When selecting a tree to plant, make sure to check its cold hardiness rating to see if it can tolerate the minimum winter temperatures of your locale.
The 2012 USDA Plant Hardiness Zone Map shows that the planting zones for Westchester County are 6b and 7a. The northernmost communities have colder winter temperatures, and therefore are in Zone 6b. New York planting zones range from 3b (coldest winter temperatures in NY) to 7b (warmest winter temperatures in NY). Check the hardiness zones for which the tree you are considering is rated. For example, according to the Cornell School of Horticulture’s Woody Plant Data Base, a white oak tree (Quercus alba) is “hardy to Zone 3b”. This means that the tree can be planted in zones as cold as Zone 3b, and in all warmer zones in New York, that is Zones 3b,4a, 4b,5a,5b,6a,6b,7a, and 7b.
Plant trees that can cope with our changing climate
Due to our changing climate, scientists have predicted which species of trees will thrive in Westchester in the future. The US Forest Service Climate Change Tree Atlas provides the results of modeled potential suitable habitat for 125 tree species in the East. The species list for Westchester County can be found in the Urban Areas List. Use the Woody Plant Database to learn about each species listed in the Climate Change Tree Atlas.

Description: Urban area 63217, New York, New Jersey, and Connecticut is the selection for Westchester County. The USFS recommends selecting species currently present (often common or abundant) that are likely to cope with the changing climate: for these species, we simply select among those with a Fair, Good, or Very Good capability to cope under low (Capabil45) or high (Capabil85) emissions.
Below is the list of recommended native trees that are predicted to cope well with climate change in Westchester County.
