TMAP Monitoring Handbook

Birds - Breeding birds

1 Introduction

The Joint Monitoring Program of Breeding Birds in the Wadden Sea started already in 1989 (Fleet 1989). The National Coordinator Group on the Joint Monitoring of Breeding Birds (JMBB) is responsible for the coordination, implementation, assessment and documentation of the monitoring program on breeding birds.

2 Objectives

The monitoring of breeding birds is carried out to detect and assess

  • Population sizes and distribution of breeding birds throughout the Wadden Sea as well as population trends;
  • Impact of climate changes on breeding bird populations;
  • Response of breeding birds to contaminants that affect fitness of breeding birds;
  • Impact of fisheries on breeding bird populations;
  • Impact of recreational activities on breeding bird populations;
  • Impact of agricultural changes (e.g. grazing) on salt marshes as natural breeding habitats of birds.

4 Definitions

All definitions and methodical descriptions are given in the guidelines "Monitoring of Breeding Birds in the Wadden Sea” (Hälterlein et al. 1995).

New added species of breeding birds relevant for the monitoring program are Little Egret (Egretta garzetta), Barnacle Goose (Branta leucopsis), Wigeon (Anas penelope) and Pintail (Anas acuta).

[revision of the guidelines "Monitoring of Breeding Birds in the Wadden Sea” is recommended]

5 TMAP Monitoring Strategy

The existing Joint Monitoring program of Breeding Birds (JMBB) have been successful for over 15 years and should be continued. The frequency for monitoring and reporting will be linked to the 6-year reporting period (in accordance with the HD, BD) by the bird expert groups.

(Table 5.1) Parameters with monitoring locations and frequencies and the relation to the other monitoring requirements.

b. Complete surveys of selected species
c. periodical counts of a larger range of species within the entire area.

Remarks:

5.1 Parameters

  • annual counts in a number of census areas,
  • complete annual surveys of (starting in 1990) (Fleet et al. 1992)
  • periodical counts of a larger range of species within the entire area. These total counts of the entire area will be repeated at five yearly intervals (1990, 1996,2001,2006...). The results are regularly published (Fleet et al. 1994, Melter et al. 1997, Rasmussen et al. 2000, Koffijberg et al. 2006).

5.2 Monitoring locations

The program on Monitoring Breeding Birds in the Wadden Sea "Numbers and distribution of breeding birds” includes:

  • selected census areas: at least two areas (four areas for Oystercatcher and Redshank)in each sub-region (The Netherlands, Lower Saxony, Schleswig-Holstein and Denmark),
  • periodical counts of a larger range of species within the entire area.

6 Methods

The detailed guidelines "Monitoring of Breeding Birds in the Wadden Sea” were published in the volume "Wadden Sea Ecosystem No. 3” (Hälterlein et al. 1995).

7 Parameter

Mandatory TMAP Parameters (covering entire intertidal area):

  • Number and distribution (breeding birds)

8 Frequency and time

Annual surveys of the colonial and rare breeding birds and annual counts in the census areas aim to detect population trends.

Every five years complete census of all selected species in the entire Wadden Sea during the breeding season (will be adopted to the framework of the BD).

For details see [Table 5.1].

9 Assessment

The ecological targets regarding breeding birds, as agreed at the Trilateral Governmental Conference in Leeuwarden (1994), will be used for the assessment in the Wadden Sea:

  • favorable conditions for breeding birds
  • favorable food availability,
  • natural breeding success,
  • natural flight distances.

10 Reporting

All data obtained from aerial and field surveys should be transferred to a geographical information system (GIS) for the analysis and assessment of the data (spatial and temporal development) and in combination with other GIS based information.

The frequency for monitoring and reporting will be linked to the six-year reporting period (in accordance with the HD, BD) by the bird expert groups.

11 Quality assurance

Every year a QAM is hold on different sites along the Wadden Sea coast to proof, test and discuss recent methods and practicability. Reports of these evaluation meetings are existing (Blew 2003).
