| If conditions are favorable, this step can be realized one or two years after the planting of pioneer species. |
|
| Ngar said authorities in the past introduced pioneer species such as acacias and eucalypts that adapted quickly to badly eroded areas on barren land. |
|
| High severity fire removed all bryophytes and only pioneer species were present 2 years later. |
|
| Alders are pioneer species that occur in areas that are reverting back to forest. |
|
| It behaves as a pioneer species and is found in degraded scrublands and forests margins. |
|
| To the south, along County Road 2 the vegetation is a mixture of shrubs and pioneer species of Trembling Aspen and White Birch. |
|
| Create a model that illustrates various stages of succession from pioneer species to a climax community. |
|
| They are pioneer species, preceding and preparing the way for other commercially harvested trees. |
|
| Quick starters' are preferable for this and most of these are ecological pioneer species, rather than members of climax communities. |
|
| They are a pioneer species – they chased the retreating ice northwards after the last great glaciation and are our oldest species. |
|
| By using a pioneer species such as poplar, the forest cover develops more rapidly. |
|
| Typically it is the pioneer species that grow back on clearcuts. |
|
| Rotting seaweed, brought in by storm waves adds nutrients to allow pioneer species to colonize the dune. |
|
| These pioneer species are marram grass, sea wort grass and other sea grasses in the United Kingdom. |
|
| Lichens are pioneer species, among the first living things to grow on bare rock or areas denuded of life by a disaster. |
|
| Our kapok, a pioneer species, is the tallest tree in the biome. |
|
| At one extreme are fast-growing pioneer species such as balsa or cecropia. |
|
| Early pioneer species, like sideoats grama and green sprangletop, began sprouting, enriching the soil and providing a bit of shade for later species, like Indiangrass and big bluestem. |
|
| We should concentrate on the implementation of pioneer species in cities, but that practice is road blocked by the conventional pestfree street tree lists of Urban Forestry departments. |
|
| The change may be slow and difficult to perceive over short periods of time, such as in the establishment of pioneer species such as mosses and lichens in a mined-over area, or it may be rapid as in the case of a forest fire. |
|
|
|
| The nominated site is interesting in that endemic species are the principal pioneer species in the process of colonisation, re-colonisation and ecological succession on both the natural areas of lava and the abandoned fields. |
|
| This sun-loving pioneer species, Salix bebbiana, thrives in moist soil conditions, but can also handle the heavy pounding of small feet on school grounds. |
|
| Thus, when the mean interval between forest fires is shorter than the pioneer species longevity, the landscape will be dominated by even-aged stands and few changes will occur in the canopy. |
|
| Thus if fire frequency is high, the landscape will be dominated by pioneer species, principally intolerant hardwoods, whereas as fires become less frequent, later successional conifers become more abundant. |
|
| Such cuts promote the growth of trembling aspen and other pioneer species, which are not very shade tolerant, to the detriment of species in the original stand. |
|
| This is therefore a pioneer species that colonizes depleted environments. |
|
| They are regarded as pioneer species, rapidly colonising open ground especially in secondary successional sequences following a disturbance or fire. |
