In order to explain the trends of the different transects, we ask you to assess the habitat on a yearly basis in the area of about 200 m surrounding your transect. Habitat assessment implies only four questions.

1. What is the main habitat (200 m surrounding the transect) :

  • urban (including industrial, residential, transport and commercial areas)
  • Park (public or private park or open residential areas with lots of full grown trees)
  • Agricultural
  • Broad-leaved forest (less then 25% coniferous)
  • Coniferous forest (less then 25% broadleaves)
  • Mixed forest (mixture of broadleaves and coniferous trees)
  • Natural or semi-natural vegetation other than forest

2. An estimate of the extent by covered by the crowns of broad-leaved trees (200 m surrounding the transect) :

  • To estimate this, look at an aerial photograph of your transect for example via Google maps.
    • 0-25%
    • 26-50%
    • 51-75%
    • 76-100%

3. How much dead wood is available (200 m surrounding the transect) :

  • Estimating the amount of dead wood, including old trees (>1m in diameter), dead broad-leaved trees, broad-leaved tree stumps, and artificial logs (railway sleepers, log piles, …) of more than 40 cm in diameter
    • None or little (<1/ha)
    • Moderate (1-5/ha)
    • High (5-25/ha)
    • Very high (>25/ha)

4. Has the habitat (suitable dead wood) over the last five years been decreasing or increasing:

  • Habitat is decreasing
  • Habitat is rather stable
  • Habitat is increasing

If you find it difficult to fill in these questions, please contact the responsible at your country.
