摘要

Context

Working lands with forest plantations are widespread. To sustain biodiversity in these landscapes there is a need to understand how species respond to patterns such as the amount and configuration of remnant vegetation.

Objectives

We examine how the occurrence and reporting rate of bird species are shaped by landscape composition and configuration in working lands with extensive forest plantations in south-eastern Australia.

Methods

We used a whole-of-landscape study design, surveying birds in 36 landscapes (each a circle 1 km in diameter) with blue gum (Eucalyptus globulus) plantations. Landscapes varied in the proportion (0–72%) and arrangement of remnant vegetation. Birds were surveyed four times (8 sites per landscape) at a total of 288 sites. We modelled responses of bird species as a function of remnant vegetation amount and configuration, and the diversity of landscape elements.

Results

We detected 107 bird species and quantified how landscape elements influenced birds at three levels: sites within landscapes, the landscape (1 km diameter circle) and the extended landscape (3 km diameter circle). Analyses focused on 26 species observed at ≥ 10% of sites. Site-level analyses revealed 12 species were more likely to occur in remnants than plantations. The amount of remnant vegetation was positively correlated with four species at the landscape-level and five species at the extended landscape. Well-connected remnant patches positively influenced five species at the landscape-level and three species at the extended landscape. The diversity of landscape elements positively influenced two species at the landscape-level and two species at the extended landscape. Some bird species were associated with landscape elements at each level, others at only one or none.

Conclusions

Bird distributions are linked to the presence, amount and configuration of remnant vegetation within forestry landscapes. We recommend maintaining and increasing the extent and connectivity of remnant vegetation to support native birds.
