On the territory of Bulgaria the species fulfills the IUCN criteria for critically endangered [CR C2a（i）; D] and is included also in the Red Data Book of Republic Bulgaria and Biodiversity Act. The present study aimed to explore and evaluate the status of its populations and their threats. Materials and methods： Exploration mad monitoring of the populations of the critically endangered orchid O. insectifera in Bulgaria was done from 2012 till 2017. The shoot count and some morphometxic parameters were recorded for evaluation of their distribution and population dynamics. Results and discussion： At one location Ophrys insectifera can be considered extinct. However two new locations were found so the total number of known locations is increased. Approximately over 50% of the occupied territories fall outside protected sites and many of the habitats axe endangered by anthropogenic or other factors. At all of the known locations there are less than 50 shoots per place. These facts put a high stress on the perspectives of their populations＇ survival in Bulgaria.展开更多

This note on the orchids will enrich the already existing data on the area of Tlemcen. Currently, the coexistence of orchids and species （such as Quercus faginea subsp. tlemcenensis （DC.） M., Lonicera implexa L. and Ruscus aculeatus L.） indicates an ecological environment of dominant forest. Nevertheless, the significant frequency of fires and human pressure is leading to erosion of this area orchids richness. This work enabled us to establish a complete inventory of the orchids species that exist, with an estimate of the populations and a taxon illustration for each of them. Fourteen species （14） were indexed, during the period of spring 2011 only, in this reserve and the scoured areas which do not exceed 2000 ha, representing 29% of the total Algerian orchids species. Among the rare taxa signed ourselves： Ophrys subfusca subsp. battandieri （Rchb.） Batt. and Dactylorhiza durandii （Boiss. and Reuter） M. Lainz in Oranie （O）＊展开更多
