Landscape-level Reserves
- Rational designProject DS 04(b)
• Objectives:
• to explore different approaches to reserve design
– SSS vs. TEM
– Utility of Marxan inputs
• to recommend an effective, efficient approach

Design vs. Planning
• Design – technical procedure; data-
centered
• Planning – an inclusive process
involving First Nations, operational
forestry personnel, focal species
experts and other stakeholders

Stafford LU Design TL5
- low risk for focal species - representation based on TEM

Stafford LU Design LK
- low risk for focal species - representation based on SSS

Stafford LU - Design TL5 cf. LK
- representation by TEM cf. representation by SSS
• Pink is
common to
both – 60%
• Green is LK
only
• Orange is
TL5 only
• Use TEM
where
available

Stafford LU – Best30Mx cf. Marxan step3
- same goals - rational design using Marxan vs. Marxan alone
• Pink is common to both
• Green is Best 30 w Marxan (130)
• Purple is Marxan step 3 (2260)
• Use Marxan to explore target options

w Marxan (130)
• Purple is Marxan
step 3 (2260)
• Fragmentation,
edge/interior,
integrity
• Focus on value,
not necessarily old
seral
• Designs not plans
- concern
