Ecosystem Management Study

Green Infrastructure Network

On April 18, 2011, Surrey City Council approved the Surrey Ecosystem Management Study (EMS) — a science-based study to identify and map the Green Infrastructure Network (GIN) in the City of Surrey. See COR R061 for details. 

It is the first phase of a broader initiative, originating from the City of Surrey’s Sustainability Charter (2008), to strategically manage environmentally significant lands and ecosystem values throughout the City.

The EMS provides the following:

• a mapping inventory of environmental features and ecological assets;
• a mapping inventory of vegetation types and structures;
• a delineation of a City-wide GIN into Ecosystem Hubs, Sites and Corridors;
• a GIN ecosystem valuation of Hubs and Corridors; and
• Management Strategies to support the GIN.


Green Infrastructure Network

The Ecosystem Management Study focuses on 4 main elements of Surrey’s landscape, which together form the City’s Natural Green Infrastructure Network (GIN):

  1. Hubs – large contiguous areas of complex ecological processes (at least 10 ha in size);
  2. Sites – smaller areas of natural vegetation (between 0.25 and 10 ha in sizes);
  3. Corridors –pathways that offer species and ecological process connection between hubs (100 meters wide);
  4. The Matrix – the rest of the land base with varying ecological value.

The second future phase of the project will include a detailed Biodiversity Conservation Strategy (BCS) and is expected to:

  • identify and quantify biodiversity and wildlife habitat resources in Surrey's GIN;
  • set objectives for species and populations of wildlife (targets);
  • determine habitat criteria such as corridor widths, sites and hubs to maintain biodiversity;
  • ensure target levels of biodiversity are conserved; and
  • provide indicators to monitor progress of the EMS.

Several Corporate Reports have gone forward to Council about the Ecosystem Management Study during its creation, and can be dowloaded below:
