- Minimum of 10000 planted trees per year- Productive or protection forests

- 1988: End of tax incentives, beginning of the modern phase of silviculture,characterized by the search for efficiency through the control of productioncosts and increasing yields.

What causes mortality of the stumps?

- Stump should be kept free of harvest residues

- Avoid damaging the stumps

- Harvest type has influence

Does a coppice stand produce as well as high forests stand?

Old technology:

Residue burning

Excessive stumps/sprout

Small application of fertilizers

New technology:

Minimum cultivation of the soil
