1

Integrated farming

An approach to farming combining traditional methods with modern technology to achieve higher levels of productivity without increasing the environmental impact

2

Ecological footprints

A measure of how much productive land (global hectares) is required to produced goods and services send dispose of the waste necessary to support a particular lifestyle

3

Impact of conservation

Boardwalks - Lilly Pilly Gully - Wilsons Prom

pros
- reducing impact on env, not walking over native species.
-reduce erosion

Negs
- remove some of the existing env before construction.
- building permanent structures

4

Impacts of recreation

Surfing - squeaky beach - Wilsons prom

Pros
- education
- fun/ adventure

Negs
- sand dune erosion
- damage to primary sand dune, flora species

5

Community based approaches

- clean up Australia Day
- T4N

6

Trust For Nature

Is a non profit organisation that has the objective of reducing environmental impacts through working with private land owners.

7

How T4N works

Trust for nature manages permanent, legally binding agreements placed on A properties title to ensure that the native vegetation on the property is protected forever. The agreement is voluntary, and is negotiated between themselves and the land owner.

8

T4N covenants

Conservation covenants remain one of the most effective ways to protect native plants and wildlife on private land. The covenant remains attached to the title, even if it is sold.

CC are backed by state legislation through Victorian conservation trust act 1972. They currently have more than 1115 conservation covenants.

9

Code of conduct

A code of conduct is a set of rules in the ways we must act when in the outdoors and participating in the environment.

10

Codes of conduct kayaking

- wear helmet if participating on moving water
- carry spare paddles on all river trips.
- minimal impact/ leave no trace
- take boats in and out at designated entry points, rather than disturb coastal dune areas.

11

Direct impacts

Are those caused by the action and occur at the same time and place, usually observable. Eg, snow making machinery.

12

Indirect impacts

Are those that are caused by the action, but not immediately. They happen before an event, or later in time but are still reasonably foreseeable. Eg, equipment manufacture or transport.

13

Snow making machinery
Direct & indirect impacts

Direct:
- depletion of water sources, negatively impacts flora and fauna which depend on water source.
- land clearing required for trucks.

Indirect:
- snow making generally occurs when water levels are low, meaning water has to be transported to the mountains. This transportation uses a lot of energy burning fuel which pollutes the environment.
- increased energy consumption of the mountain from diesel generators as the snow season is extended.

14

Urbanisation

Refers to the development and physical growth of towns and cities.
The process meaning the natural envs are impacted (suffer) due to the need for extra land, for the construction of houses, and industry.

15

Major threats

- land degradation
- extinction of species
- habitat loss
- population increase

16

PROS AND CONS OF URBANISATION

Pros
-education, Edithvale wetlands education centre.
Community education
Bird species

Environments
Protection strategies

- recognition of parks and reserves system, importance

NEGS
- land clearing
- removal of habitats/ ecosystems
- decreased biodiversity levels
- water pollution
