Conservationist in Your Backyard

Nature has the ability to self-sustain. It fulfills its needs by assigning roles to the specific species existing in the biosphere. One of the most significant needs it has is of conservation and this role has been assigned to the ubiquitous family of grasses (Gramineae) found in all our backyards.

Yes, the ‘Durva’, the ‘Citronella’, the ‘Napier’ and many lesser known ones like ‘Tachila’ are the natural conservationists. These monocots bind the soil tightly, prevent erosion and stabilize the soil on erodible slopes. In addition to this the grasses trap moisture under their dense growth, they provide habitat to countless invertebrates (worms and insects) and sustain micro-climates. They grow rapidly and their cast-offs create humus which helps in soil restoration. The hardy grasses are great agents of bio-remediation and pollution control as well. ‘Vetiver’ famous for its fragrant essential oil is an Indian native which grows in harsh conditions and absorbs the soil contaminants. It has shown its worth in most polluted soils near industrial areas.

Grasses have an important role as a pioneer species in ecological succession as well. They help in colonizing new lands after lichen by modifying the soils. This helps in making the land suitable for germination of other herbs, shrubs and trees. This soil modification service is immensely helpful in restoration of degraded lands too. It has been successfully put into practice on lands where mining has been done.

Grasses provide a win-win scenario for their use in conservation because apart from their characteristic hardiness and conservationist features their easy availability and economical potential make them attractive for multipurpose usage. For example: ‘Vetiver’ for its scented essential oil and raw material for handicrafts. ‘Anjan’, ‘Napier’ etc. for its use in animal fodder. ‘Lemon grass’ for its flavoring. ‘Bermuda’ grass for its use as turf grass and ‘Broom’ grass for making the brooms. ‘Guinea’ grass as a green manure along with other uses. All these grasses make conservation an economically feasible practice. Thus, it’s a win for environment as well as the economy.

So, next time you are walking on that ‘Bermuda’ grass, chilling on your turf don’t forget to acknowledge the important work the conservationist in your backyard is up to.
