1
Q
Improve the quality of current sites (better)
A
- SSSIs under managed
- Lawton suggests increasing investments to manage current habitats
- Good management leads to increased wildlife benefits e.g the population of large blue butterflies are less likely to go instinct and produce up to 100 times more emigrants
- Less new habitats will have to be created
- Enhanced ecosystem services
2
Q
Increasing the size of current habitats (bigger)
A
- Lawton suggests bigger sites are more preferable than smaller because they contain more species
- Great geological diversity
- Easier to restore and promote more natural processes
- Important when choosing sites to enlarge as some species require ecotones
- Ecotones can sometimes be squeezed out as management hardens - one approach is to soften these to create a more gradual transition
- Less direct management, less cost
3
Q
Create new sites (more)
A
- Lawson suggests creating more smaller sites as part of ‘stepping stone’ sites
- Increase connectivity
- Considerable conservation benefits for poor dispersing species (e.g. marsh fritillary)
4
Q
Enhance connection between wildlife sites (joined)
A
- Connections made through stepping stone habitats and linear features features such as canals, rivers, railway embankments and hedges
- Reduces risk of regional extinction in meta-populations
- Enhance the functioning of natural processes
