# Natural history of Rhodes

The natural history of the island of Rhodes is determined by its geographic position, climate and geological diversity. Rhodes is in the Eastern Mediterranean Basin close to the coast of Turkey, and the flora and fauna are a mixture of Mediterranean and Asian elements. Rhodes is in the Eastern Mediterranean conifer-sclerophyllous-broadleaf forests ecoregion.
The habitats are: arable land; perennial crops, orchards and groves, ruderal land; coastline and coastal rocky areas, inland cliffs, sea cliffs and rocky shores: forest, native coniferous woodland; grassland steppes and dry calcareous grassland; shrub land, sclerophyllous scrub, garrigue and maquis shrubland; wetland, rivers and streams.

## Flowering plants
