"This column is dedicated to the proposition that Canada (and indeed the world) is in a crisis situation and that fundamental social change is required to remedy this situation." - The First Column, Lambda November 2, 1971 This blog is inspired by my column of the same name in the Laurentian University Newspaper, Lambda, from 1971-1973. The title refers to the concept of subverting the system from within. To read key excerpts from those columns read the first few posts in this blog.

Yes, I've decided to become a twit, or a twitterer or whatever you call one who tweets. I've been watching Twitter for awhile and decided to try it. Like most forms of Internet technology I think it is misused more than it is well used, particularly as another way for celebrities to say "I'm more popular than everyone else - I have more friends without lives of their own following me than you do."
One of the things I think Twitter is really useful for for is live blogging - allowing 'citizen journalists to cover events live just like the mainstream media as well as for disseminating in formation on political/social/environmental campaigns and events.
I will probably be using it primarily to let followers know when I have updated either of my blogs - The Fifth Column or Richard' GPS Trail Maps and occasionally to draw followers attention to other blog posts that I am really impressed with.
So why now. Well I just broke my arm a week ago in a mountain biking accident and will be unable to bike for 6 to 8 weeks and somewhat limited in what I can do with just one useful arm and hand so I'm probably going to be spending more time at the computer for awhile.
You can find me on Twitter at Richard W. Woodley (the5thColumnist) on Twitter. You do not have to have a Twitter account to access this page and read my twits.

Bring your friends and family! Spread the word -- please pass this on to your networks. We've invited all municipal election candidates and we want to show them that people care about the South March Highlands and don't want the Terry Fox Drive Extension!
The Coalition to Protect South March Highlands is inviting everyone out to hike in this special and little-known area. This area is an overlooked gem of biodiversity within the City of Ottawa, on a par with Gatineau Park or Algonquin Park. It contains unique Canadian Shield geology, wildlife habitats and pristine forests, and is the most densely bio-diverse area in the City. It is home to more than 654 species, seventeen of which are species-at-risk, including the Blanding's Turtle, American Ginseng, Whip-poor-will and Butternut tree.
The Terry Fox Road Extension, currently under construction, and the planned residential development to follow, will devastate this ecologically significant and sensitive area. Come out and see why we're fighting so hard to protect it.
We will hike to Heron Pond, which is the largest body of water in the South March Highlands. We expect to see Blanding’s Turtles.
WHERE: The hike will leave at 1 pm from the intersection of 2nd Line and Klondike. There is ample parking along 2nd Line on both shoulders of the road. The walk will take place rain or shine, so dress accordingly and with proper footwear for hiking in the woods.
For more information contact Andrea Prazmowski at praz@magma.ca

It looks like the National Capital might have a new crusader against the hegemony of the automobile in our society.
Last month she was promoting turning "the national capital into a cycling role-model for Canada" and this month she wants Ottawa and Gatineau "to put public transit at the centre of their plans for city-building, today and over the next 50 years".
The position of head of the NCC has often been criticized for being an unelected and unaccountable position. However, as NCC CEO, Marie Lemay has shown more leadership than our elected Mayor "Photo-op" Larry ever has.

During Sunday's OMBA trail day there was some discussion about using natural materials, and particularly wood from around the trails in the South March Highlands, for trail projects such as bridges. I raised the issue that there may be a perception problem even if you use dead trees or trees that have come down during storms. Indeed there have been complaints of mountain bikers cutting down trees, though none of them have been confirmed and no evidence can be found of it happening. I suspect they may simply be based on people seeing trail crews going in with saws to cut down trees that have fallen over the trails during storms.
Then, yesterday, as I was riding along M-line, I remembered my earlier nature hike along the Terry Fox Drive Extension work with members of the Coalition to Save the South March Highlands where we saw the huge trees that had been cut down for the roadway, not to mention the cutting down of what may have been the oldest tree in Ottawa, an over 200 year old Maple. It seems that in Ottawa the City will spend hundreds of thousand in court costs to fight residents who want to remove trees that are damaging their foundations but when it comes to really significant trees and forests it gives the orders to clear cut them.
None of that can be undone but it got me thinking that maybe some of what has been cut can be salvaged for use in what remains of the conservation area, perhaps for trail work or for other uses.
If there is anything left of the over 200 year old Maple it should be preserved for use in a memorial to the City's greed (for free federal money) and willful environmental blindness. I would love to see the stump cut level with the roadway so drivers actually had to drive over the top of it to be reminded every time they drive the road of what was sacrificed for their precious highway.
Unless of course, the unthinkable happens, and they stop the madness.

OTTAWA — The NCC wants to inspire Canadians about the capital region by becoming a model for transportation, combining a network of cycling lanes and pathways across the downtown cores of Ottawa and Gatineau.As well as being a cyclist who rides the bike paths and roads in the National Capital Region, I am also a mountain biker. The National Capital Region, with it's Greenbelt and Gatineau Park, as well as the South March Highlands, has the potential, and the geography, to be a haven for mountain biking, and mountain biking should be included in any vision for cycling in the capital.
Marie Lemay says she hopes that “people would turn to us and say: How is it done in Ottawa? How is it done in our capital?”
...
Although the NCC has maintained recreational biking paths in the national capital region for 40 years, Lemay said she realized last summer the importance of moving beyond those paths to create a safe, integrated network of cycling lanes and pathways across the downtown cores of Ottawa and Gatineau.
The NCC, in it’s wisdom, has decided that mountain bikers should be second class citizens in the park. If they want to ride single track trails they are relegated to a small section of the park (Camp Fortune) run by a private operator where fees are charged. Meanwhile hikers and trail runners have free reign over all of the public trails in the park at no charge, including the wide trails designated for mountain biking.I would also at this time like to reference my three submissions on Mountain Biking in the Greenbelt to the NCC's Greenbelt Review. They provide more details on how the NCC can make the National Capital Region a haven for mountain biking.
I appreciate having the wide gravel trails to ride, they are fun, but mountain bikers, like serious hikers, love rough natural technical single track trails, which are a lot more environmentally friendly than widened gravel roads, which the NCC loves to build and call trails.
There are two arguments for keeping mountain bikers off single track trails - user conflicts and environmental damage. However, neither of these arguments holds up to scrutiny.
In various places, including the NCC’s own greenbelt (where bicycle use is against NCC regulations but the regulations are not enforced), hikers and bikers regularly share the trails with each other with few problems. I can personally attest to never having had a conflict with hikers on the greenbelt trails while riding them regularly (several times a week). I can also attest to hiking and mountain biking in the South March Highlands and always having other trail users treat me with respect, whether as a hiker or a biker.
As to the environmental impact, the overwhelming scientific evidence indicates that hikers and mountain bikers have equivalent impacts on trails. See, for example, the reviews done by the International Mountain Bicycling Association and the New Zealand Department of Conservation.
For more information on mountain biking see the International Mountain Bicycling Association (IMBA) website and the Ottawa Mountain Bike Association (OMBA) website.
...
The NCC has an opportunity to make the Gatineau Park an internationally acclaimed location for both road cycling and mountain biking. Let us see if they are up to the challenge.
3) OVERVIEW OF THE SPECIAL STUDY AREA (ADAPTED FROM BRUNTON 2000)The following is from Brunton's 2008 report, which discusses the impact of reducing the protected area of the South March Highlands to 35% of the original conservation area. Notice the use of terms like "ominously" and "disquieting".
The Special Study Area is situated at the southern end of the Precambrian Shield bedrock outcrop known as the Carp Hills which extends from Kanata northwestward to the Ottawa River in the Galetta area. This wetland-rich landform is unique in the City of Ottawa, constituting a 'island' of rugged, heavily-glaciated, rocky, Gatineau Hills-like habitat on the otherwise ±level, sedimentary lowlands. The end result is a landscape with severely limited agricultural potential and substantial challenges to residential/ commercial development. It has remained largely undeveloped, constituting one of the largest areas of continuous natural landscape in the City. The more or less original natural state coupled with a uniquely complex geology has resulted in the southern portion of the Carp Hills (the South March Highlands) supporting a diverse and significant natural biodiversity including Provincially and Regionally significant features and habitats (Brunton 1992a; 1992b; 1997).
The South March Highlands incorporates a number of watercourses and their watershed areas. The SSA incorporates catchment areas for the Carp River, Shirley’s Brook and Watts Creek. Most of the drainage in the SSA is westward down the Hazeldean Escarpment slope and into the Carp River. The northeastern corner of the area drains eastward, however, flowing into the south branch of Shirleys Brook. So too does the Watts Creek headwaters which commence immediately west of the First Line Road ROW in the southern half of the area and flows easterly through Kanata (‘Kizell Drain’), eventually discharging into the Ottawa River (Dillon Consulting 2002). Numerous small and/ or intermittent drainage channels occur in the many depressions and ravines occurring in this rugged landscape, all other eventually reaching the Carp River system.
The SSA (Figure 1) is part of the South March Highlands natural area which, in various configurations, has been identified as a candidate Provincially Significant Area of Natural and Scientific Interest (ANSI) (Brunton 1995), a High Value Natural Environment System Strategy (NESS) natural area (Ottawa-Carleton 1997; Brunton 1997) and Natural Environment Area-A and Natural Environment Area B (Ottawa-Carleton 1999). The significance of this area is reflected in the purchase of over 225 ha of natural landscape north of the railway for long-term ecological protection purposes by the former Region in 2000 (Figure 9). This ‘Regional Conservation Land’ area was enlarged by the City of Ottawa through the purchase of an additional 20 ha of adjacent natural landscape in 2002.
The SSA supports a rich diversity of native plant and animal species typical of superior examples of their respective habitats within the South March Highlands (Brunton 1992a). Some of these species are found within the Highlands only in or immediately adjacent to the SSA (see section 4.1, Significant native species, below). The mature upland deciduous forest habitat in the northern half of the study area contributes the greatest number of these representative and locally unique species (Brunton 1992b).
The SSA contains an extensive complex of common and rare habitats demonstrating a high degree of ecological integrity. Over 80% of this area supports Regionally rare vegetation types (Geomatics International 1995). A number of the nesting bird species present here and in the adjacent forested landscape to the east breed successfully only in extensive woodlands (Brunton 1992b; Muncaster 2002c). Habitat fragmentation is rare here, with the First Line Road ROW providing the only physical interruption crossing the length of the SSA.
A high level of natural biodiversity is identified as an important contributor to the identification of a Provincially Significant natural area (Ontario 1997). The contribution of the SSA to the ecological integrity of the larger South March Highlands natural area is an important element of the latter area’s overall significance and conservation value.
6.1 SIGNIFICANCE AND SENSITIVITY CONCLUSIONSAnd this is how he described, in his 2004 report, the impacts the KNL development and Terry Fox Road extension would have on the South March Highlands.
Remarkably, much of the native biodiversity identified in the 1991 - 1992 South March
Highlands inventories is retained within the 35% of the former South March Highlands conservation area presently designated as Conservation Forest. Approximately 94% of the native vascular plants of the larger area, for example, are (or were) found here. The fragility of this representation is underscored, however, by the wide variety and serious nature of present and increasing environmental stresses described in section 5. Impacts and ecological challenges (above).
It also bears repeating that the 41 Regionally Significant plant species now known from the Conservation Forest represent only 85% of the 48 such taxa known from the larger former conservation area and include none of the known Provincially Significant species of the South March Highlands. More ominously, perhaps, is the fact that 13 (27%) of Regionally Significant taxa, are either known or suspected to have been extirpated. Similarly, one known SARA-scheduled (Threatened) animal species, Blandings Turtle, has only been observed at the very western and northern edges of the Conservation Forest while another SARA-scheduled (Threatened) species, Golden-winged Warbler occurs at a site adjacent to a proposed arterial roadway corridor.
This evidently lower level of sustainability for the most vulnerable components of the native biodiversity of the Conservation Forest is particularly disquieting when future ecological isolation and the fragmentation of remaining natural landscapes is factored in. The proposed residential and transportation development within the South March Highlands (Terry Fox Road arterial, Second Line Road extension, etc.) undoubtedly markedly increase ecological stress on both the representative and exceptional natural features and functions of the Conservation Forest.
KNL lands:So where do we go from here.
Residential development is committed in the majority of the KNL lands between the First Line Road ROW and Goulbourn Forced Road. This has major implications for the ecological significance of both the SSA in particular and the South March Highlands in general. That includes a major reduction in the ecological corridor function presently active between the Regional Conservation Lands north of the Terry Fox Road ROW and the Trillium Woods Urban Natural Feature (UNF) within and immediately east of the Extended Study Area, along either side of Goulbourn Forced Road (Figure 9). It will also increase the edge effect impact of the Terry Fox Road ROW on the adjacent Regional Conservation Lands habitat. The KNL residential development area is transected by Kizell Pond Urban Natural Feature along Watts Creek.
The KNL development plan dramatically reduces the existing area of ecological connectivity between the SSA and other significant natural areas of the South March Highlands (Brunton 1992a; 1992b; 2000). The remaining UNF west of Goulbourn Forced Road constitutes about 100 ac (40 ha) of upland and wetland habitat (S. Murphy, pers. comm.). The Richardson Forest in Lot 6 will be particularly negatively effected, being completely isolated from comparable natural habitats to the north and east. As well, virtually all of the interior forest values of the Richardson Forest will be eliminated.
The loss of continuous forest habitat within the KNL lands north of Watts Creek in the West Block will have similar though less intense impacts on the northern portion of the SSA. The negative impact is lessened in that area by the existence of continuous natural habitat along the top and face of the Hazeldean Escarpment to the west of the SSA (Figures 2, 3, 4 and 5). Development of portions of the West Block on the KNL property will result in the loss of native biodiversity, a reduction in biological restoration and recruitment potential and the initiation of microclimatic changes. It will inevitably reduce the self-sustainability and overall ecological significance of the adjacent portion of the SSA. Without detailed on-site examination of the lands involved, however, it is difficult to quantify the loss of particular natural features.
4.8.3 Terry Fox Road extension impact
Dillon Consulting (2003) has established that construction of the proposed Terry Fox Road extension across the SSA will have a significant, negative ecological impact ....“Terry Fox Drive will form a barrier and break between the northern and southern portions of the presently continuous South March Highlands [natural] area”. Recognizing the importance of maintaining ecological connectivity across this barrier, Dillon Consulting. (2003) proposes a system of modified culverts and a major sub-roadway ecological passageway along the preferred roadway ROW to partially mitigate these loses.
As part of the recent discussions on the design of this road, an alternative route crossing the SSA and located slightly west of the preferred route (Dillon Consulting 2003) was suggested by a landowner. Dillon Consulting (2003) considered that the Balys & Associates alternative route would have “a higher impact on the environment (volume of rock knolls to be removed, and wetland impacted)”. In a later assessment of the natural environment implications of the Balys & Associates proposed route, it was suggested (Muncaster 2002b) that the degree of ecological disturbance along this alternative route for the crossing of the Hazeldean Escarpment and the SAA might be no greater or even somewhat reduced to that of the preferred Terry Fox Road ROW. That opinion, however, does not address the question of maintaining ecological connectivity across the roadway ROW other than to suggest that roadway development along either alternative will inevitably have some impact
Regardless of the route selected, it is clear that the extension of the Terry Fox Road arterial across the South March Highlands will constitute a major ecological challenge to the Provincially Significant values in and about the SSA and throughout a large segment of the South March Highlands. Major mitigation measures, as described above, will be required to at least reduce the losses of significant ecological value here.
OTTAWA — The Sierra Club Canada plans to start a national campaign this week attempting to stop the extension of Terry Fox Drive through the sensitive wetland habitat of the threatened Blanding’s turtle.As well, the Ottawa Forests and Greenspace Advisory Committee has recommended that the City halt construction on the Terry Fox Drive extension as reported in the Ottawa Citizen:
John Bennett, executive director of the Sierra Club of Canada, said the club will use its network to reach thousands of environmentally minded citizens, asking them to put pressure on municipal, provincial and federal politicians to stop the four-kilometre, $47.7-million roadway.
“It’s just a stupid, stupid plan. This is about greed and avarice and building more houses in a place that’s not appropriate,” Bennett said. “They don’t need to build this road through this wetland.
The Ottawa forests and greenspace advisory committee will ask city council to put the construction of the Terry Fox Drive Extension on hold and order a more thorough environmental review.This has rekindled interest in the preservation of the whole South March Highlands and led to local residents forming a Coalition to Protect the South March Highlands .
The committee passed a unanimous motion Monday night to ask the city to "immediately re-examine the demographic, transportational and economic rationale" for the project and to halt construction until an "in-depth ecological analysis is undertaken."
The request will come before the city's planning and environment committee, where it would need the endorsement of councillors before it could be voted on by City Council.

"If it takes civil disobedience," so be it, said Gerard. "We're not going to walk away from our jobs or our fathers' and grandfathers' jobs just because Vale says so. We'll fill every goddamned jail if that's what it takes."
Sudbury's Leo Gerard, as reported in The Sudbury Star:
United Steelworkers International President Leo Gerard is refusing to apologize for two controversial statements he has made during the 9 1/2-month strike by more than 3,000 Steelworkers.And it is about time my brothers and sisters in Sudbury said no to scabs doing their jobs.
Gerard will not say he is sorry for telling Sudbury in September that if business owners were not for striking Steelworkers, then they were against them.
Nor should anyone expect Gerard to say he regrets telling The Sudbury Star two weeks ago that USW will not allow Vale Inco to return to full production without its unionized production and maintenance workers.
"If it takes civil disobedience," so be it, said Gerard. "We're not going to walk away from our jobs or our fathers' and grandfathers' jobs just because Vale says so. We'll fill every goddamned jail if that's what it takes."
Gerard and his union have taken a good deal of heat for both of his remarks.
But the Steelworker who began with Inco's transportation department 45 years ago before rising to the top job with the international union said he is not taking either comment back.

Submission to the National Capital Commission Greenbelt Master Plan Review - Part 3
By Richard W. Woodley, environmentalist, hiker, mountain biker, snowshoer, cross
country skier, kayaker
(Please note: click on images to enlarge)
While this may seem like a my most radical proposal yet it follows naturally from what I have already written:
Getting people out into the environment, onto the lakes and rivers and into the forests builds healthy lifestyles, and healthy lifestyles improve our health and reduces our health care costs. This is important at a time when obesity, and childhood obesity in particular, is at epidemic levels. We need natural spaces and trails to teach our children the benefits and enjoyment that can be had in the great outdoors. The National Capital Region is fortunate that we have a population that celebrates healthy lifestyles and rises up to challenge those that want to take our natural spaces and trails away from us. Allowing mountain biking on the trails is one more way to encourage people to get out and enjoy nature.The Old Quarry are trails are particularly suited for young riders just starting out in mountain biking because they provide a wide range of difficulty from easy flat gravel trails to intermediate level rooty and rocky trails.
Young people need the type of challenges the outdoors can provide as an alternative to spending their time in a sedentary lifestyle centred on electronic devices, or other even worse, but seemingly exciting, activities like gangs and drugs. Youth can be attracted to these things by the very risks we want to protect them from. Outdoors activities such as rock climbing and mountain biking can provide exciting healthy risks that build character and a healthy body.
Mountain biking is the perfect activity to get young people active and out in the environment. It combines man and machine (or boy and machine) with a sense of adventure, all in a natural setting. The Greenbelt trails are the ideal location as many are closes to neighbourhoods and they have a wide variety of levels of riding difficulty and challenge.

After hearing from City staff and concerned residents, the Ottawa Forests and Greenspace Advisory Committee passed a unanimous motion to ask the City of Ottawa to immediately stop construction on the Terry Fox drive Extension through the South March Highland until an "in-depth ecological analysis is undertaken."
The Ottawa Citizen reported:
The Ottawa forests and greenspace advisory committee will ask city council to put the construction of the Terry Fox Drive Extension on hold and order a more thorough environmental review.At the meeting many residents expressed concerns about the project.
The committee passed a unanimous motion Monday night to ask the city to "immediately re-examine the demographic, transportational and economic rationale" for the project and to halt construction until an "in-depth ecological analysis is undertaken."
The request will come before the city's planning and environment committee, where it would need the endorsement of councillors before it could be voted on by City Council.
The $47.7-million Terry Fox Drive Extension is being built now to take advantage of $32 million in federal and provincial stimulus funding that runs out in March 2011.
The original plan to build the road dates back to a 1983 Ontario Municipal Board decision to expand Kanata's urban boundary into the South March Highlands, with the road marking the outside perimeter of development.
Once the road is built, 182 hectares of natural lands inside the arc of the road are expected to be bulldozed for housing.
But the highlands, a 895-hectare area of near-pristine woodlands and wetlands, have been identified by the province as a candidate for the designation of Area of Natural and Scientific Interest containing a complex of Provincially Significant wetlands.
It was standing room only at the city’s forest and greenspace advisory committee meeting Monday evening.Paul Renaud made a very interesting presentation on "Ottawa's Other Transportation System" in which he stated:
Marjorie Edwards, who lives on Old Carp Rd., said she fears the extension of Terry Fox Dr. will lead to more development and further destruction of sensitive environmental areas, with devastating consequences.
“The land is going to be developed. It started out as environmentally protected land from the province and it still is, but people seem to be able to find ways of circumventing it,” she said.
The road will encroach on habitat of about a half dozen species at risk, including the Blanding’s turtle and the western chorus frog. The project will also pass through four significant wetland areas and require about 10.5 hectares of clear cutting.
Judy Makin, who also lives in the area, shares Edwards’ concerns.
“Unbeknownst to most of the city of Ottawa, we’ve got a little Algonquin Park in our backyard and we’re putting a road through it. It’s not wise,” she said, comparing the South March Highlands to the protected provincial park.
Makin called on the advisory committee to recommend council issue an immediate stop work order to prevent any further construction. She also called for the establishment of a governing body, what she called the Ottawa Forest Keeper, to protect sensitive areas and deny destructive planning proposals.
“We cannot allow this roadway to provide the final doorway to even more destruction,” she said.
As you can see from this aerial photo, looking down from 50 km, we can see 3 major eco-corridors running in parallel to each other:I encourage you all to read the full text of his presentation in his blog Virtual Nonsense: Can You Still See The Forest?, and be sure to view the very interesting slides he presented.-Gatineau Park to the NorthEach of these eco-corridors plays a vital role in the transportation system of the National Capital:
-Constance Lake – Shirley’s Bay along the River
-South March Highlands to the South-They enable the transportation of animals, fish, and birds who live in and travel within themHow is it that City planners have been oblivious to the whole transportation picture?
-Who in turn carry native seeds, pollen, and other genetic material up and down these corridors
-This transportation of vital genetic material helps the City fight off the invasive species that our now threatening us as a result of the combination of irresponsible development and climate change
-These eco-corridors also help absorb the GHG emitted by the City’s other transportation system, turning these noxious fumes back into life-giving oxygen.
