Survey and assessment of vegetation in the CONECOFOR permanent plots

Phytosociological knowledge of plant communities and their synecological allocation are the reference basis of the CONECOFOR Programme. Vegetation surveys are performed in all the CONECOFOR plots (28), and have been performed in most of them for 6-7 years, following two fundamental approaches: (1) phytosociological (plant community level) and (2) dynamical (population level). According to a syn...

Crown condition assessment at the CONECOFOR Permanent Monitoring Plots

A detailed crown condition assessment is currently being carried out at the CONECOFOR (CONtrollo ECOsistemi FORestali, Control of Forest Ecosystems) plots. The assessment began in 1996, and during the first two years (1996 and 1997) an assessment form based on previous regional experience was used; in 1998 the new official EU form was adopted. The resulting loss of comparability means that only...

How reliable is the monitoring of permanent vegetation plots? A test with multiple observers

Questions: A multiple plots design was developed for permanent vegetation plots. How reliable are the different methods used in this design and which changes can we measure ? Location: Alpine meadows (2430 m) in the Swiss Alps. Methods: Four inventories were obtained from 40m-plots: four subplots (0.4 m) with a list of species, two 10m-transects with the point method (50 points on each), one su...
