The J. F. Costopoulos Foundation contributed to the maintenance and operational readiness of one of the fire stations of the J. & A. N. Diomides Botanical Garden. This task was one of the main priorities of the Garden as the two fire stations play a key role in protecting against forest fires.

The Julia & Alexander N. Diomides Botanical Garden cultivates, protects and exhibits a diverse collection of over 2,500 species of native and exotic plants from Greece and around the world, aiming at conservation, environmental education, research and recreation for the benefit of science and society. This activity is carried out in an area of ​​450 acres, which makes the Diomides Botanical Garden one of the largest in the world. The protection of the area, which has been designated in its entirety as a permanent Wildlife Refuge, is of utmost importance. This purpose is achieved through a series of measures implemented by the Administration of the Garden in collaboration with the State.
