Ekka, from what I've seen, it appears that if they asked you to fix it, I'm bettin' on you.
I must admit though, at least you can get in to see the form, the US people won't even let you do that. I whole heartedly agree that the departments you mentioned SHOULD be doing the reporting. If your property tax system is like ours, the greenspace aorund your home will dictate property values. Who Benefits from increased property values, the councils. Here its not that the greenspace is taxed in the value of the home, but the resale of a nice yard supercedes one thats not.
If mother nature decides to teach us a lesson, she will always win. I personally like to see trees used to keep the revenue to the "man" in check.
If we reduce the wind off the heated buildings in the winter and can shade the house in the summer, utility consumption is dramatically reduced. Of coarse tree perform much more than wind and sun abatement, noise reduction is the one thing that trees perform well. We have a 2 row shelterbelt between the house and the highway (1/4 mile away). There is a dramatic differance between summer and winter tire whine from highway tractor trailers.
Its nice to have silence after hearing chainsaws and chippers all day.
