Sip-Sin 


sip-sinSip-Sin covers 7,000 ha of the reserve's territory. This area includes wavy, sandy steppe with scattered birch and aspen trees, seasonal salt and scattered small lakes. Some pine groves can be found in its central area. This area resembles the forest-steppe lands of western Siberia.

TersekTersek covers 6,700 ha of the zapovednik. The pines here grow as a long band, rather than in groups like Naurzum, and are surrounded by steppe.

Naurzum 


NaurzumNaurzum is the central section of the reserve, covering 71,600 ha. Pine forests, covering 160 sq. km, steppe and the lake systems, Aksuat and Sari-Moen, are found in this area. The pine trees grow on sandy hills with aspen and birch trees separated by steppe and sometimes saline lakes. When looking at this area from a distance, the small groups of trees and open prairie look similar to an African safari.

  • CIS: Commonwealth of Independent States; The Former Soviet Union.

  • Ecosystem: a group of different plants and animals that live together and are dependent on the area in which they live.
  • Land-locked: surrounded on all sides by land; no access to large bodies of water.
  • Saline: salty.
  • Steppe: prairie or grassland

  • Zapovednik(i): a Russian word for national nature reserve.

Where in the world is Kazakhstan (Ka-zakh-ston)? This may be a puzzling question to some. However, the following summary of Kazakhstan will help put the pieces together!

  • Biased: when someone presents only one viewpoint. Biased articles do not give all the facts and often mislead the reader.
  • Conclusion: what a person decides based on information they get through research including experiments.
  • Method: following a certain set of steps to make something, or find an answer to a question. Like baking a pie or fixing the tire on a bicycle.
  • Research: looking for answers to questions using tools like the scientific method.

Conclusions

Conclusions

So what can we conclude from this study so far?

One, that the wastewater chemistry is very different from that of natural waters, contain high concentrations of nutrients. Two, saltcedar dominates the riparian plant community in basal area and density for both the effluent and control sites. Three, the rate of growth in all three tree species increases when exposed to wastewater. And four, there appears to be more birds using the wastewater site than the natural site, with fish-eaters and blackbirds having the greatest impact.

Survey of Birds

Survey of Birds

Survey of Birds

A study was done on the birds that use these rivers. The birds were identified and counted once during the summer and once during the fall, both in the morning and in the evening. As can be seen by the figure, the number of different kinds of birds seen in each study area was nearly the same (11 species along the wastewater study area and 10.5 along the control), but the total number of birds present was greatly increased along the wastewater study area.

Tree growth rates

We wanted to see how nutrient-enriched wastewater might influence the rate of growth of the three dominant tree species. To determine this, we needed to measure how big around some trees were and then remove cores from them. Cores are pieces of wood that are removed from the tree (they look like a pencil) that let us see how much growth occurs each year.
