Climate: Scrub (after some research, apparently most Mediterranean climes are classified as Maquis shrubland)
APM: Scrub is in fact the predominant biome of the Mediterranean area. I didn’t even know what Scrub climate was before I started writing the Auran Empire campaign setting.
For those of you who are presumable as ignorant as I was at the start of the process, imagine a ranked list as follows:
grassland → shrubland → woodland → forest
Shrubbland is land with woody shrubs. Shrubland is divided vertically into tall shrubland and low shurbland, and horizontally into open and closed shrubland.
Tall shrubland has 6’6" to 26’ tall shrubs and is generally known as “scrub”.
Low shrubland has 6" to 6’6" tall shrubs and is generally known as “heath”.
If the land is 70%-100% covered by shrubs, it is called “closed”. If it is 70% to 30% covered by shrubs, it is called “open”. If less than 30%, it’s probably not shrubland.
Each region has its own unique name for these territories:
Closed Scrub: Chapparal, fynbos, maquis, macchia

Open Scrub: Garrigue, phrygana, matorral, mallee, batha

(note how much more scattered the shrubs are, with gaps filled with grass)
Closed Heath: Heathland, Kwongan

(note how low, yet densely packed, the shrubs are)
Open Heath: Moorland

(low, widely spaced shrubs with moss and grass in between)
The Mediterranean region is primarily Closed Scrub and Open Scrub.
