Windbreaks, Hedgerows, Woodland Corridors
ثبت نشده
چکیده
The concentration of animals in hedgerows also attracts predators from the surroundings 43’ (Fig. 6.10), just as hunters are attracted to wooded strips.299 Where large woods are scarce, certain owls and other predators require two or more smaller woods for their home range. So in a corridor connecting the woods, not much escapes the eyes and silent wing-beat of an owl. Nevertheless, compared with forest edges (chapter 3), predation rates in hedgerows are poorly documented.‘588*‘538~158g Clearly, more study of these conspicuous lines of source-and-sink activity is warranted.

Species Richness and Productive Forest Management 1
There are many reasons to preserve the biological diversity of the earth, and perhaps the most compelling is the insurance that it provides for the uncertain times ahead. The responsibility for maintaining this biodiversity falls particularly heavily on the custodians of the tropical forests, where species richness is highest. How can these forests provide for the immediate needs of local inhab...

متن کاملNatural Windbreaks Sustain Bird Diversity in a Tea-Dominated Landscape
Windbreaks often form networks of forest habitats that improve connectivity and thus conserve biodiversity, but little is known of such effects in the tropics. We determined bird species richness and community composition in windbreaks composed of remnant native vegetation amongst tea plantations (natural windbreaks), and compared it with the surrounding primary forests. Fifty-one, ten-minute p...
متن کاملEnvironmental risk factors associated with bovine tuberculosis among cattle in high-risk areas.
Our research shows that environmental features are important predictors of bovine tuberculosis (bTB) in British cattle herds in high-prevalence regions. Data from 503 case and 808 control farms included in the randomized badger culling trial (RBCT) were analysed. bTB risk increased in larger herds and on farms with greater areas of maize, deciduous woodland and marsh, whereas a higher percentag...
