Swedish nature
Swedish nature
•We need better data on biodiversity in general and on the contribution of designated areas to species protection in particular
•Reporting regulations of the habitat directive
Natura 2000 in Sweden
• Initial confusion • Unsystematic data collection• (Very) preliminary assessments reported• Baseline survey to start next year
Baseline assessment
National project 2002-2003
•Focus on strategy and methods for monitoring of Natura 2000 network
•Should enable by January 2004 to start fullscale monitoring of swedish part of Natura 2000

Guiding principles
Conservation objective

Monitoring
Analysis, reporting
FCS
Objectives to drive the system
Guiding principles
Minimum intervention management >>
•Low frequency monitoring•Early warning systems
Guiding principles
Regular management or restoration management >>
•High frequency monitoring integrated in management system
Guiding principles
Spatial scale for assessment?
Natura report on the status of total national (and biogeographic) populations
Guiding principles
National and biogeographical assessment of FCS
National landscape surveillance
Other sources
Site-based monitoring
Guiding principles
Typical species (indicator value X abundans)
<Redlisted/Annex II species
<”Typical” (quality indicator species)
<Characteristic/ defining sp
Guiding principles
Late news - typical species to deliver!
Field tests 2003 affirmed use of typical species as indicator for habitat quality
Remote sensing:•Satellite data (monitoring)•Infra-red airborne (base-line survey)
Preferred techniques
Satellite data for mapping and monitoring of habitats with high
nature conservation values

New road
Sphagnum-dominated mire
Increased field layer (Carex, etc)
9010 Western taiga9110 Luzula-Phagetum beech forests7240 Alpine pioneer formations of the Caricion bicoloris-atrofuscae
Habitat examples
9010 Western Taiga
Subtypes:•Oldgrowth types by tree species
•Recently burnt stands
•Young post-fire successions
9010 Western Taiga
National objectives for network sites:
•No loss of habitat area
•No loss of pine dominated stands
•Not FCS area < 20% in next 30 years
National objective at landscape level:
•Stands of ”key habitat” quality be kept at same areal
9010 Western Taiga
Base-line survey should:
•Map distribution of habitat and subtypes
•Assess quality criteria (some subtypes)
Base-line survey techniques:
•Airborne IR photo
•Commercial land assessments, inventories
9010 Western Taiga
Monitoring should:
•Detect unwanted impact on network sites
•Detect changes in habitat quality
•Detect biodiversity losses
9010 Western Taiga
Monitoring techniques:
•Satellite data
•Landscape surveillance programmes
•Surveillance of nesting birds
9010 Western Taiga
Site-based monitoring of managed and restoration sites:
•Forest stand structure
•Tree species composition, regrowth
9110 Beech forest
National objectives for network sites:
•No loss of habitat area
•Extension of too small sites to include adjacent young stands
National objective at landscape level:
•Stands of ”key habitat” quality be kept at same areal
9110 Beech forest
Base-line survey should:
•Map distribution of habitat
•Quantify quality criteria (dead wood etc)
Base-line survey techniques:
•Airborne IR photo
•Field based survey
9110 Beech forest
Monitoring should:
•Detect unwanted impact on network sites
•Detect changes in habitat area / quality
•Detect decrease in dead wood
•Verify no (or few) spruce saplings present
•Verify regeneration of beech present
9110 Beech forest
Monitoring techniques:
•Airborne IR photo
•Field-based standard methods for forestry assession
•Specific field-based methods
7240 Alpine pioneer formations
National objectives for network sites:
•No loss of habitat area
•Control of bush or tree encroachment
•Control of erosion by vehicles/ paths
•No loss of (number of) typical species
7240 Alpine pioneer formations
Base-line survey should:
•Map distribution of habitat
•Assess quality criteria
Base-line survey techniques:
•Field based (on reported sites for habitat defining Carex species)
•Deliniation of habitat on ortogonal airborne photo
7240 Alpine pioneer formations
Monitoring should:
•Detect changes in habitat extent
•Detect changes in habitat quality
Monitoring techniques:
•Field based, semipermanent transect and plot sampling.
•Methods as already tested for seminatural grasslands.
