Action IP5 : Implement management actions on introduced species
As part of the France Relance plan aimed at regulating populations of introduced small mammals, the islet of Tintamarre was subject to a trapping operation between July 2022 and October 2023. In total, 150 automated traps were installed and have accumulated 7,500 activations to cover two-thirds of the islet. The deployment strategy consisted of initially positioning the traps in the first and then in the second third of the islet, before transferring them to the last third in September 2023 for the final phase of the project, scheduled until the end of February 2024. The first indicators of success for this initiative are notable: no more complaints from campers, and the absence of rat tracks on the beaches. Although these observations are promising, a more in-depth evaluation of the effects on the flora will be carried out during the next floristic inventory in two years, thus allowing for the assessment of the long-term impact of this regulation on the ecosystem of the islet.
