... was determined. The research results indicate relation between the location of nature conservation type and house investments. Introduction According to the concept of sustainable development, environmental and natural values must coexist with other objects to a certain degree. The requirement of reconciling different conditions also refers to reconciling natural values and investment development, including housing investments. In this context, the application of nature protection instruments, including designation of nature protection forms, may constitute one of the collision points of different qualities. The purpose of the article is to define the relationship between the development of housing investments and the degree of terrain coverage with nature protection forms. It will involve both a statistical analysis of the data covering the West Pomeranian Province, as well as an extensive reflection concerning the contact points of both these spheres. The subject of research concerns new house investments development in districts, depending on the degree of their coverage by the form of nature protection. In order to achieve the research objective, the data concerning the number of building permits issued in individual years for housing investments along with the data concerning the degree of coverage of districts with nature protection forms were gathered. Following that, on the basis of a correlation analysis, an attempt was undertaken at defining the scope of correlations existing between such data -both in all the districts of the West Pomeranian Province, as well as in the districts featuring specific properties from the point of view of the research assumptions. Research results and discussion Development of housing investments The need for the development of housing investments is emphasised and implemented in the policy of many countries (Cowem T., 1998) . Recent solutions implemented in Poland can serve as an example of that. Those solutions raise numerous doubts of procedural nature as well as doubts related to their compliance with the system of land management. Nevertheless, the above does not change the fact that the development of housing investments, from the perspective of the national economy, social needs related thereto, is fully desirable. Presently it is demonstrated in Poland in particular through the following solutions proposed: • the creation of National Public Real Estate Resources. The implementation of investments related to those resources and renting the real estate from those resources would be aimed, on the one hand, at offering facilitations for an investor, and on the other hand, at creating rent offers for a community; On the grounds of preliminary analyses, further studies were conducted (Tab. 4). A Pearson correlation coefficient was determined in the following data pairs: • the number of building permits issued for one-family buildings and a percentage share of the district covered by nature protection forms; • the number of building permits issued for multi-family buildings and a percentage share of the district covered by nature protection forms. The choice of data is justified in terms of the fulfilment of the research objective. It was assumed that the location of nature protection forms may constitute one of the factors affecting the scope of housing investment implementation. That is why it is justified to compare both groups of data.
