Obviously, we want to plant trees that are hardy in our local climate. No use in planting something that has no chance of survival. Check the local climatology of the target planting location on this map and compare this to the hardiness criteria of the contemplated species. Also, in addition to planting to mitigate climate change, are there any other purposes the trees are to serve, such as shade, fruit bearing, windbreaks, etc.? Trees planted for windbreaks can reduce heating energy requirements as shown here.  And shade trees can reduce summer cooling loads as shown here. You may also want to consider how rapidly your trees will grow. If planting for a windbreak, for example, you may want to plant fast growing trees to get the benefit of energy reduction sooner. Bear in mind that generally the faster growing trees have a shorter life span and slower growing trees live longer and sequester more carbon once they are mature. If trees are
