Onkaparinga River National Park Pest Prioritisation Report June 2009

A partnership project

Adelaide and Mount Lofty Ranges Natural Resources Management Board

and

The Department for Environment and Heritage

Statement of Plan

A partnership between the Adelaide and Mount Lofty Ranges Natural Resources Management (NRM) Board and the

Department for Environment and Heritage (DEH) has identified a range of pest species and prioritised their management

to protect and enhance biodiversity in the Park over many years.

Board funding in association with technical assistance provided by DEH enabled the development of a project brief

specifying baseline data to be collected for the development of a Pest Prioritisation Report for the Onkaparinga River

National Park (not including Hardy’s Scrub or the Recreation Reserve). The report supports actions identified in the

Onkaparinga River National Park Management Plan and will be a foundation for the development of a Vegetation

Management Plan for the Onkaparinga River National Park.

The partnership contracted Creation Care to collect the data and provide the foundation for this document.

Summary During May and June of 2009, large areas of the Onkaparinga River National Park (1190 ha) were surveyed to ground

truth Native Vegetation Condition and Vegetation Type, and to record the exotic species present and make

recommendations for Priority Actions. Approximately 652 ha and 37 individual management areas were surveyed using

data collection sheets. A total of 73 introduced species were recorded (Appendix 4).

A summary table of each category surveyed is provided below with the areas ranked according to Biodiversity value:

The categories Cleared and Unknown did not get surveyed during the program due to funding constraints. The maps for

these areas have been included in this report.

There were four areas excluded from this survey due to survey work already underway for DEH’s Urban Biodiversity

Unit. These areas are highlighted on the map (Appendix 1).


Introduction During May and June 2009 survey work was undertaken over approximately 652 ha and 37 individual management areas

within Onkaparinga River National Park (ORNP) to collect information allowing the prioritisation of pest control within

the park. The information collected included the Vegetation Type and Condition but was primarily focusing on the pest

species present within each area. The assessment methodology used is outlined below.

Assessment Methodology A desktop classification of ORNP by the Department of Environment and Heritage (DEH) provided a basic division of the

park into five categories (see Appendix 1 for a map of the areas). These categories are listed below in order of survey

priority:

1. Remnant vegetation areas (RM) 250 hectares

(Endemic vegetation)

2. Revegetation areas (RV) 277 hectares

3. Riparian areas (RA) 125 hectares

4. Cleared areas (CA) 172 hectares

(Degraded grazing land; scattered exotic grasses, woody weeds and olive)

5. Unknown vegetation (UV) 366 hectares

(Primarily exotics - high concentration of olives)

A data collection sheet specifying the information to be gathered during the ground truthing was supplied to the

contractor (Appendix 2). The condition of native vegetation in each of the areas was scored using the below table as

supplied by the Department for Environment and Heritage, Vegetation Management Plan process (also Appendix 3).

Class 5 Excellent Largely undisturbed and healthy.

Class 4 Good Minor weed infestation which is manageable and

high cover and native species and high species

diversity.

Class 3 Moderate Weed infestation is manageable, or weeds of lower

priority dominate; moderate cover and/or diversity

of native species.

Class 2 Residual The basic habitat structure remains; low species

diversity and low cover of native species.

Class 1 Poor Dominated by exotic species; very low species

diversity and cover of native species.


The field survey work began in the highest priority areas (Remnant Veg- RM areas). Each area was covered on foot and

the data collection sheets were used to record the relevant information. If an area was quite small (i.e. RM1) a single

person was delegated to survey the whole area, and as the areas increased in size more people were delegated to the

site. The largest site (RM14) had four people walking approximately 150m away from each other in an ‘emu walk’

through the site, zig-zagging out from their path, and meeting up at the end of the site to compile the individual results.

This allowed the whole site to be covered in a minimal amount of time, and also allowed the spread of particular weeds

to be determined. For example, if the two people on the eastern side of the site identified very dense olive, the third

person in the middle identified moderate density olive and the person on the western side identified low density olive, it

is reasonable to record that the olive is primarily concentrated on the eastern side of the site.

The weed density was categorised into Low, Medium or High but was not based on any recognised quantitative

classification system. It is a subjective classification due to the scale of the site and the ‘walkthrough’ method used for

the survey.

All data gathered in the field was collected in an opportunistic fashion and the survey timing may have limited the

number of species recorded due the seasonal nature of different weed species.

The information from the data collection sheet was transferred to an Excel document for analysis, from which a

summary table of priority sites was compiled, ranking the areas from highest value to lowest value based on the level of

native vegetation present and its condition, the number of exotic species present and the level of infestation. In the

tables for each area surveyed, a recommendation has been made for exotic species to be targeted for control. In the

example below, pest species prioritised for control are highlighted in red.

African Daisy Low

Boxthorn Low

Capeweed Medium

Cotton Bush Low

Dock Low

* It is worth noting that the African Feather Grass and Olive infestations cover large areas of the entire Onkaparinga

River banks and would be having significant effects on the ability of the native species to regenerate effectively.

However, the African Feather Grass has not been listed for control as a ‘Priority Action’ as the control recommended is

manual removal of all plants and rhizomes, or chemical control requiring vast quantities of chemical mix in places that

are inaccessible, both of which would be unfeasible.

It is suggested instead, that a containment principle is applied and that the whole of the Onkaparinga River is monitored

and isolated infestations/individuals are controlled to stop the spread.

The results of the survey follow.

Surveyor: Nat Doecke, James Ryan & Elijah Jewell, Creation Care

Date: 25/05/2009

Vegetation Type: Eucalyptus microcarpa woodland, Allocasuarina verticillata woodland, Eucalyptus camaldulensis woodland (see comments)

Condition: Moderate

Comments:

This site could be divided into the three different vegetation types listed above. The northern area has good remnant Eucalyptus microcarpa with reasonable understorey, whilst the middle and steeper sections have an Allocasuarina verticillata overstorey and the lower section closer to the Onkaparinga River has a Eucalyptus camaldulensis overstorey. The condition scores moderate as a whole, but if it was divided into three areas each vegetation community would differ slightly in its condition score, with the better condition vegetation existing at the northern end of the site. The site has largely been damaged by fire (estimated 3 + years ago) and the areas damaged by fire have moderate regeneration occurring, primarily Acacia, Dodonaea and Eucalyptus species.

Priority Actions:

African Daisy and Olive require spray unit and cut/swab control along the eastern edge of the site. Watsonia and Ash at the southern end of the site require spraying and cut/swab control.

R M8

Location/Area: RM8


Date: 25/05/2009

Vegetation Type: Eucalyptus microcarpa closed forest

Condition: Moderate

Comments:

This site overlaps Urban Biodiversity Unit involvement, and as such only the eastern end of the site has been surveyed (all density information refers only to the eastern end of the site). The site has excellent remnant Eucalyptus microcarpa with patches of Acacia rupicola and Acacia paradoxa understorey, however it is predominantly an Olive understorey. The eastern end of the site is dangerously steep with a shale ground. The Olive is interfering with native understorey regeneration.

Priority Actions:

Olive control required using spray unit and cut/swab, however great care needs to be taken due to the extreme slope. Cotton Bush can be controlled at the same time. Bridal Creeper spray or hand grubbing required and an African Daisy spray or hand pull desired.

R M1 1

Location/Area: RM11

Surveyor: Sam Dalton & Nat Doecke, Creation Care

Date: 20/05/2009


Condition: Moderate

Comments:

The entire site is fire damaged (estimated 3 + years ago), with the remnant Eucalyptus microcarpa starting to reshoot now. The site has a high number of Dodonaea viscosa, Acacia rupicola and Acacia paradoxa regenerating also. It is also quite steep. The condition was scored as moderate, as despite the fire there is still a high diversity of native species and quite a low quantity of weeds.

Priority Actions:

The site has a relatively low quantity of weeds, a quick sweep through for African Daisy, Olive and Bridal Creeper using spray unit control would be sufficient weed control. It would be beneficial to increase the understorey diversity also.

RM12

Location/Area: RM12

Surveyor: Sam Dalton, Nat Doecke, Elijah Jewell & James Ryan, Creation Care

Date: 20/05/2009

Vegetation Type: Eucalyptus microcarpa woodland, Acacia paradoxa shrubland, Eucalyptus microcarpa open forest (see comments)

Condition: Residual

Comments:

This site could be divided into the three different vegetation types listed above. There is a patch of dense Acacia paradoxa shrubland at the northern end of the site, two strips of Eucalyptus microcarpa open forest stretching out into the open land in the middle of the site, and fire damaged Eucalyptus microcarpa woodland at the western end of the site. The condition was scored as residual as a whole, but if it was divided into three areas each vegetation community would differ slightly in its condition score. The Acacia paradoxa shrubland is in good condition, the Eucalyptus microcarpa open forest areas are in poor condition and the remainder of the site is in moderate condition. There are large open areas in this site also. The site has largely been damaged by fire (estimated 3 + years ago).

Priority Actions:

Olive control required with spraying and cut/swab control, African Daisy and Bridal Creeper spraying control in the burnt areas. Any Dog Rose and Cotton Bush in the controlled area could be controlled at this time also. Ash, Broom and Watsonia control along the Onkaparinga River. Phalaris control along the open drainage lines. To return the whole site to a Eucalyptus microcarpa woodland, large areas need total revegetation.

Location/Area: RM13


Date: 20/05/2009

Vegetation Type: Allocasuarina verticillata closed forest, Eucalyptus fasciculosa +/- Allocasuarina verticillata woodland (see comments)

Condition: Good

Comments:

There are excellent patches of dense Allocasuarina verticillata closed forests in the steeper, rockier parts of the site, with patches of Eucalyptus fasciculosa +/- Allocasuarina verticillata woodland in the remainder of the site. Eucalyptus camaldulensis are also present at the southern end of the site adjacent to the Onkaparinga River. The site has more weeds the closer it is to the Onkaparinga River. There are also thick patches of Acacia paradoxa understorey. Parts of the site are dangerously steep. *There is a reasonable amount of dead Xanthorrhoea semiplana which could indicate disease (Phytophthora)*.

Priority Actions:

Continued Olive control with spraying and cut/swab in the north-western areas as a priority, and worth controlling the Cotton Bush in that area at the same time. Bridal Creeper requires spraying or hand grubbing control also. Watsonia, Dog Rose and Ash along the Onkaparinga River boundary requires spraying or cut/swab control.

Location/Area: RM14


Date: 20/05/2009

Vegetation Type:

Eucalyptus microcarpa +/- Eucalyptus fasciculosa woodland, Allocasuarina verticillata closed forest, Callitris rhombodia closed forest, Eucalyptus microcarpa woodland, Eucalyptus fasciculosa woodland (see comments)

Condition: Good

Comments:

This site could be divided into four different areas. The northern most area distinguished by the narrow junction at Gate 7 is primarily a Eucalyptus microcarpa +/- Eucalyptus fasciculosa woodland (possibly even an open forest). The middle area starting at the narrow junction at Gate 7 and moving until the next narrow junction above RA7 has excellent patches of dense Allocasuarina verticillata closed forests in the steeper, rockier parts of the site, with patches of Callitris rhombodia closed forest in the remainder of the site. The north-western edge of this site has some Eucalyptus fasciculosa woodland. The remainder of the site is predominantly a Eucalyptus microcarpa woodland. There are also thick patches of Acacia paradoxa shrubland, and most of the area has reasonable understorey. Parts of the site are dangerously steep. The southern end of the site as well as a patch in the northern end of the site has been damaged by fire (estimated 3 + years ago).

Priority Actions:

Olive is the primary weed needing control. Control work has and is being completed in the northern area of the site. This should be continued across the whole site with spraying and cut/swab, however, the Olive in the southern end of the site has been fire damaged and is not in the optimum control stage. The remainder of the Ash, Watsonia and Phalaris in the northern area of the site controlled also. The Radiata Pine found at the southern end of the site should be controlled, and any Cotton Bush and Dog Rose in the same vicinity controlled. African Daisy is a secondary priority also.

Date: 20/05/2009

Vegetation Type: Eucalyptus fasciculosa woodland

Condition: Excellent

Comments:

This site has excellent remnant vegetation, both the overstorey and understorey layer with good groundcovers and grasses present also. There is some fire damage to small areas of the site. Since it is close to the road, it has scattered rubbish through it.

Priority Actions:

Control the Bridal Creeper along the roadside to stop it spreading into the rest of the site. A thorough scouting for Olive, Cotton Bush and African Daisy using knapsack control would likely be sufficient to keep it in excellent condition.

Comments:

The revegetation is quite healthy and advanced in growth with a good diversity of species such as Acacia paradoxa, Acacia pycnantha, Melaleuca lanceolata, Dodonaea viscosa & Allocasuarina verticillata. There are significant patches of open, weed infested areas amongst the revegetation.

Priority Actions:

A sweep through for Olive, Boxthorn, Sodom Apple, False Wattle, Coastal Wattle and Scotch Thistle should be completed. More overstorey species are needed in the western 'point' of this site, and plantings needed in the open areas once the weeds have been removed.

Surveyor: Elijah Jewell, Creation Care

Date: 26/05/2009

Vegetation Type: Eucalyptus porosa woodland, Acacia pycnantha +/- Dodonaea viscosa shrubland, Eucalyptus microcarpa woodland (see comments)

Condition: Residual

Comments:

This site could be divided into four areas. The western most end is a revegetated Eucalyptus porosa woodland in reasonable condition with moderate diversity of native plants. The middle area has a large patch of open weedy grassland and an area of revegetation with primarily Acacia pycnantha and Dodonaea viscosa surviving. The eastern end has some remnant Eucalyptus microcarpa as well as revegetated species and is in moderate condition. But as a whole the site is very degraded and the diversity of species should be increased.

Priority Actions:

The Olive, Boxthorn, African Daisy and Scotch Thistle invading from the southern edge can all be controlled at the same time using spraying and cut/swab control. The Coastal Wattle and Pepper Tree should be controlled using cut/swab.

Condition: Residual Comments:

The revegetation consists predominantly of Acacia pycnantha but is quite scattered in its success.

Priority Actions:

Olive control is the primary action required, but it is worth controlling the African Daisy, Cotton Bush, Scotch Thistle and Sodom Apple at the same time. Kikuyu and Phalaris will become more of a problem if left; control of these two is desirable also. The revegetation needs infill with a greater number and diversity of species after weed control is complete.

R V7

Location/Area: RV7

Surveyor: Sam Dalton, Nat Doecke & Elijah Jewell, Creation Care

Date: 26/05/2009


Condition: Poor

Comments:

This is quite a large site with several distinctive changes in its vegetation structure. There are four patches of thick, direct seeding revegetation consisting mainly of Acacia rupicola, Acacia paradoxa, Dodonaea viscosa and other scattered species. These patches are located at the very western corner, the very eastern corner, directly below RM5 and directly above RM6. There are also patches of older plantings of Eucalyptus microcarpa, Allocasuarina verticillata and Eucalyptus fasciculosa which are quite advanced but have no understorey. There are also open patches where little to no native vegetation exists and are almost entirely dominated by olives. Some of the gullies have erosion problems with a reasonably large soil slip in the eastern most drainage line. Portions of the site in the eastern area have been damaged by recent fires (estimated < 2 years ago). Parts of the site are very steep.

Priority Actions:

Olive is the dominant weed requiring control. The patches marked on the map with dense Olive require spraying and cut/swab control and the rest of the site needs a sweep with spray control. It is worth controlling the African Daisy, Boxthorn, Bridal Creeper, Cotton Bush, Dog Rose and Scotch Thistle at the same time. The Phalaris in the open northern patches require spraying control It is suggested that the site is divided up into different zones depending on the age and method of revegetation and further plantings take place after the control discussed above is completed.

RV8

Location/Area: RV8


Date: 26/05/2009

Vegetation Type: Eucalyptus microcarpa +/- Eucalyptus fasciculosa woodland (target)

Condition: Residual

Comments:

This site has a reasonable overstorey of Eucalyptus microcarpa and Eucalyptus fasciculosa with parts of the site having moderate understorey also. Fire has damaged a lot of the site but regrowth is already occurring. Parts of the site are very steep.

Priority Actions:

African Daisy is the primary concern and should be controlled using spraying, the Olive and Cotton Bush can be controlled at the same time. The Broom is primarily located along the eastern side of the site and requires spraying. The Phalaris and Watsonia should be controlled at the same time using spraying. The Bridal Creeper should be controlled also.

R V1 0

Location/Area: RV10


Date: 26/05/2009


Condition: Residual

Comments:

This site is a mixture of associations and conditions, it is partly composed of remnant Eucalyptus fasciculosa, Eucalyptus microcarpa and Eucalyptus leucoxylon, the south- eastern areas have good quality revegetation with primarily a Eucalyptus microcarpa +/- Eucalyptus leucoxylon overstorey mix, but the northern and western parts of the site are largely cleared land with very high weed content. As a result the site overall has been scored as poor, even though there are quite successful patches of revegetation within it. The revegetation at the south-eastern end has good diversity and weed suppression. The Phalaris patches in particular are having an impact on native regeneration.

Priority Actions:

Slash and boom spray the patches of Phalaris in preparation for revegetation. Spraying control required for African Daisy, Olive, Cotton Bush, Bridal Creeper and Scotch Thistle. Cows to be removed from the site. Open areas to be revegetated.

Location/Area: RV11


Date: 26/05/2009

Vegetation Type: Eucalyptus microcarpa +/- Eucalyptus leucoxylon closed forest (target)

Condition: Moderate

Comments: The revegetation is quite thick and well established with low amounts of understorey such as Acacia paradoxa, Acacia acinacaea, Dodonaea viscosa and Acacia rupicola.

Priority Actions:

A sweep through the entire site for Olive, African Daisy and Bridal Creeper would be sufficient to keep the site relatively clean of high problem weeds. More understorey revegetation would be beneficial to increase the diversity.

R V1 2

Location/Area: RV12


Date: 26/05/2009

Vegetation Type: Eucalyptus microcarpa +/- Eucalyptus fasciculosa woodland (target)

Condition: Moderate

Comments:

This site has reasonable understorey success but moderate overstorey success. It is dominated by Acacia paradoxa, Dodonaea viscosa, Acacia rupicola and selected understorey species. There are small numbers of Eucalyptus microcarpa, Eucalyptus fasciculosa and Allocasuarina verticillata also from the revegetation. It could be divided into two different areas; the long thin strip of revegetation at the eastern side of the site has a higher proportion of overstorey species, whilst the remainder of the site has a higher proportion of understorey species.

Priority Actions:

A sweep of the site for African Daisy, Bridal Creeper, Olive and Wild Mustard is suggested, as well as the control of the patches of Phalaris along the northern boundary. Increasing the overstorey species in the main area and the understorey species in the eastern thin strip is desirable.

Condition: Poor

Comments:

This is largely an open area with grassy weed ground cover; there are some steep slopes and cliffs leading down to the river with woody weeds growing along the base of the cliffs. Poor native diversity and only scattered remnant Eucalyptus camaldulensis.

Priority Actions:

Cut and swab and spray control for Itchy Powder tree, Boxthorn, Olive, Pepper Tree as a priority. A walk along the entire length of the area releasing Bridal Creeper rust would be desirable. Fennel could be sprayed at the same time as the initial woody weeds. Prickly Pear control with drill & fill is desirable. Increasing the diversity of natives is desirable.

Location/Area: RA2


Date: 9/06/2009


Condition: Residual

Comments:

This area has a moderate number of remnant Eucalyptus camaldulensis and patches of reasonable quality understorey. The weed presence is very high though, especially in the centre of the area at the western edge of CA3. Parts of the site are quite steep.

Priority Actions:

A cut & swab sweep through the site for mature Ash, Boxthorn, Dog Rose, Fig and Olive with a follow up spray for immature plants of the same species is suggested initially. A walk along the entire length of the area releasing Bridal Creeper rust would be desirable. Spray control for the Lavender and Scotch Thistle is desirable. Drill & fill control for the Century Plant is desirable, but it is a slow growing species that is not likely to spread quickly. Increasing the native diversity is desirable also.

Comments:

This site has patches of native understorey and a moderate number of remnant Eucalyptus camaldulensis. Callistemon sp is common along the river. Parts of the site are very steep with cliffs to the water’s edge; Olive is growing through the whole site and is quite the dominant weed.

Priority Actions:

A cut & swab sweep through the site for mature Olive, Ash, Boxthorn, Dog Rose and Radiata Pine with a follow up spray for immature plants of the same species is suggested initially. A walk along the entire length of the area releasing Bridal Creeper rust would be desirable. Spray control for the Broom, Cotton Bush, Fennel, Scotch Thistle and Watsonia is desirable. Drill & fill control for the Prickly Pear is desirable, but it is a slow growing species that is not likely to spread quickly. Increasing the native diversity is desirable also.

Comments:

This area has moderate amounts of remnant Eucalyptus camaldulensis and the spread of weeds is pretty consistent throughout the whole site. There are moderate amounts of Callistemon sp, Bursaria spinosa and Acacia sp through the whole site also. Cliffs and steep slopes are common along the whole area.

Priority Actions:

A cut & swab sweep through the site for mature Ash, Dog Rose, False Wattle, Fig and Olive with a follow up spray for young plants of the same species is suggested initially. A walk along the entire length of the area releasing Bridal Creeper rust would be desirable. Spray control for the Broom, Fennel, Periwinkle and Watsonia is desirable. Drill & fill control for the Prickly Pear is desirable, but it is a slow growing species that is not likely to spread quickly. Increasing the native diversity is desirable also.

Comments:

This is a beautiful area with steep, shale covered slopes in parts, cliffs in other parts, deep waterholes and waterfalls along the western end and patches of Callistemon sp and Acacia sp understorey with scattered Eucalyptus camaldulensis overstorey. The site has a high presence of Olive though, especially on the slopes.

Priority Actions:

Cut & swab control for the mature Ash, Crested Wattle, Fig and Olive is the key action, with spray control for younger plants. A walk along the entire length of the area releasing Bridal Creeper rust would be desirable. Drill & fill control of the Prickly Pear is desirable, as is spray control of the Watsonia.

RA6

Location/Area: RA6


Date: 9/06/2009


Condition: Moderate

Comments:

This area has some good Eucalyptus camaldulensis regeneration at the eastern end and has quite a bit of good, diverse understorey in patches through most of the area. This is probably one of the best parts of the Riparian areas in the park. There are steep cliffs on both sides, more so at the western end. The site has long stretches of smooth rock which is quite slippery when wet and makes walking dangerous.

Priority Actions:

Initial cut & swab control of mature Olive and Dog Rose with a follow up spray control as a priority. Control of the dense patch of Phalaris at the eastern end of the area is a second priority and spray control of the Watsonia also. Cotton Bush and Fennel could be done at the same time. Release of Bridal Creeper rust along the whole length is desirable. Prickly Pear drill & fill is desirable. Access to this site for spray control would be very difficult.

R A7

Location/Area: RA7


Date: 9/06/2009


Condition: Moderate

Comments:

This area could be divided into three different management zones. From the eastern end up until the beginning of RA8 is a Eucalyptus camaldulensis woodland with moderate amounts of riparian understorey, then the section opposite RA8 is mainly composed of steep, inaccessible cliffs with Olive the main living species. The final section, from the end of RA8 to the western end of RA7 is also a Eucalyptus camaldulensis woodland but more degraded than the eastern end. Overall though, it is comparable in quality to RA6.

Priority Actions:

Cut & swab control for mature Ash, Dog Rose and Olive with spray control for young plants of the same species. Bridal Creeper rust spread through the whole site would be desirable. The Blackberry and Couch at the Eastern end and the Phalaris at the eastern end should be sprayed. The Watsonia through the whole site should be sprayed and the scattered Arum Lily and Cotton Bush could be done at the same time. The Prickly Pear requires drill & fill control but is a slow growing plant and difficult to access in some places. Access to the middle of this site for spray control would be very difficult.

RA8

Location/Area: RA8


Date: 9/06/2009


Condition: Residual

Comments:

This area has primarily Eucalyptus camaldulensis remnant vegetation along the river, but up in the north-eastern corner there are some pines also. Understorey is fairly poor along the riverbanks with slightly higher diversity and density in the north-eastern corner. This area is the most difficult to access out of all of the Riparian areas. The distance from tracks and roads and the steep slopes would make it extremely difficult to get within spraying range of the main riverbanks, and walking up and down to refill knapsacks would be extremely inefficient.

Priority Actions:

Cut & swab control for mature Ash, Fig, Hawthorn and Olive is the primary action. This should be followed with spray control for young plants of the same species, but access to this site for spray control would be very, very difficult. Spreading Bridal Creeper rust along the whole site is desirable, and spraying the Watsonia desirable also. The Prickly Pear should be drill & filled.

R A9

Location/Area: RA9

Surveyor: Sam Dalton & Elijah Jewell, Creation Care

Date: 27/05/2009


Condition: Residual

Comments:

The Eucalyptus camaldulensis along this section of the river are quite old and there is regeneration occurring. The understorey is patchy with some areas quite diverse and other areas with almost no native understorey. The weed count is very high, so overall it was deemed a residual site.

Priority Actions:

Spray control of the Kikuyu is a priority as it is fast growing and very invasive, and establishment of native grasses in its place. Cut & swab of the mature Ash, Dog Rose, Fig, Hawthorn, Olive and Radiata Pine and follow up spray control of young plants of the same species. Arum Lily, Blackberry and Watsonia could be controlled with a walkthrough with knapsacks as the density is low. Spreading Bridal Creeper rust through the whole site would be desirable, as would drill & fill control of the Prickly Pear. Revegetation increasing the understorey diversity would be desirable.

R A1 0

Location/Area: RA10


Date: 27/05/2009


Condition: Residual

Comments:

This area has good quality remnant Eucalyptus camaldulensis and along the main river some good areas of Callistemon sp, Bursaria spinosa and other understorey species, but overall it is dominated by Olive. The site is relatively flat and accessible.

Priority Actions:

Cut and swab the mature Ash, Dog Rose, Fig and Olive and spray control the young plants of the same species. Spray control of Blackberry and Phalaris also, some Blackberry control has been done but follow-up is required. The large open areas of land would be good for revegetation projects once the weed control is completed.
