Some comments:<br>><br>> 1) ISAO is apparently out of supplements and all they gave me was a<br>> photocopy of the list of species ratings. No worksheet. Anyone have a pdf of<br>> the whole supplement and wanna share?<br>> 2) Things started with native species on this site, and I'm very partial to<br>> keeping it that way. Of course, I'd also prefer stock from locally sourced<br>> seed. I chose *Ulmus americana* 'Princeton' because its apparently DED<br>> resistent, still the same species, and available in the client's area, even<br>> if it probably isn't genetically "local".<br>> 3) For sumac, in the absence of a worksheet, I'm leaning towards the species<br>> rating for Tree-of-Heaven (because of similar leaf shape, similarly<br>> soft-wooded, and its low rating).<br>> 4) Both "scrubby" and "tree form" Manitoba maples occur on the site. I like<br>> Alex's *Acer* alternates, and am also considering *A. saccharinum*.<br>> Basswood has also been suggested to me, I presume because its similarly<br>> soft-wooded and also inclined to be multi-stemmed).<br>> 5) Yes, big quotes take time to put together, but I definitely share Ian's<br>> opinion on this. Paying for one quote is one thing, but 3x or more can get<br>> pricey pretty quick. I think my future response will be to spontaneously<br>> levy a "quote administration fee" equal to the amount someone wants for<br>> submitting a quote. They probably won't like that one bit, but odds are that<br>> anyone who's that focused on profiteering isn't gonna be your lowest quote<br>> anyway.<br>><br>> Cheers,<br>><br>> Oliver K.
