  3. 3. Melbourne AirportUrban Landscape PlantingsIntroductionThe presence of bird populations surrounding Melbourne Airport is a potential hazard toaircraft. The occurrence of ‘birdstrike’ to planes can cause significant damage and havepotentially catastrophic outcomes. One method of minimising the possibility of birdstrike isto consider the vegetation that is planted in the vicinity of the airport.This booklet contains a list of plant species that have very few bird attracting qualities. Allspecies included are also suited to the environmental conditions of the Melbourne Airportand surrounding areas.Considering species selection when planting in proximity to the airport is an important factorin minimising the potential for birdstrike.This booklet contains a pictorial list of 17 tree, shrub or ground cover/climbing species.Botanical plant names listed with the suffix ‘spp’ is a reference to the entire genus. Forexample, all Hibbertia spp. exhibit similar qualities and are therefore suitable for plantingwithin the Melbourne Airport area.Plant details such as size and tolerances are included to aid in the decision of what to plantwhere. Any relevant cultivars have also been included where appropriate as well as theorigin of the species being either Exotic, Australian native, Victorian native or indigenous.Specifically, this means: Exotic – The plant has been introduced into Australia Australian Native – The plant is native to Australia Victorian Native – The plant occurs naturally in Victoria Indigenous – The plant occurs naturally within 30km of the surrounding airport area.Further suitable species are listed in the Melbourne Airport revised planting document.

  4. 4. Melbourne AirportUrban Landscape PlantingsA Guide to Using This BookletTolerancesPlant species display tolerances to environmental conditions due to adaptations to theirnatural environment. This is why indigenous plant species often perform better than exoticor native species from other parts of the country or the world.Where species have evolved in similar conditions to that of our own, some of the sametolerances are displayed.Melbourne’s environment is best described as ‘cool temperate’ and specific soil conditionsin the Melbourne Airport area are predominantly low nutrient clays with some smallerpockets of shallow sands on clay substrata. Species tolerances must therefore considerboth the above and below ground requirements of the plant.Drought ToleranceEstablishing plants in urban environments can be difficult. It is likely that all plants willrequire some level of irrigation in the first few years of establishment, and potentiallyintermittently for the rest of their life, dependant on specific water requirements. It should benoted however, that many plant species can become stressed in the absence of water andstill survive long periods of extended drought.Drought tolerance is described from “Poor” to “Very Good”.Plants with ‘Poor’ drought tolerance are likely to require intermittent to regularsupplementary irrigation throughout much of their life in order to maintain a healthy canopyof foliage and prevent premature death.Plants with ‘Moderate’ drought tolerance are likely to require summer irrigation throughperiods of drought.Plants with ‘Moderate to Good’ tolerance are likely to display signs of stress after relativelyshort periods of drought, though will tolerate extended periods of drought.Plants with ‘Good’ or ‘Very Good’ tolerance are not likely to require any supplementaryirrigation once established and tolerate long to very long periods of drought.

  5. 5. Melbourne AirportUrban Landscape PlantingsSun ToleranceThe level of sun exposure a plant receives can influence the growth rates and affect planthealth. Many species that are adapted to high light levels will not grow well in overshadowed locations. Conversely, some plant species cannot tolerate direct sunlight, andproduce symptoms such as scorched leaves when sun exposure is too great.A plant’s leaf design can often indicate its tolerance to sun. Glossy and often larger leavesare adapted to absorb as much sun as possible in limited light conditions, while small,sometimes hairy or glaucus (grey/green) leaves are adapted to minimise sun exposure. Figure 1: Dark, glossy leaves of the Rubber Tree Figure 2: Small, vertically aligned, leathery leaves can tolerate low light conditions of eucalypt trees are adapted to high sun exposure Page 5
  6. 6. Melbourne Airport Urban Landscape Plantings Compaction Tolerance Urban conditions are the most difficult conditions for plant growth. Soil environments are often highly disturbed in comparison to natural, undisturbed soils. The most inhibiting factor for root growth and therefore establishment is the effect of compaction. Soil compaction can be extremely detrimental because: • it changes soil conditions dramatically • the plant’s root system does not have enough time to adapt to the changed conditions. • It can lead to a decline in plant health and even death. Water infiltration into the soil horizon takes a lot longer. It also inhibits or prevents gas exchange between the roots and the atmosphere. Continuous pedestrian traffic, cars and trucks can all cause soil compaction, effectively starving roots in that area of water and oxygen. See Figures 3 and 4. The application of mulch can help alleviate to the problem of compaction and over time improve soil structure.Figure 3: Water movement and gas exchange under Figure 4: Water movement and gas exchange under normal conditions. changed conditions.
