It is jointly funded by the Queensland and Commonwealth Governments and is being carried out in three stages: Stage I - information gathering; Stage I1 - development of principles, policies and processes; and Stage III - implementation and review. The project dealt with in this report is a part of Stage I of CYPLUS. The main components of Stage I of CYPLUS consist of two data collection programs, the development of a Geographic Information System (GIs) and the establishment of processes for public participation. The data collection and collation work was conducted within two broad programs, the Natural Resources Analysis Program (NRAP) and the Land Use Program (LUP). The project reported on here forms part of one of these programs. The objectives of NRAP were to collect and interpret base data on the natural resources of Cape York Peninsula to provide input to: evaluation of the potential of those resources for a range of activities related to the use and management of land in line with economic, environmental and social values; and formulation of the land use policies, principles and processes of CYPLUS. Projects examining both physical and biological resources were included in NRAP together with Geographic Information System (GIs) projects. NRAP projects are listed in the following Table. Bedrock geological data - digitising and Vegetation mapping (NRO1) integration (NR05) Airborne geophysical survey (NR15) Marine plant (seagrasslmangrove) distribution (NRo6) Coastal environment geoscience survey Insect fauna survey (NR17) (NR14) Mineral resource inventory (NRM) Fish fauna survey (NR10) Water resource investigation (groundwater) Terrestrial vertebrate fauna survey (NR03) (NR16) Regolith terrain mapping (NR12) Wetland fauna survey (NR09) Physical ResourceIGIS Projects Biological Resource Projects I Land resource inventory (NR02) Flora data and modelling (NR18) Environmental region analysis (NR11) Fauna distribution modelling (NR19) CYPLUS data into NRIC database FINDAR Golden-shouldered parrot conservation (NR20) management (NR21) Queensland GIs dev%lopmentand maintenance (NR08) * These projects are accumulating and storing all Stage I data that is submitted in GIS compatible formats. Research priorities for the LUP were set through the public participation process with the objectives of: collecting information on a wide range of social, cultural, economic and environmental issues relevant to Cape York Peninsula; and highlighting interactions between people, land (resource use) and nature sectors. Projects were undertaken within these sector areas and are listed in the following Table.
