  30. 30. Sovon Vogelonderzoek Nederland • Keep counters satisfied and recruit new • A new MUS course • More in detail look at the environment • Start of a year round garden count http://www.tuintelling.nl/ • A course for professionals about spatial development, how to keep the birds in your building • A public website benchmark Future
  31. 31. Sovon Vogelonderzoek Nederland Future
  32. 32. Sovon Vogelonderzoek Nederland • MUS is a good monitoring program for urban species • Birders like MUS • After 8 years we have trends of about 75 species • Recent the House Sparrow is stable on a low level • Does it better in the higher part (sand) of NL • The highest numbers in the after WW2 districts • Also the highest density is found in the younger (1-2x higher whole NL) cities and districts and give hope for the future • But we have to look more in detail of buildings and habitat • And keep the birders enthusiast. Abstract
  33. 33. Sovon Vogelonderzoek Nederland • to the dedicated MUS-counters • Birdlife International – the Netherlands, NEM and CBS • photographers Harvey van Diek and myself • my colleagues Erik van Winden en Henk Sierdsema • for invite and listen to me! Thanks to
