looking for recommendations for trees in "cold arid climate" (central WA)

Hey there folks! how are we all?

I am working out in Eastern Washington, Thorp in particular. If anyone out there is from the area, GREAT! if not, this means that we have a 8 month growing season march15-october 15th and then we get cold winters with temps down to 15F or -7C

I am starting to compile a list of trees and shrubs that could be used for various purposes on our new project. If anyone has a good resource for locating species specific plants for my particular area PLEASE send them my way. We have a large quantity of land with plenty of water. While our design process has yet to begin the rough idea is we want silvo pasture, Perennial food crops, and some till-less annual row crops with hedgerows. Sooooo i am looking for nut trees, fruit trees, berries, grasses and the like. Our overarching goal is carbon sequestration...btw.

I once heard a tale of a federal website that makes all sorts of agricultural recommendations for specific areas.. anyone know?

Thanks!!  

I like these two databases because they seem to have everything: Plants.USDA.gov and PFAF.org (which seems to be down right now). You can use the search options (advanced search in Plants.USDA.gov) and it will give you a list. Always double-check the list with internet search when it comes to something your not familiar with because just because someone things it is edible, doesn't mean you'll want to eat it. Like bananas and yogurt. Supposedly these things are edible raw, but I gag if a spoon full gets to close to my face.

Also, try an advanced search on this site (if you haven't already). What to plant is a common question here and someone may have found something that may interest you already.


Good luck!
