LTOA Bats and Woodland Training course 3 March 2016

Richard Edwards who attended the first bat and woodland course for full LTOA members said "It was a really interesting day, the morning indoor sessions cover British bats, protected species and wildlife law, and tree/woodland management, including a look at the essential Bat Surveys – Good Practice Guidelines and the new BS 8596:2015 British Standard Surveying for bats in trees and woodland Guide.

The afternoon session is a walk round Cherry Tree Wood, East Finchley using various pieces equipment to look at bat habitats and potential roost features.

A big thank you to Sue Morgan and David Mitchell who ran the course. Sue’s knowledge on bats was complimented by David’s practical approach to woodland management and their enthusiasm for the subject made this a really useful day. Sue’s impression of a bat makes it worth attending for that alone.

I would also like to thank Andy Tipping, Barnet’s Trees and Woodland Manager, for providing an excellent venue".

On behalf of the Forestry Commission, the London Tree Officers' Association (LTOA) surveyed 2,979 London plane trees (Platanus x acerifolia) in 2014 for symptoms of C. platani. Inspections were undertaken at 53 sites across 28 London boroughs. More than half of the sites surveyed included potential hosts planted during the past 10 years, and the sites ranged in size from a minimum of 20 to, in some cases, more than 200 trees. No positive findings of C. platani were detected in any of the trees inspected.
