2. an example of a HELP catchment a real catchment (2000+km2) - not an experimental catchment real issues: - land-use effects on water yield - conflict over surface and ground water use - low flow and sediment impacts on trout fishery - land-use effects on water quality (nutrients, bacteria) how can research help to manage the effects of all uses, and to resolve or manage conflicts over resources

5. Simplified geology and rainfall distribution in the Motueka catchment.

6. Primary forest in high-rainfall upper catchment. Used for biodiversity conservation, tourism, recreation.

7. Natural and plantation forests on gravel hill country, mid-upper catchment

8. Recently harvested plantations on gravel hill country. Little erosion or sediment impacts in contrast to the harsh visual impact.

9. Roads and recent harvesting in plantations on granite hill country. Large amounts of fine sediment produced from roads and harvested areas is transported into streams.

10. Mixed land uses in mid-catchment, gravel hill country near Tapawera. Irrigated horticulture on terraces near stream. Typical main-stem stream channel.

11. Intensive horticulture on valley flats. Sheep/cattle grazing and plantations on gravel hill country.

12. Gravel hill country inferred to be recharge zone for aquifers. Plantations restricted to 25% of total area here.

13. “Lifestyle” small farms on gravel hill country near the coast.

14. Lower reaches of Motueka River and small flood plain surrounding outlet to Tasman Bay.

15. Intensive horticulture on Motueka River flood plan and terraces close to outlet to Tasman Bay.
