Magnolia Macrophylla (Magnolia)

Plant community:

Native status: Native to the Southeastern United States

Mature size (height & width):

Height: 30-40 ft

Width: 30-40 ft

Habitat/ Tolerances

The tree is rarely found in the wild, limited mainly to a few rich wooded areas in river valleys and ravines

Intolerant of urban pollution

No major disease or pest problems

Shade tolerance

Eco-indicator:

Hardiness zone: 5-8

Leaf color: Green leaves which turn yellowish brown in the fall

Flower color / bloom time: White with purple petals which come out in May

Response to Climate Change:

The tree has very particular habitat conditions which may make it difficult for it to grow with changing climate conditions.

Potential Climate applications:

The Magnolias intolerance to urban pollution and rare occurrence in forests limit its climate applications.

Climate adaption rank: -1

Oxydendrum arboreum (Sourwood)

Plant community: Oak Hickory Forest

Native status: Native to eastern and southern United States

Mature size (height & width):

Height: 20-50 ft

Width: 10-25 ft

Habitat/ Tolerances:

Drought intolerant

Pollution intolerant

Intolerant of urban conditions

Tolerant to wet conditions

Eco-indicator:

Hardiness zone: 5-9

Leaf color: Leaves are dark green and will turn a mix of red and orange

Flower color / bloom time: White blooms which some out in June and July

Response to Climate Change:

Massachusetts is predicted to become more suitable habitat for Sourwood trees. Population expected to increase locally.

Climate adaption rank: -2

Salt intolerant

Pest vulnerable

Eco-indicator:

Hardiness zone: 3-8

Leaf color: Dark green above and lighter green on the lower surface during the summer. Turn pale yellow in the fall.

Flower color / bloom time:

Pale yellow flowers which bloom in June

Response to Climate Change:

Habitat loss in the south and increase in the north

Northern migration

Climate adaption score: -3

Sources:

Acer saccharum (Sugar Maple)

Plant community: Northern Hardwood Forests

Native status: Eastern North America

Mature size (height & width):

Height: 40 - 80 ft

Width: 30 - 60 ft

Habitat/Tolerances: Often found in floodplains, forests, talus and rocky slopes

Salt intolerant

Drought intolerant

Drainage intolerant

Intolerant of urban pollution

Eco-indicator:

Hardiness zone: 4-8

Leaf color: Leaves are dark green in the summer and turn yellow, orange and red in the fall. Simple leaves, has lobes, can have teeth on edge

 Flower color / bloom time: Flowers are greenish and bloom around April

Response to Climate Change:

Due to the warming of native climates sugar maples may become less common in southern New England latitudes. The same trend is seen with sap production crucial to the maple syrup business. The tapping season is highly dependent on weather conditions and climate change is greatly impacting it’s productivity. Research has shown a decrease in sap production in southern areas and greater production in the north. 

 Maple trees need the insulating snow pack to protect its shallow roots from deeply frozen soil, without the snowpack the trees are projected to grow 40% slower. By the end of the century, snowpack could decrease by 95%.

Northward migration 

Expected to decline in population in current suitable habitat

 Potential Climate applications:

 Climate adaption score: -5
