Shenandoah National Park and New Trees in Survey Plots

Shenandoah National Park and New Trees in Survey Plots

During forest monitoring, I added two new trees to documentation in a survey plot at Shenandoah National Park. Within the plots, trees are only documented as such if their diameter at breast height (DBH) is 10 centimeters or more. DBH is measured using a special measuring tape called a “DBH tape” that is calibrated for diameter using the equation where diameter equals circumference divided by pi. At 1.35 meters up from the highest point of ground at a tree’s base, the tape is wrapped around the tree at DBH, ensuring it is level and not kinked. The DBH measurement is obtained by reading where the measurement overlaps with zero on the tape. It was exciting to find that both trees met the requirements to now be monitored as trees in plot.

Both trees are Eastern White Pines (Pinus strobus), commonly found in the Virginia mountains and throughout eastern North America, ranging from Canada to the northern United States. In the field, identification of these trees is mostly based on their needle bundles (mostly groups of 5), and whorled branches. They have various uses, including landscaping, Christmas trees, and construction material for timber frame structures and colonial homes. These trees have a rich history and are known for their workability and versatility.

To ensure future observation of these trees, I attached unique tree tags with a specific code for each tree. These tags assist in ensuring the future monitoring of these trees, their code providing record of them in plot for the next monitors. As my first time documenting new trees, I named them Ananias and Sapphira, considering them as twins, one male and one female, even though they are a monoecious species.
