Abstract
<p>The present study was undertaken to evaluate the biodiversity of lichen species in Nowosady village and surrounding areas. This work was conducted in 2014 (in August) and biodiversity of lichen species growing on tree bark and bushes, on dead wood (anthropogenic origin), glacial erratics, concrete, mortared walls and other specific substrates like eternit roof slates has been assessed. The lichen species represented morphologically diverse forms: crustose (38%), foliose (38%), fruticose (13%), dimorphous (5%), placodial (3%) and squamulose (3%). They belonged to different ecological types including epiphytes (27 species), epixyles (18) and epilithes (12). Out of 39 species identified in Nowosady village, five are included in the Polish red list of lichens: <em>Bryoria fuscescens</em>, <em>Evernia prunastri</em>, <em>Hypogymnia tubulosa</em>, <em>Ramalina farinacea</em> and <em>Ramalina fraxinea</em>. Four taxons from the study area are under statutory protection of species. One species, <em>Ramalina fraxinea</em> is under full protection and 3 species (<em>Bryoria fuscescens</em>, <em>Evernia prunastri</em> and <em>Hypogymnia tubulosa</em>) are under partial protection.</p>
Highlights
Nowosady is a small village located at the border between two mesoregions: Białostocka Upland and Narew River Upper Valley
The diversity of lichen biota of orchards in different towns has been studied in Slovakia, Italy and Poland [8], and in several Polish villages or rural areas, including Warmia Plain [9], Klewinowo [10] and Hermanówka [11]
The lichen biota was analyzed using methods that are generally accepted in lichenology
Summary
Nowosady is a small village located at the border between two mesoregions: Białostocka Upland and Narew River Upper Valley. The diversity of lichen biota of several Polish cities has been investigated, including Gdańsk, Sopot, Gdynia [1], Olsztyn [2] and Świdnik [3]. The lichen species inhabiting smaller towns on Podlasie, like Drohiczyn [4], Mielnik [5], Boćki [6] and Białowieża [7] have been described. The diversity of lichen biota of orchards in different towns has been studied in Slovakia, Italy and Poland [8], and in several Polish villages or rural areas, including Warmia Plain [9], Klewinowo [10] and Hermanówka [11]. The main goal of the present study was to evaluate the biodiversity of species in the Nowosady village and its surrounding areas, taking into account their natural environmental conditions
