Rory Carroll from the Gardian in the UK reports on 'LA's concrete storm drains conceal a living, breathing waterway that has rarely been explored – until now.'

He writes "The LA river will never compete with the Danube or Seine or Thames as an attraction for stressed city-dwellers. Nor will it inspire many poems or novels. It is too meagre, too hidden, to ever be fully part of the city. But advocates are on to something when they say it can transform perceptions of LA.

After passing a concrete bridge with graffiti-daubed arches and a shopping trolley half-buried in mud, we enter a wilderness that seems a world removed from the freeways and urban sprawl above. "We call this the Grand Canyon," says Wolfe, showing his flair for advertising, as we paddle through a mini-gorge 15ft tall. Nature slowly asserts itself. To our left are wild fig trees, descendants of those planted by the Indians, to our right potentially deadly ricin-producing plants. Further on, hallucinogenic gypsum weed. "Around the next bend is the Apocalypse Now bit," says Wolfe. We encounter "fish sticks": improvised traps made by unknown hands to trap carp, tilapia and other species. A discourse on how to make the traps is drowned out by a passenger jet roaring low overhead, briefly breaking the spell."

In his typically lively and thought provoking manner, George Monbiot  of the Guardian, stepped into the fray with his analysis of ecosystem services on Monday. Monbiot says 'The argument in favour of this approach is coherent and plausible. Business currently treats the natural world as if it is worth nothing. Pricing nature and incorporating that price into the cost of goods and services creates an economic incentive for its protection. It certainly appeals to both busines and the self-hating state. The Ecosystems Markets Task Force speaks of ''substantial potential growth in nature-related markets- in the order of billions of pounds globally'.

But he says 'it doesn't end there. Once a resource has been commodified, speculators and traders step in'.

Is Nature Deficit Disorder damaging Britain's children?

In a Radio 4 programme aired in April as part of the Nature series, Brett Westwood explored the growing use of coarse woody debris (CWD) in managing rivers.  

 ''According to Staffordshire Wildlife Trust, fish live in trees too'', says the BBC Radio 4. ''The Trust's biologists are using wood as a remarkably effective tool to change the depth and flow of streams and improve them for wildlife. They don't just stop at streams either: at the confluence of the Tame and Trent rivers, they've submerged entire willow trees in gravel islands in a project to widen the river channel.
