| mid seral species | Shade intolerant species, primarily Douglas-fir trees and vine maple shrubs. These species typically follow the early seral species in natural succession. (05 Dec 1998) |

| mid seral treatment | A treatment in which a stand of predominately mid seral species will be established. (05 Dec 1998) |
|---|---|
| early seral species | <plant biology> Shrubs, such as ceanothus, and hardwoods, usually in tree form, such as red alder, bitter cherry and big leaf maple. These species start growing in natural succession soon after a disturbance (fire or logging). (05 Dec 1998) |
| late seral species | Shade tolerant species, primarily vine maple shrubs and western red cedar and western hemlock trees. These species follow the mid seral species in natural succession. (05 Dec 1998) |
| mid | 1. Denoting the middle part; as, in mid ocean. "No more the mounting larks, while Daphne sings, Shall list'ning in mid air suspend their wings." (Pope) 2. Occupying a middle position; middle; as, the mid finger; the mid hour of night. 3. Made with a somewhat elevated position of some certain part of the tongue, in relation to the palate; midway between the high and the low; said of certain vowel sounds; as, a (ale), e (ell), o (old). <prefix> Mid is much used as a prefix, or combining form, denoting the middle or middle part of a thing; as, mid-air, mid-channel, mid-age, midday, midland, etc. Also, specifically, in geometry, to denote a circle inscribed in a triangle (a midcircle), or relation to such a circle; as, mid-center, midradius. Origin: AS. Midd; akin to OS. Middi, D. Mid (in comp), OHG. Mitti, Icel. Mir, Goth. Midjis, L. Medius, Gr, Skr. Madhya. Cf. Amid, Middle, Midst, Mean, Mediate, Meridian, Mizzen, Moiety.

| mid-atlantic region | A geographical area of the united states comprising the district of columbia, delaware, maryland, new jersey, new york, and pennsylvania. (12 Dec 1998) |
| seral stages | The series of relatively transitory plant communities that develop during ecological succession from bare ground to the climax stage. (05 Dec 1998) |
| late seral treatment | A treatment in which late seral species will be established after thinning. (05 Dec 1998) |
| candidate species | <ecology> Any species or subspecies of bird, mammal, fish, amphibian, reptile, or plant that is being considered for listing as endangered or threatened but is not yet the subject of a proposed rule. (16 Dec 1997) |
| management indicator species | A species whose habitat requirements most reflect those of the species community in the habitat of concern, usually used to indicate habitat quality and to predict future conditions. (09 Oct 1997) |
| rare species | A species of animal or plant that is considered rare, threatened, or endangered. (17 Dec 1997) |
| reactive oxygen species | Reactive intermediate oxygen species including both radicals and non-radicals. These substances are constantly formed in the human body and have been shown to kill bacteria and inactivate proteins, and have been implicated in a number of diseases. Scientific data exist that link the reactive oxygen species produced by inflammatory phagocytes to cancer development. (12 Dec 1998) |
| sensitive species | <ecology, zoology> Species that can only survive within a narrow range of environmental conditions and whose disappearance from an area is an index of pollution or other environmental change. Those species which rely on specific habitat conditions that are limited in abundance, restricted in distribution, or are particularly sensitive to development. Plant or animal species which are endangered species, or candidate species, protected bird species under endangered species laws and regulations, plant protection laws and regulations, Fish and Game codes, or species of special concern listings and policies, or species recognised by national, state, or local environmental organisations. (18 Nov 1997) |
| species | A taxonomic category subordinate to a genus (or subgenus) and superior to a subspecies or variety, composed of individuals possessing common characters distinguishing them from other categories of individuals of the same taxonomic level. In taxonomic nomenclature, species are designated by the genus name followed by a Latin or Latinised adjective or noun. (18 Nov 1997) |
| species area curve | The curve on a graph produced when plotting the cumulative number of plant species found in a series of quadrats against the cumulative number or area of those quadrats, it is used to determine the number of quadrats sufficient to adequately survey the herbaceous understory. (09 Oct 1997) |
| species group | <zoology> The taxonomic categories species and subspecies. (09 Jan 1998) |
