Summary

Bushland is a precious and highly valued resource within the Lane Cove River Catchment. The purpose of this Bushland Inventory is to obtain a greater understanding of the bushland within the catchment, to ensure the preservation and enhancement of this bushland and its related biodiversity.

This Bushland Inventory consists of four 1:10 000 scale maps and an accompanying technical report.

These four maps display:

1. Bushland Condition
1. Bushland Management, Reserves and Bush Regeneration
1. Canopy with and without understorey
1. Vegetation Communities and Threatened Species and Communities

This technical report discusses the physical aspects of the Lane Cove River Catchment and the maps, includes a Reserve Inventory for the catchment and makes recommendations from the findings of the Bushland Inventory.

1.0 Introduction

The Lane Cove River Catchment is shown on the map below. It is located north west of Sydney Harbour and includes the suburbs of Chatswood, Eastwood, Epping, Gordon, Greenwich, Hornsby, Hunters Hill, Lane Cove, Lindfield, North Ryde, Ryde, Thornleigh, Turramurra and Wahroonga.

It is a widely developed urban catchment which has significant natural resources represented by the river system and the extensive bushland of the Lane Cove River Valley. Parts of seven local government areas, and the Lane Cove National Park, make up the Lane Cove River catchment. These council areas are Hornsby Shire, Hunters Hill, Ku-ring-gai Municipal, Lane Cove, Parramatta City, Ryde City and Willoughby City.

The aims of this Bushland Inventory are to preserve and enhance bushland and related biodiversity in the Lane Cove River Catchment and to identify major threats to bushland quality.

The objectives of this Bushland Inventory are:

1. To provide resource information to land managers to achieve coordinated management of bushland across the catchment.
2. To identify knowledge gaps and opportunities for preserving and enhancing bushland and related biodiversity in the catchment.
3. To identify present bushland ownership and management responsibility.
4. To identify threatened species and habitat.

By fulfilling these aims and objectives, the LCRCMC hopes to achieve a more informed and coordinated approach to bushland management within the catchment.

2.0 Physical Aspects of the Lane Cove River Catchment

2.1 Vegetation communities

There are thirteen vegetation communities found within the Lane Cove River catchment as described by Benson and Howell (1994). These are:

( where for example:

• 4a = the map unit Estuarine Complex = the common name

i) Open-scrub = the structure as defined by Specht (1970) of Avicennia marina- Aegiceras corniculatum = the main canopy species)

• 4a Estuarine Complex
• • i) Open-scrub: Avicennia marina- Aegiceras corniculatum
  • ii) Herbland: Sarcocornia quinqueflora- Suaeda australis
  • iii) Rushland: Juncus kraussii- Phragmites australis
  • iv) Low open-forest: Casuarina glauca- Baumea juncea

• 6b Blue Gum High Forest

• 6c Glen Forest
• • i) Tall open forest: Eucalyptus saligna

• 9o Turpentine-Ironbark Forest

• 10ag Sydney Sandstone Gully Forest
• • i) Open-forest/Woodland: Eucalyptus piperita-Angophora costata-Eucalyptus gummifera
  • ii) Tall open-forest: Eucalyptus pilularis-Syncarpia glomulifera, (also Eucalyptus piperita and Angophora costata)
  • iii) Closed-forest: Ceratopetalum apetalum- Tristaniopsis laurina

• 10ar Sydney Sandstone Ridgetop Woodland

• 27a Coastal Swamp Forest Complex
• • iii) Scrub: Melaleuca linarifolia- Melaleuca styphelioides
  • iv) Reedland: Phragmites australis- Typha orientalis

There are also two other vegetation communities found within the catchment that are not described by Benson and Howell (1994) but are described by Lane Cove Council. These are:

• Sydney Shale/Sandstone Transition Complex

• Sydney Sandstone Rocky Foreshore

Three of these vegetation communities have been listed as Endangered Ecological Communities under the Threatened Species Conservation Act (1995). The definition of an ecological community is ‘an assemblage of species occupying a particular area.’ These endangered ecological communities are:

• Blue Gum High Forest
• Shale/Sandstone Transition Forest
• Turpentine-Ironbark Forest

2.2 Fauna

The Lane Cove River Catchment has a great variety of fauna for an urban catchment, including 27 threatened fauna species (see Section 3.4.2).

Native mammals found within the catchment include the Brushtail Possum, Ringtail Possum, Sugar Glider, Long-nosed Bandicoot, Stuarts Marsupial Mouse, Swamp Wallaby, Short-beaked Echidna, Southern Bush Rat, Water Rat, Grey-headed Flying Fox, Mastiff Bat, Common Bentwing Bat and Gould’s Wattle Bat.

Birds species include the Spotted Pardalote, Eastern Spinebill, Superb Fairy Wren, White-browed Scrubwren, Noisy Miner, Willie Wagtail, Kookaburra, Eastern Rosella, Crimson Rosella, Galah, Pied Currawong, Raven, Magpie, Pacific Black Duck, Wood Duck, Swamphen, Dusky Moorhen, Eurasian Coot, Cormorant, Azure Kingfisher, Sacred Kingfisher, Forest Kingfisher, Banded Rail, Boobook Owl and White-faced Heron.

There are approximately 30 species of lizards and several snakes found within the catchment. These include the Southern Leaf-tailed Gecko, Golden Crowned Snake, Eastern Brown Snake, Red Bellied Black Snake, Diamond Python, Blind Snake, Eastern Blue Tongued Skink, Eastern Long-necked Tortoise and the Short-necked Tortoise.

Approximately 17 species of frogs have been identified in the catchment over the last few decades but it is not known whether all of these species are still present within the area. Known species include the Sydney Froglet, Red-crowned Toadlet, Brown-striped Frog, Verreaux’s Frog, Peron’s Tree Frog and Eastern Dwarf Tree Frog.

Seven species of native fish have been identified within the Lane Cove River and its tributaries. These include the Short-finned Eel, Long-finned Eel, Australian Bass, Native Minnow, Coxes Gudgeon, Striped Gudgeon and Australian Smelt.

2.3 Geology and geomorphology

The geology of the Lane Cove River Catchment consists of Hawkesbury Sandstone overlain by thin layers of Wianamatta Shale along the northern ridges of the catchment.

These two geological units were formed about 230 million years ago at the beginning of the Triassic period when rivers eroding inland mountains began delivering enormous quantities of sand, silt and clay to the coast. These sediments accumulated on the Sydney Basin where the sandy sediments cemented into sandstone and the finer silts and clays to mudstone and shale. The Wianamatta Shale was formed above the Hawkesbury Sandstone.

Over thousands of years rivers eroded the shale and sandstone, forming a sandstone valley. The Wianamatta Shale remained as caps along some of the long narrow ridges. This is today the Lane Cove River Valley. Once the valley was incised the river and its tributaries have deposited alluvium along the river forming the loamy banks that exist today within the Lane Cove River.

2.4 Soils

There are nine different soil landscapes within the Lane Cove River Catchment, as described in Chapman and Murphy (1989). These soil landscapes are divided into those formed by residual, colluvial, erosional or fluvial processes, and are:

Residual soils

• Lucas Heights (lh) soils: are moderately deep (50-150 cm) and occur on the crests and ridges of plateau surfaces of Wianamatta Shale.

• Hornsby (ho) soils: are deep (150-300 cm) and occur on the gently undulating rises to steep low hills on deeply weathered basaltic breccia or diatremes (volcanic necks).

Colluvial soils

• Hawkesbury (ha) soils: are shallow (>50 cm) and occur on steep rugged slopes and ridges of Hawkesbury sandstone.

• West Pennant Hills (wp) soils: are deep (>200 cm) and occur on the steep, narrow, generally south west facing hill slopes of Wianamatta Shale.

Erosional soils

• Lambert (la) soils: are shallow (<50 cm) and occur on undulating to low hills on Hawkesbury sandstone.

• Gymea (gy) soils: are shallow to moderately deep (30-100 cm) and occur on undulating to rolling rises and low hills on Hawkesbury sandstone.

• Glenorie (gn) soils: are shallow to moderately deep (<100 cm) and occur on undulating to rolling low hills on Wianamatta Shale.

Fluvial soils

• Deep Creek (dc) soils: are deep (>200 cm) and occur on level to gently undulating alluvial floodplain draining Hawkesbury Sandstone.

• Lane Cove (lc) soils: are deep (>200 cm) and occur on level to gently undulating alluvial floodplain draining both the Wianamatta Shale and Hawkesbury Sandstone.

3.0 Maps

3.1 Bushland Condition

Ku-ring-gai Municipal Council’s weed classification system has been adopted for the purpose of mapping the bushland condition of the Lane Cove River catchment.

This system has four weed classes:

• Weed Class 1 (Green): bushland with <10% weed cover.
• Weed Class 2 (Yellow): bushland with 10-30% weed cover.
• Weed Class 3 (Orange): bushland with 31-60% weed cover.
• Weed class 4 (Red): bushland with >60% weed cover.

This weed classification system is explained in detail in Ku-ring-gai Municipal Council’s Bushland Weed Assessment Guidelines in Appendix 1.

3.1.1 Methodology

This system was chosen because Hornsby Shire Council and Lane Cove National Park have also mapped their vegetation condition using this system, and collectively these three areas cover the majority of bushland within the Lane Cove River catchments.

Councils that have the condition of their bushland mapped using systems other than the Ku-ring-gai Municipal Council system are Hunters Hill, Lane Cove and Ryde City. Willoughby City Council provided the LCRCMC with verbal information on vegetation condition for each reserve within the Lane Cove River catchment.

Hornsby Shire Council

While Pennant Hills Park has been mapped using the weed classification system mentioned above, the rest of Hornsby Shire Council’s bushland within the Lane Cove River Catchment has been mapped using a four-division weed intensity rating. These are ‘low intensity’ for where the majority of the area is weed free, ‘moderate intensity’ for where the percentage cover of natives is greater than weeds, ‘high intensity’ for where the percentage cover of natives is equal to weeds and ‘severe intensity’ for where the percentage cover of natives is less than weeds. This map of weed infestation is found in Shire of Hornsby Inventory of Bushland Reserves (1990).

Table 1 shows how these categories have been fitted into the Ku-ring-gai Municipal Council system

Hunters Hill Council

The bushland condition of reserves in Hunters Hill has been mapped using the National Trust’s categories for bushland condition. These are ‘good condition’, ‘fair condition’, ‘poor condition’ and ‘very poor condition’.

Table 1 shows how these categories have been fitted into the Ku-ring-gai Municipal Council system.

The three reserves in Hunters Hill council area were mapped at scales of 1:1,000 and 1:2,000. Because of this small scale some of the detail on these maps was too small to show on the 1:10,000 scale bushland condition map. In this case the major weed class area/s within each reserve were mapped. The detailed bushland condition maps of the three reserves in Hunters Hill as produced in Hunters Hill Bushland Survey, The National Trust of Australia (New South Wales) (1990) are available from the LCRCMC office.

Lane Cove Council

The bushland condition within Lane Cove has been mapped using a six- division weed intensity rating. These are ‘weed free’, 0-10% weed; ‘light weed infestation’, 10-25% weed; ‘medium weed infestation’, 25-50% weed; ‘heavy weed infestation’, 50-90% weed; ‘very heavy weed infestation’, 90-100% weeds and ; ‘bush landscape’.

Table 1 shows how these categories have been fitted into the Ku-ring-gai Municipal Council system.

The bushland areas in Lane Cove were mapped at 1:2,000 scale. Because of this small scale some of the detail on these maps was too small to show on the 1:10,000 scale bushland condition map. In this case the major weed class area/s within each reserve were mapped. The detailed weed intensity maps of bushland in Lane Cove were obtained from the Annual Reports of each Bush Regeneration site in Lane Cove prepared for Lane Cove Council.

Ryde City

The bushland condition of Buffalo Creek in Ryde has been mapped using a four- division bushland condition class. These classes are good bushland (minor weed infestation), fair bushland (moderate weed infestation), poor bushland (heavy weed infestation) and very poor bushland (severe weed infestation).

Table 1 shows how these categories have been fitted into the Ku-ring-gai Municipal Council system.

Table 1: Shows how the different bushland condition and weed intensity categories have been fitted into the Ku-ring-gai Municipal Council Weed Classification system.

3.2 Bushland Management, Reserves and Bush Regeneration

This map displays:

• bushland within the catchment that is not managed by the local councils.
• the areas of land that are proposed to be gazetted as NPWS land and transferred to the Lane Cove National Park.
• the reserves described in the Reserve Inventory (see Section 4.0).
• the reserves described in the Reserve Inventory (see Section 4.0) that receive bush regeneration.

Bushland not managed by local council is managed by either:

• the Lane Cove National Park;
• the Scouts Association (they manage part of Pennant Hills Park);
• Hills Motorway Ltd (the company who manage the M2 Motorway) or;
• Other private managers (see Section 3.2.1).

3.2.1 Private Managers of Bushland

There are 19 other private mangers of bushland within the catchment. These are:

• Hunters Hill High School, Hunters Hill
• St Ignatius College, Lane Cove
• Malvina High School, Ryde
• Macquarie Hospital, Ryde
• North Ryde Golf Club, Ryde
• Ryde North Public School, Ryde
• Macquarie University, Ryde
• Northern Suburbs Crematorium, Ryde
• Northern Suburbs Cemetery, Ryde
• Ku-ring-gai College of Advanced Education, Ku-ring-gai
• National Measurement Laboratory, Ku-ring-gai
• Killara Golf Club, Ku-ring-gai
• Government Laboratory, Ku-ring-gai
• Pymble Ladies College, Ku-ring-gai
• Avondale Golf Club, Ku-ring-gai
• Loreto College, Hornsby
• Sydney Adventist Hospital, Hornsby
• St Benedicts Girl School, Hornsby
• Pennant Hills Golf Club, Hornsby

3.2.2 Methodology

The boundaries of this map were derived from Lane Cove National Park information, Local Environment Plans and the UBD Street Directory.

3.3 Canopy with and without understorey

A purpose of this map is to highlight opportunities for future bush regeneration within Lane Cove River Catchment. Areas of (healthy) canopy without understorey have the potential to regenerate if management practices are changed. For example if the practice of mowing under trees was stopped and bush regeneration activities were undertaken, canopy with previously no understorey could regenerate understorey.

3.3.1 Methodology

This map of canopy with and without understorey was produced using existing bushland maps from councils and the Lane Cove National Park and aerial photograph interpretation. Boundaries are approximate and no field checking was undertaken in producing this map.

3.4 Vegetation Communities and Threatened Species and Communities

This map displays:

• vegetation communities
• threatened species recorded from the National Parks and Wildlife Service (NPWS) Atlas of NSW Wildlife (each species is given a reference number, eg. (1).)
• endangered ecological communities

3.4.1 Vegetation Communities

The Benson and Howell (1994) vegetation communities (or map units) that occur within the Lane Cove River Catchment are:

( where for example:

• 4a = the map unit Estuarine Complex = the common name
• • i) Open-scrub = the structure as defined by Specht (1970) of Avicennia marina- Aegiceras corniculatum = the main canopy species)

• 4a Estuarine Complex
• • i) Open-scrub of Avicennia marina- Aegiceras corniculatum
  • ii) Herbland of Sarcocornia quinqueflora- Suaeda australis
  • iii) Rushland of Juncus kraussii and Phragmites australis
  • iv) Low open-forest of Casuarina glauca and Baumea juncea

• 6b Blue Gum High Forest

• 6c Glen Forest
• • i) Tall open forest: Eucalyptus saligna

There are also two other vegetation communities found within the catchment that are not described by Benson and Howell (1994), but are described by Lane Cove Council. These are:

• Sydney Shale/Sandstone Transition Complex

• Sydney Sandstone Rocky Foreshore

3.4.1.1 Methodology

The descriptions of vegetation communities by Benson and Howell (1994) have been used for the purpose of producing this map of vegetation communities.

Some council areas and the Lane Cove National Park have not used Benson and Howell (1994) descriptions when mapping their vegetation communities. However, it has been possible to change these descriptions to the corresponding Benson and Howell (1994) descriptions for the purposes of producing this Vegetation Communities map of the catchment. Because the Vegetation Communities map is of Benson and Howell (1994) descriptions of communities, the original, or non-Benson and Howell (1994) vegetation community descriptions of bushland within the catchment are given in the reserve inventory within this report (Section 4.0).

3.4.2 Threatened Species

An endangered species is a species that is likely to become extinct in nature unless the factors threatening their survival or evolutionary development cease to operate, or those whose numbers have been reduced to a critical level, or those whose habitats have been so drastically reduced that they are in immediate danger of extinction, or might already be extinct, but not presumed extinct.

A vulnerable species is a species that is likely to become endangered unless factors threatening their survival or evolutionary development cease to operate.

An endangered ecological community is an assemblage of species occupying a particular area that is endangered.

3.4.2.1 Threatened species recorded from the National Parks and Wildlife Service (NPWS) Atlas of NSW Wildlife

5.0 Recommendations

5.1 Bushland Plans of Management

The Local Government Act (1993) requires that councils prepare Plans of Management for all lands under their control which have been classified as community land, which includes bushland. The following is a list of Plans of Management for bushland within the catchment:

• Hornsby Shire Council Generic Plan of Management for Bushland (1996)
• Ku-ring-gai Municipal Council Bushland Plan of Management (1996) (this is a generic Plan of Management).
• Lane Cove Council Plan of Management for Bushland (1996) (this is a specific Plan of Management for bushland reserves within Lane Cove).
• Lane Cove National Park Plan of Management (1998) (this is a specific Plan of Management).
• Parramatta City Council Plan of Management (1996/7) for Edna Hunt Sanctuary (this is a specific Plan of Management).
• Ryde City Council Plan of Management for Buffalo Creek Urban Bushland Corridor (1996) (this is a specific Plan of Management).
• Willoughby City Council Urban Bushland Plan of Management (1997) (this is a specific Plan of Management).

Bushland reserves within the catchment that have Plans of Management are reserves in Lane Cove, Edna Hunt Sanctuary in Parramatta and Buffalo Creek in Ryde.

It is recommended that the LCRCMC establish which bushland reserves within the Lane Cove River catchment have current Site Assessments. This will allow the CMC to establish which bushland reserves in the catchment are lacking either a Plan of Management or Site Assessment.

5.2 Future mapping of bushland condition

Councils should consider developing a common weed classification system.

Different weed classification systems have been fitted into the Ku-ring-gai system for this Inventory so that bushland condition could be mapped on a catchment scale. However, these weed classification systems use generic descriptions of bushland condition while the Ku-ring-gai system uses a more detailed and scientific approach. Combining the information from these different systems into the bushland condition map has probably resulted in a less than accurate view of bushland condition in the catchment. To ensure that accurate comparisons between bushland condition in different council areas can be made in the future, it is recommended that councils develop a common weed classification system.

5.3 Future mapping of vegetation communities

Lane Cove National Park and councils who are not using the Benson and Howell (1994) descriptions to map vegetation communities should consider using this system in the future. Where the Benson and Howell (1994) descriptions do not cover small scale, local variations, it is suggested to use the descriptions as a basic classification system and to add sub-units for local variations.

5.4 Endangered Ecological Communities

5.4.1 Endangered Ecological Communities that do not receive bush regeneration

It is recommended that the following areas of bushland that contain an Endangered Ecological Community be considered a high priority to receive bush regeneration:

• K22 Reserve (Greenway Drive) in Ku-ring-gai which contains Blue Gum High Forest.
• Aluluba Reserve in Ku-ring-gai which contains Turpentine- Ironbark Forest.
• The northern corner of Macquarie University which contains Turpentine- Ironbark Forest.
• The Blue Gum High Forest in Boronia Park (P1), David Hamilton Reserve (P2), Edwin Ross Reserve (P4), Fred Spurway Reserve (P5), George Harley Reserve (P6), Mobbs Lane Reserve (P7), Raimonde Reserve (P8) and Skenes Avenue Reserve (P9), all in Parramatta.

5.4.2 Endangered Ecological Communities that are in poor condition

It is recommended that the following areas of bushland that contain an Endangered Ecological Community be considered a high priority to receive more intensive bush regeneration due to their poor bushland condition:

• A small remnant of Turpentine- Ironbark Forest in Boronia Park, Hunters Hill, that is classified as Weed Class 4 (>60% weeds).
• Blue Gum Reserve in Lane Cove which contains Shale/Sandstone Transition Forest and is classified as Weed Class 4 (>60% weeds).
• A section of Shale/Sandstone Transition Forest in Osborne Park, Lane Cove, that is classified as Weed Class 4 (>60% weeds).
• The section of Blue Gum High Forest in Buffalo Creek Reserve between Princes Street, Turner Avenue and Clayton Street that is classified as Weed Class 3 (31-60%) and Weed Class 4 (>60 % weeds).

5.4.3 Endangered Ecological Communities whose bushland condition is unknown

It is recommended that the bushland condition of the following areas of Endangered Ecological Communities be determined:

• Wallamutta Nature Reserve, Ryde, which contains Turpentine- Ironbark Forest.
• The Turpentine- Ironbark Forest in Marsfield Park and Macquarie University.
• The Blue Gum High Forest in Boronia Park (P1), David Hamilton Reserve (P2), Edna Hunt Sanctuary (P3), Edwin Ross Reserve (P4), Fred Spurway Reserve (P5), George Harley Reserve (P6), Mobbs Lane Reserve (P7), Raimonde Reserve (P8) and Skenes Avenue Reserve (P9), all in Parramatta.

5.5 Private management of bushland

It is recommended that areas of bushland within the catchment that are privately managed be surveyed by the LCRCMC to establish whether they contain any Endangered Ecological Communities and whether they warrant bush regeneration.

These privately managed areas of bushland are listed in section 3.2.1.

5.6 Joint management of bushland

It is recommended that the following areas of bushland be considered for joint management:

• Sugarloaf Point: requires joint management by Lane Cove National Park, Hunters Hill Council, Ryde Council and Malvina High School.
• Bushland between Pittwater Road and Lane Cove River: requires joint management by Ryde Council, Lane Cove National Park and Macquarie Hospital.
• Blue Gum Creek: requires joint management by Lane Cove National Park, Willoughby Council, Ku-ring-gai Council and Ku-ring-gai College of Advanced Education.
• Blackbutt Creek: requires joint management by Ku-ring-gai Council, Lane Cove National Park, Killara Golf Club and Government Laboratory.
• Quarry Creek and Rudders Creek: require joint management by Lane Cove National Park and Ku-ring-gai Council.
• Bushland along the Lane Cove River at Marsfield: requires joint management by Hills Motorway Ltd., Ryde Council, Macquarie University and Lane Cove National Park.
• Twin Creek: requires joint management by Pymble Ladies College, Avondale Golf Club, Ku-ring-gai Council and Lane Cove National Park.
• Lane Cove River at Fox Valley: requires joint management by Lane Cove National Park and Ku-ring-gai Council.
• Coups Creek: requires joint management by Ku-ring-gai Council and Sydney Adventist Hospital.
• Headwaters of Lane Cove River at Thornleigh and Normanhurst: requires joint management by Loreto College, Hornsby Council and the Scouts Association.
• Upper Devlins Creek: requires joint management by Hills Motorway Ltd., Pennant Hills Golf Club and Hornsby Council.
• Lower Terrys Creek: requires joint management by Hills Motorway Ltd., Hornsby Council and Ryde Council.

These areas of bushland require joint management because the activities of these different managers have the potential to impact upon that bushland. One example is if bushland along a creek is being managed by two councils, and one council is managing the upstream section of the bushland and the other council is managing the downstream section of the bushland. The bushland management actions of the council upstream will impact upon the bushland managed by the other council downstream. Another example is where a golf course is upstream of bushland. If the golf course uses fertiliser on its greens, the runoff from the golf course will be high in nutrients, which will promote weed growth in the bushland downstream.

It is also recommended that the LCRCMC establish if, and if so which, councils and the Lane Cove National Park are working together in the management of specific areas of bushland within the catchment. If councils and the National Park are working together in specific bushland management, it is recommended that the CMC establish whether these approaches to joint management have been successful.

5.7 Transfer of land to Lane Cove National Park

It is recommended that when councils consider transferring their bushland to the Lane Cove National Park, they consider transferring it on a subcatchment scale. That is, if a council is considering transferring parts of bushland in a certain subcatchment, they should consider transferring all of the bushland in that subcatchment.

This would mean that all of the bushland in that subcatchment is managed by one authority, and would make management of bushland simpler by reducing differences between natural and administrative boundaries within bushland.

5.8 LCRCMC Workshop on bushland management

It is recommended that the LCRCMC convene a workshop on bushland management with the seven local councils and Lane Cove National Park.

Such a workshop provides an opportunity for the CMC, local councils and the Lane Cove National Park to exchange information and discuss management issues. This would also raise an opportunity for the CMC to undertake and raise the recommendations made from this Bushland Inventory.

The anticipated outcomes from this workshop are:

1. That councils and the Lane Cove National Park make informed bushland management decisions based on a knowledge of the management actions of other councils, to achieve coordinated bushland management on a catchment scale.
1. That councils and the Lane Cove National Park consider recommendations 5.2, 5.3, 5.4.1, 5.4.2, 5.4.3, 5.6 and 5.7 made from this Bushland Inventory.
1. That the CMC undertake recommendations 5.1 and 5.5 made from this Bushland Inventory.
1. That participants consider how best to involve private bushland managers in joint management programmes for bushland.
