Estate agent Tom McClelland, who has died aged 64, was a man of many interests, with a passion for the environment and a campaigner to make the world a better place.
"He was a big man with a big personality and once you met him, you never forgot Tom," said his wife Kathryn.
The couple were married for 40 years and Kathryn was always at his side as he worked tirelessly to improve the environment now and for future generations.
"A colossus in working for the environment, cycling and road safety and a great family man," was how his friend, ex-BBC reporter Liz Fawcett, described him.
The colony of around 2,000 bats in the roofspace of the McClelland home at Dundrod is a reminder to family and friends of Tom's devotion to nature.
Tom, whose estate agency McClelland Salter is in Lisburn, was also passionate about cycling.
Tom's constant campaigning brought about much-improved cycle facilities in Belfast and across Northern Ireland.
It was largely due to his efforts that the National Cycling Charity was set up with a Northern Ireland branch, said Steven Patterson, deputy Northern Ireland director of the transport charity Sustrans.
Tom was a former chairman of the Ulster Wildlife Trust, and in business he was a respected spokesman for the Royal Institution of Chartered Surveyors.
Tom McClelland is survived by Kathryn, sons Matthew and James, daughters Ruth and Sarah, and seven grandchildren.
His funeral took place yesterday at Roselawn.
