Objectives Climate Fore Dunes: Johnny Wang Second Dunes: Chen Guanda Kananook Creek: Erin Wilkie Seaford Wetlands: Stefanie Talarico References
environmental data for the following locations: fore dunes, second dunes, Kananook Creek, and Seaford Wetlands. F u r t h e r o u r u n d e r s t a n d i n g o f t h e environmental systems and attributes of the Seaford Beach area. Compare this data to expected results in the Background Research report. Discuss the differences and similarities between the four locations during the site visit.
climate Annual average rainfall of 719mm (Department of Sustainability and Environment 2012) During field visit strong Easterly winds were experienced
Site 1 â€“ Fore dunes
Location Eastings: 0335574 Northings: 5780942 Approx. 5-7m rise along Seaford Beach Directly behind the Fore Dunes and in front of the main road (Napean Highway) Landscape Covered by dense shrubs and grasses Stable dunes Similar to what was expected in background research report

Man-made boundary/fencing Tall grasses
Sand, sediments, shells, loose vegetation Beach/ocean
Human Impacts Timber
Peer Dune-fencing Community

Ecology The fore dune mainly consists of Coastal scrubs grasslands & Woodlands. Even though sand wouldn’t be the best type of soil for vegetation as it allows moisture to evaporate quickly. However, the shrubs and grasses on the dunes appear to be growing quite well because of the consistent rainfall during the year. Seagulls Insects living inside the shrubs Shells washed up by the waves
Salinity: 12,0400(µS/cm) Sea water will rise and fall with tides. Water on the beach sand will then either be absorbed by the soil or evaporated under sunlight. Rain water will be either absorbed by the roots of the shrubs/soil, or run downwards into the sea.
Geology Siliceous and calcareous sand. (Dune and beach deposits) – as indicated in the geological map The sand is also covered by lots of shells and branches that were possibly blown onto the beach from the shrubs at the top of the dunes

Site 2 â€“ Second Dunes
Source: Google Earth 2013
Location • Eastings: 335 602 • Northings: 5780 943 • Behind Foredunes, in front of Napean Highway Landscape • Marram grass and Sand Reed grass help stabilize sand • Wind and water movement in the sand • Open/vacant space. Pathways enable walking uses • Adjacent area used for recreational activities
Man-made boundary Grass and weeds Bush, climbing vegetation
Human Impacts Litter Fencing, just like the boundaries seen in Seaford Wetlands (site 4) Walkways for humans breaking up connections and natural pathways for the organisms
Hydrology Water draining into water table beneath, eventually getting to ocean Direct runoff from the land to the ocean Salinity:

Geology Sediment continually supplied through aeolian and fluvial processes. Expected from the background research done. pH of soil = 8 Texture: coarse sand Structure: granular, massive Sediments like sand (found on pathways; bottom left) and dirt (found in the other areas; bottom right)
Ecology Some insects observed during site visit Coastal birds like Seagulls were seen.
Site 3 â€“ Kananook Creek
Kananook Creek Train line Residential
Location Eastings: 335 797 Northings: 5780 1081 In Seaford area, parallel to the train tracks. Begins near Frankston Pier Landscape Land surrounding creek man made. Currently used as a park designed for families and dog walking Easy connection to the shops along the Napean Highway and residential areas
Source: Google Earth 2013
Shrubbery, bush (ground-mid stratum) Man-made attributes: -â€Ż Wooden path Additional plants -â€Ż Pavement/gravelled areas added by humans
Hydrology Creek connected to the ocean, begins just near Frankston Pier. Runs parallel with the Napean Highway and train tracks. Movement of water to and from the ocean Runs from northern Seaford. Water flow into the creek from the Eel Race Drain. Flows southward through Seaford Finally, flowing into Port Phillip (Duggan 2007) Salinity: 1,100 (µS/cm)

Human Impacts Addition of pavement and gravel grounds, less water being soaked into soils below surface Litter
Geology Seemed to be 2 distinct horizons. Top layer was dark brown, bottom layer was cream. Consisted of fine grains. Nature of the parent rock: clayish which was expected from the Background Research report.
Ecology Over 200 indigenous species Consists of trees (for example, Manna Gum), shrubs (Beard Heath), climbers and groundcovers (Clematis), and grasses (Kangaroo grass). Native birds, mammals, fish, aquatic creatures, reptiles, frogs, and insects. For example, Boobook Owl (image to the right) Many of these species, like the shrubbery, can also be seen in the Fore Dune and Second Dune areas.

Site 4 â€“ Seaford Wetlands
Location Eastings: 336 359 Northings: 5781 004 Behind residential houses Landscape Tall grass and swamps covering the landscape Man-made boundary
Source: Google Earth 2013
Trees Tall Grasses Swamp/ wetlands Boundaries
Short Grasses Weeds
Human Impacts Drainage Putting in electrical wiring Boundaries - prevent further human destruction in effort of conservation These conservation efforts are similarly present at all the other stops Currently a protected area
Hydrology Kananook Creek (stop 3) can subject the wetlands to tidal inflows Important in the regional drainage system to receive, retain and diverting storm water and surface run off (Lane et al. 2000) Drainage system leading to the wetlands has pollution. Negative human impact.
Geology Soil Profile: - Colour: black and very dark grey - Texture: silty loam, light clay, sandy loam - Structure: crumb, angular blocky, massive - pH: 3.8-4.1 which is mildly acidic (therefore no carbonates present)
Ecology The variety of aquatic animals in the wetlands and the fauna that habituates on the land around it. As in the background research report there were a variety of species present, including native species. For example the Eastern Yellow Robin.
