  1. Soil, Water, Vegetation (SFI - 3 08 04) prof. dr. Nico van Breemen Soil Formation and Ecopedology Group dr. Marcel Hoosbeek Soil Formation and Ecopedology Groupdr. Marcel Meinders Soil Formation and Ecopedology Group dr. Wim Braakhekke Nature Conservation and Plant Ecology Group drs. Dick van der Hoek Nature Conservation and Plant Ecology Group dr. Flip Witte Soil Physics, Agrohydrology and Groundwater Management Group SWV - Ch 01 and Ch 02

  2. Practical points • List of Participants: newcomers fill in list now • Syllabus: Price: € 14.00 (secretary SFI; pay exact please) • Time table: NB. rooms have been changed !see hand out • Web link: www.dow.wau.nl/natcons/NP/ • Click on Student info or Education and on Soil, Water, Vegetation to find: • Time table • Presentations of lectures on Ch. 1 – 3 (updated after each lecture) • Excel worksheet needed for tutorials in Ch 3.7 • Information on other chapters follows later SWV - Ch 01 and Ch 02

  3. Prerequisiteknowledge • Ecologie (NCP- 1 03 04) Hfdst Kringlopen + werkcollege 5 • Inleiding Bodem en Water (SFI - 1 08 04) (or : Inl. Bodem + Inl. Water) • Assumed knowledge: • Systems and Landscape Ecology A (NCP - 3 04 04) Ch 6 and 7 • Bodemkunde I • Related ecological courses: • ‘Vegetation Science and Systems Ecology’ and ‘Groeiplaatsanalyse’ • (analysis of vegetation and abiotic factors and their (cor)relation SWV - Ch 01 and Ch 02

  4. Aim of the course SWV • Understandthe processes causing the correlation vegetation - habitat • short term processes: plant physiology, organic matter and nutrient dynamics in the soil • long term processes: soil development; evolution • cyclic interactions of soil and vegetation; chains of causes and consequences: SWV - Ch 01 and Ch 02

  5. Cyclic soil  vegetation interactions Plants Soil conditions improvement or not (?) long term evolution ecosystem development Soil adapted plant species Soil development local habitat plant effects on organic matter and nutrient dynamics local flora Local vegetation composition SWV - Ch 01 and Ch 02

  6. Basic questions of the course SWV 1. How can plant species adapt to different soil conditions? (Ch 3) (acidity, toxic ions (Al), nutrients, water-oxygen) 2. How do soil conditions determine vegetation composition? (correlation; descriptive) 3. How does vegetation composition affect soil processes? (organic matter and nutrient dynamics  soil formation) 4. How do plant induced soil processes affect plant life and vegetation composition?(direction of succession; self-organisation of vegetation patterns) SWV - Ch 01 and Ch 02

  7. What is the result of cyclic soil - vegetation interactions? Does spontaneous ecosystem development automatically lead to ‘improved’ conditions and a ‘climax’ ecosystem? e.g. high biomass, efficient resource utilisation, high bio-diversity(?) Do plants improve the soil conditions to benefit plant growth?• Are plants ‘ecosystem engineers’? Are soils ‘biotic constructs’? How can this be reconciled with Darwinian evolution theory?• Why would pioneer species change the soil in favour of their successors? • Why wouldn’t plants control soil development in a more selfish manner?(1) improving conditions for themselves and (2) creating conditions unfavourable to others (3) and stop succession Answers ?? SWV - Ch 01 and Ch 02

  8. Work forms of the course Lectures (24 h) Self study (80 h; questions at the lectures) Tutorials (40 h; making exercises; working with computer models) Field excursions (8 h) Case studies (40 h; group work; written report + oral presentation) Written examination (English questions, Dutch or English answers) SWV - Ch 01 and Ch 02
