What is lost

Is the heat really such a problem? Who needs fish and plants anyway?

The UK’s hottest June on record caused unprecedented deaths of fish in rivers and disturbed insects and plants, environment groups have warned. Nature is being “pounded by extreme weather without a chance to recover”, the Wildlife Trusts said.

“The reports of the number of fish death incidents in rivers for this time of year has been unprecedented. I would normally expect rivers to be affected later in the summer when it’s hotter and drier,” Mark Owen, from the Angling Trust, told BBC News. In one case, sea trout were found dead on the River Wear in north-east England, he said.

The deaths are partly caused by less oxygen in the water as river levels decrease. Fish also die when dried-up pollutants from cars and lorries on roads wash into rivers during flash storms. The Environment Agency said it received more reports of dead fish than the same time last year.

Many flowering plants, including orchids, wilted in the high temperatures, meaning insects like bees and butterflies that feed on nectar and pollen will have less to eat, Ali Morse from the Wildlife Trusts told BBC News. Species with short lifespans are particularly badly affected. Many butterflies are adults for only a short time, and if they cannot access food in that period, it stunts the population.

The race to the edge of the cliff continues.
