Disappearing Dragonflies And Damselflies

0 28

A global decline in damselflies and dragonflies are happening as the wetlands (marshes, bogs and swamps) are declining. The report was published in International Union for the Conservation of Nature’s latest Red List of Threatened Species, after its first comprehensive assessment of this colourful group of insects.

The report says wetlands loss is due to urbanisation and unsustainable agriculture. Now 16% of dragonflies and damselflies are under threat of extinction.

Wetlands are an ecosystem in itself. They store carbon, give us clean water and food, protect us from floods, as well as offer habitats for one in 10 of the world’s known species. Unfortunately, these are are disappearing three times faster than forests. Assessments show that the world had lost 35% of its wetlands between1970 and 2015.This is because of the perception of wetlands as wastelands that need to be reclaimed, when actually they’re really important.

Experts hope that by showcasing these beautiful insects, and highlighting that we’re in danger of losing them, we can [spread the message] that we need to do more to protect the world’s wetlands.

With the latest red-list update, the number of species officially listed as at risk of extinction now exceeds 40,000.

Wetlands are areas where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year. Water saturation largely determines how the soil develops and the types of plant and animal communities living in and on the soil. Wetlands may support both aquatic and terrestrial species. The prolonged presence of water creates conditions that favour the growth of specially adapted plants (hydrophytes) and promote the development of characteristic wetland (hydric) soils.
