Hmm. Pleasantly surprised to find Kerala being mentioned in this context - I wasn't aware of this.

But on a related note, the south west of India has a rich tradition of "Sarpa Kavus", literally, "Serpent Shrine", but which are in reality, sacred groves in some corner of the yard of many traditional homes (see [1] for a typical example) - these are mostly left to themselves for most of the year, except for a couple of festival days. In practice, it is almost a biome within the yard.
