Wild tulips are the most impressive of all diversity of flora of Uzbekistan. In the last 
decades, as a result of intensive anthropogenic impact, the range and population 
numbers of many tulip species have considerably declined. The current Red Data 
Book of Uzbekistan [Red Book, 134-154]. includes 19 species of 
Tulipa
, 20 species 
are protected in national parks and nature reserves. But none of the Central Asian 
tulips have been included in the IUCN Red List of Threatened Species (2011) [8, 
www.iucnredlist.org
]. 
The problem of the protection of the environment and flora is of great and vital 
importance for the whole humanity. Using natural resources, people negatively 
influence on the natural age-old landscapes. Development of industry and agriculture, 
extensive reclamation of natural territories lead to the breach of eco- logical balance. 
As a result of this, the danger of impoverishment of species composition of flora and 
loss of plants' gene fund increases. Disappearance of any species causes irreversible 
consequences, as wild plants make the feedstock for the creation of valuable varieties 
of many cultures. 
The species is able to successfully maintain its abundance in the prevailing 
environmental conditions under certain types of permanent effects on their habitat. 
Population size in the study area is sharply decreasing everywhere. These species are 
unstable when grazing, recreational load, mowing, gathering on bouquets. They can 
be preserved in natural places of growth in specially protected natural areas (reserves, 
botanical reserves and natural monuments). For each specific population of plants
specific measures should be developed considering their ecological and biological 
features. 
 
All the species studied are included in the Red Book of the Republic of 
Uzbekistan (except, 
Tulipa borszczowii
). However just registering species on the 
page of the Red Book is not yet a guarantee of preserving its genetic fund in full. 
Special legislative acts and effective control of their execution are necessary. Only 
the involvement of all citizens of the Republic in the cause of protection of nature and
