Executive Summary 
 
Byron Shire Council Roadside Vegetation Management Plan_V5
1944-1001 
v
 
 
 
This Roadside Vegetation Management Plan (RVMP or the Plan) has been prepared for Byron Local 
Government Area (LGA).  The aims of developing this RVMP are to: 
(a)
 
Protect significant conservation values, including threatened species and Endangered Ecological 
Communities (EECs). 
(b)
 
Balance ecological conservation with the necessities of roadside vegetation management. 
(c)
 
Outline the preferred management techniques for roadside vegetation within the project area. 
(d)
 
Improve Council’s capacity to protect, restore and minimise damage to significant roadside vegetation 
by promoting improved management practices. 
 
This project consists of three components: 
1. 
Production of the RVMP report. 
2. 
Production of a field booklet that includes maps and information on the maintenance activities for the 
conservation categories. 
3. 
Training for relevant roadside vegetation management staff and contractors on the use of the plan 
and booklet. 
 
Development of this RVMP was based around analysis of data collected in the Byron Shire Roadside 
Vegetation Survey (the Survey) across Byron LGA conducted in 2011/ 2012.  This was incorporated with 
existing data from vegetation community mapping, wildlife corridor mapping, threatened species records and 
Council’s Chemical Sensitive Register records.  The main product of this analysis was the categorisation of 
roadside vegetation into high, medium or low vegetation quality.   
 
The Survey collected data from 860 km of road reserve.  The Survey recorded 206 native plant species and 
79 exotic plant species.  Results of the data analysis identified that high quality vegetation occurs along 
12.5% of the roadsides surveyed.  Medium quality vegetation occupies 52.6% of roadsides and low quality 
vegetation occupies the remaining 34.9%.  There were 2,708 locations identified in the Survey that support 
threatened flora species listed under state and federal threatened species legislation and Rare or Threatened 
Australian Plants (RoTAP) species.  Four different EECs were also identified at 36 locations. 
 
This RVMP provides specific management actions for each vegetation quality category and for an additional 
category of special management areas that includes cultural heritage and community values.  These actions 
guide vegetation maintenance staff and contractors on the appropriate methods to undertake roadside 
vegetation management while protecting areas of High Quality Roadside (HQR) vegetation, threatened 
species and EECs along the roadsides of Byron LGA.  Recommendations for control of weeds and protocols 
for machinery hygiene are also discussed as weeds are a significant threat to the conservation values of 
roadside vegetation in Byron LGA.  Over 80% of the roadsides surveyed have over 80% exotic plant cover.   
 
Monitoring and evaluation guidance is provided along with an adaptive management strategy for future 
revision of the Plan so that newly available information and priorities can be incorporated, thereby 
strengthening future management protocols for high quality vegetation in Byron LGA.

Background 
Byron Shire Council’s (BSC) Byron Biodiversity Conservation Strategy (2004) identified the preparation of a 
Roadside Vegetation Management Plan (RVMP) as a high priority.  BSC received funding from the NSW 
Environmental Trust to complete a comprehensive roadside survey which was used to inform the 
development of the RVMP.  The project is overseen by a steering committee consisting of representatives 
from various divisions in Council with responsibilities for the management of roadside vegetation, 
infrastructure and the natural environment. 
 
BSC adopted a Rural Road and Roadside Land Management Plan (RRRLMP) at their meeting of 28 August 
2011 (Resolution No.  11-691).  The RRRLMP focuses on the construction and maintenance of roads and 
doesn’t provide a framework for best practice management of roadside vegetation.  This presents a 
significant threat to biodiversity through the potential mismanagement, spread of weeds and direct damage to 
high quality roadside (HQR) vegetation, including threatened species and Endangered Ecological 
Communities (EECs).  This project aims to ensure use of appropriate roadside vegetation management 
techniques. 
 
The Byron Shire Roadside Vegetation Survey (the Survey) was conducted in 2011/ 2012 along approximately 
860 km of rural roadsides by Environmental Training and Employment (EnviTE).  The Survey (EnviTE 2012) 
will form Part B of this project.  The RVMP has been developed incorporating the results of the Survey and is 
Part A of the project.   
 
This Plan does not include urban roads, and only applies to rural roads within Byron LGA with a speed limit of 
>60 km/h.  The Pacific Highway and Bangalow Road west of Bangalow are also not covered by this Plan, as 
these roads are managed by the Roads and Maritime Services.
