The Diomidous Botanical Garden in Athens
The botanical garden of Athens was reconstructed in 2004 to protect and maintain the biodiversity of the area. Covering a land of 1,860 sq.m., this Botanical Garden hosts over 2,500 different kinds of plants from all over the world and a rich variety of flora. All the plants and trees are protected in the park. The community also sends seeds all over the country to spread and maintain biodiversity throughout the region and hold agroecological events to increase the concern and educate the locals (Ref 1,3). The park also has a lake and a library inside it. (Ref 2)
Afforestation in the City of Aarhus
The City Council has passed an ambitious woodland plan designed to protect the municipality's groundwater.By planting woods in vulnerable areas where boreholes have been drilled for drinking water, the use of pesticides or other pollutants in the immediate area can be avoided. Aarhus residents will be ensured clean drinking water in 20 years even though the population is rising.(Ref. 2) New woodlands west of Aarhus will be a magnet for lovers of the open air, and secure clean drinking water for the city's population.(Ref. 1)
Curtain forest at the end of the city
The curtain forest at the end of the city is a project that was initiated by the Timisoara's Municipality in 2001 by planting different tree species and creating a barrier for high-temperature summers. It's 60 m high and it was designed to stand in front of very strong winds especially since Timisoara is a city located in a very plain area. Now, it comprises 23 hectares and the municipality aims at 50. (2)
