Pollen analysis of a 270 cm deep guano deposit from Măgurici Cave (NW Romania) was performed to understand the vegetation dynamics and the influence of deforestation and farming activities that unfolded in the Transyl- vania area over the past 800 years. The study discusses the value of cave guano as a source of palaeoclimate data and tests if guano sequences record the same signals as other proxies (tree rings, speleothems, lakes or peat). The

Pollen analysis of a 300 cm deep guano deposit from Magurici Cave, N.W. Romania was performed in order to highlight the vegetation dynamics and the influence of deforestation and agricultural activities that unfolded in the area over the last 800 years. The obtained data is consistent with the known vegetation history over the late Subatlantic period, with well known climatic events recorded, such as MCA (Medieval Climate Anomaly) and LIA (Little
