Barbara Knowles obituary

My sister, Barbara Knowles, who has died aged 55, was an enthusiastic biologist, a scientific adviser to the Royal Society of Biology (RSB) and a champion of meadow ecology and sustainable development projects, especially in Transylvania.

She worked in the Poginy-havas region of the eastern Carpathians with local volunteers and experts to record and protect valuable flora and fauna. She established the Barbara Knowles Fund and supported activities working with schoolchildren, academics and policymakers.
