Paleo-archives may be used to understand past ecologies. This requires quantification of the storage, or rather preservation, potentials of extant biology. An important effort in this quantification for past ecological purposes is the Land Use Land Cover (LULC) models. These models relate proportions of taxa in terms of pollen, phytoliths, etc., in surface soil to those of species in a landscape and environment. LULC models have vastly different applications, ranging from simple assessments like forested and non-forested fractions to quantifying anthropogenic influence and different forest types. These models, however, lack data and information on applicability in the tropical and subtropical regions of the global south. This session brings together scholars using various methods for calculating pollen productivity estimates (PPEs) or pollen fall / depositional rates (PFRs) that can be adapted to the Global South.
