The very wide range and abundance of Pinus echinata, which is actually spreading into abandoned farmland, indicate an assessment of Least Concern.

|Population:||Subpopulations are thought to be increasing as this species recolonizes abandoned farmlands.|
|Habitat and Ecology:||Pinus echinata is a lowland pine with an extensive range across the SE United States, mostly growing from ca. 150 m up to the foothills of the Appalachian Mountains at ca. 600 m a.s.l. It is absent in the Mississippi Valley and its delta as well as in a narrow to fairly wide coastal strip along the Gulf of Mexico and Atlantic Ocean, and it does not extend into most of Florida. This indicates that it is primarily limited by climatic factors, such as the 10º C average annual temperature isoline at its northern limit and an average annual precipitation above 1,000 mm distributed more or less evenly over a year as its southern limit. It grows on a great variety of soils, but most have a capacity for moist retention with a sandy loam or silty loam texture and good drainage. Although this species can form nearly pure stands, in most sites it will be succeeded by broadleaved trees especially oaks (Quercus spp.) except where thin soil overlies rock. There P. echinata forms a minor component of various angiosperm-dominated forest and woodland types. It can also be associated with P. taeda, which has a very similar distribution, but at least in parts of its range occurs in a wetter habitat.|
|Major Threat(s):||There are no recorded threats to this species.|
|Conservation Actions:||This species is known from several protected areas throughout its extensive range.|
