🌲 Tree Talk Tuesday: The eastern white pine (Pinus strobus) 🌲
🌲The eastern white pine (Pinus strobus) is a tall, fast-growing conifer originally native to the Northeast, upper Midwest and Appalachian regions of Eastern North America. The white pine can grow over 200 ft in height and over 7 ft in diameter, making it the tallest and largest pine tree native to Eastern North America. It has been widely introduced outside its natural range for use in windbreaks, timber plantations and reforestation efforts due to its fast growth rate and tolerance of poor, highly eroded soils. The Civilian Conservation Corps frequently utilized white pine in their reforestation efforts during the 1930s, and if you come across a large stand of white pine on public land, it's likely that the trees date to this time. The photos included in this post are of old-growth white pines in Porcupine Mountains State Park, in the Upper Peninsula of Michigan.
🪵Old-growth eastern white pines were highly prized during colonial times for their incredibly tall trunks, which were in high demand for use as ship masts. Prior to using white pines as ship masts, the royal navy relied on Baltic pines (Pinus sylvestris) imported from the Baltic nations of present day Estonia, Latvia and Lithuania. However, it became increasingly difficult to keep the Baltic trade routes open during the 18th century due to military and political conflicts in the region and thus the Crown came to rely heavily on eastern white pines for their ship masts.
📜To reserve old-growth white pines for royal navy ship masts, several colonies passed “broad arrow policies”, with Massachusetts being the first in 1691, and other colonies including New Hampshire and New York following suit. These laws made any white pine over 24 inches in diameter (later changed to just 12 inches) the property of the Crown, even if the trees were on private land. These pines were marked with broad arrows by “Surveyors of the King’s Woods.” The broad arrow mark made it illegal for any colonist to harvest and sell the timber of these trees.
🇫🇷🇪🇸While these policies were rarely enforced in the early 18th century, as the Baltic timber trade declined, colonial governors such as Sir John Wentworth of New Hampshire increased enforcement in the early 1770s. Colonists were outraged by the policy because white pines were the most valuable timber on their lands, and England was not the only country in need of white pine. Both France and Spain also prized white pine for ship masts and colonists could fetch a far higher price by selling to those nations rather than England.
Tensions rose and on April 13th, 1772 Benjamin Whiting, the Sheriff of Hillsborough County, New Hampshire and his deputy executed a warrant to arrest Ebenezer Mudgett, a sawyer for illegally harvesting and selling white pines. Ebenzer was released when he agreed to provide his bail the next morning. That night, the Sheriff and his deputy were staying at a local tavern, the Pine Tree Inn, when Ebeneezer and 30 angry colonists disguised with soot on their faces broke into the Sheriff and his deputy’s rooms, beat them with tree branches and lashed them 20 times, one lash for each white pine that Ebeneezer was accused of stealing from the Crown. They then took the two men’s horses and cut off their ears, manes and tails and sent the sheriff and his deputy off on the maimed horses.
🇺🇲This incident became known as the “Pine Tree Riot” and was one of many incidents between colonists and British authorities that led to the American Revolution. The white pine tree consequently became one of the many symbols of the American Revolution, and it soon became prominently displayed on “Pine Tree Flags” of American naval vessels and colonial militias during the American Revolution; a pine tree flag was noted as being flown at the Battle of Bunker Hill. To this day, the official maritime ensign of Massachusetts and Maine is the pine tree flag, and Maine and Vermont both feature a white pine tree prominently in the center of their state flags.
🌲White pine is highly ornamental and may be planted in a variety of soil types. Planting a row of white pine trees along a property line can provide year round privacy from your neighbors as well as beautiful evergreen foliage. They provide excellent contrast during fall when planted among other deciduous trees with yellow, orange and red fall color. While increasing summer temperature and more frequent droughts are increasing the vulnerability of white pines to diseases such as white pine blister rust, planting a white pine in a cool, moist, sheltered location, such as a north or east facing slope can help to ensure that they will thrive. While Hill House doesn’t currently have any white pines in stock, they are widely available as seedlings from state forestry departments and in traditional nurseries. Plant this symbol of the American Revolution in your yard today!
