| cambium | In woody plants, the layer of living tissue between the bark and wood from which new bark and wood are formed. |
| camouflage | Colors, tones, patterns, shapes or behaviors that enable an organism to blend in with its surroundings. Some organisms, for example, have a skin or coat color that lets them hide from predators |
| canopy | The forest layer formed by the leaves and branches of trees or shrubs. There may be several canopy layers. |
| canopy cover | The cover formed by the branches, leaves, and stems of plants. Can specify as herbaceous, shrub, tree, or all canopy cover. |
| chlorophyll | The green coloring matter in plants necessary for photosynthesis. |
| chloroplasts | The structures within plants that contain chlorophyll and enable photosynthesis to occur |
| commercial forest land | A forest land that is either currently or prospectively |
| clearcut | accessible capable of bearing merchantable timber, not withdrawn from such use. |
| compound leaf | A leaf that is subdivided into many leaflets. A leaf that is comprised of a single leaf blade is a simple leaf. |
| cord | A volume measure of stacked wood. A standard cord is 4 x 4 x 8 feet, or 128 cubic feet of wood and space. A long cord contains 160 cubic feet and is 4 x 5 x 8 feet. |
| conifer | A plant that bears naked seeds in cones; usually refers to needleleaf trees, although some needleleaf, such as yew, do not bear cones. |
| coniferous | Refers to cone-bearing. A coniferous forest is one composed of pines, firs, or spruces. |
| crop tree | Any tree selected to grow to final harvest or to a selected size. Crop trees are selected for quality, species, size, timber potential, or wildlife value. |
| cutting cycle | The planned time interval between major harvesting operations within the same stand—usually within uneven-aged stands. For example, on a 10-year cutting cycle in a hardwood stand, trees are harvested every 10 years. |
| crown | The top branches of a tree |
| crown-class | A tree classification system based on the tree’s relative height, foliage density, and ability to intercept light. |
| crown-sprout | The ability of some plants to regrow after plant material above ground is removed by fire or other disturbances. |
| cruise | Measuring timber to determine the volume of a stand. Cruising shows landowners how much timber they are growing and is basic in determining how much timber should be marked for cutting and how much should be allowed to grow. |
| cull | A tree or log of marketable size that is useless for all but firewood or pulpwood because of crookedness,rot, injuries, or damage from disease or insects. |

| deciduous | Plants that annually shed their leaves; usually hardwood trees and shrubs |
| defoliation | The removal of leaves or needles from trees or plants, usually caused by insects, diseases, or chemicals and often causing mild to severe damage—even death—to the tree. |
| deforestation | The permanent replacement of forests by non-forest uses. |
| dendrology | A branch of botany devoted to the study of trees. |
| dendrochronology | The science of dating events and variations in the environment in former periods by the comparative study of growth rings in trees and aged wood. |
| dendrometers | An instrument used to measure trees |
| densimeter | A device used for measuring the density of the canopy cover. |
