So many good people trying to make the world better! Each one has their own area of action. It may be health, sports for kids, peace, housing, justice, the environment, art, teaching school. You name it. Today’s story is on people doing something about the effects of global warming where they live — along Scotland’s rivers.
Severin Carrell reports at the Guardian that “millions of trees are being planted beside Scotland’s remotest rivers and streams to protect wild salmon from the worst effects of climate heating.
“Fisheries scientists have found rivers and burns in the Highlands and uplands are already too warm in summer for wild Atlantic salmon as they head upstream to spawn, increasing the threat to the species’ survival.
“Fisheries on the River Dee in Aberdeenshire, one of the country’s most famous salmon fishing rivers, have planted 250,000 saplings along key tributaries. They plan to plant a million in the Dee’s catchment by 2035. …
“In 2018, the year Scotland recorded the lowest rod catch for salmon since records began, climatic changes meant water temperatures in 70% of salmon rivers were too warm for at least one day that summer. They exceeded 23C [73.4 Fahrenheit], a temperature that induces stress and behavioural change. …
“Marine Scotland scientists found that only 35% of Scotland’s rivers, which stretch for 64,000 miles (103,000km), have adequate tree cover.
“Lorraine Hawkins, the river director for the Dee District Salmon Fishery Board, a statutory body, said: ‘These rivers and burns are the nursery grounds for young fish and it’s the young fish which will be affected by summer temperatures – their feeding and growth rates are affected. If it gets hotter, we will see fish dying.’
“Fishery boards across Scotland have similar tree-planting programs, to provide essential shade to lower water temperatures. Many will be fenced off to prevent the saplings from being eaten by deer. Hawkins said these projects improved the overall health and biodiversity of rivers across the uplands, increasing insect life, leaf fall, managing essential nutrients and flood control.
“Alan Wells, the director of Fisheries Management Scotland, an industry body, said climate forecasts were clear that water temperatures would continue to climb, even if governments succeed in limiting climate heating. …
“He said, ‘This will get worse. We need to grow trees now to create that cooling shade.’
“The dramatic decline in wild salmon numbers is blamed on numerous factors: climate change affecting food availability; weirs and other obstructions in rivers; predation by soaring seal populations; sea lice attracted by fish farms; bycatch by trawlers at sea and poor river quality. Wells said that while Scottish ministers were proposing new conservation strategies, he remained frustrated with the slow pace of change.
“The Dee marked the start of its angling season [in February] by inviting two female anglers who won a fundraising competition last year to make the first cast, an annual ceremony at Banchory. …
“Camryn Stewart, 14, one of the first cast fishers, said she had been brought up fishing by her parents, Deirdre and Jim. The sport is targeting women and children as it strives to expand its participation and appeal. …
“ ‘I have been surrounded by people who fish, and I’ve wanted to fish all my life,’ she said. ‘We need more people fishing. … We gain so much from it. Just being outside and being in the wild. Even if you don’t catch anything, you come back from the day fulfilled.’ ”
