1
Q
Biodiversity in the city
A
- Focus on bat, swift, sparrow, bee species, rare plants
- Species are dependent for hibernating, breeding, habitat etc. on human environment
- Threatened and protected species
- Indicative for varied environment
- Ecosystem services
- Lichens VS. air quality
1
Q
Half natural grasslands
A
- Herb-grass mixtures
- Roadsides, lawns, fallow land
- Comon species like buttercup & common sorrel
- Mowed twice per year, hay is removed.
2
Q
Herb-rich pioneer vegetations
A
- Arable land
- Pioneer vegetation like common poppy and cornflower, oats and barley
- Shortliving species
- Insect-rich
- Mowing, remove straw and plowing the soil
3
Q
Waterrelated vegetations
A
- Moist grasslands
- Edges ponds & waterways
- Ragged-robin, marsh orchid are indicator species
- Extensive mowing with removal of hay
- highest level of biodiversity
4
Q
Grasslands
A
- Specialist vegetations
- Greater yellow-rattle
- Half parasite
- Suppressing grass
- Specialist mowing
5
Q
New nature
A
- Small hills
- Limestone addition
- Nutrient poor
- Species rich
- Oxeye daisy
6
Q
Small terrain mowing machine
A
Used when the area is small with vulnerable vegetation and rare and indictace species.
7
Q
Big terrain machine
A
Used when the area is more large scale, three times per anum.
8
Q
Creating varied forest edges
A
- 5 to 10 meter strip that is mowed once per year
- Cut individual trees in the forest edge and let them fall into the grassland
- Lay trees in the opposite direction towards the forest
- Stems, branches and pruned shoots of shrubs can de piled up to create hiding and breeding places for small mammals.
9
Q
Sinus mowing
A
- Mowing three times per year
- Every mowing other parts are done, never the whole area
- Highest variation in vegetation structures on behalf of biodiversity
