The aim of this paper is to evaluate the activity of local governments’ planning and investment service in the environmentally valuable areas of Podlaskie Voivodeship. Spatial planning at the local level is extremely important, especially in the environmentally valuable areas. It makes it possible to preserve the natural environment for future generations and to maintain ecological processes. However, protective measures should not disturb municipal investments. One of the appropriate solutions is the introduction of local land development plans – a framework of rational management of natural resources and of marketing development. This is particularly important in the areas of municipalities which, beside ecological functions, play an important role in the development of tourism and transport, and are situated in suburban areas.
