4 Use of forests

5 Timber production Tierra del Fuego (2006/07) Sawlogs: 110,000 m 3 Area logged: 1,200 ha Forest management issues Tasmania (native forest average 2001/06) Sawlogs: 400,000 m 3 /yr Pulpwood: 4,400,000 tonnes/yr Specialty timbers: 20,000 m 3 /yr Area logged: 33,000 ha/yr (25,000 ha/yr regenerated)

6 La construcción de represas en terrenos de topografía relativamente plana causa el anegamiento de grandes superficies, en su mayoría, cañadones boscosos. El efecto de esta inundación es la muerte por asfixia de los arboles y otras plantas. Superficie boscosa afectada por la actividad de castores: Superficie relevada: ha Superficie afectada: 977 ha Porcentaje de afectacion: 6.1 %

7 Forest planning and regulation

8 Tierra del Fuego Management Plans required under National or Provincial laws for public and private land Prepared by foresters Detailed mensuration data, which determines silvicultural system Environmental constraints strongly linked to physical site attributes (watercourses, drainage, slope) Checked and approved by government regulation agency Chilean sector: CONAF (national) Argentinean sector: Secretariat of Sustainable Development and Environment (provincial) Fotointerpretación Bosque de lenga Bosque Floreado Producción Protección Preservación Classification by condition and type Bosques de Ñire Bosques de Lenga Puros Bosques Capados = Degradados Sistema de Información Geográfica Subsecretaría de Recursos Naturales

9 Classification by topography Availability Total forest: 712,000 ha Commercial forest: 201,000 ha Abrupto Isletas Nothofagus antarctica Commercial forest Non-commercial forest Plano-Ondulado Nothofagus pumilio Ñire Mixed Forests Sistema de Información Geográfica Subsecretaría de Recursos Naturales Forest harvested and Commercial public forest available for future harvesting

12 Use and tenure of Tasmania s forests PRIVATE FOREST - NATIVE PRIVATE FOREST - PLANTATION PUBLIC FOREST - PLANTATION PUBLIC FOREST - NATIVE PUBLIC FOREST - RESERVED RESERVED FOREST - PRIVATE How will the future evolve? Reduction in timber availability in native forests: Natural events Community attitudes Increased protection (reserves and off-reserve) Unsustainable logging in the past Recognition of other forest uses Alternative sources of timber products Stricter regulations Research and monitoring: Important to do it, apply it and share it Important to support it Forest connections: Tasmania, Tierra del Fuego and beyond: No man is an island and no island is an island Thankyou for your interest and acknowledgements to: Pablo Peri Germán Duarte Pedro de Valdivia and family Staff and Board of the Forest Practices Authority The Gottstein Trust Forest Practices Authority, Tasmania Facultad de Ciencias Forestales Universidad de Chile Intermission
