Etymology: Pinus: the ancient Latin name
Plants: perennial, 60'-90' tall, evergreen tree; stems higher ones bright orange
Leaves: needles 2 per cluster, 1.5-3" long, bluish
Fruits: 1"-2.5" cones
Invasiveness: Invasive - Eradicate!
Conservation Status: Introduced - naturalized; ecologically invasive
Primarily invading fields, pastures, and open, sandy or rocky areas; also on lake bluffs, around plantations, in old quarries, on Lake Michigan dunes, along roadsides and railroads, blufftops, and sometimes invading dry forests of oak-pine or mixed conifers.
This is a Eurasian species that was once irresponsibly planted for timber and to “improve” wildlife habitat; it has since spread to many dry, early successional habitats. Scots pine closely resembles jack pine, especially when young, and the two can be difficult to tell apart. The needles of Scots pine are more silvery, average a bit longer, and are sharply acute to abruptly acuminate at the apex while those of jack pine are green, shorter, and have obtuse to abruptly acute but blunt tips. Mature female cones of jack pine tend to point forward on the branches and are long-persistent; female cones of Scots pine are deciduous and horizontal or reflexed. First collected in 1954.
