We'll take green-down measurements at the same tree [Autumn '20/Spring '21/Autumn '21/Spring '22], an old Pedunculate oak [Quercus robur] at least 200 years old. The branch we've been observing from '20 has dried so we have selected another southeastern branch at 340cm high [the lowest of this tree]. We are using a kind of aluminum ladder to take observations and we know some safety tips for working at heights ;)
You can check this link for past year's green-down measurements.
The site is located on the eastern slopes of mt.Olympus, in the heart of broad-leaved evergreens [Quercetalia ilicis] at an altitude of 580m. The area is dominated by shrubs and low-rising trees such as the holm oak [Quercus ilex], Greek strawberry tree [Arbutus adrachnae], kermes oak [Quercus coccifera], strawberry tree [Arbutus unedo], prickly Juniper [Juniperus oxycedrus], etc. Characteristic deciduous species at this altitude include manna ash [Fraxinus ornus], Montpellier maple [Acer monspessulanum], Judas-tree [Cercis siliquastrum], European smoke tree [Cotinus coggygria] and others.
The MUC field code is 0192 and described as closed forest, mainly evergreen, temperate and subpolar needle-leaved, irregularly rounded crowns.
Climate can be described as one of Mediterranean type with continental influence, hot and dry in the summer, while humid and cold in the winter. Its local variations are the result of the impact of the sea and the rugged relief of the region.
