The GLORIA Multi-Summit Approach

At the GLORIA Conference 2010 Sept. 23-26, Perth, Scotland, around 100 members of GLORIA agreed on a refined and streamlined catalogue of methods resulting from the field experience of the first decade of GLORIA.

For a detailed description of the GLORIA Multi-summit approach download the Field Manual v5
(English version, Versión española, Chinese version, Russian version) !

In summary, the components of GLORIA's Multi-Summit approach were divided into the two groups 'obligatory' and 'optional'.

Obligatory activities

  • Species (vascular plants) recording in 16 1m x 1m quadrats:
    • visual cover estimation
    • point framing (100 points per quadrat as a new application)
  • Species recording in 8 Summit-Area-Sections + abundance estimation defined on an ordinal scale (r!, very rare; r, rare; s, scattered; c, common; d, dominant)
  • A careful photo documentation of plots and summit set-up
  • Continuous soil temperature measurements (4 points per summit site)

Optional activities (in addition to the obligatory activities)

  • Bryophytes and lichens recording
  • Subplot-frequency of species in 1m x 1m quadrats (previously this was a standard method)
  • Increase of 1m x 1m quadrats up to 32 per summit site
  • Estimation of species cover in Summit-Area-Sections
  • Line-pointing in 10-m squares (4 per summit)

The new Field Manual v5 also lists a variety of additional activities (Invertebrates monitoring, plant functional types, transects, traditional knowledge, socio-economic aspects) as defined at the conference in workgroups or already applied at some sites.

The target region

This is GLORIA's basic approach. The main considerations in designing this approach were comparability, simplicity and economy for a effective network with a large number of sites. Four summit sites arranged along the elevation gradient are the minimum requirements for a GLORIA target region.

Summit area sections

Summit divided into 8 sections: samples of the summit flora to detect species migration

Quadrat cluster (3m×3m)

with 4 permanent 1 m2 plots. 4 clusters per summit (one in each main compass direction)

1 m2 quadrats: visual cover estimation of all species and pointing with a grid frame

detailed species cover sampling to detect changes in the species composition

Temperature measurements

in each 3m x 3m quadrat cluster in one-hour intervalls to compare changes of the temperature

Supplementary recording: Frequency counts

in the 1 m2 quadrats to detect changes of vegetation patterns

Supplementary recording: line-pointing and species recording in 10m×10m squares
