Abstract
The investigations were carried out in 2002-2006 in two municipalities of Konopnica and Jastków close to the western part of Lublin, Poland. The aim of the study was to identify the condition of bee flora and determine the floristic richness depending on the biotops in agricultural landscape. Flora of the anthropogenic refuge areas consists of 214 species, among them 80% were flow taxons. Apophytes (162 species - 78%) predominated on all types of biotops under consideration. Perennials predominated in flora of boundary strips and bush communities. Mainly annual (40%) and biennial (15%) species comprise the flora of fallows. A great number of bee taxons represent meadow, segetal or ruderal communities. Most of flow plants compose loose patches, but their successive blooming ensures a source of food for <i>Apoidea</i> from early spring till the end of summer. The flora of boundary strips, bush communities and fallows significantly increases the biodiversity in agricultural landscape. The treatments including sowing, mainly on fallows with nectariferous and polleniferous species, would enrich generally weak flows in highly agricultural landscape.
Highlights
The opinion about pollution of agricultural landscape is generally accepted
A great number of weeds are known as bee plants and can be important from two main points of view, as honey raw material and the development of wild bees colonies (Parish and Bazzaz, 1979; Jabłoński and Kołtowski, 1995; Wa rakomska, 1997; Wr óblewska, 2002)

Summary
The opinion about pollution of agricultural landscape is generally accepted (van Opstal , 2000). Rapid changes of agricultural technologies encouraged farmers to abandon traditional husbandry methods and mixed farming systems in favour of intensive enterprises with pesticides, herbicides, fungicides and other chemicals. New technologies influenced both segetal and ruderal flora. A great number of weeds are known as bee plants and can be important from two main points of view, as honey raw material and the development of wild bees colonies (Parish and Bazzaz , 1979; Jabłoński and Kołtowski , 1995; Wa rakomska , 1997; Wr óblewska , 2002). The expansion of specialisation and intensification caused unprecedented changes of forage base (Corbet et al 1991; Jabłoński , 2000)
