These were junk tags automatically generated by my GIS. Now I have removed them. Thanks!

Hi,
thanks for comment.
These landcover tags are still "raw", not final.
In the Russian-speaking OSM-community there is a discussion on the scheme for tagging landscapes (woodlands, shrubs, etc.). Much can change. Writing proposal still premature.

1. Трасса не имеет формальных признаков для присвоения ей тега highway=unclassified:
2. Раз "лыжероллерная трасса" со строчной буквой, значит это не название.
