systematic approaches to conservation planning in freshwater systems
matt wattsjosie carwardinejon nevillcarissa kleinleon metzelingand many others
the aim of conservation planning
across a landscape, given limited budget: where to allocate conservation and restoration effort?
maximum efficiency -> healthy environment and minimum impact on stakeholders
completeness, adecuacy , representativeness, efficiency: the CARE principles
traditional methods: naturalness
naturalness based methods introduce spatial bias and will not deliver complete coverage of biodiversity
‘advanced’ traditional methods: scoring

why not use richness/scoring systems?

aim: protect all native fish taxa using least effort
why not use richness/scoring systems?

complementarity
aim: protect all native fish taxa using least effort
why don’t metrics work?
the cricket team analogy: what happens when we use the highest ranked players?
team a: 11 batsmen (scores many runs)
team b: 11 bowlers (prevents opposition from scoring)
both teams will lose
lessons from cricket
the whole is larger than the sum of its parts
whatever you do, always state a purpose (set targets) need a team that can
score high, while minimising the opposition score
set conservation targets (species, habitats, ecoregions)
optimisation algorithm (complementarity-based)
sitessites
featurescost
minimum set (the best plan fulfilling all targets)
irreplaceability map (how important is the unit for alternative plans)
systematic conservation planning
see Margules & Pressey, Nature, 2000
why is it systematic conservation planning still not frequently used in aquatic systems?
we need too much data
spatial configuration is it going really to protect
stuff (adequacy)?
we can’t lock everything up
a) we need too much data
systematic approaches need exactly as much data as richness/scoring approaches
possible surrogates: surrogates based on biological survey data biologically informed physical surrogates ‘tempered’ physical surrogates physical surrogates

other approaches (turak, in press, esselman, in press)
risk surfaces avoid subcatchments with
a high risk/disturbance
c) adequacy
no ideal solution in any realm (but a lot of work in progress)
target setting and connectivity
mixed landuse/protection schemes
d) we can’t lock everything up
mixed zones (abell 2007) flexible catchment rules (hermoso et al., in
press) cost surfaces
