Red light for night walking
August 13th, 2009
Left to their own devices, your eyes can adapt to the darkness by producing a photosensitive chemical called rhodopsin. But once you turn on the torch the rhodopsin breaks down and your built-up night vision is lost. That’s why a headlamp with a red light setting is strongly recommended for night time activities. Red light is enough to read a map, but won’t leave you blinded. The Ramblers Association has a list of head torches of all shapes and sizes, like the recommended Petzl e+LITE pictured above.
The oldest osprey of the UK – and probably the world – has returned to her eyrie in the Scottish highlands. When she left for West Africa at the end of last summer, no one expected her to return. At 26 she’s lived 3 times longer than most female ospreys. In her life she’s laid 58 eggs and hatched 48 chicks, a massive individual contribution to the survival of ospreys in Scotland, where there are still only about 200 breeding pairs. The questions now are if her mate will return and if she is still fertile. Events can be followed on the 
Otters, water voles and fish are all benefitting from the improved quality of the UK’s waterways, now described as the cleanest since the industrial revolution. Since almost disappearing from the wild in the 1970s, otters are thriving, particularly in the south west of England, Cumbria and Northumberland. The population of water voles, highly precarious in the 1990s, is also beginning to recover. The good results of stricter pollution controls and extensive conservation work are set to continue in the new year with the introduction of new European water quality directives.
