The Dynamic Landscape
Ecological strategy
This has been discussed in terms of the plant strategy models of Grime in Chapter 4.
These models, in essence, integrate some of the factors already discussed, with regard to growth rate, etc., and are very useful aids to plant selection. A rather demanding example of this can be found in Hodgson (1989). Strategy data on individual native species are provided in Grime et al. (1988). Hitchmough (1994) has speculated on the strategies of a number of exotic species.

Depending on the area to be sown, broadcast sowing can be undertaken by hand by a chest-mounted spinning disk, a wheel-mounted spinning disk spreader or tractor-mounted equivalent. For really large-scale …
As can be gathered from the section ‘Types of herbaceous plant communities: habitat stereotypes’, there is potentially an attractive naturalistic herbaceous vegetation for every site, no matter how wet or …
This characteristic derives from the combination of high tolerance of competition, longevity and low palatability to slugs as established plants. When dealing with very weedy sites or sites where management …
