1.0 Introduction

The Association for Christian Education Inc. owns and operates the Rehoboth Christian College at 92 Kenwick

Road, Kenwick, within the City of Gosnells (Figure 1). A referral describing proposed extensions to the school

was submitted to the EPA under Part IV of the Environmental Protection Act 1986 (WA) due to the potential

impacts on flora and wetlands within the school boundary. Bulletin 1249 was issued by the EPA in March

2007 indicating that the assessment level for the project was ‘assessment on referral information’ (ARI).

Ministerial Statement 780 indicating that the project could proceed was published on 19 January 2009 by

the Office of the Environmental Protection Authority (OEPA).

Phase 1 of the extension works involved the:

development of 1.0 ha of land that was characterised as a conservation category wetland (CCW) that

includes 0.60 ha of the threatened ecological community (TEC) claypan wetlands

conservation management of 2.3 ha of two TECs in the remainder of the school lot, including:

full rehabilitation of 0.18 ha of TEC claypan wetlands

partial rehabilitation of 0.66 ha of TEC claypan wetlands

preparation of a series of management plans for wetland and drainage areas.

Rehoboth Christian College is still in the process of considering phase two of the development in the

triangular area to the bounded by Brixton Street, Wanaping Road and the wetland area.

Natural Area Consulting, a division of Natural Area Holdings Pty Ltd was commissioned by Rehoboth

Christian College on behalf of the proponent, Association for Christian Education Inc., to prepare this 2014

Annual Compliance Report. It will report on the project for the period 20 January 2013 to 19 January 2014,

when this report was submitted to the Office of the Environmental Protection Agency (OEPA). It will provide

information relating to compliance included within in the Ministerial Statement Audit Table along with those

developed for the Wetland Rehabilitation Plan, the Wetland Management Plan and Drainage and Nutrient

Management Plan. Supporting data in the form of monitoring and other reports will also be provided.



2.0 Current Status

The project has been implemented, with building works completed and management plans prepared and

currently being implemented. Implementation of the proposal commenced in February 2011, as it was

dependent on approval of the management plans by the OEPA, which occurred in November 2010 (Sands,

2012, personal communication; OEPA, 2010, personal communication).

Implementation of the wetland revegetation plan continues, with Natural Area Management and Services

(NAMS) being commissioned by BlueSands Environmental to carry out:

weed control works

rehabilitation works

vegetation monitoring

fauna monitoring.

NAMS undertook five weed control visits, the planting of 3511 native plants and vegetation monitoring

activities within the wetland area during 2013 (Natural Area Management and Services, 2013). Fauna

monitoring was limited to opportunistic sightings by NAMS and NAC personnel during site visits.

The second Annual Environmental Compliance Report was submitted to the OEPA in January 2013. Post

construction water quality monitoring was continued by Natural Area Consulting during 2013.



3.0 Compliance

The Association for Christian Education Inc. continues to comply with the conditions listed in

Ministerial Statement 780 and the approved management plans. Evidence of this will be provided in

the audit tables provided in Section 5.

3.1 Non-compliances and Non-conformances According to the Department of Environment and Conservation (2007), a non-compliance is a failure

to meet requirements specified within the Ministerial Statement, while a non-conformance is any

deviation from procedures, programs and/or management actions described in an environmental

management plan. No non-compliances or non-conformances were identified in the second (2013)

Annual Compliance Report (Natural Area Consulting, 2013).

There is one minor non-conformance for the January 2013 – January 2014 reporting period. During

the post-construction phase of the project, PoC5 indicates that fertiliser application will be subject to

soil analysis to avoid excessive fertiliser application and subsequent leaching into groundwater of

runoff into the wetland. Checks of the accounts payable records and discussions with grounds

personnel indicated that soil testing was not carried out during spring or early summer 2013 prior to

the application of fertiliser. While Nufarm carried out the testing on 15 January 2014, results were

not available prior to submission of this Annual Report and will be provided in the 2015 Annual

Compliance Report.

3.2 Complaints Register A complaints register has been prepared by Rehoboth Christian College and is kept at the front

office. The complaints register includes the following provisions:

date

complainant

contact details

nature of the complaint

response

date of response.

No complaints have been received since the register was prepared in 2012.



3.3 Compliance Statement This Annual Compliance Report provides verifiable evidence of compliance with required conditions

outlined in Ministerial Statement 780 and endorsed actions and commitments outlined in proponent

Management Plans.

4.0 Environmental Monitoring and Research

During the period 20 January 2013 – 19 January 2014, environmental monitoring and research

included ground and surface water monitoring, weed control and the monitoring of vegetation in

various quadrats and transects. The results of the weed control and vegetation monitoring activities

are provided in NAMS Wetland Rehabilitation Annual Report No. 3 (2013) included in Appendix 1,

and the flora and vegetation survey activities in Appendix 2. Fauna monitoring was limited to

incidental sightings by NAMS and NAC personnel during site visits.

Environmental monitoring of surface water within the conservation category wetland is required

during winter months, and groundwater monitoring is required quarterly. Post development water

quality monitoring requirements are outlined in the Wetland and Vegetation Management Plan

(BlueSands Environmental, 2010a). NAC continued post-development water surface and ground

water sampling activities during 2013.

4.1 Groundwater Monitoring Groundwater is monitored at three locations within the school grounds, namely bores RB1, RB2 and

RB3. Bore locations are provided in Figure 2. Analytical parameters for these locations are as follows:

groundwater level

pH

electrical conductivity (EC)

total suspended solids (TSS)

total phosphorous (TP)

total nitrogen (TN)

nitrate (NO3-)

ammonia/ammonium as nitrogen (NH3-N/NH4--N)

arsenic (As)

iron (Fe)

aluminium (Al)

acidity as calcium carbonate (CaCO3).

Pre-development groundwater monitoring was carried out in July 2010, with samples collected for a

small number of parameters. During development groundwater sampling was carried out in August

2011, with a broader range of parameters being tested. Samples were analysed by ARL, a NATA

registered laboratory. Results provided to NAC have been included in Table 1 to enable comparison

with post-construction activities.

Post-construction groundwater quality samples were collected by NAC during 2013 and analysed by

the NATA accredited ALS Group in Malaga, with results provided in Table 1. Samples were delivered

on the day of collection to ensure holding time requirements were met. Results are generally within

the ranges identified in the Drainage and Nutrient Management Plan (BlueSands Environmental,

2010). While arsenic levels are slightly higher than those recorded in 2012, they are still below the

95% level of protection (% species) trigger values for freshwater as recommended in the Fresh and

Marine Water Quality Guidelines (ANZECC and ARMCANZ, 2000). At present, it is unknown if this



result is due to natural variation or other factors. Nitrate levels have also increased slightly, and may

be the result of a wetter winter moving more nutrients through the superficial aquifer than in 2012.

Total phosphorous and nitrogen levels have declined from 2012 readings; this is seen as beneficial to

the wetland.

Note that changes to required sampling parameters occurred between the pre development, during

construction and the post construction phases as the various management plans were prepared and

approved. Table 1 shows results for all parameters that have been sampled for at any stage of the

project for completeness, with those documented within the approved management plans shown in

the top portion. Certificates of Analysis from ALS Global are provided in Appendix 3.

4.2 Surface Water Surface water within the conservation category wetland is monitored at 2 locations, as shown on Figure

2. Parameters include:

flow rate (m3/s) (quantity)

water level

pH

electrical conductivity (EC)

total suspended solids (TSS)

total phosphorous (TP)

total nitrogen (TN)

nitrate (NO3-)

ammonia/ammonium as nitrogen (NH3-N/NH4--N)

arsenic (As)

iron (Fe)

aluminium (Al)

acidity as calcium carbonate (CaCO3).

Surface water monitoring was carried out pre-development in August 2010, and during development in

September 2011. Samples were analysed by ARL, a NATA registered laboratory, and results are provided

in Table 2 to assist with comparison of results for the post construction period. Water levels were too

low during 2013 to allow the collection of representative samples by NAC. It was not possible to

determine the flow rate for the same reason. Results for the 2012 surface water monitoring activities

are provided in Table 2 for the purposes of consistency.

4.0 Flora Monitoring Refer to Section 8.1 of the Wetland and Rehabilitation Plan V3 (October, 2010) for further details on monitoring methodology and rationale.

4.1 Methodology

Baseline monitoring of Area 1 and 2 was undertaken on 16th April 2012 by NAMS. Three transects were established in the field, each being 30 linear meters (Figure 3); two transects were placed in Area 1 (partially degraded area) and one transect was placed in Area 2. Six 1m x 1m quadrats were installed at four meter intervals along each transect. The start and end point of each transect and all four corner posts of each quadrat are identified by permanent aluminium stakes with flagging tape. GPS coordinates were recorded of the start and end point of each transect as well as the centre point of each quadrat (Appendix 1). Subsequent monitoring visits were made on November 9th, 2012, April 5th, 2013 and November 21st, 2013

4.2 Monitoring Objectives

Objectives for the rehabilitation monitoring are provided in Table 4. Table 4: Objectives of the rehabilitation monitoring at Rehoboth rehabilitation site

Objective Species Sampling Type

1 70% Reduction (by area) in the distribution of weed species in the rehabilitation area after three years*

All weed species

Transects (30m long with 1m x 1m quadrats spaced 4m apart- 6 quadrats per transect)

2 80% survival rate of seedlings in degraded area (Area 2)

Planted seedlings


3 Natural regeneration of seedlings is occurring in the partially degraded areas after three years

Naturally regenerated native taxa


*It is unrealistic to achieve a 70% reduction in coverage from baseline data given that all three transects had an average baseline coverage below 2%. Weed control has aimed to maintain weed coverage below or equal to baseline monitoring.



4.3 Results

The results provided below refer to baseline monitoring results recorded on 16th April 2012, and follow-up monitoring data recorded on November 9th, 2012, April 5th, 2013 and November 21st, 2013

Objective 1: Weed Coverage Between November 2012 and November 2013 the coverage of weeds has decreased in Transects 1 and 2 and increased in Transect 3, however overall weed cover has increased across all three transects since baseline monitoring (Figure 4). At the time of monitoring Transect 3 had the highest weed coverage recorded at 74%. This high weed coverage was due to the presences of Lotus subbiflorus at high density in quadrats 1, 2, 3 and 6. Further weed control occurred after monitoring to target the Lotus subbiflorus and bring weed coverage at the site down to the objective coverage. A trend appears to be developing, showing that weed densities are lower in April and higher in November. This could be attributed to wet site conditions over winter supporting weed germination and growth, creating higher weed coverage in November.

Figure 4: Average percentage weed coverage

Objective 2: Seedling Survival (Area 2)

Seedling survival has averaged at 74.2% in November 2013, below the objective of 80%. Seedling deaths can be

attributed to harsh site conditions, including compacted clay soils and winter inundation. Even though the objective

survival rate was not reached, the stem count for Transect 3 has risen from 2 plants (0.3 per m2) to 16 plants (2.67

per m2). This is an 8 fold increase in the number of stems present.

There is evidence of some natural regeneration occurring in the partially degraded area (Area 1) particularly of

Acacia lasiocarpa var sedifolia along Transect 1. Many of the native plants recorded within quadrats along Transect 1

and 2 in baseline monitoring have grown and increased coverage within the quadrat (Figure 5). Evidence of existing

native growth can also be viewed in the photo monitoring records (Attachment 3).

Figure 5: Native species coverage (%) in Area 1

5.0 Lepidosperma rostratum Monitoring

No monitoring of the Lepidosperma rostratum community was scheduled to occur in 2013. The next population

survey is to occur in 2014.

6.0 Spring Flora Survey

To monitor the health and condition of the Conservation Area, NAMS has proposed to undertake a flora survey every 2 years to measure the cover and composition of native taxa, priority flora, presence of disease and cover and composition of weeds in the Conservation Area. The first flora survey was undertaken in August 2011 and reported in the Annual Works Report No. 1. The second flora survey was conducted in November 2013, results have been provided with this report. The final floristic survey is due to be undertaken in August 2015; results will be provided with the 2015 Annual Report.

7.0 Fauna Monitoring

No fauna monitoring was undertaken in 2013 as attempts to organise the monitoring in conjunction with the school teachers and students were unsuccessful. However, during the 2013 Flora monitoring notes were taken on the presence of fauna through direct sightings and brief examinations of tracks.

During the visit many invertebrate species were sighted, including various butterfly and spider species (Figure 6). The presence of Bandicoots (Isoodon obesulus) was indicated by dig marks (Figure 6); bandicoot diggings are triangular in shape while rabbit diggings are boxed at the end. Vocal calls of crows were heard and a Butcher bird (Cracticus sp) was seen. During the Flora Survey, several skink species were also noted.

8.0 Conclusion

Works in 2013 consisted primarily of weed control, revegetation planting and monitoring. Although the objective for

seedling survival has not been met, native species diversity and coverage has increased in all areas. This is further

supported by the flora survey which recorded an increase of 9 native species. Weed coverage has decreased in all

areas except Transect 3; further weed control was scheduled after the monitoring visit to deal with the high

abundance of weeds in this area.

Works in 2014 consist of monitoring only and will report on the ongoing success of rehabilitation activities.

1.0 Introduction

Natural Area Management & Services (NAMS) was appointed by Rehoboth Christian College in September

2011 to implement the Wetland and Vegetation Rehabilitation Plan (Blue Sands Environmental, 2010) which

pertains to Lot 107 Kenwick Road, Kenwick (the Study Area; Figure 1). The scope of works for the

implementation of the Plan includes undertaking the following over a period of 5 years:

1. Spring flora survey;

2. Weed control;

3. Seed collection;

4. Revegetation; and

5. Monitoring.

Revegetation works are focused on five areas within the Conservation Area (refer to Figure 1 and 2 in the

Wetland and Vegetation Rehabilitation Plan (Blue Sands Environmental, 2010).

1.1 Purpose of the Report The purpose of this report is to document the findings of the flora survey which was undertaken from the

26th November to the 37th November, 2013. This includes the following:

bushland condition;

weed mapping;

preparation of a comprehensive species list

1.2 Site Location The Study Area is located at Lot 107 Kenwick Road, Kenwick. The site is bound by Wanaping Road to the

north, Brixton Street to the West, Rehoboth Christian College oval to the south and residential property to

the east. GPS coordinates of the site are provided in Table 1.

2.0 Methodology

A Botanist from Natural Area Management & Services undertook field surveys in November 2013. The

bushland was traversed on foot in a pre-determined grid pattern. Each weed species was recorded and

mapped. Where weed infestations were larger than 1m2, the coverage was mapped using polygons and

assigned a density rating. For patches less than 1m2 a point was mapped and assigned a density rating.

Density ratings were:

Very Low 0% - 10% weed cover

Low 10% - 30% weed cover

Medium 30% - 70% weed cover

High 70% - 100% weed cover

Field mapping work was undertaken using a handheld GPS device with MobileMap software. At a minimum,

the following data attributes were collected:

Record Number: Unique identifier of the record

Family: Family name of weed

Scientific Name: Genus and species name of weed

Common Name: Common name of weed

Date: Date of survey

Area: Bushland name

Density: Level of infestation




3.0 Results

3.1 General Floristics A total of 68 taxa from 24 families were recorded; this included 25 weed species and 43 natives. The number

of weed species decreased from 31 in 2011 to 25 in 2013; native species decreased from 57 in 2011 to 43 in

2013. The most common weeds were grasses (Poaceae), and the most common natives were from the

family Cyperaceae. Several new species were recorded in 2013; of these 8 were native and 11 were weeds.

The new natives were present due to a combination of revegetation works and natural germination. The 11

new weed species recorded have most likely been introduced from seed blown in from adjacent properties

and dumping of green waste along the boundary closest to the school grounds.

Of the species recorded in 2011, 36 were not recorded in 2013; of these 20 were natives and 16 were

weeds. The difference in species presence could be due to seasonal changes in species composition; the

2011 survey was conducted in early August while the 2013 survey was conducted in late November. In the

August survey, standing water was still present on site and several annual species were just coming into

flower. In comparison, there was no standing water on site in the November survey and it was past the

flowering time for the most of the annual species. Weed control contract works may also have resulted in

certain species no longer being present on site.

The complete flora list is provided in Attachment 1 with images of selected species provided in Attachment

2.

3.2 Bushland Condition Vegetation condition was assessed using the Keighery Scale of Bushland Condition (Department of

Environmental Protection, 2000) which assesses the presence and absence of key structural layers

(Attachment 3). A visual inspection of the site was made and condition rating marked on an aerial

photograph, with occasional points marked by GPS to pinpoint smaller but significant areas.

Most of the site was classified as Good, with basic vegetation structure significantly altered through

noticeable disturbances (Figure 1). An area in the centre of the reserve is classified as very good with an

altered vegetation structure showing signs of disturbance. A Degraded area is present leading from a private

residence (north eastern side of the reserve) into the centre of the reserve. This area was dominated with

the weed species Lotus subbiflorus and Lythrum hyssopifolia. Two other small areas were categorised as

degraded, one adjacent to Wanaping Rd and a small section in the south of the wetland. Two

sections were categorised as completely degraded; one adjacent to the school oval and one in the north east

corner of the site. These areas were predominated by weeds with very little native vegetation present.

Green waste was also present in the completely degraded area adjacent to the school.

3.3 Weeds

A total of 25 weed species from 12 families were identified across the reserve. The presence and location of

the species is provided in Figures 2-7. Of these species, 10 species were present at a very low density (0-

10%); 9 species were recorded as high density (70%-100%). Grasses were the most common weeds although

Lotus subbiflorus and Lythrum hyssopifolia were also recorded at high density. 11 of the 25 weed species

recorded were not found in the initial 2011 survey; conversely 16 weed species recorded in 2011 were not

found in 2013.




4.0 Conclusion

The majority of the site is in Good to Very Good condition with only a few sections of Degraded to

Completely Degraded vegetation. The diversity of native species has increased by 9 species; however

additional species are likely to be represented at the site in the form of annuals.

Weed density and presence appear to be highest in areas adjacent to the road, private properties and the

school grounds. Dense infestations of weeds were noted outside the site boundary along Wanaping Road

and the western boundary; these weeds provide a source of seed to reinfest areas of the wetland.

A final flora monitoring event will be conducted in spring 2015. Additional information on species

composition and presence can be found in the 2013 Annual Report in the form of transect monitoring.

Transects were established in autumn 2012 and are scheduled to be monitored biannually until November

2015; monitoring has already occurred in April and November 2012 and April and November 2013.

Attachment 3: Keighley Scale of Bushland Condition

From Bush Forever Vol 2, Department of Environmental Protection (2000)

Category Description

1

Pristine

Pristine or nearly so, no obvious signs of disturbance.

2

Excellent

Vegetation structure intact, disturbance affecting individual species and

weeds are non-aggressive species.

3

Very Good

Vegetation structure altered obvious signs of disturbance. For example,

disturbance to vegetation structure caused by repeated fires, the

presence of some more aggressive weeds, dieback, logging and grazing.

4

Good

Vegetation structure significantly altered by very obvious signs of

multiple disturbances. Retains basic vegetation structure or ability to

regenerate it. For example, disturbance to vegetation structure caused

by very frequent fires, the presence of some very aggressive weeds at

high density, partial clearing, dieback and grazing.

5

Degraded

Basic vegetation structure severely impacted by disturbance. Scope for

regeneration but not to a state approaching good condition without

intensive management. For example, disturbance to vegetation structure

caused by very frequent fires, the presence of very aggressive weeds,

partial clearing, dieback and grazing.

6

Completely Degraded

The structure of the vegetation is no longer intact and the area is

completely or almost completely without native species. These areas are

often described as 'parkland cleared' with the flora comprising weed or

crop species with isolated native trees or shrubs.

General Comments

The analytical procedures used by the Environmental Division have been developed from established internationally recognized procedures such as those published by the USEPA, APHA, AS and NEPM. In house

developed procedures are employed in the absence of documented standards or by client request.

Where moisture determination has been performed, results are reported on a dry weight basis.

Where a reported less than (<) result is higher than the LOR, this may be due to primary sample extract/digestate dilution and/or insufficient sample for analysis.

Where the LOR of a reported result differs from standard LOR, this may be due to high moisture content, insufficient sample (reduced weight employed) or matrix interference.

When sampling time information is not provided by the client, sampling dates are shown without a time component. In these instances, the time component has been assumed by the laboratory for processing purposes.

CAS Number = CAS registry number from database maintained by Chemical Abstracts Services. The Chemical Abstracts Service is a division of the American Chemical Society.
