ACKNOVLEDGEMENTS

I am grateful to directors, staff and employees of the PVN for their cooperation and support, especially for maintaining the study area and building rabbit traps. The game wardens helped with collecting much of the data on rabbit body weights. Dr.S.Broekhuizen and F.Maaskamp (Research Institute for Nature Management) showed much interest during the study and provided instruction on some techniques. F.J.S.V.Korner and the men at the workshop of the Zoological Laboratory made the tags and adapted the equipment to field circumstances. Drs.Mimi Roetering helped me in finding the literature. M.L.Brittijn, J.M.J.Herzberg and H.Heijn drew the figures. J.Simons and Fieneke Speksnijder set them up. Rina van der Niet en Ceciel Sassen typed parts of the manuscript. Dr.H.E.van de Veen (Free University,Amsterdam) and prof.dr.R.A.Prins (University of Groningen) inspired the study on the quality of food for wild-living animals. I

thank Evelien Zantman for advice on the chemical analysis, which was carried out by Irene Ettinger, H.Halm and the author. Dr.J.F.V.Nuboer (University of Utrecht) stimulated the observations on the activity of wild rabbits. Dr.N.Straw was so kind as to correct the english of the first and last chapter.

Furthermore, the following helped me in gathering the data, in good and bad weather and at the most unsociable times of the day and night: R.Akkermans, R.Bakker, Th.Bakker, J.Damm, V.Denneman, Dory van Dierendonk, G.Dinsbach, F.Distelbrink, Erica Drees, Corrie Elders, Dorien Farjon, Judith van Genderen, Gerda Geut, Heleen Goddijn, A.Guldemond, C.ten Haaf, H.J.Immink, A.James, Els Jans, Elsje Jansen, Marielle Jansen, N.Jonker, Yvonne van Manen, J.van Mourik, J.L.Mulder, M.van Nierop, Sari van Noorden, Els Nijssen, J.Roggeveen, Marjon Rutz, Hies Schollard, Maud Scholten, Margriet Stapel, A.Steeman, D.Tanger, Henny van Veen, Sj.de Vaard, V.de Yart, H.van de Vater, A.Veeda.
