Abstract Although the regulations are imperfectly enforced, logging firms in the Brazilian Amazon are subject to
forest management regulations intended to reduce environmental damage and protect future forest productivity.
Additionally, voluntary best practices firms adopt to achieve environmental performance that
exceed regulatory requirements are largely limited to reduced impact logging (RIL) systems that reduce
harvest damage relative to conventional logging systems used by a large majority of firms in the region.
Existing regulations combined with best practices may not be adequate to ensure sustained yields. This
inadequacy is an important issue as Brazil implements an ambitious program of forest concessions on
public lands. We analyze the profitability and environmental outcomes of best logging practices and
proposed sustainability requirements. We propose two operational definitions of sustainability (the first
focusing on sustaining stand-level timber volumes and the other focusing on sustaining species-level
volumes within the stand) based on sustaining timber inventories across cutting cycles rather than on
sustaining overall harvest yields. RIL is shown to be profitable for loggers and increase the timber available
for future harvests. While volume predicted to be available for the second and third harvests are
significantly lower than the available timber in the unlogged forest, the second and third harvests are
projected to be profitable and have the potential for sustainability despite high opportunity costs. However,
as harvesting is repeated into the future, results show the composition of the harvest shifts from
higher-value shade-tolerant and emergent species toward a greater reliance on longer-lived, lower-value
pioneer species. This shift may create pressure to expand the forest base under management in order to
continue to supply high-value species or increase the risk of timber trespass in conservation units and
areas under community or indigenous management.
