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. from July to August). I usually take a mouthful of hawthorn fruit and spit out the seeds. Once established, C. monogyna can withstand moderate drought. Possum seed dispersal may also create a conservation risk by spreading invasive weed species. Many attempts to control or remove privet have failed because of its ability to regenerate vigorously from root and stem suckers. http://www.ars-grin.gov/cgi-bin/npgs/html/tax_search.pl, USDA-NRCS, 2007. Figure 7. Spring 1999. Franco, Crataegus laciniata sensu Willk., non Ucria, Crataegus oxyacantha L., nom. One nature preserve in Willamette Valley, Oregon, USA, has had to be abandoned because C. monogyna has invaded and there are not adequate resources to control it (Alverson and Sigg, 2008), and there is also a specific threat to the Garry Oak ecosystem of British Columbia, Canada. Although germination of the seed is facilitated by passing through a bird’s digestive tract, this is not absolutely necessary for the process to occur! Then when the animal travels the seeds might fall off the animal and land in a new place. subsp.

Fertilized flowers produce small (1.25 cm) red berries called pomes or haws which contain a single seed – hence the common name single-seed hawthorn. Further invasion and spread of this species is to be expected especially in North America, and further introduction should be prevented.

Cherry Blackberry Hawthorn The spines deter grazing animals, and the plant is regarded as an impenetrable barrier to grazing. This species reproduces mainly by seed, which are commonly dispersed by fruit-eating (i.e. Ekspert. However, where invasive, it displaces native plants, and dense thickets alter the structure of the forest understory and can make the movement of large animals difficult. Hawthorn's thickets are shelters for many birds and little mammals, therefore, they are important for nature protection purposes, especially on agricultural or urbanized grounds.
