Low-Input Agriculture as a Chance to Preserve Endangered Species of Segetal Flora

As a result of human activity, the rate extinction species is now 100 to 1000 times faster than under natural conditions [1]. According FAO, 75% genetic diversity agricultural crops worldwide has been lost since 1990. In Poland, about field weeds are in danger extinction. Archaeophytes growing on heavy calcareous soils, which characteristic Lathyro-Melandrietum noctiflori, Caucalido-Scandicetum, Kicxietum spuriae communities, and associated with cultivation flax, particularly endangered. Halting loss rural biodiversity priority for EU’s environmental protection strategy. Research aimed at assessing infestation status weed agrophytocoenoses, located rendzinas Lublin Province (Poland), conducted 1997. The research was carried out using Braun-Blanquet phytosociological method. south-eastern part Poland. Here, there good production. Agricultural land covers 57.9% total area voivodeship, 99.3% suitable standard farming. such favorable conditions, agriculture characterized by an unfavorable structure farms: 55.6% more 180,000 farms those 5 ha. Such large fragmentation results low profitability sector, from extensive shown that low-input conducive preservation rare endangered segetal flora [2]. Muscari comosum—a critically (ER) strict protection—were found several sites study area. Several Caucalis platycarpos Galium tricornutum, also recognized as ER species, were rendzinas. Moreover, numerous Adonis aestivalis, Anthemis tinctoria, Thymelaea passerina, Lysimachia arvensis, Chaenorhinum minus Euphorbia exigua identified. state population key challenge scientists, because only knowledge this will provide basis future relevant actions maintaining restoring degraded ecosystems [The poster presentation].
