Selective logging is an extensive land-use practice in South America. Governments in the region have enacted policies to promote the establishment and maintenance of economically productive and sustainable forest industries. However, both biological

Canopy dynamics in unlogged and logged forest stands in the eastern Amazon

Autor: Mark Schulze, Johan C. Zweede

Publikováno v: Forest Ecology and Management. 236:56-64

Selective logging of tropical forests damages residual trees and creates canopy openings throughout the stand. In the Amazon, reduced-impact logging results in significantly less damage than conventional unplanned logging; yet either logging method l

Liberation: Acceptable production of tropical forest timber

Autor: Johan C. Zweede, Frank H. Wadsworth

Publikováno v: Forest Ecology and Management. 233:45-51

Reduced impact logging in an eastern Amazonian terra firme forest left more than half of the next crop trees growing at a rate corresponding to a rotation of more than a century to attain 60-cm dbh. Two years after the logging, in 20 ha of the logged

CANOPY DAMAGE AND RECOVERY AFTER SELECTIVE LOGGING IN AMAZONIA: FIELD AND SATELLITE STUDIES

Autor: Gregory P. Asner, Rodrigo Pereira, Johan C. Zweede, José Natalino Macedo Silva, Michael Keller

Publikováno v: Ecological Applications. 14:280-298

We combined a detailed field study of canopy gap fraction with spectral mixture analyses of Landsat 7 ETM1 satellite imagery to assess landscape and regional dynamics of canopy damage following selective logging in an eastern Amazon forest. Our field

Forest canopy damage and recovery in reduced-impact and conventional selective logging in eastern Para, Brazil

Autor: Gregory P. Asner, Michael Keller, Johan C. Zweede, Rodrigo Pereira

Publikováno v: Forest Ecology and Management. 168:77-89

We investigated ground and canopy damage and recovery following conventional logging and reduced-impact logging (RIL) of moist tropical forest in the eastern Amazon of Brazil. Paired conventional and RIL blocks were selectively logged with a harvest

Financial and ecological indicators of reduced impact logging performance in the eastern Amazon

Autor: Frederick Boltz, Geoffrey M. Blate, Rodrigo Pereira, Paulo Barreto, Roberto Bauch, Johan C. Zweede, Thomas P. Holmes

Publikováno v: Forest Ecology and Management. 163:93-110

Reduced impact logging (RIL) systems are currently being promoted in Brazil and other tropical countries in response to domestic and international concern over the ecological and economic sustainability of harvesting natural tropical forests. RIL sys

Remote sensing of selective logging in Amazonia

Autor: Gregory P. Asner, Rodrigo Pereira, Michael Keller, Johan C. Zweede

Publikováno v: Remote Sensing of Environment. 80:483-496

We combined a detailed field study of forest canopy damage with calibrated Landsat 7 Enhanced Thematic Mapper Plus (ETM+) reflectance data and texture analysis to assess the sensitivity of basic broadband optical remote sensing to selective logging i
