"think the net effect is that you will have to register everything"
you forgot the (almost mandatory) "and pay the Govt a fee" part !
Wasn't there something a year or two back that suggested that because of the risk of insurance claims against home owners who had trees in their garden (said trees being a risk to passers by on the pavement, or neighbours having your tree damage their property - be it damaging car, house, person(s), pet(s) or just the garden itself) then we'd need to 'certify' each tree every few (3) years as being "sound" by hiring an arboriculturalist and paying 100 quid or more for a certificate per tree.
Think it is time I read the Reg article and contacted my MP, (hopefully) to raise some pertinent questions before this goes through, even if it is just doubt in the morality, among those MPs who might be expected (on party lines) to automatically support something (the way the Digital Economy Act got rushed through with obscene haste back in 2010, the day the announcement was made by Labour about the dissolution of Parliament and the forthcoming date for the Election. That was a rotten rubbishy bill and Act, and while a little was adjusted, it is still something I'd like to see revoked).
