Not all non-natives are...

"We applied to build a barn to be sited on an arable field.  The council asked for a biodiversity appraisal, and placed a short deadline for receipt. We engaged Dr Chris Gleed-Owen who made a site visit within days, and delivered a fully researched report with plans, species list and recommendation a few days later, within the required timescale.  We have therefore avoided the need for extensions and delays.  Thank you Chris.
