Growth Trends And Water Use Efficiency Of Pinus Pinaster Ait. In Response To Historical Climate And Groundwater Trends On The Gnangara Mound, Western Australia, Lindsay Bourke
Theses : Honours
In Western Australia, groundwater accounts for about 57% of Perth's water supply. The majority of this is from the Gnangara Mound, the largest superficial aquifer on the Swan Coastal Plain. Prior to the mid 1970's groundwater of the superficial aquifer reached a semi-steady state, however since this period levels have been steadily falling. This decline coincides with a dramatic change in Perth's climate, groundwater abstraction and maturation of pine plantations. The influence of pine plantations upon groundwater recharge is well understood, however there is paucity of information about groundwater use, in particular whether pines directly access shallow groundwater resources.
