| mangrove (Plant communities and trees that inhabit tidal swamps, muddy silt, and sand banks at the mouths of rivers and other low-lying areas which are regularly inundated by the sea, but which are protected from strong waves and currents. Mangroves are the only woody species that will grow where the land is periodically flooded with sea water; individual species have adapted themselves to different tidal levels, to various degrees of salinity, and to the nature of the mud or soil. Mangrove swamps and thickets support hundreds of terrestrial, marine, and amphibian species; have a special role in supporting estuarine fisheries; provide shelter, refuge and food for many forms of wildlife) | mangrove | |
| mangrove swamp (A wet, spongy area of land in tropical climates and along coastal regions that is dominated by mangrove trees and shrubs, particularly red mangroves (Rhizophora), black mangroves (Avicennia) and white mangroves (Laguncularia)) | mlaştină de mangrove | |
| manmade disaster | dezastru provocat de om | |
| manufacturing activity (Activities connected with the processing of raw material into a finished product, especially by means of a large-scale industrial operation) | activitate de fabricaţie | |
| manufacturing trade (The process or act of exchanging, buying or selling any manufactured product, or the raw materials for any manufacturing process) | comerţ cu produse | |
| manure (Animal excreta collected from stables and barnyards with or without litter; used to enrich the soil) | bălegar | |
| manure production (No definition needed) | producţie de bălegar | |
| map (A representation, normally on a flat medium, that displays the physical and political features of a surface area of the earth, showing them in their respective forms, sizes and relationships according to some convention of representation) | hartă | |
| map chart (A map, generally designed for navigation or other particular purposes, in which essential map information is combined with various other data critical to the intended use) | cartogramă | |
| mapping (The process of making a map of an area; especially the field work necessary for the production of a map) | cartografiere | |
| mapping of lichens (Maps of lichens distribution indicating air quality. Fruticose lichens (with branched structures well above the surface) are more susceptible to SO2 damage than foliose lichens (whose leaflike thallus lies nearly flat on surface) and both in turn are more susceptible than crustose lichens (which embed their tissue in the cracks of bark, soil, or rocks). The use of morphological lichen types as indicators of air pollution concentrations is well developed) | cartografiere a lichenilor | |
| maquis (A low evergreen shrub formation, usually found on siliceous soils in the Mediterranean lands where winter rainfall and summer drought are the characteristic climate features. It consists of a profusion of aromatic species, such as lavender, myrtle, oleander and rosemary and often includes abundant spiny shrubs. It has been suggested that the maquis is a secondary vegetation, occupying the lands cleared of their natural evergreen oak forests by human activity) | maquis | |
| marble (Metamorphic rock composed of recrystallized calcite or dolomite) | marmură | |
| marginal abatement cost | MAC | |
| marginal abatement cost | cost marginal al reducerii | |
| marginal land (Low quality land the value of whose production barely covers its cultivation costs) | teren marginal | |
| mariculture (Cultivation of marine organisms in their natural habitats, usually for commercial purposes) | maricultură | |
| marina (A small port that is used for pleasure rather than trade, often with hotels, restaurants and bars) | port de agrement | |
| marine biology (A branch of biology that deals with those living organisms which inhabit the sea) | biologie marină | |
| marine conservation area (Any section of a sea or ocean designated for special protection, often to prevent or reduce harm to its wildlife and ecosystems) | zonă de conservare marină |
