Involving local Citizens in Biodiversity Monitoring –Through Bird Population Monitoring
Mooketsa K. & Senyatso K., BirdLife Botswana, Botswana
1. INTRODUCTION
Birds have many characteristics that make them good environmental indicators, e.g their abundance, diversity, ease of identification1.
BirdLife Botswana’s work has focused on monitoring and conserving globally threatened birds in Botswana.
Yet, there may be declines of “common” bird populations without our knowledge.
In response to this BirdLife Botswana has been implementing a Bird Population Monitoring Programme (BPM) aimed at developing a wild bird index for Botswana1, 2, 3.
BPM seeks to demonstrate that birds can be useful at showing ecosystem changes where they occur.
It is part of the global effort to monitor terrestrial birds around the world.
Since the BPM establishment in there have been five counts undertaken by surveyors (See Fig. 1-3 for the BPM growth).

2. BPM OBJECTIVES
1. To produce science-based evidence that will:
Develop a wild bird index and show bird population trends for Botswana
Help set conservation priorities and guide relevant legislation
Report on the state/change of Botswana’s biodiversity (including National reports to the Convention on Biological Diversity and DEA’s Environment Information System).
2. To build the capacity of Batswana and increase the level of community participation in wildlife monitoring.
6. Challenges
Transfers/relocation of BPM programme regional coordinators, and transect surveyors.
Bias of counters near cities and towns; remote areas still insufficiently surveyed.
Insufficient support materials e.g. Global Positioning System (GPS) Units, bird guide books, binoculars e.t.c.
Low level of bird knowledge (so, bird records in some transects may not truly represent the total number of birds that were present during the individual transect visits).
Some incorrect records reporting species outside their known distribution.
Some transects are often not repeated.
3. METHODS
Point counts are used located at regular intervals along a 2km transect.
Birds are counted along this 2 km transect, stopping every 200 m to record all the birds seen or heard for five minutes only.
Counts are undertaken twice annually (February and November).
7. RECOMMENDATIONS
Host training, recruitment and feedback workshops to discuss challenges and progress.
Procure support materials and put them at central places for easy access.
Regional coordinators to regularly conduct bird identification training courses for the BPM surveyors.
Produce more promotional/motivational materials and source funding for the programme’s sustainability.
4. IMPLEMENTATION PROCESS
The BPM programme implementation process involves:
1. A dedicated programme coordinator to:
Contact the surveyors to remind them to undertake transects counts.
Collate data, analyse and write feedback reports to surveyors.
Publicise BPM by writing articles before and after the count and send to media.
Produce motivational materials for the surveyors (e.g. t-shirts, posters and bird call CDs).
Share update reports with stakeholders through meetings, to solicit guidance on improving the BPM.
2. Regional BPM coordinators to:
support the surveyors in their regions.
3. Data management personnel.

3. BPM is Implemented in collaboration with the government departments, the Department of Wildlife and National Parks (DWNP) and the Department of Environmental Affairs (DEA).

Notes
5. RESULTS
Nationally, with the data that the surveyors collect, the distribution, diversity, abundance, composition and population trends of birds of Botswana is portrayed.
For example, Figure 1-3 shows the BPM growth in terms of the number of surveyors, transects and common birds.
