Hart Road Wetland

These images demonstrate human-initiated and managed successional landscape transformation from barren

and denuded agricultural pasture in 2008 to a restoring landscape in 2014—part of the wider change facilitated

by this ecological restoration and wetlands project. The photographs show the landscape in (top to bottom):

April 2008, October 2009, July 2011 and November 2014.

Hart Road Wetland, City of Onkaparinga, Adelaide, Australia, 2003–2008

The 642 acre (260ha) Hart Road Wetlands lie on the northern boundary of the Aldinga Scrub Conservation Park,

which is the last significant vestige of indigenous coastal ecosystem on the Adelaide metropolitan coastline.

Land around the site had been cleared and drained for cropping and grazing except for the Conservation Park.

The wetlands were constructed by the City of Onkaparinga in 2007 as part of the 2003 council designed

Aldinga Beach Drainage Scheme. Agricultural drainage lines (some eroded into deep channels) did not allow

for ponding of water and aquifer recharge, resulting in remnant vegetation in the Conservation Park suffering.

Hart Road Wetlands are designed to mitigate stormwater runoff from existing suburbs, provide water quality

benefits and retention requirements for new adjacent residential development, and recharge groundwater.

Stormwater is directed into a series of varied depth basins where it is filtered and injected into the aquifer for

storage and recovery (ASR). This forms part of a wider pressurized recycled water network in the municipality,

distributed to parks, reserves, sports fields and schools. An indigenous plant palette replicating pre-European

vegetation systems increases habitat for remnant local wildlife, while a network of paths offer recreational

amenities. Since establishment, adjoining areas have benefitted from the increased water, with Cliff’s

Waterhole being refilled for the first time in recent years.

두번째는 미국의 Mill River Park and Greenway

Mill River Park and Greenway, OLIN, Stamford, Connecticut, USA, 2005–2013

The area’s first Puritan settlers renamed the then meandering Rippowam River (inhabited by the Algonquin

people) Mill River in 1642, damming it to create the town’s original gristmill. Intense industry led to severe

degradation—concrete walls inhibited access, compromising ecological systems, while excessive siltation,

trash, and debris collected behind the dam, resulting in invasive aquatic plants and blooming algae choking the river.

In 2005, OLIN led a team of ecologists and civil engineers to restore the river and habitats and establish an

economically viable, maintainable park. The resulting 14 acre (5.6ha) community greenspace showcases local

flora and fauna, restores natural ecological systems, invigorates urban redevelopment, and celebrates

community through diverse programming.

2.7a shows the transition before, during and after restoration.
