O Contexto

The Context

400 millions ha of tropical production forests to be managed

for commercial harvesting

Managed (= Logged + silviculture) and disturbed tropical

forests cover larger areas than primary ones

Managed and disturbed tropical forests are the forests of the

present and of the future

Most of our knowledge on tropical forests is from studies

carried out in primary forests

No continental, nor regional network dedicated to managed

forests like for primary forests (Rainfor, CTFS)

Exploração Seletiva = Degradação ? Depende…

Selective Logging = Degradation ? It depends…

RIL = No ? Conventional = YES

• Counting on forest natural regeneration/Conta com a regeneração natural

• Focused on timber exclusively/ Focalizada na produção de madeira

• But sometines/often: No planning and high damage (50% of the stand)/ usualmente

sem planejemento e com danos muito altos

• Based on a very simple rule: the minimum diameter cutting limit/ Baseada numa regra

muito simples : o diametro minimo de corte

Exploração : Além da Madeira

Logging : Beyond Just Timber

• Logged Forests still harbor high Carbon stocks and high

biodiversity…

• The main limitation stands in the recovery rate of timber

volume

• Logged forests remain forest (Gibson et al. 2011)

• What are the general responses of tropical

forests to logging ? Quais são as respostas das

florestas tropicais a exploração madeireira ?

• How do those responses vary across regions

and continents ? Como estas respostas variam

nas regiões e entre os continentes ?

• What are the trade-offs between economic

and environmental values ? Quais são os

compromissos entre os beneficios economicos e

os valores ambientais?

• What is the conservation value of managed

forests ? Qual é o valor de conservação das

florestas manejadas ?

Uma Rede Pan Tropical

A Pan Tropical Network

• 24 experimental sites, 490 Plots (921 ha)

• Annual budget of ~150.000 US Dollars (Main donor: CGIAR)

TmFO na Amazonia

TmFO in the Amazon

• 11 Experimental sites

• 5 countries

• 245 Plots (672 ha)

• 35 Control plots (164 ha, 25 %)

• Mean period of monitoring 15

years

Compartilhamento dos Dados

Data Sharing and Flow

• Raw data remain with site

leaders and institutions

• Common protocol of data

analysis

• Metadata are shared among site

leaders within the same region

• Participatory Research

favouring discussion and

knowledge sharing among

scientists

• Preserve data source and

ownership
