Steppeland Thematic Catalogue
Bijlmerweide is a natural and recreation area near the highly populated municipality of Amsterdam SouthEast. Here a group of volunteers belonging to a local nature association work together with the parks department of the city council to maintain and enable natural diversity and create some flower rich grasslands. Therefor, they participate in the regular mowing and removing of the vegetation by hand, of a few little grasslands in the area, and an inventarisation is made of the plants to document the effect of the treatment to the diversity of the plants growing on these lots.
Actually, the group “workers of the day” is seen in the background, crossing the bridge to the adjacent grassland area where the mowed vegetation still has to be removed.
Biodiversity and Conservation
Grasslands dominated by unsown wild-plant communities (“unimproved grasslands”) can be called either natural or ‘semi-natural’ habitats. The majority of grasslands in temperate climates are ‘semi-natural’. Although their plant communities are natural, their maintenance depends upon anthropogenic activities such as low-intensity farming, which maintains these grasslands through grazing and cutting regimes. These grasslands contain many species of wild plants – grasses, sedges, rushes and herbs – 25 or more speerican prairie grasslands or lowland wildflower meadows in the UK are now rare and their associated wild flora equally threatened. Associated with the wild-plant diversity of the “unimproved” grasslands is usually a rich invertebrate fauna; also there are many species of birds that are grassland “specialists”, such as the snipe and the Great Bustard. Agriculturally improved grasslands, which dominate modern intensive agricultural landscapes, are usually poor in wild plant species due to the original diversity of plants having been destroyed by cultivation, the original wild-plant communities having been replaced by sown monocultures of cultivated varieties of grasses and clovers, such as Perennial ryegrass and White Clover (Source: Wikipedia )
