Many thanks Igor. As regards that unusual coloration, there's a lot of pollution sources at our town park; undisciplined (to say the least of it) pedestrians mark their ways generously scattering food wrappings and empty bottles; some drivers prefer to wash their cars themselves near the river, so the traces of oil products can be found almost everywhere...
