Excerpt from quote for monitoring from Alison Rowell Block 3, Section 22 Barton, ACT: • 5-year monitoring event for Golden Sun Moth • Condition assessment of Natural Temperate Grassland I attach my quote for monitoring and assessment of the Natural Temperate Grassland and Golden Sun Moth for the above site, as requested by Department of Finance & Deregulation (Finance), and as prescribed in the Maintenance Plan for the site prepared by PB Australia in 2007. The project will be supervised by Alison Rowell (targeted curriculum vitae attached), who will undertake the vegetation assessments and some of the GSM survey, and prepare the report. Subconsultants Dr Will Osborne, Mr Tom O’Sullivan and will be involved in marking of moths and statistical analysis. 1. Background The site contains a population of the Golden Sun Moth (GSM), which is listed as Critically Endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999, and Endangered under the ACT Nature Conservation Act 1980. GSM habitat on the site is ‘Natural Temperate Grassland of the Southern Tablelands of NSW and the Australian Capital Territory’ which is listed as an endangered community under the EPBC Act 1999 and the Nature Conservation Act 1980. The aim of the Maintenance Plan for this site is to ‘conserve native plant diversity while maintaining the structure and species composition thought to be favourable to the survival of the Golden Sun Moth’. The success of the Plan is to be gauged by regular monitoring of plant diversity, vegetation structure and the GSM population. 2. Scope Finance now requires: 1. an NTG condition assessment of Block 3, Section 22 Barton that maps the extent and condition of vegetation associations on the site and compares the results with the vegetation mapping conducted in 2007. The condition assessment is to assess and comment on the composition of native flora species, status of exotic weeds, the effectiveness of weed control and biomass management. 2. a 5 yearly monitoring event for the GSM population on Block 3/Block7, Section 22 Barton using personnel experienced in the use of the nested sampling structure that is referred to in the Natural Temperate Grassland Maintenance Plan. 3. Tasks and methods 3.1 Natural Temperate Grassland assessment • all plant species on the subject site will be recorded on the cumulative species list, and the results will be compared with previous assessments to measure changes in species richness and site condition over time • vegetation associations across the site will be mapped using the categories defined in the NTG Maintenance Plan • two step-point transects will be measured in November/December and the results compared to previous survey results Excerpt from quote for monitoring from Alison Rowell • plant cover and species diversity will be measured in November/December in a 20 x 20 m quadrat and compared to previous survey results. A survey for GSM pupal cases will be undertaken at the same time • any damage to vegetation on the site will be documented • the status of exotic weeds across the site and the effectiveness of weed control measures to reduce exotic weed cover and manage biomass will be assessed, and recommendations made • a photographic record will be made from the points indicated in Figure 4.2 of the NTG Maintenance Plan to give a general indication of vegetation structure on various parts of the subject site. 3.2 Golden Sun Moth population estimate A mark-recapture survey using a nested structure method will be used for the population estimate. There will be four to five primary sampling sessions (depending on the length of the flying season), each covering two days and with a break of six to eight days between primary sessions. The population experiences mortality (and potentially immigration) between primary sessions, allowing application of open population models. In each primary session there will be four one-hour mark-recapture sampling sessions, undertaken between 1030 and 1330 hours (i.e. two per day). This secondary level of sampling provides a short mark- recapture study within each primary session. Closed population models are used at this stage to estimate the animal abundance at each primary session. Observational surveys of the site will be undertaken weekly from late October to determine the beginning of the flying period. The site will be marked into 9 sections using flagging tape on the boundary fences, so that locations of captures can be recorded. Moths will be captured with a standard butterfly net. They will be removed from the net by a qualified and experienced ecologist, and marked on the hindwing with a fast-drying pen. Marked moths will be put in cloth-covered mesh holding cages and released at the end of each one hour survey. Analysis will be carried out using the software package MARK, which allows the estimation of total population size of closed and open populations, and provides estimates of daily survival rates and recapture probabilities. 4. Report A draft report with vegetation assessments and GSM population estimate will be provided by 14 January 2012, with a final report incorporating Finance’s comments by 14 February 2012. Excerpt from quote for monitoring from Alison Rowell CURRICULUM VITAE for Alison Rowell, Project Manager Biologist and Environmental Consultant Registered Business Name in the ACT: ABN: Ph : Email: Alison Rowell is a self-employed consultant, with 28 years' experience in surveys and studies of flora and fauna, specialising in survey, mapping and management of threatened native species and communities. Most of her recent work has been in woodlands and grasslands in south-eastern NSW and the ACT. She has carried out many surveys of the Golden Sun Moth (GSM) and its habitat, assessing the size and significance of populations and habitat, including qualitative and quantitative vegetation studies. Sites assessed vary from less than one hectare to larger than 100 hectares. GSM Survey methods used include walked transect and fixed point surveys for flying males, pupal case surveys, mark-release- recapture surveys, and broad and fine-scale habitat measurement. Alison undertook a mark-release-recapture study at Block 3 Section 22 Barton in 2006. Over 400 male moths were netted and numbered and the total population estimated. She prepared an impact assessment of the development proposed for part of this block and wrote a management plan for the GSM habitat in 2007. Her clients for recent GSM and Natural Temperate Grassland projects include ACT Plannning and Land Authority, National Capital Authority, ACT Territory and Municipal Services, Department of Defence, Department of Finance, Canberra Airport, SMEC, AECOM, ERM, URS, and Eco Logical.
