### covering | cover:

Dense cover
* is important for foraging on insects and for nest cover
  - used for winter shelter and protection
* provides shelter from predators.

Ice cover
* appears to be the decisive factor in the distribution of most white whale stocks.
* is complete for about nine months of the year and is predominantly landfast ice
  - extensive in severe winters, but of only local importance in normal winters
* prevents further evaporation from the lake surface.

Integument
* are covering.
* elongate dorsally as the ovules develop.
* harden at the end of embryonic development to form the seed coat.
* is the skeleton.
* lack pigment.

Land cover
* can have direct impacts on the atmospheric system.
* describes the vegetation, water, natural surface, and construction on the land surface
  - what currently exists at a place on the earth's surface
* is also a primary determinant of land use and of land management activities
  - one of the several components of landscape
* is the physical state of the land surface
  - product of past land uses on the backdrop of the biophysical setting
  - vegetation or other kind of material that covers the land surface
* refers to vegetation and other materials that cover the surface of the Earth.

Natural cover
* includes dead water pools, boulders, bank-cover, aquatic vegetation, and log jams
  - such things as logs, trees, stumps, ravines, and hollows
* is managed by planting, pruning, thinning or clearing.
* means what type of natural hiding places for fish exist in the stream.

Pelt
* Most pelts are made from the hides of yak calves that have died.
* are most valuable in winter when the fur is thick to protect animals from cold
  - organic matter
  - the skins of animals with the fur attached

Plant cover
* benefits a river basin in a number of ways.
* helps control rangeland soil erosion.
* is also important to reduce soil erosion
  - non-existent over much of the dry desert
  - vital to keep loosestrife from re-invading

Row cover
* are excellent protection for young plants against all insects
  - sheets of non-woven polyester fibers which are draped over the plant row
* used early in the season can prevent infestation by cucumber beetles.

### covering | cover:

Slough
* Most sloughs have dingy or tea-colored water.
* appears in an array of yellow, grey, green, and brown colors.
* are bogs
  - broad shallow channels that contain flowing water
  - channels of free-flowing water in between the sawgrass marshes
  - large areas of thick gooey mud
  - slow moving water drainage
  - swamp
* is situated in south east England between West London and the Thames Valley
  - tissue that is granular and red
* provide a conduit for the input or export of organisms to Grizzly Bay.

### covering | cover:

Snow cover
* can act as a blanket and prevent safe ice from forming
  - adversely affect the strength of ice
  - also vary considerably from year to year
  - protect crops from extreme cold
* has a chilling effect on climate
  - dramatic effects on the structure and functioning of Arctic ecosystems in winter
* increases the development of Sclerotinia crown and stem rot during the winter.
* insulates plants from exposure to lethal and sub-lethal temperatures in winter.
* is adequate to protect fall seeded crops and forage
  - derived from climatology and is accounted for as a modification to the surface albedo
  - important for the salmon
  - more important than low temperatures in initiating dormancy
* provides important insulation and protection to hibernating animals.
* reflects a large amount of sunlight back into space.
* remains in the high mountain regions.
* tends to reduce maximum daytime temperatures.
