Rehabilitation of Understocked Loblolly-Shortleaf Pine Stands—I. Recently Cutover Natural Stands [PDF]
Southern Journal of Applied Forestry, 1998 Abstract Two loblolly-shortleaf pine (Pinus taeda L.-P. echinata Mill.) stands were cut to stocking levels of 10, 20, 30, 40, and 50% to simulate recently cutover, understocked, uneven-aged stands. Number of trees ranged from 38 per acre for 10% stocking to 213 per acre for 50% stocking; comparable total basal areas were 4 and 16 ft²/ac,

Ecological functions of forest stands in urbanized environment of Moscow
RUDN Journal of Agronomy and Animal Industries, 2019 In urban forests, stock production is not the main function of stands. Carbon sequestration, the release of oxygen and phytoncides, dust precipitation, and changing wind conditions et al. are the main environmental functions.

Influence of umbrella pine (Pinus pinea L.) stand type and tree characteristics on cone production [PDF]
, 2016 Most umbrella pine (Pinus pinea L.) stands are managed as agroforestry systems, whose main production is fruit, due to the edible and highly nutritious kernels, and are frequently associated to natural or seeded pastures and grazing.
