Oh, don't get me wrong Ekka, I believe that there is someone to blame. With urban parks there is always politics going on. Here is a link to the gong-show that happened in Vancouver last year.
CTV.ca | B.C.'s Stanley Park loses 1,000 trees after storm
The Clay (as Ekka would say) still hasn't be sifted yet.
There are pages of related follow-up, Tree companies even volunteered to help and the city worker union put a STOP to that. Hence the term gong-show.
