Biodiversity Trust has
19 groups and agencies
as founding members.
The condition of remaining wetlands is
improving under the Council's programmes.
72% of wetlands covered by Council-developed
biodiversity plans showed improvement
in overall condition between 2010 and
2015, compared with 31%
of wetlands without a plan.
There has been a
small (1.3%) loss of

Land management issues that are tackled in a comprehensive
farm plan include :
Hillslope stabilisation
Gully erosion control
Farm woodlots
Farm shelter
Scrub and bush retirement
Pasture improvement
Fencing subdivision
Track layout
Drainage
Wetland conservation
Impact on stock numbers and farm income
The plan is supplied on a no-cost, no-obligation basis,
