1 Country report Iceland Arnór Snorrason Icelandic Forest Research Icelandic Forest Service

2 Overview About the Icelandic Forest Inventory (IFI) Development and new projects since the Kauna meeting 2013: 1. New map of the natural birch woodland 2. Changes in greenhouse gas (GHG) estimate 3. Using NFI data in CO 2 sequestration prognosis 4. Using NFI data in regional wood production prognosis 5. Estimating biomass of tree species for the European Joint Research Center.

3 Icelandic Forest Inventory (IFI) A project at the Icelandic Forest Research (IFR) Mógilsá IFR a one of three divisions of the Icelandic State Forest Service IFI Personnel: Arnór Snorrason, Björn Traustason and Bjarki Þór Kjartansson other IFR staff participate on various subprojects of IFI

4 Ongoing and finished main projects First NFI cycle (2005-9): The country wide sample plot inventory in both cultivated forest and natural birch woodland finished in year Second NFI cycle ( ): Re-measurement of cultivated forest. Remapping of natural birch woodland ( ). Third cycle of cultivated forest and the second cycle of natural birch woodland started this summer 2015 and will last to 2019.

5 No. of plots in NBW : 210 No. of plots in CF : 810

7 1.New map of the natural birch woodland The are of natural birch woodland has increased: estimated 1380 km 2 in 1989 estimated 1510 km 2 in 2014 increase of 130 km 2 increase of the natural birch woodland is confirmed for the first time an inversion from the 1100 years deforestation

9 Changes in greenhouse gas (GHG) estimate Iceland is still participating in the Kyoto protocol Iceland as Norway joined the EU-bubble Bilateral agreement to EU did allow Iceland to account C- sequestration from afforestation and revegetation as major mitigating effort. A reporting in a new commitment period started last winter ( ) with great increase in data delivery and working load: New reporting rules and guidlines: 2013 Revised Supplementary Methods and Good Practice Guidance Arising from the Kyoto Protocol Forest Management is mandatory Reference level for both ARD and FM has to be re-estimated More issues to take into account: Carbon Equivalent Forest Conversion (CEFC) Natural Disturbance Harvest Wood Product (mandatory reporting)

10 Gg CO2 Using NFI data in CO2 sequestration prognosis Net sequestration of afforestation since 1990 in CO2 -equivalents S1 Uchanged afforestation rate 1092 ha annually S2: Afforestation doubled S4: Afforestation quadrupled S1: CO2 in roundwood S2: CO2 in roundwood S4: CO2 in roundwood

13 Using NFI data in regional wood production prognosis 63 NFI plots of 145 where used as a source data to estimate area, current and future wood stock in the Fljótsdalshérað region (see Heidarsson).
