Flora and Fauna Survey
In December 2015 Council engaged Ecosure, an ecological consultant firm, to undertake a comprehensive flora and fauna survey of Council’s bushland areas including selected unmade road reserves.
The purpose of the survey, which replicated previous surveys, was to provide a snapshot of the current biodiversity values and condition assessment of Council’s major natural assets. The study area comprised all large bushland sites and 33 Unmade Road Reserves, all of which are Zoned E2 (Environmental Conservation) and managed by Mosman Council.
The report also compared new data with previous surveys to assess the progress made in the restoration of bushland areas under Council’s current Bushland Restoration Contract. The assessment of the Bushland Restoration Contract was reported to Council on 3 May 2016 (EP/34).
Council’s last comprehensive flora and fauna survey was completed in 2007.
The 2016 survey has highlighted that Council’s flora and fauna and ecological health of bushland sites continues to improve. This is testament to Council’s consistent work program aided by dedicated Bushcare volunteers. Some of the key findings and changes from the last survey include:
- There were 490 indigenous native plant species recorded (up from 454 in the 2007 survey)
- Two (previously unlisted) threatened plant communities were identified in five reserves
- An additional threatened fauna species, the Large-footed Myotis, a type of fishing bat was identified. This species was initially recorded as part of a Department of Primary Industries study in the species presence in Sydney Harbour after it was discovered in 2014. It is now officially recorded in the 2016 flora and fauna survey
- Confirmation of the presence of bandicoots
- Updated vegetation types to include all classification types commonly used within the industry
- An inventory of fauna habitat features for each site has also been provided. This provides an indication of which species are likely to occur and what habitat niches can be created on a site to improve biodiversity

As part of Council’s bushland management review in 2000 Council resolved to undertake a flora and fauna survey to assist in setting priorities and determining specifications for future bushland management. This flora and fauna survey was conducted over the summer of 2000/2001 by Oculus and Council received the final report which was reported to Council on the 12 June 2001. A part of the review process and MOSPLAN objective was to replicate this study in five years time to assess the effectiveness of the program and scheduled works.
The 2006/2007 Flora and Fauna Survey was completed by the ecological consultancy company Total Earth Care (TEC). The field survey was conducted from September 2006 to April 2007 and included a comprehensive flora survey and a late Spring and early Autumn nocturnal and diurnal fauna survey. Fauna was also noted when surveying each site for flora. Fauna census data from 2001 to 2006 was also utilised.
In total the survey involved 22 larger bushland sites containing, in most parts, remnant urban bushland and 84 road sites containing remnant urban bushland, weeds or landscaped gardens.
The purpose of the survey was three fold. The principal requirement was to create an updated and realistic inventory of what flora and fauna is currently present in the Mosman managed bushland areas. Surveys were terrestrial only and all sites were surveyed and weed and bushland percentage cover maps were produced. Secondly these results were used to compare the survey results of the flora and fauna survey produced by Oculus in 2001. The final purpose of the Flora and Fauna Survey 2006/2007 was to use this information to measure the performance of Council’s bushland regeneration contractors and determine whether or not they are meeting the objectives and contract specifications as outlined in Council’s Contract for Bushland Restoration 2001-2011.
Results form the Flora and Fauna Survey 2006/2007 indicate that current bushland management activities are achieving the desired outcomes in that weed percentage cover is reducing but more importantly native vegetation cover is increasing. If these are continued our bushland sites will eventually provide structured and sustainable native plant communities that will attract the local fauna to reside long-term.
