Edge-related nest predation in clearcut and groupcut stands

Article Abstract:

Group selection is a technique that provides an alternative to clearcutting, but it creates more edge per unit than clearcutting. Therefore, if edge-related increases in nest predation exist in forest compared to groupcuts, group selection may result in higher rates of edge-related nest predation than does clearcutting. To examine this concept, researchers deployed 80 artificial shrub nests baited with Zebra Finch eggs in edge areas and interior areas. They found that the probability of nest depredation is higher in edge areas than interior areas.

Predation on artificial nests in forested riparian buffer strips

Article Abstract:

A study of predation on artificial nest in a forested riparian buffer strip showed significantly higher incidences of predation compared to an intact commercial forestland. Predation in the buffer strip reached a rate of 30% compared to 15% in the intact forest. The increased predation is attributed to the number and diversity of predators that has gained access to the strip, composed mostly of forest species as opposed to the expected riparian species.

Productivity of early successional shrubland birds in clearcuts and groupcuts in an eastern deciduous forest

Article Abstract:

Research is presented concerning the impact which the even-aged management of forests has on the diversity and productivity of forest birds which live in mature forests. Clearcuts are compared with groupcuts.
