Influence of riparian buffer width on bird assemblages in western Oregon
Article Abstract:
Current forest practices in riparian areas in the Pacific Northwest focus on maintaining a habitat for terrestrial wildlife, but little is known about non-fish vertebrates' use of riparian buffers and how their width may affect species abundance. A new study assesses the relative value of riparian buffers to songbird abundances along headwater streams in the Oregon Coast Range. The study shows that higher species richness occurs in logged riparian areas compared to unlogged sites and reveals that loss of habitat may be mitigated for some, but not all, forest songbirds by retaining riparian buffers.

Diversity and abundance of landbirds in a northeastern industrial forest
Article Abstract:
Researchers investigated the abundance of migratory landbirds, and the number of different species of landbird, in a Maine industrial forest region containing nine types of habitat. The aims were to relate results to reports of declining landbird populations, and to suggest industrial forestry practices which would best maintain bird populations. The results revealed that young, regenerated forest areas had the most birds and the greatest diversity of species. Mature hardwood areas had the least number of birds, and along with clearcut areas, the least diversity of species.

Conifer release alternatives increase aspen forage quality in northwestern Ontario
Article Abstract:
Conifer release involves removing vegetation from the surroundings of conifers using herbicides, and it cuts down on browse availability and usage of treated locations by moose during a period of up to four years. The impact of release on forage quality has yet to be clarified, so a study of this has been carried out in northwestern Ontario. The results indicate that biomass availability of species of foreage plants that ungulates are known to use is a realistic method of predicting what the impact will be of treatments involving conifer release on forage for ungulates.
