Tahiry Langrand

Tahiry Langrand joined the Global Environment Facility Secretariat in February 2025 as an intern with the Programming Division.

He recently completed an MSc in biodiversity, conservation, and management at the University of Oxford, where his dissertation assessed forest bat responses to land-use changes in the biocultural landscapes surrounding Ranomafana National Park, Madagascar using bioacoustics.

From 2021 to 2023, Tahiry conducted field research in Madagascar. Most recently, he surveyed birds and bats in Makira Natural Park as part of the Search for Lost Species effort led by Re:wild, the Wildlife Conservation Society, the Peregrine Fund, BINCO, and the RIDGES foundation. Tahiry has published on Malagasy moist evergreen forest ecology with Association Vahatra, with whom he worked in Marojejy, Ranomafana, and Andohahela National Parks, contributing samples to the Bird 10,000 Genomes (B10K) Project to enhance scientific understanding of avian biology and evolution.

Tahiry’s fieldwork extends to Mauritius, Costa Rica, and the United States. With the Mauritian Wildlife Foundation, Tahiry surveyed endemic forest birds, seabirds, and reptiles, and assisted in rewilding and restoration efforts on Round Island and Île aux Aigrettes. Tahiry conducted seabird research and science communication work on Año Nuevo Island, California, with Oikonos, and in 2019 he assisted parataxonomists with collecting butterfly and moth larvae in the Área de Conservación Guanacaste, Costa Rica contributing to a DNA barcode library.

Tahiry has internship experience with Biomimicry 3.8, Conservation X Labs, and Conservation International. He also holds a BS in sustainability, a minor in Spanish language studies, and a certificate in biomimicry from Arizona State University.
