Ash die-back is getting closer– in Tresswell Wood, North Nottinghamshire, a wood dominated by Ash at present, ash die-back is really affecting the ecology. This is only 30 miles from Sheffield, and the Peak District where many of the large trees in the landscape are Ash. The Nottinghamshire Wildlife Trust notes how woods change over time– Elms were lost, and thousands of hazel rods were stripped out and used as handles for fire buckets during World War Two. Woods have a ‘high diversity index’ and can cope with some change but this feels troubling. Conditions: Mild and cloudy Temperature: Max 16- Min 12C.
