Bird and small mammal use of short-rotation hybrid poplar plantations

Article Abstract:

Poplar plantations are an important source of biofuels and could become increasingly common across the US. A study designed to analyse the effect of replacing small grain fields or rowcrops with short-rotation poplar plantations on the abundance and diversity of mammals is presented. Some eight plantations in WI, SD and MN were included in the study, of which 6 were in forested areas. Small mammal and bird sampling at each site showed that there was little habitat loss for songbirds and small mammals, although abundance and diversity in forests and wildlands was higher than in the plantations.

A critical analysis on the use of indicator species in management

Article Abstract:

Management indicator and sensitive species (MIS) have been used widely in wildlife management but the assumption that the habitat quality for indicator species is also suitable for other species could be flawed. An examination of the habitat distributions of MIS in the Chequamegon National Forest of northern Wisconsin seeks to determine a positive association with other bird species. The study concludes that inconsistent patterns among most MIS questions their use as indicators for the well-being of other species.

Bird communities of early-successional burned and logged forest

Article Abstract:

A survey was conducted on early-successional forests created by fire or logging for birds and their habitat during the 1994 and 1995 breeding seasons. Findings showed that overall bird species richness and number of individuals were higher in burned forests than in logged forests. However, some species were more abundant in the logged forests than in the burned forests. The two types of forest had different densities of dead and live trees and size ranges of live trees.
