The Mappers Challenge got buried under a long list of newer diary entries, so as today is the 31st Jan I will post about my contribution here:
My land area is part of the Majos Valley, the flood plain of the biggest river in Karolia and two national parks: https://opengeofiction.net/#map=14/51.7633/111.7834
The peaceful landscape is largely grassland [landuse: check] and has only a few gentle hills which the river meanders around. On the higher ground the grasses become heathland [landuse: check]. The river has shifted course a lot in its history and many oxbow lakes and ponds exist [landuse: check], as well as extensive reed beds [check] and wet meadows [check]. Some of the watercourses are man-made, from attempts to farm aquatic produce and fish, as well as manage the drainage off the land.
'Limited infrastructure' means few roads. Instead the railway and long-distance cycle and footpaths are the access to this area. These run on boardwalks over the marshy ground, and also on a special bridge over the railway line. This wasn't strictly necessary as traffic is light enough for a level crossing, but it was built to allow a view and information displays about the grasslands towards Majoslinna, the town built on a kopje (an eccentric thrust of hard rock). Cycle route K1 is a high-quality dedicated path that runs right up Karolia from Santjana to the mountains and visits important sites and cities. On this branch line, trains have cycle spaces installed to facilitate day trips and cycle tourism. It's considered important to make alternatives to car use more attractive here to protect the environment in this landscape hence the lack of roads. Numerous species of water birds, aquatic reptiles and insects live here. Very occasionally river dolphins swim this far north from the coast, hunting fish.
