  • This is a young Bruguiera gymnorrhiza mangrove plant taking root in the shallow water of Long Lake, part of Ngeruktabel Island in Palau. These mangrove trees create an intricate network of roots, visible behind this young plant, that stablize and lock-in silt and mud, providing a buffer against erosion, as well as serving as shelter for juvenile fish and other marine animals.

  • This is a Pteromys volans orii flying squirrel carrying a small branch of Japanese elm (Ulmus davidiana var. japonica) back to its nest. This individual had spent over an hour in the early morning at the top of 20m tall elm trees feasting on fresh buds. This branch is a take-away meal for enjoyment back home.

  • Long Lake, part of Ngeruktabel Island in Palau, is home to a variety of plant life, including a dense forest of mangrove trees. This is a young Bruguiera gymnorrhiza mangrove plant taking root in the shallows. When mature, these mangrove trees create an intricate network of roots that stablize and lock-in silt and mud, providing a buffer against erosion, as well as serving as shelter for juvenile fish and other marine animals.

  • This Japanese flying squirrel (Pteromys volans orii) is perched on a comfortable, safe location high above the ground, where it is eating one of its favorite foods, the buds of a Japanese elm tree (Ulmus davidiana var. japonica). Normally nocturnal, these squirrels are sometimes active in the early hours of daylight.

  • Pictured here are male catkins of an Alnus japonica elder tree together with female cones. The male catkins comprise many flowers, which produce pollen to pollinate female catkins. Once pollinated, the female catkins develop into woody false cones as seen here. In the autumn the scales of the cones open and disperse their seeds. Male catkins of this species are among the favorite foods of Pteromys volans orii flying squirrels.

  • This is a Pteromys volans orii Japanese dwarf flying squirrel foraging at dawn. It is high in the canopy, around 15-20m, not far from its nest. The tree is a Japanese elm (Ulmus davidiana var. japonica), one of several prime food sources for this species. As seen here, these flying squirrels consume the leaf buds of this tree.

  • During the breeding season, male Japanese dwarf flying squirrels (Pteromys volans orii) sometimes confront one another, usually in the context of competition for a female. Here, the one above has just snuck up behind the individual below, which made a quick turn to look up at the intruder. The animal looking up was in the midst of enjoying a snack, the flowers of a Japanese alder (Alnus japonica) that are visible in his mouth. A frantic battle between the two males soon ensued.

  • This is a Pteromys volans orii flying squirrel returning to its nest at dawn after foraging high in the canopy during the night. It is carrying a small branch with leaf buds of a Japanese elm (Ulmus davidiana var. japonica), one of several prime food sources for this species.

  • Long Lake, part of Ngeruktabel Island in Palau, is home to a variety of plant life, including a dense forest of mangrove trees. Pictured here is a portion of the thick, intertwined network of Bruguiera gymnorrhiza mangrove prop roots that are submerged during high tide, but partially exposed during lower tides. These roots are key to the survival of the trees, but also serve as shelter for juvenile fish and other marine animals. The intricate network of roots also stablize and lock-in silt and mud, providing a buffer against erosion.
