		Changes in the distribution of ruderal flora and vegetation in the Orlické hory Mts.
		Ruderal vegetation of the territory studied is dominated by expansive and partly by invasive species.
		The changes in distribution of ruderal species are reflected by increasing number of their localities, their spread to higher altitudes and increasing abundance of their populations at particular localities.

		Much of this arid, desert-like area was disturbed by agricultural uses, and is subsequently covered with alternating patches of California juniper in undisturbed areas, and rubber rabbitbrush or weedy ruderal vegetation in the recently disturbed areas.
		In the event that fl locust poses a future threat to native vegetation at the site, seedlings should be uprooted and saplings should be cut flush to the ground and immediately treated with herbicide (i.e., glyphosate).
		Ruderal vegetation is present in areas that have been recently disturbed, including the 8-foot-wide clear strip adjacent pavement, in turnouts, and along driveways.

		Many of these garden flowers are what are called ruderals (many, out of their native habitat, are the weeds of the world).
		Ruderal plants rely on a strategy of getting theirs first through competition, flowering quickly, and quickly producing many, many seeds to out- reproduce their competition.
		Ruderal plant life cycles are based upon year- to -year strategies, with little or no long-term strategies (that is, ruderal plants are mostly annuals, or short-lived perennials or biennials).

		On topsoil, ruderal annuals are dominant in the first year and are replaced by short-lived perennials from the second year.
		On the ruderal landfill soil the early successional stages are less sharp and the perennial Solidago canadensis is able to dominate within one year after succession was initiated.
		The importantance of 'initial floristic composition', the role of substrate for community structure and the peculiarities of successional sequences on anthropogenic soils in the context of primary and secondary successions are discussed.

		There was an overall reduction in competitive species and an increase in ‘ruderal’ species typical of disturbed ground, perhaps an indication of management impacts on these wooded hedges.
		Mean proportion of Ruderal species found in hedge plots in England and Wales in tall grass and herb and lowland wooded in 1990 and 1998.
		A highly significant increase in the proportion of ruderal species was found in lowland wooded and a highly significant decrease for tall grass and herb.

	THE SHOW SO FAR: ruderal ecologies
		I am seeking solace in observing ruderal ecologies.
		I took my class to the local garbage dump today, where we saw broad and lanceolate leaved plantains (plantago), dock (rumex), bitter cress, crysanthemum leucanthemum and buttercup growing (and in fact thriving) in gravel soaked with toxic waste.
		Here are some Super 8 mm stills of the ruderal systems that existed between East and West Berlin, before the so-called 'fall of communism.' The images which I filmed in 1983, clearly show the European buzzards, hunting the hares on the green grass of the mine field.

		In ruderal habitats a variety of weeds serve as host plants including brome grasses, sweetclover, prickly lettuce, western ragweed, and sunflower.
		In ruderal habitats and cropland the Packard grasshopper may be a serious pest.
		Factors that appear to have made ruderal tracts more favorable for these species include the formation of better egg-laying sites of drift soil and south-facing slopes, and the introduction of succulent weeds and cereal crops that serve as reliable, abundant, and nutritious sources of food.

		While species with broad ecological and sociological amplitudes are found in city centers the ruderal vegetation is developed optimally at the ancient outskirts of the towns.
		The transitional state of the investigated cities is shown by the fact that nitrophilous skirt communities are remarkably frequent, while mediterranean ruderal communities of the alliance Hordeion leporini are relatively poorly represented.
		In central Europe north the Als, the spontaneous plant species of city walls are first of all ruderal plants, but woodland species, plants of Sedo-Scleranthetea and Festuco-Brometea appear too, whereas Aspenietea species except Asplenium ruta-muraria and Cymbalaria muralis are of less importance.

		A comparison of our species list with diagnostic species of modern syntaxa of ruderal vegetation gives evidence that some synanthropic plant species achieved their community-forming role only during the last millennium.
		Thus, we can assume that in ancient Kiev, several paleosyntaxa of ruderal vegetation were already well developed by the 10th, 11th, and 12th centuries, and these paleosyntaxa were similar in their ecological and phytosociological characteristics to the listed syntaxa of the present-day ruderal vegetation of Ukraine.

	Definitions
		This means that they have short-term strategies: they are short-lived, produce lots of seed or propagules, do not have any fungi or bacteria friends, nor produce their own chemicals, such as antibiotics to protect themselves from pathogens.
		They are usually also termed pioneer plants in their own plant community and/or they live in easy spots, such as along creeks and rivers, where there is lots of food and water.
		The only native plants that fit the ruderal definition are things like Evening Primrose (Oenothera hookeri), Horsetail (Equisetum spp.), Bulrush (Scirpus spp.), etc. These aren't even in the same league as the non-native ruderals, many of which have adapted to human disturbance and just follow in our wake (Bromus spp., Erodium spp., Lobularia sp.

		Upland areas likely to be affected by SMP activities are largely located on channel banks, modified floodplains, fields adjacent to streams, along access roads, and along levees upslope of salt and brackish marshes and freshwater wetlands.
		Sparse ruderal vegetation can occasionally also be found in channels on sediment benches and bars.

		A ruderal is a plant of wasteground, roadsides and similar, human-affected, open ground situations - and by extension, one can talk of "ruderal" habitats.
		On the other hand, many of the non-gill trunk-growing species last all year, or certainly for a good part of it, often different in their visible form, but nevertheless still visible.
		And as to 'ruderal' as a linguist by trade, I can't help adding that the word comes from New Latin 'ruderalis' from the Latin 'rudus' meaning 'rubble'.

		In contrast, 30% of all species and 50% of all germinants were exotic, ruderal forbs.
		Wind-dispersed annuals and perennials dominated litter samples whereas ruderal forbs and graminoids with limited dispersal dominated soil samples.
		Our results suggest that silvicultural thinning will enhance the establishment of ruderal, exotic species, but will contribute little to the regeneration from buried seed of the vast majority of forest understory plants.

		It is important to note that rivers, wind, glaciers, tides, waves and wildlife trampling (and burrowing), are all types of disturbance that have been occurring on earth for a very long time.

		Short-lived ruderal fields: predominantly habitats heavily disturbed by construction and storage operations; depending on how the operation is organized or on the time of construction, these habitats partly allow a chance for the development of later succession stages of vegetation to temporarily survive
		Urban vacant areas: small to moderately large vacant areas currently not officially used (agricultural maintenance land [construction expected], rubble fields etc.) or maintained; various seral stages often rotate within a small area, depending on substratum conditions, historical background and current wildlife exploitation
		Ruderal semi-dry meadows: mostly spacious reforestation areas with young poplars and other tree species on former sewage farms; very similar vegetation appears on covered rubbish dumps and non-reforested sewage farms

		Both reforestation and ruderalization will likely lead to a loss of biodiversity in the years ahead as important habitats and species niches are lost.

		Survival strategies of Silene tatarica (Caryophyllaceae) in riparian and ruderal habitats
		Certain morphological and anatomical structures of riparian plants might be important for their survival during the season when they are exposed to severe stress caused by flooding, burial, fluctuating temperatures, and drought.
		These rare characteristics were studied as related to their ecological consequences in a threatened plant, Silene tatarica (L.) Pers., in riparian and ruderal habitats.
