1 EUROPEAN FOREST SECTOR OUTLOOK STUDY II Comments, proposals Prof. Andrius Kuliešis Lithuanian State Forest Survey Service Kaunas, Pramonės av. 11A 1

2 FOREST SECTOR Wood growing Wood processing Forestry Forest industry Efficiency Competitiveness 2

3 INDICATORS OF WOOD GROWING EFFICIENCY Natural losses of wood growing Volume of mature stands 3

4 BALANCE OF GROSS ANNUAL INCREMENT Lithuania NFI % of all wood increment contain mortality 29% intermediate fellings 32% final fellings 1% reserve for final fellings Z M = Δ 1 + Δ 2 + M K + M 15,9 = 2, + 5,1 + 4,6 + 3,4 1 =

5 WOOD INCREMENT BALANCE IN COMMERCIAL FORESTS DEPENDING ON FOREST TYPE AND AGE Lithuania NFI Annual increment, m 3 /ha Pine Spruce Age, years Birch Annual increment, m 3 /ha Aspen Black alder 12 White alder Age, years Δm Mk Mok Mo - increment accumulation - intermediate fellings - dead wood fellings - forest growth losses 5

7 NATURAL LOSSES account for.7 per cent of gross annual increment in Europe, 26.7 per cent in the CIS and 2.2 per cent in the USA Main report TBFRA-2, 153, p.p. Europe -.7 Finland - 2 Austria - 5 Sweden - 7 Norway - 7 France - 9 Germany - 9 Switzerland - 1 Lithuania - 2 Latvia - 2 Estonia - 24 Russia - 27 Belorussia

8 VOLUME OF MATURE STANDS Integrally indicates efficiency of forestry - level of yield - sustainability of forest stands Discovers resources of mature wood

9 Reserve for future use CONVERSION FACTORS Scheme of timber flow Export Import Wood growing Felled G.S.V. Wood processing Other users Energy G.A.I. Not used in protective forests Used Used for for fuelwood fuelwood Natural Natural losses, biodiversity biodiversity Mortality Felling Felling residuals residuals Fire Fire wood wood Products Residuals Residuals

10 EFFICIENCY OF LOGGING Can be characterized by the ratio of round wood volume, taken from forest, and growing stock volume (R) or amount of round wood in m 3 (M), logged from 1 m 3 growing stock volume 1

11 STRUCTURE OF FELLED WOOD 1 m 3 growing stock volume: Stumps 2 Bark 12 Tops, cuts 1 Allowances 2 Roundwood 3 11

12 OUTPUT OF ROUND WOOD FROM GROWING STOCK VOLUME (according Annex 1: conversion factors...) Number of countries Efficiency of logging R M, m 3 per and < 91 and > and > 7 and < Losses per 1 m 3 G.S.V and >

13 VOLUME OF ROUNDWOOD REQUIRED TO PRODUCE ONE CUBIC METER OF SAWNWOOD depends on roundwood size sawmilling technology for 39 countries (Annex 1: conversion factors) varies from 1.42 till 3.42 Finland Sweden Lithuania

14 DATA ON ROUNDWOOD SUPPLY AND USE IN LITHUANIA 27 BY DIFFERENT SOURCES Type of sortiment, industry JFSQ EFSOS-II Wood supply Industrial roundwood Fuelwood Bark 41* 91 Wood use Sawmill industry 276** 21 *JWEE ** actual 14
