Eastern White Pine is the state tree of several states. Maine made it theirs in 1945.  Of all the native conifers calling eastern North America home, this tree is the tallest.  It towers at 150 feet and lives as long as 450 years-sometimes longer.  It most likely used to grow even taller and older before the colonist arrived.  The current champion in Maine is 120 feet tall, has a trunk circumference of 245 inches, and a crown spread of 80 feet!

With over 80% of its land forested, Maine
is one of the best places to lose yourself in the quiet woods.  Pine, maple, beech, birch and oak are some of the more common tree species that make up Maine's forests.  One of the best ways to enjoy the scenery is hiking through the many trails throughout the state.  In fact, Maine has partnered with Center for Community GIS of Farmington to create a database of all state trails.  Housing some of the trails are Maine's 32 state parks and Acadia National Park, the only National Park in New England.  Acadia National Park is unique among

Limit of range- edge of distribution or disjunct from main distribution.
Population declining- seriously declining due to habitat modification or destruction, or from over collection for commercial,
  recreational, or educational purposes.
Population vulnerability- highly vulnerable to decline due to location or human usage.

Once a species is determined to fall into one of the above categories, it is then assigned rarity status by the state of as

Endangered- Rare and in danger of being lost from the state in the foreseeable future, or federally listed as Endangered.
Threatened- Rare and, with further decline, could become endangered; or federally listed as Threatened.
Special Concern- Rare in Maine, based on available information, but not sufficiently rare to be considered Threatened or
Possibly Extirpated- Not known to currently exist in Maine; not field-verified (or documented) in Maine over the past 20 years.

Rare tree species present in Maine (see related links for full list):

Special Concern:
Betula pumila, Swamp birch
Castanea dentata, American chestnut
Chamaecyparis thyoides, Atlantic white-cedar
Sassafras albidum, Sassafras

Quercus bicolor, Swamp white oak
Quercus montana, Chestnut oak
Salix myricoides, Blue-leaf willow
Salix planifolia, Tea-leaved willow
Native plant species considered rare in Maine meet one or
more of the following state categories:

Endemism- geographically restricted to the State or areas
  immediately adjacent to the State.
Few Populations- extremely small number of populations.
Few Individuals- numerically scarce, small number of individual
Special habitat- requiring habitat that is scarce in the State.

National Parks in that it contains mountains, lakes, rivers, ocean front and even islands!  In addition to that, one of the most famous trails in all of North America, the Appalachian Trail, ends at Mount Katahdin's Baxter Peak in Baxter State Park.
  Within the rugged forests of Maine lie valleys carved by ice streams passing through mountainous areas.  Glacial till, or leftover sediment and gravel, can be found just about anywhere.  Large rounded boulders are commonly found, seemingly out in the middle of no where, which were left behind as the glaciers retreated.  Enjoying the trees and trails of Maine also means nature lovers have a chance to see the geologic history of the area.  Bedrock exposures like the Knife Edge of Mount Katahdin, or wave swept bedrock at Pemaquid Point in Bristol, are a window into the Earth's violent past.  While walking among some of the tallest tree species in eastern North America, you may even glimpse 500 million year old remnant lava tubes, hardened into "pillows", Metamorphic rocks created by intense heat and pressure beneath the earth's surface, or stumble upon Maine's most famous mineral- tourmaline.  There are even public mines open for the latter!
   The forests of Maine really do harbor giants.  One of the most famous trees, Herbie, was the largest American Elm tree in New England.  It reached 217 years old before succumbing to disease and was felled in 2010.  The tallest tree in Maine is said to be a 135 foot tall red spruce located in Blanchard.  Other state champions (2010) include a yellow poplar, standing 129 feet, and a 126 foot eastern cottonwood.

2001, this giant from the 2010 Big Tree Registry is located in Morill.
   Eastern white pine's bark is smooth and gray on young trees, becoming broken into small plates when mature. The root system is deep, 40 inches or so, with spreading laterals and has no distinct tap root.  The needles are 3-5 inches long, bundled in 5's and
dark green.  They are soft, flexible, fine and persist to the second year. Beginning at age 5-10, curved, 4-8 inch long spine free cones start growing.  Male strobili open and disperse pollen from April to June, depending on location.  It will take 2 years for cones to mature.  Seeds are typical of pines in their small size, .08 inches, brown color and single winged.  Dispersal is from August to September.
