Tasman Island invertebrates

​Application for Scientific Permit – Available for Public Comment

Public comment on the following application for a Scientific Research (Fauna) Permit is open until 1 April 2021

Applicant: Friends of Tasman Island

Species/Taxon: Invertebrates – mainly insects and spiders

Location: Tasman Island, Tasman National Park

Title of research: Invertebrate Survey of Tasman Island

Aim of project:
Survey and identification of invertebrates on Tasman Island and design of long-term invertebrate monitoring.

Justification:
Tasman Island is isolated from the Tasmanian mainland and only visited infrequently. Substantial weed reduction work has been performed by the Friends of Tasman Island (FoTI) and DPIPWE which has resulted in increases in native vegetation.
Systematic invertebrate surveys of Tasman Island were conducted by DPIW in 2005 as part of the Hamish Saunders Memorial Island Survey Program, prior to much of the revegetation and cat eradication. The only invertebrate records since then have been opportunistic by FoTI volunteers. Many groups of invertebrates (e.g. native wasps, beetles, moths) appear to be under-represented in the species records available on the Natural Values Atlas (NVA) or Atlas of Living Australia (ALA).
The proposed research would document some of these under-represented groups and provide a comparison with the 2005 survey, including changes due to increases in natural vegetation.
FoTI would like to establish a long-term monitoring program for Tasman Island. This research will provide a monitoring point and/or baseline for future evaluation of changes on Tasman Island and any management interventions.

Maximum likely numbers of individuals involved:
Exact numbers unknown. Effort: up to 50 trap-days of dry pitfall traps & 9 days of other activities by 2 people across all the vegetation types on the island.

Activities undertaken and methods:
Sweep netting of vegetation
Beating of vegetation on to beating sheet
Malaise trap
Dry pitfall traps for up to 8 hours
UV moth trap

Fate of animals:
All invertebrates collected will be photographed in situ and released

Likely impact on species involved (including any by-catch):
Minimal impacts are anticipated with no mortality and very limited interaction with researchers.
