Betula nana, Betula nana-type or they are included into a general category of Betula pollen.
Some of the most interesting macrofossils found in the sediments of this area are the remains of cold-tolerant Betula nana L.
Jundzill indicated: "We found very rare species and species which have never been found before, such as Callitriche intermedia, Circaea alpina, Circaea intermedia, Calamagrostis schleicheri, Koeleria cristata, Sesleria caerulea, Scirpus caricinus, Primula farinosa, Salsola kali, Chenopodium villosum, Ribes alpinum, Swertia perennis, Lunaria rediviva, Alyssum montanum, Cakile maritima, Dentaria bulbifera, Taxus baccata, Betula nana
, Myrica and many other cryptogams".
Evidently, the planet is some size and despite the acreage of small leaved Betula nana
consumed by reindeer, the fellow in the pillar box red tunic wouldn't finish his shift were it not for those generous helpers that parents, aunts and uncles, brothers and sisters, so visibly are.

The pollen production of local taxa is very low, among which Betula nana
, Salix, Selaginella selaginoides, Dryas octopetala and steppe xerophytes Eurotia ceratoides, Ephedra and halophilous taxa Kochia prostrata, Salsola kali and Salicornia herbaceae have been identified (Pirrus 1971).
Unfortunately, in our diagram, the pollen of Betula nana
and the other Betula species have not been calculated separately.
makes up 8% and Alnaster 2% in layer VIII.
but in addition, the remains of Betula nana
, Juncus and Potamogeton filiformis are noted.
The LPAZ is characterized by abundance of Betula nana
and herb pollen that reach 18% of the total sum (Fig.
At the Pinus peak around 430 cm Betula nana
pollen disappeared and Betula, Juniperus, Artemisia, and Cyperaceae pollen decreased.
Pollen assemblages recovered from periglacial middle Jarva layers of the Toravere, Valguta, Savala, and other sections were interpreted by Liivrand (1991, 1999) as evidence of cold environments with wide-spread tundra and xerophytic communities dominated by Betula nana
, Artemisia, Chenopodiaceae, Poaceae (Gramineae), and Cyperaceae.
