Kaavu

The sacred groves or forests (kaavu) is perhaps the oldest eco-friendly project of ancient Kerala. The evergreen forests with temples within them used to be considered sacred and protected . There was a more earthly reason for this. The kaavu normally was surrounded by paddy fields ( most important agricultural crop). The birds which made the kaavu their home feasted on the vermin from the fields, thus ensuring crop protection and plentiful harvest. The forests also helped in water conservation, and conservation of plant species especially medicinal herbs.

Poomully mana still keeps the kaavu in its original state which describes the mana's commitment on preserving the heritage and ecofriendly activities.
