Vascular Plants Distribution as a Tool for Adaptive Forest Management of Floodplain Forests in the Dyje River Basin

The study is based on a full floristic inventory of floodplain forests in South Moravia along the upper part of the Dyje River (Forest district Valtice). The study area is located in the Dolní Morava Biosphere Reserve and includes several Sites of Community Importance within Natura 2000. The aim of the inventory was to analyze diversity of herb and woody species occuring in the study area, including both native protected and threatened species, and invasive species. The study area was divided into segments. A segment represented the smallest unit of spatial forest division - "forest stand part". The species were recorded into a special scratch-list. Altogether, 656 plant species were found. The floristic database has been integrated with GIS. Maps of distribution of selected plant species or groups of plants were produced. On the basis of geographical visualization of the above mentioned results we identified areas with a high diversity of all species and endangered species. The results may be used as a base for adaptive forest and environmental management.

ABSTRACT

This paper presents an evaluation of full-area floristic mapping of floodplain forest in Tvrdonice forest district (Židlochovice Forest Enterprise) based on a single forest stand inventory. The study area encompasses 2,200 ha of forests, where 769 segments were inventoried, and 46,886 single records about presence of vascular plant species were catalogued. We found 612 species (incl. subspecies and hybrids), out of which 514 were herbs, 98 were woody plants, 113 were endangered species and 170 were adventive species. The average area of a segment is 2.86 ha. The mean number of species per segment is 60.97 in a range of 4-151.

Abstract

This paper presents an evaluation of full-area floristic investigation of floodplain forests in Soutok forest district (Židlochovice Forest State Enterprise) based on an individual forest stand inventory. The study area encompasses 5103 ha of forests, where 1186 segments were inventoried, and 71 223 single records about presence of vascular plant species were done. We found 761 taxa (species, subspecies and hybrids), out of which 655 were herbs, 106 woody plants, 156 were endangered species and 177 adventive species. The average area of a segment was 4.3 ha. The mean number of species per segment was 64.42 in a range of 4–180.

Abstract

Ancient coppice woodlands are coppice-originated forest stands with a long-term continual development, and with the preserved typical natural and historic elements of old sprout forests. Prominent natural elements in the ancient coppice woodlands are namely old coppice stools. There is, in scientific literature, lack of information about features of ancient coppice stools. Therefore, our contribution aims to describe shape and form of ancient coppice stools, including the most important microhabitat of coppice woodlands – dendrothelms. Based on field survey of 20 localities of important coppice woodlands we recorded 135 ancient coppice stools of 13 tree species and a total of 80 dendrothelms in 9 tree species. Basic features of ancient coppice stools and dendrothlems were measured and evaluated.
