L’expérimentation de transplantations réciproques (RTE) a été installée dans la vallée des Gaves (Hautes Pyrénées). Les sites de transplantations ont été choisis à 5 altitudes différentes, de 100 m à 1600 m. Tous les sites de plantation ont été sélectionnés en versant Nord pour minimiser les effets microclimatiques lors de la comparaison inter-altitude.
Dans chaque site de transplantation et pour chaque espèce, deux modalités de traitement ont été choisies : transplantations en milieu ouvert (trouée) et milieu fermé (sous la canopée de la hêtraie) et 4 répétitions (bloc) ont été installé par modalité. Pour chaque population (3 par espèce), 32 plants ont été transplantés dans chaque site (16 par modalité ; milieu ouvert et en milieu fermé), soit 192 par site et 960 plants au total le long du gradient. Par bloc, les plants ont été plantés selon une disposition de type systématique.  Chaque bloc est protégé des grands herbivores par un grillage. Un mois avant la plantation, un désherbage chimique a été effectué,...
