The landscape’s reservation area is 4499 ha according to the Law of State Protected Natural Areas. According to the forest management plan from 2011, the area of the landscape’s reservation in “Padurea Hâncesti” is 4573.1 ha. It is located in Mereşeni and Logăneşti forest district, the State Forest Enterprise Hânceşti. In 2015 (march-august), we studied the flora of downy oak forests from the reservation to emphasize the floristic composition and to elaborate measures to optimize the biodiversity conservation. The researches were done in the parcels with downy oaks (Quercus pubescens) using the itinerary method. The known species were registered in the journal, and the unknown species were collected in a herbarium according to A. Skvortov (1977). To determine the plants from the herbarium, we have also used the plant determination of T. Geideman (1986), V. Ciocarlan( 1988-1990), A. Negru (2007) and the works like: “ Flora R.P. României” (1952- 1976), Al. Beldie (1977- 1979),etc. The downy oak forests (Quercus robur) from the landscape reservation “Pădurea Hâncesti” extend on a 260.8 ha area. The biggest areas of downy oak stands are in the Mereseni forest district (224.3 ha). The general area of fundamental natural stands of downy oak (Quercus pubescens) is 258 ha. The general area of the partially derived downy oak stands (Quercus pubescens) from the reservation is 1.4 ha (Logăneşti forest district). There were planted downy oak stands (Quercus pubescens) in Mereşeni forest district on a 0.9 ha area, but in Logăneşti forest district – 0.5 ha. (parcel 47 W) There are present pure downy oak stands. There were distinguished some mixed stands of sessile oak (Quercua petraea), linden (Tilia tomentosa), ash (Fraxinus excelsior), cherry (Cerasus avium), maple (Acer platanoides), etc. In the shrubs’ layer, the cornelian cherry (Cornus mas), smoke tree (Cotinus coggygria) prevail more often. Less present but frequent there are the hawthorn (Crataegus monogyna), (Euonymus verrucosa), etc. The herbaceous coating is richer on meadows and it changes during the growing season.   In the result of the research on downy oak forests from the reservation, there were distinguished more than 90 species of vascular plants including 15 trees, 14 shrubs and more than 84 herbaceous plant species. In the greater majority of the studied stands there prevails the downy oak (Quercus pubescens). At the start of the stands prevails the smoke tree (Cotinus coggyygria) and in some cases the cornelian cherry (Cornus mas). Under the crowning of the stands the herbage percentage is 4-15 %. On glades, the herbage covering percentage is 90-100 %. There is not observed the domination of any plant species on the herbaceous coating on glades. More frequent on glades there are the herbaceous plant species like nodding sage (Salvia nutans), wild strawberries (Fragaria vesca), the british yellowhead  (Inula britannica), tall skullcap (Scutellaria altissima), lesser periwinkle (Vinca minor), wood avens (Geum urbanum), lesser meadow-rue (Thalictrum minus), etc. In the downy oak forest of the landscape reservation “Pădurea Hânceşti” there were distinguished 9 rare plant species: prunus tenella (Amygdalus nana), pheasant's eye (Adonis vernalis), Adonis volgensis, garden asparagus (Asparagus officinalis), Asparagus tenuifolius, Belevalia sarmatica, prairie crocus (Pulsatila montana), feather grass (Stipa lessingiana), tassel hyacinth (Leopoldia comosa).
