Kort præsentation

Jeg arbejder med vand-, kvælstof- og kulstof-kredsløb i skove og naturområder med henblik på at kvantificere, hvordan ændringer i arealanvendelse (fx skovrejsning og træartssammensætning), luftforurening (især N-deposition), klima, samt skovdrift og naturpleje påvirker stofstrømme, processer og puljer i økosystemer (fx mængden af kulstof og kvælstof, der er ophobet i jorden). 

Jeg har især fokuseret på kvælstofkredsløb og nitratudvaskning, dels for at undersøge miljøeffekterne af øget luftforurening med kvælstof, dels for at estimere naturens tålegrænser for denne forurening. Aktuelt undersøger jeg i hvilket omfang skov og natur er påvirket (eutrofieret) af øget kvælstofnedfald (især pga. ammoniakfordampning). Jeg har arbejdet med skovkanter ud mod åbent land, hvor kvælstofnedfaldet er særligt forøget. Depositionsgradienter i skovkanter er ’naturlige’ eksperimenter, der giver særlige muligheder for at studere langsigtede ændringer i stofkredsløbene fra kvælstofdeposition.

Jeg arbejder med miljøgoder fra skovrejsning på gammel landbrugsjord. Jeg har samlet en række dataserier om faldet i nitratudvaskning efter landbrugsdriftens ophør både på kort og på lang sigt i disse nye næringsrige skove.

Et andet vigtigt langsigtet aspekt ved skovrejsning er kulstofbinding. Jeg har arbejder med tidsseriestudier med henblik på at klarlægge den langsigtede opbygning af jordens organiske stof efter skovrejsning i f.t. træarter og jordbundstype. Jeg undersøger interaktionen mellem kvælstof og kulstof i det organiske stof og spørgsmålet om hvorvidt øget kvælstofnedfald øger kulstofbindingen i jorden. Desuden deltager jeg i feltundersøgelser af stabiliteten af jordens organiske stof ’under’ et varmere klima.

Jeg har ledet forskellige forskningsprojekter om vandkredsløb i skov med henblik på at kvantificere fordampning fra nåleskov og løvskov set i forhold til åbent land. Viden om skovenes evne til at forsinke og tilbageholde vand så vel som træarternes temmelig forskellige fordampningsegenskaber kan i fremtiden anvendes til at regulere vandstrømme (og måske oversvømmelser) på landskabsniveau.

Min forskning er baseret på felteksperimenter (klimamanipulationer, N-tilførsel, træartsforsøg og skovbehandlingsforsøg)og langsigtet overvågning i skov og natur. Derfor har jeg også forsket i forskellige overvågningsmetoder (feltudstyr og design) og har stor erfaring med praktiske løsninger og effektiv udformning af feltforsøg.

CV

Professor, Forest & Landscape Denmark, University of Copenhagen, Faculty of Life Science. Born October 4, 1958; Married, 3 children. Education 1985: Engineer (academic), specialisation Ecology and Environmental Chemistry, the Technical University of Denmark (DTU). 1989: Ph.D. in Environmental Sciences, DTU. 'Air Pollution with Nitrogen Compounds: Effects in Coniferous Forest' (in Danish), 292 pp. Employments 1989-1992: Assistant professor, Laboratory of Environmental Sciences and Ecology, DTU. 1993-2006: Senior scientist, Dept of Applied Ecology, Danish Forest and Landscape Research Institute (DFLRI). 2006: Professor, Dept of Forest and Landscape Ecology, Forest & Landscape Denmark (FLD) University of Copenhagen, Faculty of Life Science Professional career After the PhD I was strongly involved in teaching and development of a new education in environmental science at DTU. My research focused on 'critical loads for nitrogen' and resulted in a concept paper still in use in European air pollution management. From 1993 as senior scientist at DFLRI, I acted as project leader on soft money contracts. Had a 7 month sabbatical at the Ecosystem Center, Marine Biological Laboratory, Woods Hole USA in 1995/96. My main achievements as senior scientist was 1) a synthesis paper on ecosystem responses to N addition in forest which one of the authoritative papers in the field; 2) the compilation and analysis of observational data on N cycling leading to a number of well cited papers including the documentation of the control of soil C on the forest N cycle; 3) the use of 15N fate to track N and C retention; 4) a major synthesis on nitrate leaching from forests; 5) the development of an experimental concept for simulating ecosystem warming by use of automatic curtains keeping heat in the system at night, now used in 10+ experiments in Europe; and 6) a cooperation with S. China Inst. of Botany on N experiments in tropical forests, 15 papers. My skills in research innovation may be illustrated by my involvement in the development of 5 successful proposals (one as coordinator) during the EU FP5 programme period. Now Professor at FLD with a moderate teaching responsibility and currently supervisor for 2 PhDs. Resent works are on environmental services and C sequestration in soils. Key research topics: Biogeochemical cycling of N, C and water with main emphasis on N cycling in forests where I have become one of the leading scientists in Europe. Controls on C sequestration in forest soils (N, tree species, forest age). Afforestation impacts on soil and water. Forest monitoring methods. Long-term manipulation experiments. Climate change and mitigation. Environmental services from forests. Impact I have co-authored 80 refereed papers (69 in ISI journals) which have generated >2900 citations (Web of Science). The two best papers each have ≈300 citations. h-index: 31 . Services to academia, memberships. Subject editor of Biogeochemistry, Springer Verlag 2003-2008.
