In January 2005, the Blue Mountains Council set up a Blue Mountains East Timor Friendship Committee and a friendship relationship with Timor Leste (East Timor) to work with a community in Timor Leste.

The Blue Mountains Council has partnered with Hato Builico, one of the four Sub-Districts of Ainaro District, south west of the East Timorese capital Dili.  The Council developed its ‘Hato Builico Strategic Plan 2008′ to improve the lives of this rural community through funding of a Community Centre Refurbishment, Sustainable Economic Development, Health and Well Being, Capacity Development, Education and Training, Capital Works Infrastructure; and Governance and Partnerships.’

.

This committee has since decided to stage a fundraising event to raise money for East Timorese communities.   The event is called ‘Trek for Timor‘, which seems now scheduled to be held every two years in September.  The route traverses bushland between Wentworth Falls and Katoomba in the Blue Mountains, about 100km west of Sydney.  It passes through the Jamison Valley Wilderness within the Blue Mountains World Heritage Area .   There are four separate distances – 5km, 13km, 25km and 45km options to cater for varying levels of fitness of participants.

.

The Trek Route

.

Section 1 – Charles Darwin Walk through Valley of the Waters to Leura Cascades  (13km trek 7am – 4pm)
Section 2 – Leura Cascades to Katoomba Park & Oval  (25km trek 6am – 6pm)
Section 3 – Katoomba Oval alkong Narrowneck and through the Jamison Valley to Jamison Creek – “an unsupported checkpoint”
Section 4 – Jamison Creek via Kedumba Pass to Queen Victoria Hospital   (45km Trek 6am – 1am)

.

The registration fee is $30 per person to cover costs and in addition each trekker (in teams of four to six) is asked to raise at least $150 in sponsorship for East Timor.

While a few tourist toilets are situated on parts of the course, participants may relieve themselves between checkpoints “make sure you move well off the track, and carry a trowel to dig a small hole to bury your waste.”

.

While the cause seems noble, a key Blue Mountains problem of this event, like the many running that seemed to have cropped up in recent years, is that the Blue Mountains Council has routed the ‘Trek’ through Bushcare restoration sites and through creek beds, and there has been no environment impact assessment or community consultation in allowing for the event.

So while the cause may be noble, the means appears to be ignoble.

A Bushcare Volunteer’s Concerns about Environmental Damage

.

The following correspondence last month is between a concerned Blue Mountains Bushcare volunteer and Trek for Timor.  Names have been omitted out of respect for privacy.

.

9th Sep (Bushcare Volunteer):

.

Dear Trek For Timor,

“As a local resident, environmentalist and Bushcare participant/bushland restorer, I am very concerned that the ‘Trek for Timor’ event will be passing through an environmentally sensitive area.  Of great concern is the proposed creek crossing from Peckmans Road to the lower Katoomba Sports Oval. This area is (and has been for many years) a focus of environmental restoration.

I respectfully consider that three hundred and fifty ‘Trek for Timor’ participants crossing here would severely degrade the creek and its surrounds. Other crossings are also degrading the creek further downstream.

I consider the event can still take place but request that it by-pass the area of concern. I suggest it instead take a route that enters the adjacent top sports oval from Cliff Dr.

I look forward to your reply and understanding.”

Regards,

(Bushcare Volunteer)

.

9th Sep (Trek for Timor):

.

“Good Morning (Bushcare Volunteer),

I have been forwarded your email regarding your concerns raised about Trek for Timor route passing through the section near the lower Katoomba Falls Oval.  I am the volunteer in charge of the route for this event and and thank you for letting us know your concerns.

You will of course be aware that any event held in the Blue Mountains area is subject to strict guidelines and requirements from Council.

Unfortunately the event is now only a few days away and it would be very difficult to change the route at such a late stage.  There were also additional reasons due to traffic concerns and safety as to why the route was put around through the back of the reserve.  Additionally, there are only 150 walkers who are registered to walk through this area, as the other walkers will be either stopping at the 5km or 13km checkpoints.

I would, however, be very interested to meet with you on site sometime this week to see if there is some signage we can use to draw the participants attention to care being taken in that area.  Also, although we may be constrained in being able to change the route for this Saturday’s event, the event may be held again in 2014 and we would like to know your concerns so we can ensure that we avoid any environmentally sensitive areas, and have the time to plan any such re-route for that year.

Please let me know if we can meet at the reserve sometime this week (lunch times or prior to 9am would suit me best).

Thanks,

(Trek for Timor)”

.

10th Sep (Bushcare Volunteer):

.

Hello (Trek for Timor),

“Thanks for your reply of 10 Sept 2012 below to my email of 9 Sept 2012 further below.

I respond as follows:

1. Thank you for your offer but signage will not prevent degradation. I consider that 150 participants will degrade the sensitive creek where proposed to be crossed. The only way to prevent the degradation is to by-pass the area as suggested at point 3 below.

2.   The Council has neither informed the local community nor environmental groups of the proposed event. Consequently, there has been no local input.

3.   I consider the traffic and safety concerns can be readily addressed given the traffic and safety issues along Oak St should already exist.  I note that instead of turning left into Peckmans Rd, the route could easily continue for approximately 200 metres along Oak St. without any further road crossings before entering the top sports oval. The participants could then walk around the perimeter of the top and lower sports ovals to maintain the required distances of the event.

4.   Given the small variation, I believe the route can be changed within five days before the event commences this Saturday.

5.   Respectfully, the event could be seen as environmentally unsustainable should it proceed as currently planned.

I look forward to your reply and trust the event will now be re-routed.”

Regards,
(Bushcare Volunteer)

11th Sep (Trek for Timor):

.

Dear (Bushcare Volunteer)

“Our committee has  given full consideration to your suggestion and has sought Council’s advice on your request to reroute the trek. Both Council and the Trek for Timor organisers have safety concerns regarding your suggested alternative route, especially the very busy intersection of Kamilaroi Rd, Katoomba Falls Rd & Cliff Drive.

As we  are sure you will agree, the safety of the trekkers is paramount.

The Environment Sustainability Officer of Council has also advised us that he considers the trek will have little or no impact on the crossing we will be using.

Having considered your request, taking advice from Council and following our committee discussions we have decided to continue with the course as planned. Our offer of signage advising the trekkers to take care when crossing the creek still stands.

Thank you for raising your concerns with us. Please direct all future correspondence to BMCC’s Environmental Sustainability Section.”

Regards,
T4TBM Organising Committee

(Trek for Timor)

.

14 Sep (Bushcare Volunteer):

.

Dear (Trek for Timor),

Thank you for your reply of 11 September 2012 below to my email of 10 September 2012 further below.

I respond as follows:

1. I think it is inappropriate for me to only direct my concerns to Blue Mountains City Council especially when the “Trek for Timor Blue Mountains Organising Committee” has organised the event. I also consider it necessary for me to respond to your replies of 10 and 11 September 2012 to dispel some misconceptions.

2. I wish to remind you that there has been no local input given Blue Mountains City Council has neither informed the local community nor environmental groups of the proposed event. Please provide me with the name of the Council’s “Environment Sustainability Officer” whom you contacted and their correct title, as I am only aware of the manager and administration and education officers carrying this title.

3. Once again, thank you for your offer but signage “advising the trekkers to take care when crossing the creek” will not prevent its degradation. The only way to prevent the degradation is to by-pass the area as suggested at point 6 below and point 3 in my email of 10 September 2012 further below.

4. I consider that environmental qualifications are not needed to understand that 150 “trekkers” crossing a muddy creek will damage it and the riparian vegetation. As such, I consider that any alternative unfounded view could be seen as deceptive and misleading.

5. You state that “Both Council and the Trek for Timor organisers have safety concerns regarding your suggested alternative route, especially the very busy intersection of Kamilaroi Rd, Katoomba Falls Rd & Cliff Drive.” Yet your replies of 10 and 11 September 2012 neither alerted me that the route would be crossing Katoomba Falls Rd during the very busy weekend traffic from the Katoomba Sports Oval towards the Katoomba Falls Kiosk for the 25 km and 45 km events, as is indicated on your web site. I also note that the detour I suggested on 10 September 2012 and at point 6 below passes through this location without any extra road crossings and so does not create any additional safety concerns and thus required additional resources that should already be addressed. Accordingly, I consider that it would be fair for me to say (and anyone reading this email) that all replies (and alleged replies) received by me from those involved in the “Trek for Timor” event to date are unfounded, perhaps misleading and deceptive.

6. I consider that there is ample time to change the route so that the participants can enter Katoomba Sports Oval off Cliff Drive. Traffic marshals and signs could be easily moved from Peckmans Rd to Kamillaroi Rd and Cliff Dr, as well as informing participants of the detour at the start of the event. Unlike the planned route, I note the detour does not require the participants to cross Katoomba Falls Rd.

7. Should the event continue to cross the creek adjacent to Peckmans Rd as planned and any other creeks in this area, it appears to me that the “Trek for Timor Blue Mountains Organising Committee” does not wish to acknowledge and address the concerns of local residents and environmentalists who have cared many years for this sensitive area.

I look forward to your reply and trust the ‘Trek for Timor Blue Mountains Organising Committee’ will reconsider re-routing the event.”

Regards,
(Bushcare Volunteer)

23 Sep (Bushcare Volunteer):

Dear ‘Trek for Timor Blue Mountains Organising Committee’,

Further to my email of 14 September 2012, I note the following:

1. The ‘Trek for Timor Blue Mountains Organising Committee’ did not reply to my email of 14 September 2012 below.

2. The ‘Trek for Timor’ event was not re-routed but instead went ahead on 15 September 2012 and crossed the creek adjacent to Peckmans Road despite ongoing prior concerns, requests, a suggested feasible alternative route and opportunities not to do so.

3. A ‘Trek for Timor’ notice erected next to the entrance of upper Katoomba Falls Sports Oval acknowledged that “there will be a high volume of walkers” participating in the “Trek for Timor” event.

4.  Despite the ‘Trek for Timor’ event being advertised as a “walking” event, a number of participants were instead seen running the event, including at the creek crossing. These participants were also strongly encouraged to do so by ‘Trek for Timor’ marshals.

5.  As indicated on the ‘Trek for Timor’ web site, the ‘Trek for Timor Blue Mountains Organising Committee’ (together with Blue Mountains City Council) was prepared to re-route participants up Cliff Drive and onto Birdwood Avenue in the event that Prince Henry Cliff Walk was closed during the event yet did not want to re-route the event along a safer stretch of road to prevent a creek crossing. I note locals consider Cliff Drive and Birdwood Avenue to be very dangerous roads for pedestrian use due to the number of sharp bends, the steep slope, the lack of safe pedestrian access and the speed and size of vehicles that utilise these roads.

Consequently, I consider the ‘Trek for Timor’ event has caused environmental damage to the creek adjacent to Peckmans Road and its riparian vegetation. In addition, I consider that the ‘Trek for Timor Blue Mountains Organising Committee’ disregards local community concerns including the community’s efforts in protecting and restoring environmentally sensitive areas for more than twenty years.

I trust future “Trek for Timor” events will no longer take place in Upper Kedumba River Valley.

Yours faithfully,

(Bushcare Volunteer)

Editorial Comments:

.

[1]  There appears to have been no community consultation process facilitated by either the Blue Mountains Council or Trek for Timor – genuine, fair, transparent or otherwise.  Local interested stakeholders such as local Bushcare Groups appeared to have not been consulted in respect to the event itself and the route chosen.    Bushcare Volunteer:  “there has been no local input given Blue Mountains City Council has neither informed the local community nor environmental groups of the proposed event.“

.

[2]  No environmental assessment appears to have been conducted by the Blue Mountain Council or by the local New South Wales National Parks and Wildlife Service.  Trek For Timor’s claim of there being “strict guidelines and requirements from Council” are not publicly available.    What are the “strict guidelines and requirements from Council”, if any?

.

[3]  The decision by Blue Mountains Council to allow the course route to traverse a sensitive creek watercourse that is under remediation as a Bushcare site is contrary to the ecological restoration and native habitat conservation objectives of Bushcare.   The creek site is within 200 metres upstream of Katoomba Falls and the Greater Blue Mountains World Heritage Area.   There appear to be no control limits on the numbers of participants and their support crews.

.

[4]  The cumulative impacts of tramping and soiling by the Trek for Timor and other similar running events upon the local natural environment appear to have not been environmentally assessed.  Any such assessment outcomes by Council’s Environment Sustainability Officer is not readily available on either the Blue Mountains Council website or on the Trek for Timor website.

Similar running events through the natural bushland of the Blue Mountains that have been approved by Blue Mountains Council in recent years are:

• Running Wild NSW  ^http://www.runningwildnsw.com/

 

‘Running Wild is keen to provide NSW runners with opportunities to regularly run on trails and where better than in the Blue Mountains National Park. The park covers a huge area and is already known for great races such as the Woodford to Glenbrook, the Six Foot Track and The North Face 100, but there are many other excellent trails out there, just waiting to be run. Our vision is to bring new and exciting trail races to all runners, which is also good for us, as it gives the committee a really good excuse to get out on the trails and run more, to find even better trails to share.”

[5]   The current trend of adventure recreation and adventure tourism have not been adequately assessed by the government custodians of the environmentally sensitive and ecologically important vegetation communities in which these activities have been allowed.  Adventure Tourism is an ongoing threat to the integrity and health of native habitat.

Blue Mountains Swamp

A ‘hanging swamp‘ – hanging on a steep slope

.

The Blue Mountains National Park is one of seven national parks which collectively comprise a million hectares of the Greater Blue Mountains Area, which since 2000 has been listed as a UNESCO World Heritage Site.   This area is protected internationally for (1) its outstanding examples representing significant on-going ecological and biological processes in the evolution and development of terrestrial, fresh water, coastal and marine ecosystems and communities of plants and animals and (2) contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation.      [Read More about ^The Greater Blue Mountains World Heritage values]

.

Since 12th May 2005,  ‘Temperate Highland Peat Swamps on Sandstone‘ have been recognised as an important and rare ecological community listed as Endangered under the Australian Environment Protection and Biodiversity Conservation Act 1999, as well as within New South Wales under the Threatened Species Conservation Act 1995 (NSW) (TSC Act).

So naturally, one would expect such swamps to be identified, mapped and ecologically protected – one would expect.  .

These swamps occur naturally in very few places on the planet, as shown (in red) in the following distribution map within south eastern Australia:

.Temperate Highland Peat Swamps on Sandstone – Global Distribution Map

.

Blue Mountains Swamps are included as part of the Temperate Highland Peat Swamps on Sandstone.   These are the top two red areas in the above map.

The Blue Mountains west of Sydney are Triassic sandstone plateaux.  Blue Mountain Swamps occur in shallow, low-sloping, often narrow headwater valleys (Keith and Benson 1988; Benson and Keith 1990), on long gentle open drainage lines in the lowest foot slopes, low-lying broad valley floors and alluvial flats (Department of Environment and Conservation 2006), and in gully heads, open depressions on ridgetops and steep valley sides associated with semi-permanent water seepage (Holland et al. 1992; Blue Mountains City Council 2005; Department of Environment and Conservation 2006).

.

Most of these swamps are situated within the Greater Blue Mountains Area and so are ecologically protected, but many are not.  Many Blue Mountains Swamps are situated just outside on the fringe lands.  Those fringe lands lie on the bush interface with human residential settlement and despite their environmental protection on paper are at risk of being bulldozed for housing development.   Such threats from development are referred to as ‘edge effects‘.   These swamps are on the edge of housing development, or put the more chronological way, housing development is being allowed to encroach upon the edge of these swamps that were there first.      Other Blue Mountains Swamps such as those up on Newnes Plateau are at risk of being bulldozed and drained for mining.

According to the Blue Mountains Council, there are less than 3,000 hectares of Blue Mountains Swamp in existence. As they predominantly comprise many small areas, they are very susceptible to edge effects.    As the urban footprint expands to the edges of the plateau, the swamps are coming under ever increasing pressure.

.

• Clearing for urban development
• Urban runoff – sediment deposition, tunnelling and channelisation from stormwater discharges
• Bushfire (both ‘wild’ and ‘hazard’ reduction)
• Weed invasion
• Nutrient enrichment (urban runoff)
• Mowing
• Grazing
• Water extraction (bores, tapping natural springs and building dams)

..

Blue Mountains Swamps – substrate characteristics

.

Blue Mountains Swamps are characterised by the constant presence of groundwater seeping along the top of impermeable claystone layers in the sandstone and reaches the surface where the claystone protrudes (Keith and Benson 1988; Holland et al. 1992; Blue Mountains City Council 2005).

The substrate tends to be a shallow black to grey coloured acid, peaty, loamy sandy soil with organic matter and are poorly drained and so tend to be either constantly or intermittently water logged (Hope and Southern 1983; Keith and Benson 1988; Benson and Keith 1990; Stricker and Brown 1994; Stricker and Wall 1994; Winning and Brown 1994; Stricker and Stroinovsky 1995; Benson and McDougall 1997; Whinam and Chilcott 2002; Department of Environment and Conservation 2006).

Blue Mountains Swamp on Newnes Plateau

 

The swamps naturally trap sediment and disperse rain water over a wide area and protect floors of headwater valleys from erosion.  They vary in structure and species composition according to geology, topographic location, depth of the water table, extent and duration of water logging and bushfire frequency.

.

Blue Mountains Swamps – vegetation variation

.

The structure of Blue Mountains Swamp vegetation varies from open shrubland to closed heath or open heath (dominated by shrub species but with a sedge and graminoid understorey and occasionally with scattered low trees) to sedgeland and closed sedgeland.   The Greater Blue Mountains World Heritage Area ids listed for its outstanding natural values, a major component of which is the high number of eucalypt species and eucalypt-dominated communities.  These can be found in a great variety of plant communities including within and upslope of Blue Mountains Swamps.

Topographic location, hydrology and soils significantly influence the dominant species composition.   Structure of the vegetation varies from closed heath or scrub to open heath to closed sedgeland or fernland.   The common cross-feature with all types is the presence of frequently waterlogged soil.

So what differentiates a Blue Mountains Swamp?

.

What is common across the above varying substrate and vegetation characteristics, that differentiates a Blue Mountains Swamp from other vegetation communities are the following attributes:

1. Situated on the Narrabeen Sandstone plateaux across the Blue Mountains region
2. Underlying sandstone, ironstone and claystone bedrock forming a horizontal impermeable layer
3. Ancient peaty sandy soil with organic matter that is poorly drained
4. Presence of groundwater
5. Constantly or intermediately waterlogged soil
6. Locally native vegetation that thrives in such waterlogged soils

.

Q:  But where do the spatial limits of a Blue Mountains Swamp begin and end?  Are Blue Mountains Swamps dependent upon the health of adjoining vegetation communities, particularly of those upstream.

A:  Probably, but who knows and who is researching Blue Mountains Swamps?

 

Q:  Is it the physical characteristics that differentiate a Blue Mountains Swamp from other less significant vegetation communities or is it our selective attitudes that decide whether to protect it or condemn it?

.

The headwaters of Katoomba Creek are forked from four upland gullies, one which has been dammed for water reservoir (Cascade Reservoir), and another starts near Twynam Street which forms the outer settlement area of Katoomba.  It is just three kilometres upstream from the World Heritage Area – the boundary of which is rather arbitrary and should be here at the precious headwaters.

Yet despite the substrate and vegetation characteristics of the creek headwaters suiting those of a Blue Mountains Swamp, Blue Mountains Council’s chief housing development manager, Paul Weston, Executive Principal, Building & Construction Services on 13th February 2012 deemed that “the vegetation community across the site is consistent with the Eucalyptus oreades Open Forest community, and known variations of that community, and is not a hanging swamp.”

“The inspections confirmed that some basic features common to hanging swamps are present on the land, such as steep slopes and groundwater seepage which supports the occurrence of the fern species Pouched Coral Fern (Gleichenia dicarpa), which is also found in swamps.  However, the absence of many typical Blue Mountains Swamp species, the presence of a prominent tree canopy, the absence of peat formation and the co-existence of the ferns with established and emerging sclerophyll shrub species, make this community inconsistent with that of the Blue Mountains Swamp Community.”

Furthermore, while the sheltered south easterly aspect, steep slope, the underlying geology and locally moist conditions provide a niche within the forested E. oreades- E. radiata – E. piperita community for ferns and other species to flourish in the wet conditions, the area does not support the usual suite of Blue Mountains swamp sedges, ground layer and shrub vegetation, nor the development of peat, nor is it wet enough to prevent the co-existence of other drier sclerophyll forest understory and canopy species in this vicinity.

This pristine vegetation community lies wholly within the riparian zone of the headwaters of Katoomba Creek (just metres away from the above photo).  The underlying substrate is sandstone, ironstone and claystone bedrock forming a horizontal impermeable layer.  The soil is ancient peaty sandy soil with organic matter that is poorly drained.  It has constant groundwater causing waterlogged soil.  The vegetation is a carpet of Pouched Coral Ferns, with a large cluster of King Ferns.  It has Soft Twig Rush (Baumea rubiginosa), its Lepidosperma limicola (sedge grass in foreground).    The tree canopy is Eucalyptus oreades which is common across Blue Mountains Swamps found at creek headwaters, but endemic only around Katoomba.

Is this more Swamp Selective Bias?

Indeed, the Blue Mountains Council ecological mapping assigned this site as a dry sclerophyll  Eucalyptus piperita/ Eucalyptus sieberi forest.  Woops.

The Council judgment letter stated that this site is zoned under Local Environmental Plan (LEP) 1991 as Residential Bushland Conservation.  But in fact, 80% of the site is zoned as a ‘Protected Area – Environmental Constraint‘  (see below extract).  Woops.

.

The ‘Environmental Constraint Area‘ zoning under Local Enviropnment Plan 1991 for 121 Twynam Street (perimeter highlighted)

covers 80% of the site from the street frontage.

.

LEP 1991 Protected Areas Objectives:   Clause 7.2 Environmental Constraint Area

.

(a) To protect environmentally sensitive land and areas of high scenic value in the City  (Ed: not that any reasonable person could possibly deem the Blue Mountains to be a ‘city’).
(b) To provide a buffer around areas of ecological significance.  (Ed: Such as a pristine Blue Mountains Swamp)
(c) To restrict development on land that is inappropriate by reason of its physical characteristics or bushfire risk.  (Ed: the site is Bushfire Risk Category 1)

.

121 Twynam Street is zoned a Category 1 Bushfire Risk

.

The Slope of the site exceeds 33% grade, which exceeds the limits for the Council’s development criteria

.

LEP 1991 Clause 11.3  ‘Environmental Constraint Area’

.

“The Council shall not consent to development in a Protected Area – Environmental Constraint Area, unless it is satisfied, by means of a detailed environmental assessment, that the development complies with the objectives of the Protected Area that are relevant to the development and will comply with the Development Criteria in clause 10 that are relevant to the development.”

 

Council Judgment:

.

 “In conclusion it is considered that the proposed dwelling and driveway have been designed and located to ensure that the development will not have a significant adverse environmental impact and is suitable for the site.”

Ed:  So is this judgment and the process one of selective blindness, ignoring rules, hypocrisy, incompetence, or worse?   In the case of Katoomba Creek Swamp, the decision is not to save this particular Blue Mountains Swamp, but to bulldoze it.
