Thiruvananthapuram,
Invasive species are considered the most serious threat
to biodiversity after habitat destruction. It is estimated that three
trillion dollars are spent every year across the world to manage the
menace. While most of the alien invasive species found in Kerala were
once imported for horticulture and agriculture, some reached the State
through timber consignments.
Studies carried out by
KFRI had revealed the presence of 82 invasive species in the State,
including trees, shrubs and climbers. High-risk species like the Nila
grass (
Mimosa diplotricha
) bracken fern (
Pteridium aquilinum
), Mucuna (
Mucuna bracteata
), Congress grass (
Parthenium hysterophorus
) and Chinese creeper (
Mikania micrantha
) can disrupt the growth of native species in forests, smother plants and trees and lead to crop loss and soil degradation.
