Full title: Implementation of a monitoring program for vertebrate populations in forest environments in Guadeloupe: data acquisition and skills building (PROSPOVERG)

Aims: Identify the diversity of bird and mammal populations in a dry forest in Guadeloupe while training students in wildlife monitoring methods.

Location: Poyen Forest, Biological Reserve directed from the Nord Grande-Terre, Guadeloupe.

Dates: 2020-2023

Summary: The project consists of setting up a program to monitor and record the diversity of the population of birds and mammals (in particular invasive alien species) within a dry forest in Guadeloupe. It combines the implementation of a ringing and monitoring program by recapture and observations of marked individuals, with the simultaneous use of camera traps and acoustic recorders. The data obtained within the project will be used to calibrate future monitoring methods in dry forests in the West Indies. The project also aims to train students in modern methods of monitoring and studying wildlife.

Main results


Summary of the methodology:

Three methods for monitoring wildlife were deployed in eight sampling stations in the Poyen forest.

  • Capture-mark-recapture: capture of birds using nets (two 12 m nets per station, i.e. 16 nets in total), once a month for 24 months. The birds were measured, weighed and ringed to be recognized upon next capture
  • Acoustic recorders: only for 3 months, allowing species to be recognized on the basis of their song
  • Camera traps equipped with a motion detector, only for 3 months in parallel with acoustic recorders


Main results:

  • 27 bird species identified, including 18 species captured with a net
  • 777 birds ringed
  • 215 birds recaptured

Birds were monitored for a total of two years. During these two years, the three methods were deployed in the same places and at the same time for three months, allowing their effectiveness to be compared.
