The article aims to assess the survival rate of saxaul plantations on the dry seabed of the Aral Sea (DSAS) and these close to the villages along the original seacoast. Protective black saxaul (Haloxylon ammodendron) plantations on the DSAS were established in the course of 2009-2019 with the grant support of the International Fund for Saving the Aral Sea (IFAS), Japan’s environmental funds, UNDP Kazakhstan, as well as under the Grass-Roots Program of the Embassy of Japan in Kazakhstan. During September 1-14, 2020, the target plantation plots at 24 sites adjacent to the villages of Aralkum and Karateren underwent examination, including forest surveying, projected species cover determination, as well as seed regeneration and survival rate assessment. The findings of 2020 revealed the varying condition of target saxaul plantations. Thus, the survival rate of saxaul inside forest plantations ranged between 0.12 and 78.0%. The actual number of saxaul trees varied from 1 (one) to 1,000 per ha on the DSAS and from 888 to 2,633 per ha in Aralkum village. The novelty of the obtained results is due to the fact that they clearly demonstrate that the survival rate and development of forest plantations, as well as saxaul seed self-renewal, above all, depend on the overall ecological conditions at specific sites. Saxaul demonstrated the best survival rate and growth at the sites with sandy loam and saline light loamy soils with sandy cover, and the worst – at the sites with crusty and takyr (dry-type playa) saline soils.

This article presents a new method of laboratory density determination and construction equations of state for marine waters with various ionic compositions and salinities was developed. The validation of the method was performed using the Ocean Standard Seawater and the UNESCO thermodynamic equation of state (EOS-80). Density measurements of water samples from the Aral Sea, the Black Sea and the Issyk-Kul Lake were performed using a high-precision laboratory density meter. The obtained results were compared with the density values calculated for the considered water samples by the EOS-80 equation. It was shown that difference in ionic composition between Standard Seawater and the considered water bodies results in significant inaccuracies in determination of water density using the EOS-80 equation. Basing on the laboratory measurements of density under various salinity and temperature values we constructed a new equation of state for the Aral Sea and the Black Sea water samples and estimated errors for their coefficients.
