Crataegus (/ k r ə ˈ t iː ɡ ə s /), commonly called hawthorn, quickthorn, thornapple, May-tree, whitethorn, or hawberry, is a genus of several hundred species of shrubs and trees in the family Rosaceae, native to temperate regions of the Northern Hemisphere in Europe, Asia, North Africa, and North America. C. monogyna is often planted in hedges and shelterbelts on farms and as an ornamental shrub or small tree in towns and cities and has been successfully used in revegetation and land reclamation of wastelands and mine spoils (Kluczynski, 1981; La Marca et al., 1998) as well as on polders in Holland (Peeters and Stuurman, 1981). Until recently I had a few hawthorn trees along the boundary with my neighbour, but we have chopped them right down to the base. It has been widely introduced, is commonly planted and has become naturalized in North America, southern Africa, Australia and New Zealand having been introduced to each sometime in the 1800s.

There are relatively few pests and pathogens of C. monogyna. Hawthorn Hollow’s programs are linked with the Next Generation Science Standards and Wisconsin’s Social Studies Standards. C. monogyna is found in lowland areas on many soils, and is often considered principally a forest understory species in its native range, though it also prefers moist to damp disturbed places such as wetlands and lake margins as well as and open forests. Wide dispersal of seed by birds cannot be controlled; therefore controlling the spread of privet requires the removal of seed trees and young seedlings before they produce seed. Native species disperse the newcomer plants. Williams PA; Buxton RP, 1986. However, in the seeds it is present as a compound called amygdalin built up from hydrogen cyanide, benzaldehyde and a sugar. Weed seeds often are dispersed by tillage and harvesting equipments. Detailed coverage of invasive species threatening livelihoods and the environment worldwide.

Larger plants can be cut to the ground and the stump treated with a 1:3 mixture of triclopyr (or glyphosate) and a light cooking oil as surfactant, and a 2-3% solution of triclopyr or glyphosate has been sprayed on the foliage for control, but this has not generally been reliable and is more likely to affect non-target species than are stump treatments (Alverson and Sigg, 2008). How does hawthorn dispersal its seeds? Acta Dendrobiologica, No. Another factor influencing hawthorn establishment could be seed dispersal, which can be linked to inundation events. 2007).

The genus Crataegus, part of the Rosaceae family (subfamily Maloideae), contains over 200 species, though some taxonomists divide these further and they may be over 1000 species depending on the descriptions followed. Invades: Highly invasive, commonly establishing in disturbed bushland Spread also occurs from contaminated produce and materials. Flora Europaea, Database of European Plants (ESFEDS). Nevertheless, in terms of the proportion of seeds at LSD, dispersal from hawthorn trees was consistently weaker in high forest cover landscapes than in low cover landscapes across sites (Wilcoxon test: W = 0, P = 0.050). In the wild, Smoke Trees propagate themselves through seed dispersal following the massive bloom cycle in the late spring/early summer. Interactions among non-native plants and birds.

Phenology, mode of reproduction, animal-mediated pollination and seed dispersal of hawthorn (Crataegus monogyna) was studied at three thorny shrubland sites - composed of hawthorn, Rosa micrantha, Rubus spp., Cornus sanguinea and Lonicera etrusca in a holm oak (Quercus ilex)/Arbutus unedo shrubland - in León province. Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds.Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. Relationships between fruit pests (larvae of Blastodacna hellerella Dup. In Australia, plants are severely attacked by the pear and cherry slug (Caliroa cerasi) in some years, which damages the foliage though this does not appear to harm the tree itself. return, aid in the rapid dispersal of the hawthorn seeds.

The principal purpose of the fruit is the protection and dispersal of the seed, though some seedless fruits have been developed. A European seed dispersal interaction relocated to New Zealand. A number of studies in both Europe, its native range, and in North America, part of its introduced range, have used this species to investigate fruit traits influencing intraspecific variation in seed dispersal. An extreme case is that of the Squirting Cucumber. When this separates from its stalk a hole remains at the point of junction.. Dordrecht, Netherlands: Kluwer Academic Publishers. Berries could roll down slopes and be spread by rivers and/or floodwaters, but this is not considered as significant as compared to birds and other animals in seed dispersal.

The stones and pips leave the animal's body via the droppings which may be some distance away from the parent plant. A seed is the mature reproductive body of angiosperms and gymnosperms. These plants are often found near places where birds have perched such as trees, poles and powerlines. Several varieties and forms have been proposed, and European species are described and defined by Christensen and Janjic (2006). Photo: Steve Attwood.
