Fresh pine tree forests and forests mixed with deciduous plants can be found in the Reserve. Due to abundance of different species of pine, Mariamdjvari is an interesting object in terms od scientific research. Here are four forms of the pine: Pyramidal  (Pinus sosnowskyi Nakai var. pyramidalis Kurd.); Compact (Pinus sosnowskyi Nakai var. compacta Kurd.); Oval (Pinus sosnowskyi Nakai var. ovalus Kurd.); Umbrellalike (Pinus sosnowskyi Nakai var. umbraculifera Kurd.).
