Kole Wetlands

Kole Wetlands Latest News

A recent scientific study conducted at the Kole wetlands, a Ramsar-listed ecosystem in Kerala, has documented a total of 12 species of pygmy grasshoppers.

About Kole Wetlands

The Kole wetlands are located in Central Kerala, that spreads over Thrissur and Malappuram districts.
It is popular for its paddy cultivation that dates back to 300 years.
The wetland gets its name from its high productivity – ‘Kole’ literally translates to ‘bumper crop’ in Malayalam.
The Kole areas are low-lying and have a central, narrow strip covering a long expanse, with many pockets running into cultivated land on either side.
The region is naturally subject to saltwater ingression. During the monsoon, the entire region, which gets submerged under water, is cultivated by draining the water and by erecting bunds.
As Kole is a large sprawling wetland with human habitation all around, there are coconut and arecanut plantations, gardens, and cultivated plants.
It is one of largest, highly productive, and threatened wetlands in Kerala.
It comes in the Central Asian Flyway of migratory birds.
In terms of the number of birds, the Kole Wetlands is the third largest in India after Chilika Lake in Orissa and Amipur Tank in Gujarat.
It has been recognised as one of India's Important Bird Areas by BirdLife International.
It was declared as a Ramsar site of international importance in 2002.

What are Pygmy Grasshoppers?

They are any of about 1,400 species of insects (order Orthoptera) that are small (about 15 mm [0.6 inch] long), brown, gray, or moss-green, and related to true grasshoppers.
However, the pygmy grasshopper has the forewings either reduced to small pads or absent.
The pygmy grasshopper is distinguished from the short-horned grasshopper by its practice of depositing its eggs singly in small grooves in the soil, rather than in underground chambers.
It is abundant in fields containing short grasses and on muddy shores.
Many species are dimorphic, having both a short form with reduced hindwings and a long form with functional hindwings.
Sound-producing and hearing organs are absent in pygmy grasshoppers.
