1 Programme of restitution Taxus baccata L. and Sorbus torminalis (L.) Crantz in Polish State Forests Michał Magnuszewski Directorate General of the State Polish Forests Conference EX situ conservation of plants – problems and solutions, Poznań, 9-13 September 2015, Poland The detailed achievements of programme are: Developement of production method of yew planting material by diferent technologies (seeds, the branch cuttings, the seedlings come from the nature reserves) Planting (ex situ) 400 thousands of pieces yews seedlings in forest culture, in the total area of 180 hectares in the State Polish Forests Established the seeding seed orchads and another reproductive objects Where was possible, care of yew (in situ) in nature reserve Popularization of knowledge about the active conservation (ex-situ) Realization of the ‘Programme of restitution Taxus baccata L. in the State Polish Forests started in „The program of yew protection and restitution in the State Polish Forests” was established on Regional Directorates of State Forests actively participates in the program where yew occurs the bigest area. Regional Directorates of State Forests in Gdansk, Katowice, Kraków, Krosno, Pila, Poznan, Szczecin, Szczecinek, Torun and Wroclaw participate the most intensively. Rules of yew ex-situ restitution : inventory of yew stands and recognizes the usefulness for restitution at first to restitution were typed 36 population in the natural forest regions (Fig. 1 ) after the genetic research (Fig. 3) and identification of genetic variation of yew population in Poland, 24 population were selected to the futher restitution in typed three forest regions (Fig. 2) Fig. 1. Natural forest regions with main yew population in Poland ( by Programme of restitution Taxus baccata L. in the Poland 2006) Fig. 2. Regions of restitutions (typed after the knowlege of yew genetic variability) I Region (Natural regions: Bałtycki, Mazursko -Podlaski, Wielkopolsko-Pomorski) II Region (Natural regions: Śląska, Sudedka) III Region (Natural regions: Małopolska, Karpacka) IV Natural regions forests ( Mazowiecko Podlaski) without populations of yew Yew in the nature reserve „Cisy Staropolskie im.

Michał Magnuszewski ) Yew and whitebeam (wild service tree) are species under conservation occurring in the Poland different regime of protection. Yew is covered by a partial conservation, whitebeam by strict conservation (with the guidance of the passive protection,…?) Regulation of the Minister of Environment dated 9 October 2014 (Dz.U ). Population of these trees were reduced because of unique quality wood used to many things. For example yews wood was used to military purposes (bows, crossbows), whitebeams wood for furnitures. The action of Polish Foresters resulted that yew population at present is no longer in danger. Yew from from regime of strict conservation, became the regime of partial conservation!!! Yew (in Regulation of the Minister of Environment dated 5 February 2012 (Dz.U ) – was under strict conservation, whereas in Regulation of the Minister of Environment dated 9 October 2014 (Dz.U ) regime was changed to partial conservation.) According to the knowledge of specialists yew is not an endangered species, but it should be taken into action of protection (in situ) in nature reserves, where slowly extinct. According of the example „Programme of protection and restitution of yew in SPF”, the action will be taken to create the „Program of protection and restitution of whitebeam (service wild tree)” in this year. In the area of State Polish Forest whitebeam occur in the 84 natural stands (in total there are 3500 trees) [Bednorz 2009] (Fig. 3.) In Poland whitebeam (service wild tree) is planting within the natural range (Fig. 3.) on regional scale. For example in the Regional Directorate of State Forest in Pila in years according to [Kmiecik and all. 2015] 20 Forest district planted (ex- situ) in total pieces seedlings. Fig 3.
