Here is some info on how to

Enhance connectivity in the landscape

'Connectivity' relates to the capacity of a species to move through the landscape between suitable habitats. It is influenced by physical features such as the distance to move, presence of connecting habitats, and extent of barriers to movement. Connectivity is also influenced by behavioural features for a species, such as the size of its regular movements, ability to tolerate altered habitats, and response to land uses in the surrounding environment. A landscape with high connectivity is one in which a particular species can move readily between areas of its habitat. Conversely, a landscape with low connectivity is one in which a species has difficulty moving between habitats, so that populations are largely isolated.

Achieve connectivity by the different habitat configurations
Animal species have differing levels of mobility, differing habitat requirements and differing responses to habitat change.

• Corridors of favoured habitat that form a continuous link between two vegetation patches are needed by wildlife species that cannot live in, or have difficulty moving through, the surrounding developed land.
• A series of one or more stepping stones of favoured habitat may be sufficient to allow movements by species that have limited tolerance of surrounding developed land.
• A mosaic of natural and modified vegetation (such as scattered trees in paddocks) may be adequate for species that are tolerant of land uses in the surrounding environment.

Revegetation activities have great potential for promoting landscape connectivity by establishing or enhancing stepping stones and corridors. However, it is critical that the planned revegetation is actually capable of serving in this way. A single line of trees, for example, has little chance of being an effective corridor for any but a few generalist species. A useful goal is to aim for a linear strip from 20 - 50m in width, or wider where possible.

+ Recognise different kinds of movements through links
Links such as corridors or stepping stones may be used by wildlife in several ways:

• single direct movements by animals using corridors or stepping stones as a pathway;
• movements by an individual with one or more 'pauses' along the way;
• combined movements of a number of animals living within the link, resulting in overall movement and interchange between two habitats but not necessarily by a single individual.

The type and quality of revegetation needed to support these movements differs. For single direct movements, animals may require only shelter or refuge; whereas to live within a link animals need food, shelter and breeding sites. The most effective way to enhance connectivity is to provide links of sufficient quality for animals to be able to live within them.
