Résumé : It was the first mission of Cirad in Uzbekistan as part of the project “Mapping natural resources along the Amu Darya's banks in Uzbekistan and Turkmenistan” on behalf of GIZ (Deutsche Gesellschaft für Internationale Zusammenarbeit, GmbH). The aim was to get in touch with the local partners of the GIZ and the NGO KRASS (Khozerm Rural Advisory Service Support) by representing our colleagues CIRAD, UMR-Selmet and in particular Jean-Daniel Cesaro, project manager . The second objective was to take field measurements in the two zones of the LABR (Lower Amudarya Biosphere Reserve), located on the banks of the Amu-Darya River, in order to establish a database that can be used to carry out the classifications of images acquired recently by GeoSud-Theïa, via Audrey Jolivot (CIRAD-UMR-Tetis). We teamed up with Natalya Marmazinskaya (Zoologist) and Nimat Khudiyarov (Forest Service Representative). Oybek Matkarimou, director of LABR (Lower Amudarya Biosphere Reserve) received us and put at our disposal inspectors-rangers for each field day following our movements in the sectors concerned. We had free choice of our movements and our investigations We were able to collect 272 measuring points and walk 88km in autumn conditions (morning temperatures ranging from -5 to 2 ° C). Each measurement point contains 4 photos (oriented North, East, South and West), a quantitative description of the habitat (canopy height, average diameter of trees, crown area, height and density of understory vegetation, soil quality, list of species on an area of 20m in diameter) and geographical coordinates obtained by GPS. The forest is characterized by a Euphrates poplar forest structure whose density decreases as it moves away from the river to a pseudo-steppe at the edge of the valley. In addition, some forest areas have been converted into coppice due to accidental fires or logging. The complication of the mapping will lie in the distinction of the structure and the density of trees and understory that constitutes the food of deer. These two factors seem to us to be decisive for obtaining a map of the habitats of the LABR. The cartographic knowledge of these two habitats is essential to feed the file that GIZ wishes to present to UNESCO in order to obtain the Biosphere Reserve label. The LABR is home to one of the last populations of Bukhara Deer (Cervus elaphus Bactrianus), which is on the IUCN Red List. However during our field investigations, we were given the regular opportunity to observe these animals as well as the damage they cause to vegetation, especially to forest regeneration, in the southeastern zone of the LABR. On the occasion of this first mission, we were able to make the following recommendations: -To limit the overgrazing of the Southeast area of the LABR by deer that threatens the sustainability of the ecosystem, study in short terms the possibility of transferring part of the deer population in the North-West area. In the medium term, the extension of the LABR to ensure continuity between the two zones can be studied; -Partition of the LABR Core-Zones by strips of 100m wide (50m on either side of a track), classified as Buffer-Zone, so as to let visitors on these tracks and create firebreaks on which the undergrowth would be cleaned; -Maintain and enhance these firebreaks by allowing domestic livestock to graze and harvesting firewood (undergrowth and dead trees), under contract with the neighboring population; - Study the possibility of installing a metal or electrified fence on the boundary between the Transition Zone and the Core / Buffer Zone, west of the village of Tallyq, to limit deer intrusions and conflicts with local populations; -Study the possibility of including part of the Karatau ills and the riparian zone located at its feet, in the Core Zone or in the Buffer Zone of the LABR; -Initiate negotiations to extend the LABR on the south shore of Amu Darya, in Turkmenistan; on this occasion, see the need and the possibility of reintroducing deer; -Include the area of the citadels Jampik Kala and Kyzyl Kala, in the buffer Zone of the LABR; -Establish collaboration agreement between LABR and research organizations (national or foreign) in terms of dynamics and restoration of vegetation and wildlife, as well as in the field of soil salinization, history, relations with local populations, economic impact of the LABR, etc. If the project deems it useful, an expert from CIRAD (D. Cornelis) will be able to count the deer, by doing an overflight, for example in a small plane of 4 places. He could also train local partners. -Check the limits of the LABR by a GPS survey campaign with the rangers. This work could be an opportunity to review the boundaries between areas (Core, Buffer and Transition) and to include certain areas, to ensure better ecological continuity between the two major parts of the LABR. It now remains to draw up a cartographic model with the help of our Cirad colleagues. Another mission is scheduled for
