Core Viewpoint - The appearance of yellow foam on the surface of Sayram Lake is due to seasonal pollen accumulation, not pollution, and this phenomenon is a natural occurrence that lasts for a limited time each year [1][3][5]. Group 1: Pollen Phenomenon - The yellow foam observed on Sayram Lake is primarily found in areas with abundant grassland around the lake [5]. - Laboratory tests revealed that the yellow foam contains dozens of types of pollen, which is produced during the flowering season from mid-May to mid-June [5][7]. - The unique climatic conditions of Sayram Lake allow pollen to rise into the air and then fall into the lake, creating the visual effect of "yellow foam" [7]. Group 2: Ecological Impact - The "pollen sea" phenomenon lasts only 15 to 20 days, with peak concentration occurring between June 10 and June 15, coinciding with the flowering period of surrounding wildflowers [9]. - Pollen contributes to the food chain, as microorganisms consume it, which in turn supports the growth of fish like the high white salmon [9]. - The management committee of Sayram Lake plans to monitor flowering periods and predict the formation of the "pollen sea" to enhance visitor experience and education [9].
