<description>"Primary and secondary land" is land that is not in use as crop land or pasture land, including forests, grasslands, bare ground and vegetated wetlands. "Primary land" is land that has not undergone lulcc (land use or land cover change) due to human disturbance. "Secondary land" is land that has previously been used for agriculture, urban development or logging and has subsequently been abandoned. Reference: Hurtt et al. (2011), Climatic Change, 109 - 117, Harmonization of land-use scenarios for the period 1500–2100: 600 years of global gridded annual land-use transitions, wood harvest, and resulting secondary lands, doi: 10.1007/s10584-011-0153-2. "Primary and secondary land" refers to land use or management, rather than to specific categories of vegetation cover, e.g. the primary and secondary succession of plant species.</description>

<description>A primary forest is a naturally regenerated forest of native species, where there are no clearly visible indications of human activities and the ecological processes are not significantly disturbed. Reference: 'Global Forest Resources Assessment: Terms and Definitions', Forestry Department of Food and Agriculture Organization (FAO) of the United Nations, Rome 2010, www.fao.org/forestry/14241-0d7b74f45b0d2cfef31599cc17e4c28cd.pdf. Deciduous trees lose their leaves seasonally, for example, during winter in high latitudes or following seasonal variations in rainfall.</description>
