  1. 1/17 Diploma Thesis at Pasoh FR Density and vertical distribution of fine and medium roots in selected key tree species at Pasoh Forest Reserve 4th July 2005, Viktor Bruckman

  2. 2/17 About me • Viktor Bruckman, 24J • Education in Forestry since 1995 • Msc Student in Forest Sciences at UNI BOKU, Vienna; 8th of 10 Semesters • Working Experiences: • Several times working in a small forest enterprise (~250ha) 1995-2000 • Austrian Federal Forests (ÖBf AG): Land Measurement with Theodolite; since 2002 About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  3. 3/17 About me • Austrian Federal Forests (ÖBf AG): Developing documentation system for LM Workgroups (since 2004) • UNI Boku: Tutor at the Institute for Silviculture (since 2003) • Creating a CD for forest site indication; www.standortsanzeiger.de.vu (since 1997) About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  4. 4/17 Forestry in Austria • Forest coverage: 48% • Ownership structure as a thread • ÖBf AG is Austria´s largest forest enterprise: 15% of Austria´s forests, harvesting approx. 2million m³/year, 523.600 ha Forest • >80 % in mountain areas • Dominant tree species: Picea abies, Larix spp, Fagus sylvatica. • Yearly increase of biomass • Topography causes the need of fully mechanized harvesting About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  7. 7/17 Forestry in Austria About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  8. 8/17 Diploma Thesis at Pasoh - Why? • Specializing in Forest Ecology • Special Interest in Tropical Rain Forests • Relatives living in Pertang/Malaysia • Opportunity to study and get to know other ecosystems • Establishing contacts to Tropical Forest Experts and learn from them About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  9. 9/17 Main Objectives • Understanding the density and vertical root distribution (Roots < 1cm diameter) on three to four key tree species • To find out intra- and interspecific differences in vertical root distribution on different soil types or soil parameters, respectively • To find out more about the clay minerals at Pasoh in the upper soil layer up to 40cm depth. (Type, degree of crystallization, estimates on quantitative occurrence) About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  10. 10/17 General Information • Initial Idea from Prof. Peter Ashton • Specific difficulties: • Relatively few publications available • Lack of knowledge in root distribution in the soil of tropical tree species • Have not been conducted at Pasoh so far About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  11. 11/17 Sample tree species - Criteria • Relatively most abundant species • Possible species could be Diptero-carpaceae, Fabaceae, Euphorbiaceae • Morphology and DBH (sample design!) • There should be not too much understory About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  12. 12/17 Sample design (scheme after Weller, 1964&1971 in Böhm, 1976 and Monedero-Andrés, 2001, mod. ) About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  13. 13/17 Sampling Method: Hand Auger About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  14. 14/17 Root classification Root Diameter and appendant root class. (Modified after Böhm, 1976) About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  15. 15/17 Root recognition/separation • Color, structure, morphological specialties • Root juice (Color, smell, thickness) • Typical smells • Iron test ( terpenes can cause a change to blue color when touching the roots with iron e.g. a knife or a nail (no stainless steel) About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  16. 16/17 Preliminary work schedule About me > Forestry in Austria > Dip.-Thesis >> Sampling details >> schedule

  17. 17/17 Discussion of further questions • Root identification • Dryer • Costs / Fees • Tree identification • Data Sources • … www.rootresearch-pasoh.de.vu Thank You!
