Barren vegetation describes an area of land where plant growth may be sparse, stunted, and/or contain limited biodiversity. Environmental conditions such as toxic or infertile soil, high winds, coastal salt-spray, and climatic conditions are often key factors in poor plant growth and development. Barren vegetation can be categorized depending ...
Regions with sparse vegetation and a low vegetation index are shown in tan. Based on measurements from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite. Areas where there is no data are gray. [1] Vegetation is an assemblage of plant species and the ground cover they provide. [2]
This is generally a problem encountered by species that utilize passive reproduction and possess low mobility, such as plankton, plants and sessile invertebrates. [6] For example, wind-pollinated plants would have a lower fitness in sparse populations due to the lower likelihood of pollen successfully landing on a conspecific.
White spruce (Picea glauca) is an example of a climax species in the northern forests of North America due to its ability to adapt to resource scarce, stable conditions, it dominates Northern forest ecosystem in the absence of a disturbance. [10] Other examples of climax species in old-growth forests: Canadian hemlock; Pacific silver fir; White fir
A rare species is a group of organisms that are very uncommon, scarce, or infrequently encountered. This designation may be applied to either a plant or animal taxon, and is distinct from the term endangered or threatened. Designation of a rare species may be made by an official body, such as a national government, state, or province.
The correlation between aridity and sparse population is complex and dynamic, varying by culture, era, and technologies; thus the use of the word desert can cause confusion. In English before the 20th century, desert was often used in the sense of "unpopulated area", without specific reference to aridity ; [ 2 ] but today the word is most often ...
In Britain, a variety of status categorisation schemes exist, for sites, species and habitats.These include, for species and habitats, Red Data Book threat categories, national rarity and scarcity assessments and Biodiversity Action Plan statuses, and for sites, statutory statuses such as the SSSI concept, and non-statutory statuses such as county wildlife sites.
Non-vascular plants , with their different evolutionary background, tend to have separate terminology. Although plant morphology (the external form) is integrated with plant anatomy (the internal form), the former became the basis of the taxonomic description of plants that exists today, due to the few tools required to observe.
