The refuge hosts the largest nesting population of leatherback sea turtles under US jurisdiction. Since 1981 Earthwatch volunteers have assisted in translocating leatherback nests that are in erosion zones and providing a presence to deter egg poaching. Over 350 leatherback nests may be laid during the nesting season. In addition, hawksbill & green turtles nest on the refuge. Sandy Point has the longest beach area in the US Virgin Islands. The peninsula that forms the refuge has fairly stable geologic formations, but the beach is highly dynamic. The salt pond that is partially contained within the refuge is the largest in the US Virgin Islands. Plant diversity is low because of salt stress. A deciduous forest is found on the refuge, however thorn woodland and salt-tolerant vegetation dominates. A wide variety of seabirds, shorebirds and songbirds use the refuge. This refuge is one of the few place you may find the West Indian Flamingo. An important archeological site dating back to 800 AD is on the refuge.
