Ecological Thinning Trial - Bird Monitoring 2020/22
Tender ID: 425166
Tender Details
Tender Description
The NSW National Parks and Wildlife Service (NPWS) is undertaking an ecological thinning trial in 400ha of Murray Valley National Park. This trial will gauge the effectiveness of ecological thinning as a way of promoting biodiversity in areas of river red gum high stem density areas.
Recent scientific studies have described a decline in the health of river red gum forests. Given ongoing river regulation and the likelihood of future droughts resulting from climate change, NPWS has worked with the Science Division to compose an experimental design and monitoring plan that seeks to determine whether reducing tree density leads to improved ecological health and biodiversity.
Reduced density is likely to mean more access to water, more mature hollow bearing trees which provide habitat and other valuable resources, and more wood debris for native animals and plants. It’s also expected to prevent further decline in the condition of the red gum canopy.
The operational phase of this project involved the thinning of 400 hectares of Murray Valley National Park. This contract relates to the ongoing monitoring program which will determine the effectiveness of thinning in achieving the project’s aims.
This part of the monitoring program requires the measurement of the abundance and frequency of use by woodland bird species at all 22 ecological thinning sites within Murray Valley National Park for two consecutive years.
