Fraxinus excelsior, known as the ash, or European ash or common ash to distinguish it from other types of ash, is a flowering plant species in the olive family Oleaceae. It is native throughout mainland Europe [ 2 ] east to the Caucasus and Alborz mountains, and west to Great Britain and Ireland , the latter determining its western boundary.
In order to reduce the potential harms of the sawtooth oak, researchers and scientists are advising to remove tree saplings and remove the plant species altogether from reclamation species lists. Due to their preference for well-drained acid soils, Quercus acutissima is able to thrive and survive in various harsh locations. [ 6 ]
Quercus coccinea, the scarlet oak, is a deciduous tree in the red oak section Lobatae of the genus Quercus, in the family Fagaceae. It is primarily distributed in the central and eastern United States. It occurs on dry, sandy, usually acidic soil. It is often an important canopy species in oak–heath forests.
European ash in flower Narrow-leafed ash (Fraxinus angustifolia) shoot with leaves. Fraxinus (/ ˈ f r æ k s ɪ n ə s /), commonly called ash, is a genus of plants in the olive and lilac family, Oleaceae, [4] and comprises 45–65 species of usually medium-to-large trees, most of which are deciduous trees, although some subtropical species are evergreen trees.
Seedling development is typically good in old fields with well-drained loamy soils. Acorn supply is one of the principal determinants of the amount of natural cherrybark oak reproduction. Other factors include microclimate, soil properties, and stand variables. Seedling development is related to overhead release, with large openings needed.
Example: Hazel-ash coppice with hazel cut at 7 years and ash in the same area cut at 21 years (every third cut, all stools in the cant are cut). But note that under coppice with standards (for instance oak standards over hazel) the oak was cut under a much longer cycle. With hazel-ash under oak standards you now have 3 cycles superimposed.
In the northern part of its range, Quercus velutina is a relatively small tree, reaching a height of 20–25 metres (66–82 feet) and a diameter of 90 centimetres (35 inches), but it grows larger in the south and center of its range, where heights of up to 42 m (138 ft) are known.
Quercus myrtifolia, the myrtle oak, [3] is a North American species of oak. It is native to the southeastern United States (Mississippi, Alabama, Florida, Georgia, South Carolina). It is often found in coastal areas on sandy soils. [4] It is an evergreen tree that can reach 12 meters (39 feet) tall, also appearing as a shrub in drier sites.
