What is systematic conservation planning?
Conservation planning: guides decisions about the location, configuration and management of conservation areas
Conservation areas: areas managed for the persistence of biodiversity and other natural values (is NOT just about reserves)
Efficient, repeatable, transparent and equitable process for making conservation decisions
-
What determines conservation priority?
Suitability for other uses, scenic beauty, recreational value Charismatic animals

Selecting conservation areas
To solve efficiently we first need to establish th is question as a formal problem
Two typical conservation area selection problems:problems:
The minimum set problem; capture a set amount of biodiversity for the least cost
The maximum coverage problem; capture as much biodiversity as possible beneath a fixed budget

Some misconceptions
Prescriptive black box
Only suitable for data-rich regions
Only applicable to strict reserves
Technically demanding
Precludes experts
Does considering cost prevents me from
getting a biologically pure answer?
-
Keep in mind
Computational capacity or algorithms rarely limit conservation planning lack of clear objectives do
Most issues arise because of communication challengeschallenges
Many complexities can be added More complex spatial rules Zoning Risk Dynamics
